**Robert W. Bussard**

Robert W. Bussard is an American physicist working primarily in
nuclear fusion energy research.

In 1960, Bussard famously conceived the Bussard ramjet, an
interstellar space drive powered by hydrogen fusion using
hydrogen collected using a magnetic field from the interstellar
gas. Due to the presence of high-energy particles throughout
space, most interstellar hydrogen exists in an ionized state
that can be manipulated by magnetic or electric fields. Bussard
proposed using a large magnet to "scoop" up the ionized hydrogen
and funnel it into a fusion reactor, using the exhaust from the
reactor as a rocket engine. Since it picked up its fuel from
space, there was no apparent upper limit to the speed such a
craft could achieve. However it appears the "energy gain" in the
reactor must be extremely high for the ramjet to work at all;
any hydrogen picked up by the scoop must be sped up to the same
speed as the ship in order to provide thrust, and the energy
required to do so increases with the ship's speed.

In the early 1970s, Bussard joined the director of the, then,
Atomic Energy Commission's Controlled Thermonuclear Reaction
Division, Robert Hirsch, as Assistant Director. They founded the
mainline fusion program for the United States: the Tokamak.
Later, Bussard in a June 6, 1995 letter to all fusion
laboratories as well as to key members of US Congress regarding
his role in the founding of the US fusion program, claimed that
he, along with the other founders of that that program,
supported the Tokamak not out of conviction that it was the best
technical approach but rather that it would provide a vehicle
via which political support for fusion development could be
generated, thereby allowing them to pursue "all the hopeful new
things the mainline labs would not try".[1]

With fellow researcher Bruno Coppi, Bussard later founded
Inesco, a private firm funded in part by Penthouse Magazine
publisher Bob Guccione. Inesco set out to build small
power-producing Tokamak fusion reactors called Riggatrons using
methods developed from the MIT Alcator research tokamaks. The
method they were trying to use in order to initiate fusion
proved vastly more difficult to achieve than they had
anticipated and Inesco eventually shut down when its funds ran
out.

Bussard later founded another company, Energy Matter Conversion
Corporation (EMC2), which has engaged in research on variants of
the Farnsworth-Hirsch fusor. In an article entitled "The World's
Simplest Fusion Reactor: How To Make It Work" in the December
12, 1998 issue of Analog magazine, fusion researcher Tom Ligon
described an easily-built demonstration fusor system, and some
of Bussard's ideas for fusion reactors and incredibly efficient
spacecraft propulsion systems, which could enable single-stage
spacecraft to travel anywhere in the Solar System in short times
compared to chemical rockets.

On March 29, 2006, Bussard claimed on the fusor.net forum that
EMC2 had developed an inertial electrostatic confinement fusion
process that was 100,000 times more efficient than previous
designs. However, the company's funding ran out, and Bussard is
looking for additional funding to develop a full-scale fusion
power plant. On June 23, 2006 Bussard provided more details of
the breakthrough and the circumstances of the shutdown of this
work by the government.

Dear Sir Philip:

I have read the threads on the Randi forum, and they are all
intent and I am sure well-menaing. However, I have not been able
to "log in" on this forum so am writing to you instead. Perhaps
you can post this note as a reply and commentary to some of the
issues raised by your forum correspondents.

First, what we have achieved in our rather unexpectedly good
tests of last November 9 and 10th was an output of DD fusion at
about 10 kV, at B fields of 1300 G, in a 30 cm diam device
(WB-6) run in a pulsed mode from big capacitors, with a fusion
rate of about 1E9 /sec. This works out to be about 100,000 x
higher than the data of Hirsch/Farnsworth at similar well depth
and drive conditions. The test duration was only about 0.4
masec, but since the electron lifetime is ca 0.1 microsec this
is steady-state to the plasma particles. We had neither the
money, nor the cooling, nor the power supplies, nor the controls
to run this small device steady-state, which is what we need to
do, and what requires us to build the full-scale device.

