**The
Invention of Hans Coler, Relating to an Alleged New
Source of Power**

**I. Object of Visit
& Summary ~**

Coler is the inventor of
two devices by which it is alleged electrical energy may
be derived without a chemical or mechanical source of
power. Since an official interest was taken in his
inventions by the German Admiralty it was felt that an
investigation was warranted, although normally it would be
considered that such a claim could only be fraudulent.

Accordingly Coler
was visited and interrogated. He proved to be cooperative
and willing to disclose all details of his devices, and
consented to build up and put into operation a small model
of the so-called "Magnetstromapparat" [Magnet Power
Apparatus] using material supplied to him by us, and working
only in our presence. With this device, consisting only of
permanent magnets, copper coils, and condensers in a static
arrangement he showed that he could obtain a tension of 450
millivolts for a period of some hours; and in a repetition
of the experiment the next day 60 millivolts was recorded
for a short period. The apparatus has been brought back and
is now being further investigated.

Coler also discussed
another device called the "Stromzeuger", from which he
claimed that with an input of a few watts from a dry
battery an output of 6 kilowatts could be obtained
indefinitely. No example of this apparatus exists today,
but Coler expressed his willingness to construct it, given
the materials, the time required being about three weeks.

Opportunity was
taken to interrogate Dr. F. Modersohn who had been
associated with Coler for ten years and had provided
financial backing. He corroborated Colers story in every
detail.

Neither Coler nor
Modersohn were able to give any theory to account for the
working of these devices, using acceptable scientific
notions.

**II. Historical
Notes ~**

**1. *The
"Magnetstromapparat"***

![](coler1.gif)  
![](coler2.gif)  
![](coler3.gif)

This device consists of
six permanent magnets wound in a special way so that the
circuit includes the magnet itself as well as the winding
(See Figure 1). These six magnet-coils are arranged in a
hexagon and connected as shown in the diagram (Figures 2
& 3), in a circuit which includes two small
condensers, a switch, and a pair of solenoidal coils, one
sliding inside the other. To bring the device into
operation, the switch is left open, the magnets are moved
slightly apart, and the sliding coil set into various
positions, with a wait of several minutes between
adjustments. The magnets are then separated still further,
and the coils moved again. This process is repeated until
at a critical separation of the magnets an indication
appears on the voltmeter. The switch is now closed, and
the procedure continued more slowly. The tension then
builds up gradually to a maximum, and should then remain
indefinitely. The greatest tension obtained was stated to
be 12 volts.

The
"Magnetstromapparat" was developed by Coler and von Unruh
(now dead) early in 1933, and they were later assisted by
Franz Haid of Siemens-Schukert, who built himself a model
which worked in December 1933. This was seen by Dr. Kurt Mie
of Berlin Technische Hochschule and Herr Fehr (Habers
assistant at the K.W.I.) who reported that the device
apparently worked, and they could detect no fraud. One model
is said to have worked for 3 months locked in a room in the
Norwegian Legation in Berlin in 1933. No further work
appears to have been done on this system since that date.

**2*. The
"Stromzeuger"***


![](coler4.gif)

![](coler6.gif)

This device
consists of an arrangement of magnets, flat coils, and
copper plates, with a primary circuit energized by a small
dry battery. The output from the secondary was used to light
a bank of lamps and was claimed to be many time the original
input, and to continue indefinitely. Details of this
circuit, and a theory as to its mode of operation were given
(summarized in Appendix I).

In 1925 Coler
showed a small (10 watt) version to Prof. Kloss (Berlin),
who asked the Government to give it a thorough
investigation, but this was refused, as was also a patent,
on the grounds that it was a "perpetual motion machine".
This version was also seen by Profs. Schumann (Munich)
Bragatad (Trondheim) and Knudsen (Copenhagen). Reports by
Kloss and Schumann are translated in Appendices II and III.

In 1933 Coler and
von Unruh made up a slightly larger model with an output of
70 watts. This was demonstrated to Dr. F. Modersohn, who
obtained from Schumann and Kloss confirmation of their tests
in 1926. Modersohn then consented to back the invention, and
formed a company (Coler g.m.b.h.) to continue the
development. At the same time a Norwegian group had been
giving financial support to Coler, and these two groups
clashed. Modersohns connection with Rheinmetall Borsig, and
hence with the official Hermann Goering combine gave him an
advantage in this. Coler then in 1937 built for the Company
a larger version with an output of 6 kilowatts.

In 1943 Modersohn
brought the device to the attention of the Research
Department of the O.K.M. The investigation was placed under
the direction of the Oberaurat Seysen, who sent Dr. H.
Frohlich to work with Coler from 1.4.43 to 25.9.43. Frohlich
was convinced of the reality of the phenomenon, and set
about investigating the fundamentals of the device. He
apparently concentrated on a study of the energy changes
which occur on the opening and closing of the inductive
circuits. At the end of the period he was transferred to
B.M.W. to work on aerodynamic problems and is now working in
Moscow.

In 1944 a
contract was arranged with the O.K.W. with Continental
Metall A.G. for further development, but this was never
carried out owing to the state of the country. In 1945 the
apparatus was destroyed by a bomb, in Kohlberg, whither
Coler had evacuated. Since at that time Coler had been
employed, sometimes as an engineer, sometimes as a laborer.
Modersohn had severed his connection with Rheinmetall
Borsig, of which he had been a director, and was working for
the Russian authorities as a consultant in chemical
engineering.

**III. Report ~**

**1.
Interrogation of Coler ~**

Coler was
questioned first about the history of his invnetions, when
the details above were given.

He was then
questioned about the theory of the devices, but he was
unable to give any coherent suggestions as to the mechanism.
He sated that his researches (apparently conducted with
crude apparatus) into the nature of magnetism had lead him
to conclude that ferro-magnetism was an oscillating
phenomenon, of frequency about 180 kilohertz. This
oscillation took place in the magnetic circuit of the
apparatus, and induced in the electrical circuit
oscillations the frequency which of course depended on the
values of the components used. These two phenomena
interacted, and gradually built up the tension. As the
mechanism was not understood the proper arrangement could
not be worked out, but had to be arrived at by experiment,
and the apparatus had to be brought into adjustment by
similar trial and error methods. Coler stated that the
strength of the magnets did not decrease during the
use of the apparatus; and suggested that he was tapping a
new sort of energy hitherto unknown "Raumenergie"
(Space-energy). Coler gave a resume of the work done by Dr.
Frohlich for the O.K.W., and produced a copy of Frohlichs
report, written jointly with himself (translation reproduced
in Appendix IV) and a report of his own (part of which is
given in Appendix V).

Coler was asked
if he would consent to build models of these devices if
material was made available. He agreed that he could do
this, and stated that it would take one week to construct a
"Magnetstromapparat", and a month to construct a
"Stromzeuger". Accordingly we supplied the magnets,
condensers and copper wire needed for the former, and Coler
proceeded to build an apparatus as discussed in Section 3. A
list of materials required for the "Stromzeuger" was drawn
up by Coler.

**2. *Interrogation
of
Dr.
F. Modersohn***

Modersohn was
questioned about the history of these devices, with which he
had been concerned financially, and corroborated the details
given by Coler. He stated that he had at first disbelieved
Coler claims but had taken great precautions to eliminate
fraud. He had seen the 70 watt "Stromzeuger" working on a
number of occasions, and had taken it while working from one
room to another. All parts were visible and nothing was
hidden. As he was himself not expert he had tried to get
experts to examine it thoroughly, but reputable scientists
either refused to have anything to do with it at all, or
else were more concerned to find a fraud than to see how it
worked. The exception was Dr. Frohlich, who was convinced of
the reality of the effect, and who also believed that the
secret was to be found in the special inductive circuit
used. He had made experiments to test his ideas, but
Modersohn denied knowledge of the results. Modersohn was
extremely methodical, and showed his files on the subject:
these contained copies of all letters and reports concerning
the device, since 1933.

**3. *Construction
&
Testing
of the "Magnetstromapparat"***

In our presence
and with material supplied by us (some brought from England
and the rest bought locally) Coler built an apparatus as
shown in Figures 1, 2, and 3. It is to be noted that some
magnets are wound in a clockwise direction looking at the N
pole (called left) and others in an anti-clockwise
direction (called right). The magnets were selected
to be as nearly equal in strength as possible, and the
resistance of the magnet-coil combination was checked after
winding to see that this also was uniform (about 0.33 ohm).
The physical arrangement was as shown in Figure 2, in a
breadboard style. Measurements of voltage and current across
A-B were made with a Mavometer. A mechanical arrangement of
sliders and cranks for separating the magnets evenly all
round was made up.

