  2. Newman's energy machine - Wikipedia

    en.wikipedia.org/wiki/Newman's_energy_machine

    Newman's Energy Machine was a DC motor which the inventor, Joseph Newman, claimed to produce mechanical power exceeding the electrical power being supplied to it. In 1979, Newman attempted to patent the device, but it was rejected by the United States Patent Office as being a perpetual motion machine . [ 1 ]

  3. Free energy suppression conspiracy theory - Wikipedia

    en.wikipedia.org/wiki/Free_energy_suppression...

    Free energy suppression (or new energy suppression) is a conspiracy theory that technologically viable, pollution-free, no-cost energy sources are being suppressed by governments, corporations, or advocacy groups. [1][2] Devices allegedly suppressed include perpetual motion machines, cold fusion generators, torus -based generators, reverse ...

  4. Steorn - Wikipedia

    en.wikipedia.org/wiki/Steorn

    Steorn Ltd (/ ˈ s t j ɔːr n /) was a small, private technology development company based in Dublin, Ireland.In August 2006, it announced that it had developed a technology to provide "free, clean, and constant energy" via an apparent perpetual motion machine, something which is contrary to the law of conservation of energy, a fundamental principle of physics.

  5. Resonant inductive coupling - Wikipedia

    en.wikipedia.org/wiki/Resonant_inductive_coupling

    The energy will transfer back and forth between the magnetic field in the inductor and the electric field across the capacitor at the resonant frequency. This oscillation will die away at a rate determined by the gain-bandwidth (Q factor), mainly due to resistive and radiative losses. However, provided the secondary coil cuts enough of the ...

  6. Superconducting magnetic energy storage - Wikipedia

    en.wikipedia.org/wiki/Superconducting_magnetic...

    Unlimited cycles [1] Superconducting magnetic energy storage (SMES) systems store energy in the magnetic field created by the flow of direct current in a superconducting coil that has been cryogenically cooled to a temperature below its superconducting critical temperature. This use of superconducting coils to store magnetic energy was invented ...

  7. Thermoelectric generator - Wikipedia

    en.wikipedia.org/wiki/Thermoelectric_generator

    A thermoelectric generator (TEG), also called a Seebeck generator, is a solid state device that converts heat (driven by temperature differences) directly into electrical energy through a phenomenon called the Seebeck effect [1] (a form of thermoelectric effect). Thermoelectric generators function like heat engines, but are less bulky and have ...

  8. Magnet motor - Wikipedia

    en.wikipedia.org/wiki/Magnet_motor

    A magnet motor or magnetic motor is a type of perpetual motion machine, which is intended to generate a rotation by means of permanent magnets in stator and rotor without external energy supply. Such a motor is theoretically as well as practically not realizable. [1][2] The idea of functioning magnetic motors has been promoted by various hobbyists.

  9. Free energy - Wikipedia

    en.wikipedia.org/wiki/Free_energy

    Free-energy relationship, a relationship in physical organic chemistry. Principle of minimum energy, a thermodynamic formulation based on the second law. Thermodynamic free energy, the energy in a physical system that can be converted to do work, including: Gibbs free energy. Landau free energy (also known as grand potential)