This was a direct result of discovering something during late
Spring/ early summer tests of WB-5, which was a closed boc
machine, like the early HEPS of 1989. What we discovered was --
in hindsight -- elementary; it was that indeed God is in the
details, and the detail of particular importance is that no
metal surface penetrated by B fields must occupy more than about
1E-4 to 1E-5 of the total surface available to the recirculating
electrons. If this dead fraction is larger, there is NO hope of
net power from any such machine. AND, it is essential that the
device be recirculating, i.e. that the electrons can circulate
out and back through the cusps all over the machine. Of course,
this is obvious; but in 15 years no one saw it, not Hirsch, not
our consultants not our opponents, not our staff, and not me.

It is consistent with the need for electrons to recirculate
about 100,000 times before being lost to collisions with
structure, to yield net power.

Please remember that our device has the property that the
electron flow and losses are decoupled from the ion flow and
fusion generation. Power balance depends on suppresssion of the
electron losses, which are derived from the energetic electron
injection that forms the gridless negative potential well that
traps the ions.

When we figured this thing out, in summer 2005, we quickly
designed and quickly built WB-6, using only conformal (with the
B fields produced) coil cans, so that no B field uniquely
penetrated the cans, and then placed the coils in a special
array so that no corners touched (this latter is a long topic
having to do with local B fields, and loss of WiffleBall
trapping due to line cusp effects at the corners, etc, etc, and
is the baisis of our final patents on this thing). It IS the
details that make or break the device. And this particular set
of details absolutely dominates the performance.

Anyway, we ran the device in October, for beta=one tests, to
confirm transport scaling laws, and then in early November to
test for fusion output. And, happiness, indeed, three tests on 9
November and one on 10 Novem,ber gave the results mentioned
above. The next day, 11 November, we tried it again, but magnet
coil motions induced by repeated testing had moved the coils
enough that an insulation spot had worn away inside the cans,
and the device shorted and blew up one leg, with the full cap
discharge. Having no further funding, we had to start shutting
doen the lab the following Monday!!! Irony?

As to our funding -- our USN contract still exists, and still
has about $ 2M authorized in it. However, year-by-year funding
was NOT provide for FY 2006, so that we knew we had to close
down early in 2006.. What saved us was Adm Cohen (CNR) who put
another 900 K into the program to try to get us down the road to
where we DID go, and then we had to quit. It was not a cutoff of
OUR funding, but the entire Navy Energy Program was cut to zero
in FY 2006, and we were a part of this cut. The funds were
clearly needed for the more important War in Iraq.

So, as we cut down, we managed to save the lab equipment, by
transfer to SpaceDev, which hired our three best lab people as
well, and we are still trying to get the missing $ 2M restored
and put into our existing but unfunded contract. IF this happens
- which is improhable, given the politics of this election year,
and the non-visionary people in Congress - we will redo WB-6
with an improved and better version (WB-7) which should give 5x
more output, and run about 50 tests to quiet dissent. AND we
will convene a review panel of very high-level and
internationally distinguished people to spend about 6 weeks
going over this to recommend for or against proceeding sith a
full scale demo.

This may or may not happen. If it does, I have little doubt as
to the panel recommendation, as the data and insight from WB-5/6
is just too clear. We really have solved the last engineering
physics problem that has plagued our work for 12 year s or so.
Yes, there is much left to do, iespecially in controls and
diagnostics, but these are predictable things not dependent on
beating the Paschen curve.

And we still have to develop some reliable e-guns and
i-sources, again predictable enginering that costs both time and
money, but not new physics.

Why a full-scale demo? Because the system scales oddly: Fusion
output goes as the 7th power of the size and Gain goes as the
5th power. Thus there is very little to be gained by building a
half-size model; it is too weak to give anything definitive
about power production or gain. And our tests were always at
about 1/8 to 1/10 scale of the full scale demo. We told the DoD
from the beginning that the real program would cost about
150-200 M, since 1987, and they all knew this. However, since
the DoD has no charter to do such work, and the political
realities were that a big DoD program would attract the ire and
power of the DoE to kill it, it was never funded beyond about
1/8 the level required.