On 1.7.46
experiments were being continued after three days of
fruitless adjusting, and when the magnets were at a
separation of about 7 mm., the first small deflection was
noted (about 9 a.m.). The switch was closed and by slow
adjustment of the sliding coil, and by increasing the
separation of the magnets to just over 8 mm., by 11 a.m. the
tension was raised to 250 millivolts and by 12.30 p.m. it
was 450 millivolts. This was maintained for another 3 hours
when a soldered tag became disconnected, and the meter
slowly dropped back to zero. Soldering up the broken
connection did not restore the tension. The magnets
were closed up and left overnight and the same procedure for
finding the adjustment was repeated on 7.24.46. After about
three hours a deflection of 60 millivolts was obtained; this
was maintained for more than 30 minutes, but then decreased
to zero when further adjustments were tried.

During all this
work the model was completely open, and nothing could be
hidden in it. The breadboard and meter could be picked up
and moved round the room, tilted, or turned, without effect.

The apparatus
would appear to be too crude to act as a receiver of
broadcast energy, or to operate by induction from the mains
(the nearest cable being at least 6 feet away), and the
result for the moment must be regarded as inexplicable.

**IV.
Conclusions ~**

1. It was judged
that Coler was an honest experimenter and not a fraud, and
due respect must be paid to the judgment of Frohlich in the
matter as deduced from his report to Seysen.

2. The result
obtained was genuine in so far as could be tested with the
facilities available, but no attempt has yet been made to
find an explanation for the phenomenon.

3. It is felt
that further investigation by an expert in electromagnetic
theory is warranted, and that Colers offer to construct a
model of the "Stromzeuger" should be taken up.

**Appendix I ~
Summary Account of the "Stromzeuger"**

1. The basic
principle is that an electron is to be regarded not only as
a negatively charged particle but also as a South magnetic
pole.

The basic element
is that of an open secondary circuit, capacity loaded,
inductively coupled to a primary circuit. The novel feature
is that the capacities are connected to the secondary core through
permanent magnets, as shown:

It is claimed
that, on switching on the primary circuit, "separation of
charges" takes place, i.e., Magnet 1 becomes positively
charged and Magnet 2 becomes negatively charged, and that
these charges are "magnetically polarized" when they are
formed, owing to the presence of the magnets. On switching
off the primary circuit a "reversing current" flows in the
secondary, but the magnets "do not exert a polarizing effect
on this reversal".

2. Two of these
basic elements are now placed together making a double
system or stage with the plates close together in parallel
planes as shown:

The secondary
windings are both exactly equal and wound in a direction
such that on switching on the primary coil the electrons in
the secondary coil flow from P1 to P2
[P = Plate] and F1 to F2 [F = "Flat
Spool"].

It is then stated
that system merely has an inducing effect, and the useful
current comes into existence in the system.

3. A single stage
cannot be effective but two stages connected so that the
numbers of effective North and South poles are equal will
provide a basic working arrangement. More double stages can
then be added to provide higher outputs.

4. It is then
stated that as well as the normal electrons flowing from the
battery and from induction when the circuit is opened or
closed, "space electron" flow from "repelling spaces" to
"attracting spaces" between the plates, but this theory I
was unable to follow any further.

**Appendix II ~
Translation of Report by Professor M. Kloss (Berlin) on
Tests on the Apparatus, constructed by Captain Coler
(dated 4 March 1926)**

On the 3rd
of March I have on request inspected the apparatus
constructed by Captain Coler, and I undertook some tests
regarding its efficiency. Professor Dr. R. Franke from the
Technical College of Berlin was present at these tests.

The apparatus, in
its construction already known to me from a previous
inspection, consists of:

a double row
system of copper plates,   
a double-row system of flat
spools,   
and a system of
electromagnets,

to whose cores
silver wires are attached and through which branch currents
of the plate-system are conducted. For each of the three
systems a 3-part accumulator battery of 6 volts/6.5
ampere-hours capacity is provided. The plate-circuit and the
spool circuit are parallel so that the two batteries
appertaining thereto can also be replaced by a single
battery. This was ascertained towards the end of the tests
by switching off the one battery while the apparatus was
working.

When asked why
two batteries were used at all, Capt. Coler declared that
for starting the apparatus a double battery is necessary to
get a second charge-impetus after exciting with the one
battery, and this for releasing the peculiar character of
the apparatus. A test made towards the finish of a series of
trials confirmed this assertion in as much as the mechanism
could not be started with the single battery; on the
contrary, the "adjustment" of the mechanism got disturbed.

Current-indicators
are built into each of the three circuits mentioned, as well
as volt-meters, behind some switch resistances necessary for
the "adjustment". Between the open ends of the two plate and
spool-systems there are the terminal clamps for the
effective circuit for whose loading 3 bulbs of 8 volts are
provided. The apparatus was then put into action and above
all the load was tested with the aid of the built-in
instruments, that is on being loaded with 2 lamps, 3 lamps
and running light. Thereupon and by means of
precision-instrument (continuous-current type) Siemens &
Halske Nr. 423820 the indications of the built-in
instruments were controlled by switching on the mentioned
precision-instrument in turn to the single circuits, that is
direct to the one terminal clamp of the battery, in order to
ascertain if perhaps through any by-connections with the
batteries, not conspicuous at once, more current might be
received than the built-in instruments were showing. The
tests showed a sufficient conformity within the bounds of
measuring accuracy.

Finally the same
instrument was switched on also to the effect circuit,
whereby some greater differences with the instruments built
into this circuit were shown; on the other hand, however,
not such differences as to alter fundamentally the total
result in any way.

In order to find
out besides, whether the output current might be identical
with a wave-current overlapping continuous current, the last
control test was repeated by using a hotwire instrument
furnished by me, make of Hartmann & Braun, Nr. 254159.
In case there would have been such wave-currents, the
hotwire instrument would have had to indicate a bigger
current than was shown by the continuous-current instrument.
In reality, however, a somewhat smaller current was found
was when employing the hotwire instrument. This may be
explained by the fact that the inner resistance of the
instrument is about 10 times greater than that of the
continuous-current instrument, so that when switching on the
hotwire instrument the load of the apparatus was somewhat
lessened. The difference between 3.08 ampere measured with
the continuous-current instrument as compared with 2.95
ampere measured with the hotwire-instrument is easily
explained when taking into account the divergences of the
two instrument resistances. Therefore one can infer from
this test that in the load-circuit we have to deal with real
continuous current.

The results of
the tests are compiled in the annexed table.

The figures show
very well that the consumption of energy in the external
circuit is greater than the energy taken from the batteries.
According to the circuit, produced by Captain Coler, which
within this short time I could not check in all its parts,
the magnet-exciting circuit is fed by a special battery,
completely separated from the other two circuits.
Consequently, a direct comparison of efficiency and
consumption of the apparatus would mean that only the sum of
current of the plate circuit and of the spool circuit would
count. After the established estimates with my own
instrument and on a load of 3 bulbs, there was resulting a
current from the two mentioned batteries of 0.215 + 0.070 =
0.285 ampere. At the same time the three bulbs consumed ca.
3.7 ampere, according to the built-in instruments, which is
about 0.2 ampere too much as was proved later on by a
control of this instrument, so that the real consumption has
been about 3.5 ampere at a tension of about 2.3 volt.

The reception of
current from the two batteries in this case consequently was
1.7 watt while the consumption of the bulbs amounted to
about 8 watt. Especially striking in this connection is the
considerably higher current-power in the bulb-circuit being
about 12 times bigger than the current coming from the two
batteries.

We have also
absolutely made sure that from the batteries no other
conductors led to the apparatus than those into which my
instrument was built-in. The fact that an increase of power
from the battery to the terminal clamps of the effective
circuit in the plate-system takes place, could, indeed, not
be tested on the different parts of the apparatus by a
direct measuring of the power itself, because Mr. Coler
declared that when switching on an instrument in the
interior of the system, probably the "adjustment" would be
disturbed.

I have therefore
tested the decrease of tension in the single plates on a
load of three lamps by means of a millivolt-meter, make of
Hartmann & Braun, Nr. 462375, in order to get at least
in an indirect way an explanation for the increase of
current. This examination showed a remarkable increase of
tension-losses with a distinct maximum on the third-last
plate of the one row. These estimates too are compiled in
the table at the end of this judgment.

***Results*
~** The result
of the investigation showed an astonishing working of the
apparatus, which, without further researches cannot be
explained or compared with the hitherto known
characteristics.

Regarding the Cause
of the observed characteristics, especially the solution of
the question, where the energy in the apparatus originates,
no explanation can be given yet, after the short and
simple tests.

