  2. 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.

  3. 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 ...

  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 .

    However, his system was only intended to transmit energy for free; the system's energy would still need to be generated through conventional means. [20] Notable proponents of the conspiracy theory include Gary McKinnon, a Scottish computer hacker who unlawfully accessed computer systems to look for evidence of a secret free energy device. [21]

  6. Thermophotovoltaic energy conversion - Wikipedia

    en.wikipedia.org/wiki/Thermophotovoltaic_energy...

    Thermophotovoltaic (TPV) energy conversion is a direct conversion process from heat to electricity via photons.A basic thermophotovoltaic system consists of a hot object emitting thermal radiation and a photovoltaic cell similar to a solar cell but tuned to the spectrum being emitted from the hot object.

  7. Electrostatic generator - Wikipedia

    en.wikipedia.org/wiki/Electrostatic_generator

    An electrostatic generator, or electrostatic machine, is an electrical generator that produces static electricity, or electricity at high voltage and low continuous current. The knowledge of static electricity dates back to the earliest civilizations, but for millennia it remained merely an interesting and mystifying phenomenon , without a ...

  9. Radioisotope thermoelectric generator - Wikipedia

    en.wikipedia.org/wiki/Radioisotope...

    Diagram of an RTG used on the Cassini probe. A radioisotope thermoelectric generator (RTG, RITEG), sometimes referred to as a radioisotope power system (RPS), is a type of nuclear battery that uses an array of thermocouples to convert the heat released by the decay of a suitable radioactive material into electricity by the Seebeck effect.
