  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. Thermoelectric effect - Wikipedia

    en.wikipedia.org/wiki/Thermoelectric_effect

    A thermoelectric device creates a voltage when there is a different temperature on each side. Conversely, when a voltage is applied to it, heat is transferred from one side to the other, creating a temperature difference. This effect can be used to generate electricity, measure temperature or change the temperature of objects. Because the ...

  4. Radioisotope thermoelectric generator - Wikipedia

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

    Radioactive decay of the fuel produces heat. It is the temperature difference between the fuel and the heat sink that allows the thermocouples to generate electricity. A thermocouple is a thermoelectric device that can convert thermal energy directly into electrical energy using the Seebeck effect. It is made of two kinds of metal or ...

  5. Electricity generation - Wikipedia

    en.wikipedia.org/wiki/Electricity_generation

    They generate power by burning natural gas in a gas turbine and use residual heat to generate steam. At least 20% of the world's electricity is generated by natural gas. Water Energy is captured by a water turbine from the movement of water - from falling water, the rise and fall of tides or ocean thermal currents (see ocean thermal energy ...

  6. Sources of electrical energy - Wikipedia

    en.wikipedia.org/wiki/Sources_of_electrical_energy

    Heat: Energy produced by heating the junction where two unlike metals are joined. Light: Energy produced by light being absorbed by photoelectric cells, or solar power. Chemical: Energy produced by chemical reaction in a voltaic cell, such as an electric battery. Pressure: Energy produced by compressing or decompressing specific crystals.

  7. Thermoelectric materials - Wikipedia

    en.wikipedia.org/wiki/Thermoelectric_materials

    The efficiency of a thermoelectric device for electricity generation is given by , defined as =.. The maximum efficiency of a thermoelectric device is typically described in terms of its device figure of merit where the maximum device efficiency is approximately given by [7] = + ¯ + ¯ +, where is the fixed temperature at the hot junction, is the fixed temperature at the surface being cooled ...

  8. 7 Best Heated Cat Houses for Outdoor Cats to Keep Them Warm ...

    No, heated outdoor cat houses are designed to be energy-efficient. Most use low-wattage heating pads, typically consuming between 10 to 40 watts — about the same as a small light bulb.

  9. Thermopile - Wikipedia

    en.wikipedia.org/wiki/Thermopile

    Thermopiles are also used to generate electrical energy from, for instance, heat from electrical components, solar wind, radioactive materials, laser radiation or combustion. The process is also an example of the Peltier effect (electric current transferring heat energy) as the process transfers heat from the hot to the cold junctions.