Solely the
conjecture can be expressed that the magnet-system is the
source of the energy. It therefore seems desirable to clear
this point by further thorough and systematic examinations.
For this purpose the proposition of Mr. Coler to construct a
bigger apparatus is very sensible, an apparatus, into which
from the beginning measuring-instruments should be built in
the respective parts of the single circuits in order to
enable the "adjustment" of the apparatus including these
instruments.

A judgment for
the possible utilization of the phenomena, observant in the
apparatus, from the economical point of view, I am, of
course, not able to pass on after these short tests. This
question could only be answered after some lengthened and
permanent tests, by which could be established what
productiveness the source of energy, existent in the
apparatus will show, especially if the magnets, in case they
are the supports of the energy-source would wear out after
some time, and at what expense each time they could be
replaced by new ones.

Above all,
however, it appears important that the part or parts of the
apparatus, being possibly responsible for causing the
observed phenomena, should be taken out in a way as simply
as possible and be submitted to an examination in all
directions.

Before finishing
this, I wish to say that the results of the test are put at
the disposal of Captain Coler for which reason I enclose a
copy herewith.

I should like to
ask, however, the gentlemen in question not to mention my
name and that of Professor Franke nor divulge the results of
our tests without our express consent, or to make them known
publicly and above all not in the press.

Signed,

Dr. Ing. M. Kloss

too high.

The control

instrument (millivoltmeter) for current and tension
measurings. The control instrument H&B 234159 is a
hotwire instrument.

**Appendix III ~
Translation of a Report by Professor W.O. Schumann
(Munich) on the examination of the apparatus of Mr. Coler
in berlin on the 19th & 20th
march, 1926 (dated 3rd April 1926)**

The apparatus in
question principally consists of two parallel connected
spools, which being bifiliarly wound in a special way, are
magnetically linked together. One of these spools is
composed of copper sheets (the spool is called the plate
spool), the other one of a number of thin parallel connected
isolated wires (called: spool winding), running parallel at
small intervals to the plates. Both spools can be fed by
separate batteries; at least two batteries are necessary to
put the spools to work.

The spools are
arranged in two halves each, according to the bifilar
winding system. The batteries are attached to the starting
points, and the current-receivers to the parallel connected
ends. Inter-communications are connected between parallel
windings of the two halves of the plate spool which contain
iron rods with silver connections. These rods are magnetized
by a special battery through applied windings (called:
exciter windings).

According to the
statement of the inventor, the production of energy
principally takes place in these iron rods, and the
winding of the spools plays an important part in it.

As far as it was
possible I convinced myself of the conformity of the circuit
with the mechanism. The exciter winding is electrically
completely separated from the other windings, which was
proved when testing the apparatus while being devoid o
tension, as well as when testing it while being at work with
the aid of an Ohmmeter and a millivoltmeter.

In order to
ascertain possibly concealed sources, the apparatus was
searched with a millivoltmeter, without using any external
batteries. No effect was perceptible. Besides the apparatus
was carried from one room through a corridor to another one
in the establishment to exclude the possibility of any
secret connection to the mains.

Installed in the
apparatus were three current meters for the currents from
the three batteries, and furthermore current and volt meters
of the soft iron type for the current receivers. One and two
bulbs respectively were employed for this purpose. Besides
there were at disposal one precision milliampmeter of the
S&H turn spool type, also employable as ammeter and
voltmeter (called: Dr. Sp. C), and a turn spool
millivoltmeter of the A.E.G., an ordinary laboratory
instrument, also employable as a voltmeter (called: Dr. Sp.
A.E.G.C.).

While the
apparatus fed two bulbs, the current delivery of the three
current-supplying batteries was measured directly at the
terminal clamps. The results are as follows:

1. Current of the
plate battery: 48 ma

2. Current of the
spool battery: 39 ma

3. Current of the
exciter battery: 170 ma (Dr. Sp. S & H.C.)

The indications
of the built-in instruments were in unison with the
statements of the S&H instrument. The total capacity of
the batteries of three elements each: 0.257 x 6 = 1.542 watt
(the tension of the batteries in reality being below 6
volt). The possible capacity of the two bulbs according to
the built-in soft-iron instruments was 3A x 3.5 V, that is
10.5 watts which means the 6.7 fold of the above-mentioned
capacity.

Thereafter only
one bulb was connected, and a second one, exactly of the
same type, was regulated with a special accumulator battery
to get the same light. All currents were measured with the
"Dr. Sp. S & h C.", all tensions with the "Dr. Sp.
A.E.G.C." and not with the built-in instruments.

1. Current of the
plate battery: 28 ma

2. Current of the
spool circuit battery: 23.5 ma

3. Current of the
exciter battery: 180 ma

That means, if
reckoned with a 6 volt battery tension, 6 x 0.232 = 1.392
watt. The possible capacity of a bulb, fed by a special
battery, and showing the same lightpower was 4.5 volt x 1.5
A = 6.75 watt. Proportion of both efficiencies ca. 4.85.

Both instruments
used for testing (measuring) from S&H and from the AEG
were than compared with each other by a current-voltmeter,
the highest possible deviation being less than 10% which can
therefore scarcely influence the result.

The apparatus,
according to the statement of the inventor, is adapted now
for current increase. The bulb-tension of 3-5 volt is less
than the tension of the feeding batteries. By changing over
in the interior it would also be possible to use it for an
increase in tension.

Then there was
made a test with the aid of the Dr. Sp. Millivoltmeter from
the AEG to try the decrease of tension in the single winding
halves of the plate spool on the right as well as on the
left side of the mechanism (The form of the spool is that of
a long small rectangle).

The tensions are
distributed very unequally which must be due to current
increases and decreases through the iron cores.

Further
measurements on the single parts could not be carried
through for the reason of getting impeded by the built-in
parts of the apparatus. Any variations of the
regulation-resistances were also not undertaken, because the
inventor stated that the apparatus in its installation was
very sensitive, especially with regard to the magnetic
conditions of the iron cores, and that a wrong treatment
[internal measurements] would cause interferences which
would be wearisome and very difficult to be eliminated.

The next day I
got a Hotwire-voltmeter "H&B" (called: Dr Sp TH) at the
Technical High School of Charlottenburg. With these
instruments and those of the previous day the following
tests were made:

1)  Plate
circuit: 28 mA (Dr Sp TH)

Lamp current:
1.52 A (Dr Sp S&H C); 1.60 A (H Dr TH); 1.3-1.4 A
(Built-in soft-iron instrument)

Lamp tension:
4.05 V (H Dr TH); 4 V (Built-in soft-iron instrument)

2) Spool circuit:
28.5 mA (Dr Sp TH)

Lamp current:
1.47 A (Dr Sp S&H C); 1.56 A (HDTH)

Lamp tension: 3.8

3) Exciter
circuit: 0.173 A (Dr Sp S&H C)

Lamp current: 1.5
A (H Dr TH)

Lamp Tension: 3.8
V (H Dr TH)

Once again a
comparison of capacity was carried through by using an equal
lamp to that in the apparatus with an accumulator, and
bringing it to the same brightness, as judged by the eye.

Lamp in
accumulator circuit:

Tension: 4 V (Dr
Sp S&H C); 3.3 V (Dr Sp AEG C)

Current: 
1.5 A (Dr Sp S&H C)

Lamp in
apparatus:

Tension: 3.85-4.0
V (H Dr TH)

Current: 1.59 (H
Dr TH)

Current in spool
circuit: 27-28.5 mA (Dr Sp TH)

Thereafter the
instruments with the measured current and tension figures
were compared with each other:

1. Tensionmeter
parallel on two accumulators:

Dr Sp AEG C: 3.2
V

H Dr TH: 3.8 V

Dr SP S&H C:
4.2-4.2 V

2.
Voltaelectrometer in line:

H Dr TH: 1.47 A

Dr Sp S&H C:
1.46-1.47

Even when taking
into account the errors of the instruments, the resulting
multiplication of energy, in principle, does not undergo any
alteration through the apparatus. Judging from the
conformity of the hotwire and turnspool instruments in the
lamp circuit, the inference is to be drawn that principally
it is continuous current one has to deal with. A test of
current from the batteries by way of hotwire measurement was
not possible.

As a striking
fact it should be mentioned that the spool circuit having
been at first always switched on alone, received a current
of 104 mA. As soon as plates and exciter circuit
additionally and simultaneously were turned on, as,
according to the inventor, the apparatus demands it, the
current in the spool circuit comes down to about 27 mA.

A definite
judgment about the apparatus must be reserved by me until
all parts have been singly tested, and until variations in
the connections in the load and and circuit have been
undertaken.

