2. Vaneless ion wind generator - Wikipedia

   en.wikipedia.org/wiki/Vaneless_ion_wind_generator

   Sustainable energy. A vaneless ion wind generator or power fence is a device that generates electrical energy by using the wind to move charged particles across an electric field . Ion wind generators are not commercially available, though working prototypes and proofs of concept have been created.

3. Wind turbine - Wikipedia

   en.wikipedia.org/wiki/Wind_turbine

   A forerunner of modern horizontal-axis wind generators was in service at Yalta, USSR, in 1931. This was a 100 kW generator on a 30-meter (98 ft) tower, connected to the local 6.3 kV distribution system. It was reported to have an annual capacity factor of 32 percent, not much different from current wind machines. [citation needed]

4. Antique radio - Wikipedia

   en.wikipedia.org/wiki/Antique_radio

   Other farm radios were designed to run on 32 V DC, from a bank of lead-acid storage batteries charged from a gas powered generator or a wind-charger. The 32-volt system could also power other specially made appliances as well as electric lights around the farm. Other farm radios, especially from the late 1930s to the 1950s, reverted to using a ...

5. Mechanically powered flashlight - Wikipedia

   en.wikipedia.org/wiki/Mechanically_powered...

   Mechanically powered flashlights were distributed by aid organizations to survivors of the 2010 Haiti earthquake since electric power was lost for a long period. A mechanically powered flashlight (UK: mechanically powered torch) is a flashlight that is powered by electricity generated by the muscle power of the user, so it does not need ...

6. Thermoelectric cooling - Wikipedia

   en.wikipedia.org/wiki/Thermoelectric_cooling

   Thermoelectric cooling. Thermoelectric cooling uses the Peltier effect to create a heat flux at the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending ...

7. Electric generator - Wikipedia

   en.wikipedia.org/wiki/Electric_generator

   In electricity generation, a generator[ 1] is a device that converts motion-based power ( potential and kinetic energy) or fuel-based power ( chemical energy) into electric power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even ...