So we did what we could and finally DID prove the physics and
associated engineering physics constraints, scaling laws, etc,
albeit at 1/8-1/10 scale. So what? Doubling the size will not
tell us anything we don't already know. The next intelligent and
logical step is to build a machine big enough to make net power.
And THAT is the same 200 M we have quoted to the DoD since the
beginning.

As for energy companies "stampeding" to support us -- It is
clear that a view like this is ignorant of the reality of energy
companies. There is only one thing the oil cvompanies want, and
that is to sell oil, and more oil. So long as the fields pump,
the oil companies will squeeze. They have NO, absolutely NO
interest in anything new, ins spite of all their foolish ads in
magazines for wind mills and solar-PV roofs. It is all just show
and tell. I know these guys, and there is no way they would
support anything that might get in the way of oil. The only way
to stop oil, from their view, is when it does run out. And then
they''ll go for deeper drilling, new fields, Gulf geopressure
gas, LNG, etc, etc, and keep raising the price, until finally
foolish solar and windmills become competitive.

And we are paying the equivalent of $ 500/bbl oil costs. But
Exxon and Halliburton are getting richer all the time.

Yes, we would like to build the demo plant, and yes, it will
cost about 150 (DD) to 200 M (pB11), and who knows if any
investor singly or a group can or will come up with the money.
One of the biggest obstacle is the world-wide tokamak lobby,
which perpetuates the fraud that Hirsch, Trivelpiece and I
foisted on the country in the 1970's when we started the big
tokamak ball rolling.

Magnetic confinement fusion is a misnomer, as magnetic fields
can NOT confine a plasma, only constrain its motion towards
walls. The entire history of the MagConf program has been to
reduce transport to neo-classical (not turbulent or
instability-driven) losses. And THEN the machines are all
inherently and inevitably huge and cost too much and make too
much power to ever be economically useful --- as the utilities
have been telling the AEC/DoE for 30 years. No matter, the
global tokamak program provides jobs for hudreds of thousands of
people in many countries, and is a safe place to put political
pork funding, simply because it IS NO THREAT TO OIL - it won't
ever work, but it sounds good to the untutored public..

As for us; our company still exists, but we will not likely run
any demo program - that will be up to others to carry it on, if
we all get the chance. Meanwhile, my objective is very simple. I
detest the energy stranglehold of our companies on our people,
and am going to try to give our idea away at the soonest
possible moment. To anyone, anywhere, who might want to
undertake its development. And we'll be happy to help in any way
we can, if a serious interest develops anywhere in the world.

I think the US, UK, France, et al are lost causes, because of
theri commitment to the failed tokamak effort, as is probably
Germany, and maybe others, too. China may be a possibility, as
it is quite independent even though part of the ITER mess,
Russia may be considererd, and countries like Spain, Brazil,
Italy, Argentina, and others may logically have an interest.

I believe that the survival of our high-tech civilizations
depends on getting off of fossile fuels ASAP, and - if we do not
- we will descend into a growing series of "oil wars" and energy
confrontations that can lead only to a huge cataclysim. Which
CAN be circumvented if only we build the clean fuison machines
in time. Our patents are in final form, and I am giving a paper
in the Fall, and trying to get a large technical description
together for a major paper by summer. We shall see.

One final word: Actually our device is really not a variant of
Farnwworth/Hirsch, but of Elmore/Tuck/Watson who propeosed the
inversion of Farnsworth/Hirsch long ago (ca. 1967). Their
problem was the interception of circulating electrons by grids -
we removed the grids and replaced them by B field insulated
coils - thus our "grids" are the coils themselves.. And we do
know how these work, at last.

Good luck to all of us.