After the present
examination, carried through as carefully as [possible], I
must surmise that we have to face the exploitation of a new
source of energy whose further developments can be of
an immense importance. The apparatus was visible and
accessible in all its essential parts. The inventor agreed
quite willingly to each trial in so far as, according to his
statement, no harm could be done to the working of the
apparatus.

I do not believe
in a deception. I deem it expedient to put the apparatus to
a further test, and I believe that a further development of
the apparatus and an assistance, given to the inventor, will
prove justified and of great importance.

**Report by Hans
Coler & Dr. Heinz Frohlich (Abstract) ~**

Some years ago an
apparatus (the Coler apparatus) was empirically developed,
which according to a series of reports by well known
scientists and practical engineers, was able to deliver a
considerably higher electrical output than the input
necessary to excite the electromagnetic field of the
apparatus.

Due to the lack
of sufficient knowledge of the complicated activity within
the apparatus, and of the impossibility of explaining this
in known terms, the success in starting the apparatus
depended on happy accident.

With the support
of the OKM an attempt was made to examine and measure the
activities in the Coler apparatus. Due to lack of sufficient
technical and physical means, we did not at first succeed in
starting it. This work, however, led to valuable knowledge
and information.

It is therefore
necessary, through a systematic basic research, to transfer
the adjustment and other necessary procedures for starting
the apparatus, from the domain of accident into a practical
experimental procedure which is at any time reproducible.

*1. History ~*

During the year
1923 to 1926 the undersigned, Captain Hans Coler, basing his
work on lay theories of electromagnetic and inductive
activities, has developed an apparatus for generating
electrical energy, which delivered a considerably higher
electrical output than was necessary to excite the primary
fields of the apparatus. This development was carried out
merely empirically and due to the lay procedure, without
recording measurements or making diagrams.

This apparatus
was the subject of numerous examinations by scientists and
practical engineers, who in their reports, almost without
exception, had to admit an energy surplus or energy
multiplication without being able to explain the process by
present knowledge. The inventor also could not give an
explanation due to lack of sufficient knowledge of the
activities in the apparatus (See reports by Professors Kloss
and Schumann on record at the OKM).

Due to unpleasant
differences with the financiers, mostly foreigners, and a
nervous breakdown of Coler, because of these, the apparatus
and original theories were lost.

Upon resumption
of the experiments at a later date the effect was
occasionally successfully reproduced (see report by Dr.
Modersohn concerning events at New Year 1936-7) which,
however, evidently due to disturbances of the adjustments,
could not be maintained because sufficient measurements were
not taken. The outbreak of war then put a temporary end to
the experimental work.

*2.
Intervention of the OKM ~*

In 1942, Coler
and Dr. Modersohn made an application to the OKM to supply
them with materials for further work, hoping that by simple
technical means, the apparatus could be made to work.

Their aim was to
produce a working apparatus, which could be shown to the
Fuhrer of Germany, leaving the measurement of all activities
of the apparatus to a later date.

The OKM approved
the application and sent sufficient material to build the
apparatus and lent the inventor ordinary amperemeters,
voltmeters, and necessary tools. It was found, however, that
due to the overload of work upon them at this time, their
spare time work was not sufficient to secure quick results.
The OKM therefore procured their release from other work, to
allow a more intensive, and, due to the cooperation of Dr.
Frohlich, who had experience in physical measurements, a ore
scientific approach.

The newly
developed apparatus could not be made to work, however,
because of the lack of thorough knowledge of the activities
in the apparatus which now appeared to be very complicated.
Valuable knowledge and promising signs, owever, were
obtained.

*3. Short
Description of the Apparatus ~*

The apparatus
consists of three principle circuits which are inter-wound
and inter-coupled (verkoppelt) in a peculiar way. Some of
these are divided again into single subsidiary circuits
which evidently have all to be brought into resonance with
one another.

The principal
circuits (called the anchor) in which the energy gain
probably occurs, consists of metal plates between which
transformer coils are connected, the whole being connected
to one large coil plate (Plattenspule). On each of the
single windings on this is coupled a large flat coil
(Flachspule)(called field). These flat coils are interwound
in two groups; these groups represent the turns of a
transformer. This couples, on one hand on the flat coils of
the other group (as secondary coils), and on the other hand
on the anchor-plate coil, which is placed between them. The
third electrically independent circuit (called the directing
circuit)(Steurkreis) regulates this transference. Figure 1
[not included in the BIOS Report] shows diagramatically and
in plan these interwound parts (anchor in red, field in
green, directing circuit in blue). Figure 2, the so-called
basic diagram, shows the connections between these different
parts. This basic diagram shows the conditions necessary for
self-interruption. In consequence of this arrangement,
different types of currents are created in different
conductors (pulsed DC, AC, etc.).

The transformer
coils, connected between the anchor plates, are connected in
a peculiar way through thin permanent magnet rods. Their
main object seems to be to pre-magnetize the transformer
cores; it is, however, very probable that they are also
connected with the Barkhausen Effect, which will be
mentioned later.

*4. Experiments
carried out ~*

From the
reflections which led to the diagram of the apparatus
described above, the reality of some physical effects was
assumed, which partly from the inventor himself, and partly
also from the scientists who had examined the working
apparatus, were stated as a possible or probable explanation
of the phenomenon observed.

As these
hypotheses has not been examined by measurements, it seemed
suitable, for further development of the apparatus, to
clarify these questions by further experiment, so far as was
possible with the means at our disposal.

The experiments
carried out are described below.

**Experiment 1 ~**

If a single layer
solenoid is connected to a battery, a current begins to flow
at the moment of connection, which is known to rise
exponentially, until it reaches a constant maximum
determined by the voltage of the battery and the resistance
of the circuit. Every point on the current/time curve
corresponds to a magnetic field, which is dependent on the
dimensions of the solenoid. At the moment of connection the
electrons do not begin to flow at the same time in all parts
of the coil, because the electromagnetic wave (Storungwelle)
travels with the velocity of light. The electromagnetic
field at different parts of the coil also builds up with a
corresponding time difference. Now in a right hand wound
coil a north pole is produced at the end where the current
enters (the current direction is taken now and hereafter to
be the direction of flow of the electrons, i.e., from
negative to positive), in a left hand coil a south pole is
similarly produced. In the first case the building up of the
magnetic field proceeds from the north pole to the south, in
the second place from the south to the north, or in other
words: The direction of the building up of the field is in
one case with the direction of the flow of the field and in
the other against it.

Question: Is the
velocity of the building up of the field different in these
two cases, although the data of the coils is the same except
for the direction of winding? This means, is there a
difference in the time in which the currents are reaching
their maximum value?

If such an effect
could be found, it must show itself in one of the following
ways:

(a) The coils
must have different apparent resistances (scheinwiderstand).
By measurement of voltage and current the apparent
resistance of ten right-handed and ten left-handed coils was
tested with a Phillips-Schwebungs-Summer instrument. The
apparent resistances were the same within an experimental
error of about +/- 1%.

(b) Other
conditions being the same, the coils must induce different
potentials across a secondary coil, when connected to a
battery. Measurements were made with a cathode ray
oscillograph from Siemens and Halske. The induced potentials
were the same. It can therefore be proven that no such
effect exists.

**Experiment 2 ~**

Given: a solenoid
consisting of two windings, one upon the other, of the same
length and number of turns, enclosing a soft iron
cylindrical core. Firmly attached to one end of the core is
a pre-magnetized steel rod. If an alternating current is
passed through one of these coils, acting as primary, the
residual magnetism of the steel rod is strengthened during
one half cycle, through the magnetism induced in the core,
during the other half cycle it is weakened. If now the other
winding is connected in series with the pre-magnetized steel
rod -- as secondary coil -- in such a way that the secondary
current must pass through the magnet, one half cycle of the
secondary current must be more or less subdued; in other
words, a rectifying effect must be created (It may be
remembered that according to measurements by Professors
Kloss and Schumann, a high frequency pulsed direct current--
about 180 KHz -- is flowing in the output resistance of the
apparatus, for the creation of which no other explanation
seems possible).

Unfortunately,
the testing of these effects could only be made with tuned
frequency (Tonfrequent) alternating current, with the use of
which no such phenomenon could be seed when using measuring
instruments and a cathode ray oscillograph.

The question is
open whether, and if so in what way, an influence on the
electron movement exists through the oscillation of the
magnet molecules by high frequency alternating fields,
especially of such an impulse-like character.

