  2. 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 ...

  3. 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.

  4. Wind turbine - Wikipedia

    en.wikipedia.org/wiki/Wind_turbine

    A wind turbine is a device that converts the kinetic energy of wind into electrical energy. As of 2020, hundreds of thousands of large turbines, in installations known as wind farms, were generating over 650 gigawatts of power, with 60 GW added each year. [ 1]

  5. 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 ...

  6. Electrical grid - Wikipedia

    en.wikipedia.org/wiki/Electrical_grid

    An electrical grid (or electricity network) is an interconnected network for electricity delivery from producers to consumers. Electrical grids consist of power stations, electrical substations to step voltage up or down, electric power transmission to carry power over long distances, and finally electric power distribution to customers.

  7. Ion wind - Wikipedia

    en.wikipedia.org/wiki/Ion_wind

    An electrostatic pinwheel, or corona spinner, attached to a small Wimshurst machine (electrostatic generator) is shown stationary and rotating. Ion wind, ionic wind, corona wind or electric wind is the airflow of charged particles induced by electrostatic forces linked to corona discharge arising at the tips of some sharp conductors (such as points or blades) subjected to high voltage relative ...

  8. Energy storage - Wikipedia

    en.wikipedia.org/wiki/Energy_storage

    Energy storage is the capture of energy produced at one time for use at a later time [ 1] to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential ...