Cheers, RW Bussard

**Should Google Go Nuclear?**

Baldrson writes "One of the founders of the US Tokamak fusion
program, Dr. Robert W. Bussard, gave a lecture at Google
recently now appearing as a Google video titled 'Should Google
Go Nuclear?'. In it, he presents his recent breakthrough
electrostatic confinement fusion device which, he claims,
produced several orders of magnitude higher fusion power than
earlier electrostatic confinement devices. According to Bussard,
it did so repeatably during several runs until it blew up due to
mechanical stress degradation. He's looking for $200M funding,
the first million or so of which goes to rebuilding a more
robust demonstrator within the first year. He claims the scaling
laws are so favorable that the initial full scale reactor would
burn boron-11  the cleanest fusion reaction otherwise
unattainable. He has some fairly disturbing things to say in
this video, as well as elsewhere, about the US fusion program
which he co-founded."

**"Should Google Go Nuclear? Clean,
cheap, nuclear power (no, really)"**

ABSTRACT --- This is not your father's fusion reactor! Forget
everything you know about conventional  ... all thinking on
nuclear fusion: high-temperature plasmas, steam turbines,
neutron radiation and even nuclear waste are a thing of the
past. Goodbye thermonuclear fusion; hello inertial electrostatic
confinement fusion (IEC), an old idea that's been made new.
While the international community debates the fate of the
politically-turmoiled $12 billion ITER (an experimental
thermonuclear reactor), simple IEC reactors are being built as
high-school science fair projects.

Dr. Robert Bussard, former Asst. Director of the Atomic Energy
Commission and founder of Energy Matter Conversion Corporation
(EMC2), has spent 17 years perfecting IEC, a fusion process that
converts hydrogen and boron directly into electricity producing
helium as the only waste product. Most of this work was funded
by the Department of Defense, the details of which have been
under seal... until now.

Dr. Bussard will discuss his recent results and details of this
potentially world-altering technology, whose conception dates
back as far as 1924, and even includes a reactor design by Philo
T. Farnsworth (inventor of the scanning television).

Can a 100 MW fusion reactor be built for less than Google's
annual electricity bill? Come see what's possible when you think
outside the thermonuclear box and ignore the herd.

**Abstract** -- An apparatus and method of enhancing
nuclear fusion reactions utilizes a plasma, made up of ions and
electrons, contained within a region, and enhances the density
of the plasma using a collision-diffusion compressional
enchantment process. Ion acoustic wave generated within a
central region of the system permits increased reflection and
scattering of ions and thereby reduces their mean free path
within the core region to permit greatly increased ions density
sufficient to enhance nuclear fusion reactions within the core.

**Abstract** -- A fusion power generating device is
disclosed having a relatively small and inexpensive core region
which may be contained within an energy absorbing blanket
region. The fusion power core region contains apparatus of the
toroidal type for confining a high density plasma. The fusion
power core is removable from the blanket region and may be
disposed and/or recycled for subsequent use within the same
blanket region. Thermonuclear ignition of the plasma is obtained
by feeding neutral fusible gas into the plasma in a controlled
manner such that charged particle heating produced by the fusion
reaction is utilized to boot-strap the device to a region of
high temperatures and high densitities wherein charged particle
heating is sufficient to overcome radiation and thermal
conductivity losses. The high density plasma produces a large
radiation and particle flux on the first wall of the plasma core
region thereby necessitating replacement of the core from the
blanket region from time to time. A series of potentially
disposable and replaceable central core regions are disclosed
for a large-scale economical electrical power generating plant.

**Inertial Electrostatic Fusion systems can
now be built**

by

**Robert W. Bussard**

Our company, EMC2, has been working since 1987 on the R&D
of Iour polyhedral IEF concept for fusion; mostly under DoD
support. Final tests were made last Oct/Nov on a unique new
design, based on unexpected discoveries made in Spring/Summer
2005. This final machine, WB-6, showed 10x lower e- losses than
any predecessor and produced DD fusions at a rate over 100,000x
times higher than the data of Farnsworth-Hirsch in the 1960's
for same drive conditions.