**Experiment 3 ~**

Previous
measurements, from the year 1937, made by the inventor and
his assistant, Dipl. Ing. Rudolf Hingst, had shown the
following effect. Given two solenoids each consisting of two
coils one upon the other, of the same length and number of
turns, one winding of one solenoid is connected in series
with one winding of the other, wound in the same sense, and
an intermittent direct current is passed through them. The
remaining windings, which are to be considered as secondary
coils, are also connected in series but wound in opposite
sense to one another. The induced secondary currents are
therefore similarly in opposition, and would, due to the
equal dimensions of the coils eliminate each other. The
measurements referred to above are said to have given the
result that in such a secondary circuit a considerable
direct current component exists which can be strengthened by
means of which we shall not go into here. And this
strengthening is to such a degree that the "secondary direct
current" is comparable to the primary current.

Testing of these
measurements, however, did not confirm them.

**Experiment 4 ~**

Besides the above
questions, uncertainty existed as to what part the above
described plate and flat coil plays in the function of the
apparatus, and how great is the mutual influence of the flat
coils upon one another? Of the flat coils upon the plates?
And finally of the plates between them? As the plates are
not only charged as condensers, but also have directed
currents passing through them it had to be assumed that
their mutual influence not only consisted of a condenser
effect, but that they also created a magnetic field.

It must first be
stated that the frequency of the "Summer" instrument at our
disposal (0-12 KHz) was not sufficient for measure the
mutual electromagnetic influence of the plates, due to the
low apparent resistance. This examination should be carried
out with high frequency alternating current. It was,
however, possible by the use of a highly sensitive
oscillograph as a valve voltmeter to measure the potential
induced by the flat coils on the individual plates, to
discover the induction currents in the plates, and also to
determine the value of the potential induced by the flat
coils on the plates in proportion to the currents created in
the plates from the current induced in the anchor coils (the
directing current was used as a primary winding in these
measurements, being connected to the Schwebungs-Summer).

It appeared that
the "Ankertrakte" AC or BD (See Figure 1) are not all to be
considered as oscillating circuits, but that the single
group systems, consisting of plate-to anchor coils-plate
already represent independent oscillation circuits.
According to this the apparatus contained ten such
oscillation circuits. The individual frequency of these
circuits and possible differences existing between them
could unfortunately not be measured, because, as already
mentioned, up to now only tuned frequency for excitation was
at our disposal. In order to make the apparatus work the
harmony of all oscillating circuits in their individual
frequencies would evidently be necessary -- at least within
certain limits determined by the suppression in question.
Such an adjustment can of course not be secured by the means
at our disposal at the present. The previous occasional
success must be considered as due to chance.

The mutual
influence of the flat coils upon one another could on the
other hand easily be examined because, despite the great
distance between the windings (25 mm), they have remarkably
great apparent resistance (about 200 ohms at 10 KHz).

It appeared that
the power factor (Ubertragungs-faktor) of both of the flat
coils wound 1:1 in consequence of their peculiar
interwinding (see Figure 1) have the astonishingly high
value of 0.85. The value of the power factor was at a
maximum at 10KHz, at which frequency the most favorable
matching of the impedence of the Summer was obtained.

The assumption
could easily be made that the power factor of the flat coils
upon the plates is still more favorable, but this
measurement can only be made with high frequency alternating
current.

Apart from the
great number of alternative arrangements and connections
between the different parts -- during the period covered by
this report eight different circuit diagrams were tested in
addition to the experiments above -- the following so far
unsolved problems are hindering success in making the
apparatus work:

(a) The influence
f the pre-magnetization and of the magnetizing effect due to
the battery current, upon the individual frequency of the
oscillating circuits.

(b) The influence
of the Barckhausen effect on the phase conditions of the
oscillations in the individual circuits and on the mutual
magnetic and electrical processes.

(c) The influence
on the movement of electrons in the pre-magnetized steel
rods by the high-frequency pulse-like field variations,
through the oscillations of the molecules of the magnets.

(d) The behavior
of the mutual effect between flat cols and plates in a high
frequency system.

*5. Conclusions
~*

After the
experience previously gained on the working apparatus, and
on the basis of the technical measurements and examinations
mentioned above, the picture of the way in which the
apparatus works is as follows:

Due to the
connecting of the batteries, a current impulse is induced in
the anchor circuit which chares the plates. The discharge
current from the plates causes electrical interruption of
short duration of the battery current in the field circuit,
which furthermore inductively interrupts, or changes the
direction of, the battery current in the directing circuit
or a short time. The electromagnetic field induced by this
process in the directing circuit by its dissipation, induces
over the field circuit a current in the anchor circuit
recharging the plates, and so forth.

Due to the
influence of the Barckhausen effect, each single process has
an impulse-like character, and the necessary change of phase
is produced to allow the regularity of the process.

Due to a source,
up to the present not investigated, and not explainable by
existing scientific theories, an additional quantity of
energy is freed during each cycle which leads to a continual
raising of the amplitude of the mutual processes, until the
magnet cores are saturated.

From the fact
that in the resistance of the apparatus pulsed direct
current is flowing (see Report by Professors Kloss and
Schumann), there is possibly an up to now unknown rectifying
effect, or alternatively the gain in energy is produced only
during one half of the cycle, either during the charging or
discharging of the plates. The activity in the apparatus
must take place in the ten oscillating circuits in a
phase-like manner. As mentioned above, no technical
means were available to make the necessary tuning
adjustments.

It is clear from
the above that the success of the inventor up to now could
only be due to chance, or happy accident. The necessity,
therefore, arises to transfer the apparatus from the state
of empirical development, with sufficient technical means
and based on results of an exact basic research, to a state
of working procedure which can be controlled.

*6. Further
Procedure ~*

In a simple
apparatus, possibly consisting of one oscillation circuit,
the problems mentioned in paragraph 4 should be cleared up,
the excitation of the oscillation circuit being caused by an
appropriate valve circuit. After clearing these problems, a
second oscillation circuit may be added, which will allow
the examination of the conditions necessary for the mutual
building up of effects.

It will then be
possible for the first time to go from external excitation
to self-interruption and a solely electromagnetic basis,
with the aim of bringing the apparatus in question to work
systematically.

**Appendix V: Extract
from Statement by Coler relating to Frohlichs
Experiments**

These fundamental
researches, which have made the first real and large
breach in the citadel of present scientific belief, will
now be described in detail. The installation shown in
Figure 14 [?] ws used in the experiments. A transformer,
with a ratio of 1:1 wa connected on its primary side
through a periodic make-and-break X to a DC source U.
Great care was taken to ensure that the make-and-break
funtioned smoothly, without backlash and uniformly, at
high frequencies and thus prodcued as clear and
unambiguous a result as possible.

![](coler7.gif)

On the secondary
side the coils S was connected with resistance R, a
reversible rectifier G, and a highly sensitive hot-wire
ammeter, form a circuit. The resistance R was large compared
with the apparent resistance of the coils S.

Switch Sch
allowed the switching of the rectifier G to be carried out
in such a manner, that in one case the half-wave of the
opening impulse, and in the other that of the closing
impulse, was transmitted. In order to prevent any possible
objection, that the iron had any influence on the results,
the whole transformer was out during the experiments and an
iron-free flat coils arrangement was used as the inductor
during these experiments. This eliminated all interference
and had excellent transmission properties. The required
sensitivity was attained in these measurements by using a
thermopile with the most sensitive milliammeter. After many
trials, the motor-driven interrupter of a Bosch ignition
magnet was used as make-and-break. This gave very uniform
and smooth interruption with a frequency of 100 Hz. The
result obtained with this experimental arrangement, which
eliminated all possible causes of later objections, was the
clear proof of a considerably larger energy during opening
(intake), compared with closing impulses. The energy was
determined by i2 from the measured current
intensity, and as the resistance R is large compared to the
apparent resistance of the coil, the objection, that the
opening impulse had a frequency spectrum of considerably
higher value than the closing impulse, could not hold good.

In order to
counter all other plausible and possible objections, the
processes were recorded by an oscillographic method.
Unfortunately the light strength of the available cathode
ray oscillograph tubes (Brauns tubes -- it was during war
time) did not suffice to produce perfect oscillograms.
Consequently, for the time being at least, this aid, which
would have completely removed all objections, had to be
dispensed with and a Siemens loop oscillograph was therefore
used. By choosing suitable loops, sources of error were
eliminated as far as possible, or at least kept within very
small limits.

The most careful
planimetric measurements again gave the same results as
those obtained with the experimental installation described
above, at least in principle, even though the percentage
difference of the quantity of energy in the opening and
closing impulses was slightly less in the measurements of
the oscillogram than those obtained from the thermopile. It
still amounted to an average of 10%, compared with 50% in
the measurements, so that errors in the planimetric
measurements are not to be assumed. Also, if this had been
merely a scattering of the results, a difference in favor of
the closing impulse must have occurred at least once.
However, the difference was always in favor of the opening
impulse. Any possible errors in the planimetric measurements
are controlled and avoided, by carefully cutting the figures
produced and weighing them on a most sensitive and accurate
balance.

