  2. Joseph Westley Newman - Wikipedia

    en.wikipedia.org/wiki/Joseph_Westley_Newman

    Joseph Westley Newman (July 2, 1936 – March 6, 2015) was an American inventor and author who developed an "energy machine" which he attempted to patent, but was rejected by the US Patent and Trademark Office on grounds of being a perpetual motion machine. He described this device in a book, The Energy Machine of Joseph Newman.

  3. 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) Helmholtz free energy

  4. Electric generator - Wikipedia

    en.wikipedia.org/wiki/Electric_generator

    The energy source harnessed to turn the generator varies widely. Most power stations in the world burn fossil fuels such as coal , oil , and natural gas to generate electricity. Cleaner sources include nuclear power , and increasingly use renewables such as the sun , wind , waves and running water .

  5. Electricity generation - Wikipedia

    en.wikipedia.org/wiki/Electricity_generation

    Electricity generation is the process of generating electric power from sources of primary energy.For utilities in the electric power industry, it is the stage prior to its delivery (transmission, distribution, etc.) to end users or its storage, using for example, the pumped-storage method.

  6. Earth battery - Wikipedia

    The free electrons then flow into one electrode to a greater degree than in the other electrode, thereby causing electric current to flow in the external circuit through the load. The current flows from that plate whose position in the electropotential series is near the negative end (such as palladium). The current produced is highest when the ...

  7. Thermoelectric generator - Wikipedia

    en.wikipedia.org/wiki/Thermoelectric_generator

    Every human activity, transport and industrial process generates waste heat, being possible to harvest residual energy from cars, aircraft, ships, industries and the human body. [1] From cars the main source of energy is the exhaust gas. [32] Harvesting that heat energy using a thermoelectric generator can increase the fuel efficiency of the car.

  8. Thermodynamic free energy - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_free_energy

    Therefore, only relative free energy values, or changes in free energy, are physically meaningful. The free energy is the portion of any first-law energy that is available to perform thermodynamic work at constant temperature, i.e., work mediated by thermal energy. Free energy is subject to irreversible loss in the course of such work. [1]

  9. 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 ]