We have now proven the engineering and physics scaling laws
that allow design of full-scale net-power systems, whether on DD
or pB11. USNavy budget line item that supported our work was
zero-funded in FY2006, and our lab had to shut down and close
one week after achieving these results! We are probably the only
people on the planet who know how to make a real net power clean
fusion system, and we are out of support! Somewhat ironical!

The next logical step MUST be a full-scale net-power demo
system, simply because there is not much left to do at small
scale; when it is realized that the fusion output of these
devices scales as the 7th power of the size, and the gain scales
as the 5th power.

These outlandish scalings (inherent in the engineering physics
of the thing) make it useless to build half-scale systems (for
example). Unless you are AT the net-power size, you are nowhere
in power and gain, even though the physics IS relevant. We have
always been limited to about 0.1 scale, and have learned nearly
all there is to know about the system's basic operation.

Thus, we have the ability to do away with oil (and other fossil
fuels) but it will take 4-6 years and ca. 100-200 M$ to build
the full-scale plant and demonstrate it. Anyone care?

**Inertial Electrostatic Confinement Reactor
based Fusion Ash Impact Propulsion System**

**by**

**S. Krupakar Murali**

**( Fusion Technology Institute, University of Wisconsin,
Madison -- 1500 Engineering Dr., Madison, WI 53706 )**

**Abstract** --- A new Inertial Electrostatic Confinement
reactor (IEC) based Fusion Ash Impact Propulsion (FAIP) unit
devoid of magnetic fields is proposed in this paper. 
Theoretically, this system yields extremely high specific
impulse ~ 5.5 x 106s, higher than any other advanced propulsion
concepts available at this time.  Besides, a very high
specific power 100 kW/kg, and a relatively high thrust-to-weight
ratio of ~0.031 can be obtained. The present design produces a
continuous thrust of ~0.9N over the entire duration of the
journey. FAIP system can be used to propel spaceships during
interstellar missions such as mission to Heliopause, which is at
a distance of around 120 to 150 A.U. in a period of 
~30yrs.  The concept is also suitable for missions beyond
Heliopause, since calculations show that the FAIP system does
not burn all its fuel when it reaches Heliopause,(at the end of
the mission this system would have consumed only 3.55 kg of its
fuel.  Hence if the system continues its trajectory much
higher terminal velocities (depending on the mission time) could
be achieved eventually, leading to the accomplishment of even
longer-range missions.

The double gridded IEC device can be used to realize extremely
high ion densities in the core region of the inner grid, which
in turn results in an extremely high fusion power density
there.  Recent experiments at University of Wisconsin,
Madison (U.W. Madison) have demonstrated the feasibility of
using advanced fusion fuel D  3He for steady state operation of
the device e.g., producing ~3 x107 (14.7MeV) protons/sec steady
state.  Research group at U.W. Madison, are the first to
realize D  3He reactions on a steady state basis.

*THE TECHNOLOGY*

Dr. Bussard and his team at Energy/Matter Conversion
Corporation, after close to 20 years of hard work, have
developed a revolutionary radiation-free fusion process that
could change the world as we know it today.

Fusion is the energy that powers everything in the universe.
The sun's energy comes from fusion. Alternatively, fission is
the process whereby heavy atoms, which are nearly unstable, are
split into two radioactive atoms. Fusion, on the other hand, is
when two light atoms merge.

The ultimate fuels for fusion include hydrogen and other light
atoms such as lithium, boron, and helium isotopes. Some of these
reactions are radiation free, others are not.

The fusion process recommended by Dr. Bussard takes boron-11
and fuses a proton to it, producing, in its excited state, a
carbon-12 atom. This excited carbon-12 atom decays to
beryllium-8 and helium-4. Beryllium-8 very quickly (in 10-13 s)
decays into two more helium-4 atoms. This is the only
nuclear-energy releasing process in the whole world that
releases fusion energy and three helium atoms -- and no
neutrons. This reaction is completely radiation free.