Consequently this
observation can also be considered as a proof of the fact
that an energy difference exists. The circumstance that the
percentage of this unequality appears smaller in the
oscillographic measurements than in the thermal, which at a
power frequency of 100 Hz assuredly yield a sufficiently
accurate mean value, allowing also for the resistance ratios
of the rectifier, can readily be explained by the lag of the
oscillograph used, which is not even capable of recording
the considerable, but extremely short, energy peak of the
opening impulse. Although, therefore, the inertialess
cathode ray tube was not used in these measurements as a
final proof, I can consider my discovery of the energy
difference between the opening and closing impulse as proven
on the basis of Frohlichs experiments.

As this also
proves simultaneously, that my intuitively derived view,
based on my most primitive experiments, of these process has
proved correct, the reader will forgive me, if I consider my
other two results to be correct, until new, and above all
better explanations are found for the phenomena described.
This all the more, as my development of the "Space Energy
Receiver" was based on this and was successful.

**DE680761** **Anordnung zur Umwandlung von Gleichstrom in Wechselstrom** **Arrangement for converting direct current into
alternating current** **[ [PDF](de680761.pdf) ]** **Inventor:** **COLER HANS**  **Applicant:** **FRITZ MODERSOHN DR ING**  **CPC:** **H02M1/20**  **IPC:** **H02M1/20****1939-09-07**   
  
The invention relates to an arrangement for converting
direct current into alternating current using two direct
current sources and is characterized in that, on the one
hand, the negative and on the other hand the positive poles
of the current sources are connected by two series-connected
auxiliary resistors and each a consumer resistor that is
also connected in series. Furthermore, a bridge resistor and
a simple switch are provided between the conductor parts
lying between two adjacent auxiliary resistors, and a
periodically operating interrupter is arranged in a
conductor part connecting the positive pole of one power
source to the negative pole of the other power source. The
auxiliary resistors and the bridge resistance are preferably
adjustable. In order to obtain an alternating current with a
very low or completely absent direct current component,
assuming the same voltage of the two direct current sources,
all resistances are expediently dimensioned in such a way
that each of the two auxiliary resistors immediately
adjacent to the consumer resistors, together with the
associated consumer resistor, has the same resistance value
one of each of the other three resistors, namely the. Consumer resistors are
not adjacent to two auxiliary resistors and the bridge
resistor.  
Using the arrangement according to the invention, it is
possible to generate an alternating current of any frequency
and waveform from direct current.  
The direct current can be taken from any direct current
source, for example accumulators, carbon bag elements or
direct current generator machines can be used. By using
batteries, carbon bag elements, or other easily movable DC
power sources, AC power can be generated anywhere.  
The current strength obtained from the available direct
current sources.  
Alternating current is determined by the size of the
resistances arranged in the conductor parts of the closed
circuit and can be changed by adjusting the control
resistors. The frequency of the alternating current
generated is equal to the number of times the periodically
operating interrupter is switched on and off in a unit of
time.  
The periodically operating interrupter consists of a known
circular ring-shaped, self-contained resistor and a sliding
contact rotating on the resistance ring.  
One end of the conductor part containing the periodically
operating sub-breaker is connected to the sliding contact,
the other end to a point on the resistance ring. The
resistance of the interrupter is dimensioned in such a way
that when the highest resistance value is switched on, no
current flows in the conductor part containing the
interrupter, i.e. this conductor part is practically
interrupted: With one revolution of the sliding contact, the
current goes through a full period, so that the number of
revolutions of the sliding contact per second is equal to
the frequency of the alternating current generated.  
By appropriately designing the resistance ring, a wide
variety of curve shapes can be achieved; For example, a
sinusoidal alternating current or an alternating current
with a staircase-like curve shape can be achieved.  
In order to be able to achieve frequencies of any height,
the conductor part connected to the resistance ring is
connected in a manner known per se to any number of points
that divide the resistance ring into equal sections. In this
way it is achieved that when the sliding contact rotates, a
period number corresponding to the number of subdivisions is
created. For example, if the resistance ring is subdivided 6
times and the sliding contact rotates 100 times per second,
the frequency generated is 600 Hertz. An even higher
frequency can be achieved through a larger number of
subdivisions, which can be easily achieved by increasing the
size of the resistance ring.  
The switch adjacent to your bridge resistor and in series
with it is used to turn on or off.  
Disconnection of the direct current sources from the
circuit. When this switch is closed, a direct current flows.
Upon closure or When the periodically operating interrupter
is put into operation, the current directions are reversed
while the strength remains the same, so that an alternating
current is created. This alternating current flows in the
two conductor parts without switches in which the consumers
are arranged. In which with the input or A direct current
always flows through the conductor part provided with a
switch; while a chopped direct current flows in the
conductor part provided with the periodically operating
interrupter, so that it is possible to extract three
different types of current, namely pure direct current,
chopped direct current and pure alternating current, from
the arrangement according to the invention by arranging the
consumers at the appropriate points of the possibility of
drawing an alternating current with a superimposed direct
current component, through unequal dimensioning of the
auxiliary resistors including the bridge resistor: An
exemplary embodiment of the invention is shown schematically
in the drawing, and it means Fig. i circuit diagram of the
arrangement, Fig. a interrupter with one connection point,
Fig .3 Breaker with four connection points, Fig: q. up to 7
waveforms of the alternating current generated: According to
Fig. i, two direct current sources Ui and U2 are provided.
-The negative poles of the two power sources are connected
to one another by two series-connected auxiliary resistors
R1 and R5 and the consumer resistor Vi, which is also
connected in series.  
Likewise, the positive poles of the two current sources U1
and U2 are connected to one another by two auxiliary
resistors R2 and R4 connected in series and a consumer
resistor V2 also connected in series. The conductor part
between the adjacent auxiliary resistors R1 and RS (point B)
is connected to the conductor part between the adjacent
auxiliary resistors R2 and R4 (point C) via a bridge
resistor. R3 and an on/off switch S1 in connection.
Furthermore, a conductor connecting the positive pole (D) of
the current source U2 with the negative pole (A) of the
current source U1 is provided, in which a periodically
operating interrupter S2 is located.  
The auxiliary resistors R1; R2, R4, R5 and the bridge
resistance R3 are designed to be controllable.  
In order to generate a pure alternating current, all
resistors are dimensioned in such a way that one resistor
L'1 or L'2 corresponds to a load resistor. Tl, adjacent
auxiliary resistor R1 or R2 together with the relevant
consumer resistance V, or V2 has the same resistance value
as one of the other three resistors, namely the two
auxiliary resistors R4 and R5 and the bridge resistor R3.  
The switch S1 acts as a simple on or off.  
Off switch. As long as it is open, assuming the voltage of
the current sources U1 and U2 is the same, no current flows
in the arrangement. If you now first close the switch S1
with the switch S2 open, a direct current initially flows in
all branches of the arrangement, the strength and direction
of which are given by the voltage of the current sources Ui
and U2 and by all the resistances of the arrangement.  
If the switch S2 is now also closed, then, as calculation
and experiment show, a current flows in the branches in
which the consumer resistors TI and V2 are located, which is
the same and opposite to the current when the switch S2 is
open.  
If the switch S1 is kept permanently closed and the switch
S2 is periodically opened and closed, the sudden closing and
opening of the switch S2 and assuming induction and
capacitance-free switching results in an alternating current
with a rectangular curve shape (theoretical alternating
current)  
In practice,
a curve shape like that shown in Fig. q. arise.  
The current increases when S1 is closed according to the
current increase curve.  
When S2 is closed, the current drops almost vertically to
zero and then builds up again in the opposite direction to
the same strength.  
When S2 opens, the current drops almost vertically to zero
and then builds up again in the original direction. A single
opening and closing of S2 corresponds to one period of the
alternating current generated. The currents flowing through
the resistors RI-R5 are designated i, -i5.  
According to Fig. 2, the interrupter S2 consists of an
annular, closed resistor W.  
A contact lever K rotates over the resistor W.  
Point D is connected to lever K, while point A is connected
to connection point E of resistor W.  
If lever K touches point E, points A and D are directly
connected. If the lever continues to rotate, the resistance
between points A and D increases to its greatest value,
which is reached at points F. For example, if the resistance
W has 20,000 ohms, the maximum resistance between points A
and D is 2,000 ohms, so that the conductor part between
points A and D is practically interrupted. One revolution of
the lever K corresponds to one period.  
According to Fig. 3, point A is connected to points Ei, E2,
E3, E4 of resistor W, so that four connected resistors W1,
W2, Ws, W4 are formed.  
With one revolution of the lever K, the connection from A to
D is immediately closed four times at points Ei E4 and
interrupted four times at points F,-F4, so that four periods
result. For example, if the lever K rotates a hundred times
per second, a frequency of 4.0o Hertz is generated. The
resistance W according to Fig. 2 and the resistors Wl-W4
according to Fig. 3 can be designed as desired in terms of
their strength in individual sections, so that any curve
shape can be achieved, for example a pure sine curve
according to Fig. 5 or a step-shaped curve according to Fig
.6.  
If the resistance R3 is changed, the currents flowing in the
conductor parts between points A and B and C and D change in
strength, so that the amplitude of the alternating current
is changed.  
Abh.7 shows current curves with different amplitudes, namely
the curve with the amplitude GI corresponds to a small
resistance R3, the curve with the amplitude G2 corresponds
to a larger resistance R3 and the curve with the amplitude
G3 corresponds to an even larger resistance R3. By means of
the arrangement according to the invention, alternating
currents of a wide variety of frequencies and waveforms can
be generated. A direct current always flows in the conductor
part between points B and C both when the switch S2 is open
and when it is closed, while in the conductor part between
points A and D no current flows when S2 is open, but a
current flows in the direction from A when S2 is closed D
flows. A chopped direct current is generated in the
conductor part between points A and D. In addition to the
alternating current, direct current and chopped direct
current can also be taken from the arrangement at the same
time.

