    "publication_year": 1929,
    "device_name": "Amplificateur de courants A(c)lectriques / New Electric Generator",
    "goal": "To harvest ambient electromagnetic energy and generate electrical power without the use of traditional chemical batteries, achieving higher voltage and current than the input source.",
    "problem_addressed": "Dependence on costly, hazardous chemical batteries and limited energy density of conventional generators; need for a low-cost, portable power source.",
    "concept_summary": "The invention combines a modified Ruhmkorff coil with a large-section secondary winding and a simple electro-chemical cell (copper, carbon powder, water, zinc) to capture ambient electromagnetic fields and amplify the induced current. By varying PWM parameters (amplitude, frequency, duty cycle) the device claims to produce over-unity power, delivering several hundred watts from a low-voltage battery or ambient EM energy.",
    "detailed_description": "Two patents are described. FR667647A (1929) presents an induction machine where a primary coil (50 turns) drives a secondary coil (1000 turns) wound with thick wire; the secondary's cross-section is claimed to increase current capture, and PWM modulation is used to optimise the coefficient of performance. Experimental videos claim over-unity from a step-up transformer. FR633752A describes a battery-type generator replacing the classic copper-acid-zinc chain with copper-water-zinc, using carbon-powder bags soaked in water as the positive electrode. The device allegedly delivers high voltage (up to 660 V) and sufficient current to run a 10 HP motor for 30 h after a short re-soak, with low internal resistance and no hazardous chemicals.",