The most commonly studied fusion process today is the reaction
that occurs between deuterium and tritium, the so-called DT
reaction, that produces helium and a radioactive neutron.
Various magnetic confinement vessels have been designed and
developed over the years to contain the high-energy DT fusion
reaction. The Tokamak is one such magnetic confinement vessel,
30 m across by 110 feet tall.

The majority of fusion processes being investigated today are
very expensive, costing billions of U.S. dollars; require giant
machines; and offer no predictability. Nonetheless, we know that
fusion works because every star is a fusion reactor. The fusion
reactors of the stars and the sun are held together by a direct
force field. This works very well and efficiently -- this force
field is gravity.

Gravitational forces between particles draw them directly
together. Only one other force is known to be like gravity: this
is the electric field force or "coulomb" force, between
electrically-charged particles.

Charged particles of opposite signs attract each other with
direct forces; charged particles in electric fields feel forces
directly along field gradients. Thus, fusion fuel plasmas could
be held together efficiently by electric forces and electric
fields. This is called "Electric Fusion".

Dr. Bussard was not the first to try to create such a field.
One notable technique utilized a spherical screen grid that was
biased to a positive potential, thereby attracting electrons
through the screen, producing a negative potential well. As the
electrons passed through the screen, they slowed down as their
kinetic energy was transformed into potential energy in the
potential well, and ions could then be dropped into it at the
edge, fall down, and be recirculated back and forth. Any
particles not reacting went back into the well. The only problem
with this method was that the grid was not transparent. Because
of the high interception rate on the grid, essentially all of
the energy put into the electron acceleration went into the
grid. Energy was lost and the grid melted. This technique just
didn't work.

Dr. Bussard's invention, however, removes the fore-mentioned
grid and replaces it with a magnetic field. It is known that
magnetic fields do not contain neutral plasmas very well (as
illustrated in the case of the Tokamak). Magnetic fields,
however, contain electrons very easily because electrons are
extremely light.

The basic approach of electric fusion is the following:

Quasi-spherical magnetic fields trap injected energetic
electrons to form spherical negative potential well.   
Fusion ions trapped in this spherical well focused through
central region oscillate across the "core" until they are
reacted.   
The system acts like a spherical colliding beam device.   
Fuel gas is input at the potential well edge. Fusion products
escape to system walls.   
Ion fusion power generation occurs in a central region.   
Electron drive power is decoupled from the fusion process.   
Power balance is set by injected electron losses; the main
losses occurring through the magnetic cusps and to walls.   
Magnetic confinement of electrons is critical.   
"Wiffle Ball" (WB) effect insures cusp sealing.   
Magnetic insulation of the walls is important.   
"Magrid" (MG) effect reduces power and raises gain.

In 1994, Dr. Bussard successfully demonstrated a wiffle ball,
achieving a beta-1 condition. In 2005, he was able to
magnetically insulate the electrons from the walls via his
"Magrid" transporter.

Early prototypes experienced some losses because the original
coils touched one another, resulting in intersecting magnetic
fields. This made the magnetic field lines run into the metal
vessel walls resulting in electron losses. Dr. Bussard realized
that all the coil containers had to be conformal to the magnetic
fields they produced. If he utilized circular torroidal coils
spaced at the corners, the magnetic fields could be allowed to
go out between the coils. Using such a device, that offered both
the wiffle ball effect and the magrid transporter, Dr. Bussard
was able to achieve 1x109 fusions/second for .25 milliseconds.

In summary, Dr. Bussard's Inertial Electrostatic Fusion offers

Small, efficient power reactors, 1-3% the size of current
magnetic confinement reactors.   
Clean, radiation-free energy utilizing p B-11.   
Relatively simple engineering with commercial viability in 6-10
years.   
Low cost ($150-200 million from program inception to
demonstration of clean power.)