know if it will work but if I won't know if I don't try. Here are the first
pictures of my replication of the magnetstromapparat. The
setup is not finish and still a few things to do before
the tests start.  
Enjoy,

The Motionless Electricity Generator by Hans Coler****[ [PDF](MotionlessElectricityGenerator.pdf) ]****by
OVERUNITY ELECTRICITY**Hans Coler's generator has been revealed in a new
book, "Free Energy Conspiracy World." The book tells the
story of how Coler created a generator that could produce
free energy, and the government's efforts to cover it up.  
  
The generator is said to work by capturing energy from the
earth's magnetic field. Coler built several prototypes of
the generator, but never managed to perfect it. In spite
of this, he managed to keep the device secret for several
years.  
  
In 1937, Coler demonstrated his invention to a group of
scientists from Berlin University. However, they were not
able to replicate the results, and Coler was accused of
fraud. He was eventually forced to reveal how the device
worked, and his invention was seized by the government.

Energy of Electromagnetic waves in the Quantum-vacuum** **by Claus Wilhelm Turtur**

**[ [PDF](TurturColer.pdf) ]**

...As an example
for such a laymans work, we want to turn our attention
towards the exploration of Hans Coler, because today there
is report by intelligence service, which was made in the
second world war, and which was indexed for several
decades of years, but which is published in internet today
[Hur 40]. Based on this report we find also some
information in [Nie 83] and [Mie 84] nowadays. What we
know is, that Hans Coler (and his coworker Mr. von Unruh)
build two types of convertes, beginning in 1923, which
they called Stromerzeuger and Magnetstromapparat. Both
engines have an efficiency factor of more than 100%
(compared to classical energy-conversion). The
Stromerzeuger need some input-power, whereas the
Magnetstromapparat work completely wothout any energy
supply. Coler brought his engines to the Universities of
Berlin Munchen, Trondheim and Kopenhagen, where they have
been analyzed carefully. All the tests came to the result,
that Colers engines are really bringing more output-power
than they as input. These are serious confirmations of the
conversion of free-energy from some energy-sources unknown
up to now, but nobody understood the functioning principle
up to now. Colers terminology was not understood by
scientists, and so it is useless to try to repeat his
explanation here. Because the observations were not
understandable for all professionals and experts, they
ignored the Coler device completely. This is
understandable, because experts do not like to speak about
things which they do not comprehend. Unfortunately, the
scientific community forgot about the Coler device
completely. Thus the most authentic report existing today
is [Hur 40] as mentioned above. But when I tried to
reproduce the Magnetstromapparat, I was surprised, that
the [Hur 40] report has very small explanatory power. I
thought, a national secret service should have educated
staff to write documentations properly and understandable,
but I found that this is not the case with the report
about Hans Colers devices. Clear in any case is, that
Coler began with few Watts of power, but during the years
he learned to optimize his developments in way, that he
could gain even several kiloWatts later.  
   
Although the educated scientific community does not care
about Colers exploration any further, there are some
privat experimentators, who tried to rebuild Colers
devices. Besides  Hur 40] there is a description of
the Coler-devices in [Wik 09] (not explaning the
functioning principle in modern terminology). A trial of
reproduction of the Magnetstromapparat was made by
George Hathaway in 1981 and presented at the Canadian
First International Symposium on Non-Conventional Energy
Technology, giving a voltage of about 50 mV. Further
hints to other reproductions can be found at [Geo 10].  
Because of this uncertainty, I tried to reproduce the
Coler Magnetstromapparat (see Fig.33).  
  
**Trial of a reproduction of Colers Magnetstromapparat
in the work presented here.**After an extensive process of adjustment, which was
surprisingly not according to explanations of [Hur 40], a
machine power of approx. 25 milliWatt could be gained
reproducible.  
Also not in accordance with Colers original was the fact,
that an output was an alternating current (AC), because
Coler spoke about direct current (DC) power. By
Fourier-analysis we found a very wide band of frequencies
within the output-signal, but the local radio transmitters
could be found with a strong contribution to the
Fourier-spectrum. Thus it is not clear, how much energy is
coming simply out of classical radio-signal. Not typical
for complete energy supply by radio-signal is the fact,
that moving and turning the  
a radio-antenna. On the other hand, it was possible to
find a shielded room, in which the Magnetstromapparat did
not give any serious signal at all. But it would be
imaginable, that the shielded room also shields the
zero-point oscillations of the quantum-vacuum [Lie 10].  
For the results did not meet the results of Colers
original setup, a final analysis of all details was not
executed. On this background, I can not answer the
question about the functioning principle of the
Coler-setup now. I cancelled my analysis of the
Coler-converter, after I got a confirmation of the
ambiguity from a colleague, who also tried to reproduce
the Coler-converter. He additionally explained me his
findings, that our guidline in [Hur 40] is incomeplete. It
is known, that intelligence service did not publish the
report completely. This also explains the lack of
informative value in the publication by [Hur 40].
Obviously they had had trained and educated staff to make
the report, but not the complete report is free from being
indexed still today.  
Thus the resumee is that Colers findings are still
explosive enough 90 years after discovery, that they are
still partially indexed nowadays. This emphasizes
theveritableness of his work and the importance to
reproduce it in an appropriate way, filling up the missing
parts in the available report. Therefore it looks
worthwhile to understand the theory behind the device 
this seems to be the only way to filling up the missing
knowledge.

[**https://www.overunityresearch.com/index.php?topic=3844.0**](https://www.overunityresearch.com/index.php?topic=3844.0)  
As I am getting on in years now (I'm 85) it is time to put
out some of the stuff I have accumulated on my computer
hard drive.  While working for Chava I did some
research into the Unruh/Coler story that led me to the UK
National Archives.  Up to that time the internet
buzzed with the declassified British Intelligence
Objectives Subcommittee (BIOS) Final Report No.1043 which
was the only source for the Unruh/Coler devices.  The
National Archives provided more data that has since then
leaked out to the internet.  Just to put the story
straight below is my original paper written in 2009 with
the results of my research.  That work showed the
Stromerzeuger to be based on the Norrby invention whereas
before then there was much speculation as to the exact
architecture of the device.  I still have images of
all the pages in the National Archives, there are about
188 jpeg images each about 4Mb.  I recall someone
(possibly Bob Flower) creating a pdf file of this string
but I don't have a copy of that.  
  
Having a much clearer idea of the Stromerzeuger has led me
to various speculations of how the device worked and these
will be posted on this thread.  One such is already
seen in the "Corbino Effects and Coler" thread here
https://www.overunityresearch.com/index.php?topic=3377.0. 
That work seems to have died.  Perhaps my ramblings
will encourage other people to experiment.  I realize
that the Magnetstromapparat anomalous output is now
considered by some to be due to the early use of silk
covered copper wire which wound around an electrically
conductive PM would in a damp atmosphere create a battery
effect.  I don't think this applies to the
Stromerzeuger as the work on that spanned several decades
and we later find Coler using enameled copper
wire.   The Stromerzeuger uses soft iron cores
where conduction electrons (at a density of about one per
atom) can become spin-polarized, and that opens the door
to many possible schemes for extracting energy from the
inner quantum world that holds atoms together and keeps
atomic electrons spinning and orbiting.  
  
