Free-Energy Claims Database
Explore recurring claim types from Keely through Rossi and compare each claim with the investigation or evidence gap that matters.
Filter locally. Source links document claims or evidence gaps; they do not imply endorsement.
Key facts
- The database indexes recurring claim patterns and source trails, not a complete history of every device.
- Patent links document what was claimed; they are not treated as independent performance proof.
- Evidence status is framed around boundary accounting, measurement quality, and independent replication.
10 claim patterns
10 records match the current filters.
| Claim | Era | Category | Status | Outcome and evidence issue | Source |
|---|---|---|---|---|---|
| Keely Motor | 1870s-1890s | vibration / hidden power | Historical failure | No independently verified motor emerged; later investigation centered on concealed apparatus and ordinary power explanations.No open, replicated input-output test; claimed force was never made inspectable. | Keely Motor archive |
| Howard Johnson permanent magnet motor | 1970s-1980s | magnet motor | Patent claim, not demonstrated energy source | The patent documents a permanent-magnet motor claim; public evidence has not established a replicated net-energy generator.Magnetic reset work and load testing are the central missing controls. | US4151431A patent record |
| Joseph Newman's energy machine | 1979-1986 | electromagnetic motor | Tested negative by NBS | National Bureau of Standards testing for the patent dispute did not find output energy greater than input energy.Electrical measurements and battery input did not support over-unity performance. | NIST / NBS report |
| Stanley Meyer water-fuel cell | 1980s-1990s | water fuel / electrolysis | Patent and demonstration claims | Patent records document the asserted gas-production method, but hydrogen-from-water still needs complete electrical and chemical energy accounting.Electrolyzer input, gas composition, flow, pressure, and downstream output must all be counted. | US5149407A patent record |
| Bedini pulse motor and battery charger claims | 1980s-2000s | battery / pulse charging | Replications claimed, no accepted over-unity proof | The claim family is best treated as battery-charging and pulse-motor experimentation unless a closed energy balance is published.Battery state of charge, sulfation recovery, pulse metering, and heat are easy to misread. | US6545444B2 patent record |
| Onboard HHO fuel-saver kits | 2000s-present | water fuel / engine aid | Common claim pattern | Hydrogen can be useful, but onboard electrolysis powered by the vehicle must overcome alternator load and conversion losses.Fuel-flow testing must include alternator power, battery state, gas production, and repeatable driving cycles. | DOE electrolysis overview |
| Steorn Orbo | 2006-2016 | magnet motor / commercial claim | Independent jury did not validate | The public validation effort did not demonstrate energy production, and the company later shut down.The claim never produced a transparent, independently replicated energy balance. | Steorn summary and references |
| Andrea Rossi E-Cat | 2011-present | excess heat / LENR claim | Controversial, not independently accepted | Claims of large excess heat remain outside accepted energy technology because independent access, calorimetry, and replication remain disputed.Secret fuel, limited independent control, and calorimetry questions dominate the evidence dispute. | Energy Catalyzer summary and references |
| Zero-point / Casimir generator claims | 1990s-present | quantum vacuum | Real effect, unsupported generator leap | Casimir forces are real nanoscale physics; they do not by themselves establish a resettable net-energy generator.A full cycle must include separation/reset work, actuation, losses, and environmental controls. | NIST Casimir context |
| Heat pump COP as over-unity proof | Recurring | legitimate technology misread | Category error | Heat pumps can deliver more heat than electrical input because they move environmental heat; that is not energy creation.The boundary must include environmental heat crossing into the system. | DOE heat pump guide |
FAQ
Is this a complete list of free-energy claims?
No. It is a compact research index of recurring, high-search-interest claim patterns and well-known examples.
Why are patents listed as sources for some claims?
A patent is useful for documenting what was claimed. It is not treated here as proof of net energy performance.
Why include heat pumps?
Heat pumps are legitimate technology, but their COP above 1 is often misused as an over-unity analogy. The table separates that category error.