The first paper here was written in 2005 before the
National Archive data was available and shows my
(incorrect) attempt at describing the Stromerzeuger
layout.  I also suggest the possibility that energy
can be gained from the microwave Larmor precessions of
atomic electrons working as charge pumps, pumping
traveling conduction electrons that follow helical paths
due to Cyclotron effects.  Because the Larmor
frequency and the Cyclotron frequency have a common cause
and are phase locked, this creates a rectification effect
pumping the conduction electrons in one preferential
direction.  To my knowledge this idea has never been
explored.  
  
The second paper (written in 2009 but only recently
converted to pdf) is the result of my National Archives
research where I discovered that Coler was given a
contract to work in the UK to replicate the Stromerzeuger,
but unfortunately he had a heart attack and died before he
could claim success.  
Smudge    
**Ideas about the Coler Device [ [PDF](IdeasColer.pdf) ]**Well, the initial results were not conclusive by any
means due to several factors.  First, the iron toroid
with the few turns I applied had a measured inductance of
6uH which required a large magnetizing current even at
180kHz.  Also, the primary had too many turns
resulting in too little input current at 100-180kHz.   
  
So, I'll rewind the coils and try again.  I've
attached a pix of the transformer below and the toroid was
cut from an iron pipe and shaped.  The ferrite "E"
core has the same area for all legs.  
Pm   
  
[**https://www.overunityresearch.com/index.php?topic=3377.0**](https://www.overunityresearch.com/index.php?topic=3377.0)**Corbino Effects and Coler**There has been little attention paid to Hans Coler's
(really Unruh's) inventions in this forum.  My work
with Chava produced more background showing that his
Stromerzeuger was based around the Norrby device as
suggested by Fred Epps who posts here as Orthofield. 
While there are those over at OU.com who think that it was
all a fake I am still of the opinion that the S machine
has some merit.  I have looked into variations of the
Hall/Corbino effect taking it into a cylindrical form
where the possibility exists that induced RF eddy currents
flowing around the ferromagnetic cylinder flow only in a
thin surface layer (skin effect) and if that surface layer
has some static radial magnetization the Anomalous Hall
Effect (AHE) will induce longitudinal voltage to drive
surface current along the cylinder.  
  
That there exists the possibility of some self oscillation
is not new, D.A. Kleinman and A.L.Schawlow predicted just
that possibility back in 1960, see Corbino Disk abstract
below.  In fact they filed a patent assigned to Bell
Telephone Labs, US patent 3089995, copy also attached
here.  While that required cryogenics to get the low
temperatures it demonstrates a solid-state self
oscillating thingammyjig having no power source (although
the patent didn't claim that, it just claimed negative
resistance).  Since that date there has been more
knowledge of the AHE in ferromagnetic material and I think
it possible this could explain the working of the
Stromerzeuger at room temperature.  More later.  
Smudge   
  
 Here is a paper I wrote a while back explaining the
Corbino Effect where radial current in the disc creates
additional circular current via the Hall Effect, the net
current flow then being a spiral.  There are no
practical machines using the effect so it is little known
among engineers and experimenters.  The Inverse
Corbino Effect (my name for the effect) induces circular
RF current (eddy currents) so as to produce a radial
electric field that can drive radial current into a load,
which of course is RF.  I have never seen this
described anywhere.  Then there is what I call the
Cylindrical Corbino Effect where a thin walled cylinder is
used instead of a thin disc.  A radial magnetic field
through the cylinder wall then allows a longitudinal
current to create an additional circular current via the
Hall Effect, the net current flow then being spiral. 
Finally the Inverse Cylindrical Corbino Effect uses that
same thin walled cylinder, having circular eddy currents
induced into it that then produce RF voltage across the
ends of the cylinder.  This is all illustrated in the
paper.  I have never seen these cylindrical
possibilities described anywhere.  Of note is the
fact that for a Fe rod RF currents will only flow in the
outer skin (skin effect) so the thing will act like a thin
walled cylinder.  And Coler's magnetized piano wire
at one end of his rod would produce the necessary radial
magnetic field, perhaps enhanced by his multiple coil
arrangement.  If the coil driving the eddy currents
is put in series with the rod and a capacitor then you
have a tuned circuit that could possibly self oscillate if
the induced Hall voltage along the rod is sufficiently
high.  Something to think about there.  
Smudge  
  
**The Inverse Corbino Effect applied to the
Stromerzeuger.pdf**  
OK i hooked up my pure iron rod and wound a coil down it's
length and hooked it up to my switchable cap bank and
adjusted the cap value for max amplitude, i used my scopes
internal DDS to lock at 180KHz to drive the coil and
parallel cap bank.  
  
One end of the iron rod had the coil connected to it and
the other end had a neo magnet with a wire sandwiched
between the magnet and iron rod, i marked one side of the
magnet so i knew which way round it was and then scoped
the sine with the magnet each way round.  
The DDS is only 2.5V Amplitude or 5V pk-pk.  
  
There is a small measurable difference when the magnet is
flipped, see both scope shots, each scope shot is with the
magnet in different orientations.  
  
One way the average pk-pk is 329mv  
the other way the average pk-pk is 322mv  
  
I tried a few times to make sure it was not the sandwiched
wire disturbance that was causing this and the results
were the same each time.  
So i think we have a very small confirmation of the effect
here  
  
any tips on how to progress would be helpful  
  
PS i did not know if the iron rod polarity matters, in the
picture below, the black wire is sandwiched between the
magnet and iron rod, this is one connection that goes to
my cap, and the blue wire coming from the coil end near
the magnet is the other connection to the cap, the left
hand side of the rod and coil are connected together.  
  
Peter,  
If I read you correctly you have the Fe rod in series with
the coil and are looking for a change of Q when the magnet
is reversed.  You could try putting another magnet on
the other end of the rod.  Its polarity must be
reversed to that of the first magnet so that both magnets
push flux inwards (or outwards).  This then increases
the amount of flux coming out radially.   The
effect should then be slightly increased on the 7mV
difference that you saw.  That should help confirm
that what you measured really was this Hall/Corbino
effect.  
  
Another possibility is to not have the rod in series with
the coil but drive the parallel coil/cap as you did. 
Then scope across the Fe rod which should be almost a
short circuit but may have a small measurable
voltage.  If it is detectable look to see if its
phase changes by 180 degrees when the magnet is flipped.  
Smudge   
  
 OK i just did the magnet part of the test, first i
want to check with you, i am connecting my signal
generator across the LC i am not loose coupling is that
OK, if not i will re do the experiments.  
  
So the tests below.  
One magnet scope shot 1  
2 magnets attracting, 1 each end scope shot 2  
2 magnets opposing 1 each end scope shot 3  
1 magnet flipped so opposite face is on iron rod scope
shot 4  
2 magnets attracting scope shot 5  
2 magnets opposing scope shot 6  
  
then i switched the end of the coil that was in series
with the iron rod.  
1 magnet scope shot 7  
2 magnets attracting scope shot 8  
2 magnets opposing scope shot 9  
  
Strange results?  
1=320mv 1 magnet  
2=324mv 2 magnets Attracting  
3=316mv 2 magnets opposing  
4=314mv 1 magnet other way around  
5=306mv 2 magnets attracting  
6=318mv 2 magnets opposing  
7=334mv 1 magnet with other end of solenoid in series with
iron so as test 4 but with the different solenoid end in
series with the iron  
8=316mv 2 magnets attracting with solenoid wire the same
as 7  
9=320mv 2 magnets opposing with solenoid wire the same as
7  
  
I have to say even though the magnets are opposing they
still stick to the iron rod with force at both ends  
It would be interesting to try a  setup by having two
identical coils and iron rods, both initially without
magnets and subtracted using Ch1 minus Ch2 of your scope.
Then as you apply the magnet

--  ENHANCED TRANSFORMER****BACKGROUND OF THE INVENTION**  
Since Faraday, we know that the motion of magnetic flux
may be used to generate electric energy. It is not well
known that attempts at electrical power generation without
physical material motion (non-motional) have been achieved
with limited efficaciousness. These endeavors utilize
electromotive force to control magnamotive force
universally, effectually non-motional thus depending on
the relative motion of a changing flux density. All of
these attempts have failed to pay adequate attention to
the hostile environment thereby created and the resulting
hysteresis losses have eventually induced degradation of
the permanant magnets (P-M) . The fundamental principles
and history of electrical generation in the solid state
format using permanent magnets begins with Hans Coler's
"Stromerzeuger" & "Magnetstromapparat" research in
Germany 1936-1945, but, is illustrated and best summarized
with the prior art cited here..
