  2. Atmospheric electricity - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_electricity

    Atmospheric electricity describes the electrical charges in the Earth's atmosphere (or that of another planet). The movement of charge between the Earth's surface, the atmosphere, and the ionosphere is known as the global atmospheric electrical circuit. Atmospheric electricity is an interdisciplinary topic with a long history, involving ...

  3. Telluric current - Wikipedia

    en.wikipedia.org/wiki/Telluric_current

    Telluric current. A telluric current (from Latin tellūs 'earth'), or Earth current, [1] is an electric current that flows underground or through the sea, resulting from natural and human-induced causes. These currents have extremely low frequency and traverse large areas near or at Earth 's surface. Earth's crust and mantle are host to ...

  4. Global atmospheric electrical circuit - Wikipedia

    en.wikipedia.org/wiki/Global_atmospheric...

    A global atmospheric electrical circuit is the continuous movement of atmospheric charge carriers, such as ions, between an upper conductive layer (often an ionosphere) and surface. The global circuit concept is closely related to atmospheric electricity , but not all atmospheres necessarily have a global electric circuit. [ 2 ]

  5. Atmospheric water generator - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_water_generator

    An atmospheric water generator (AWG), is a device that extracts water from humid ambient air, producing potable water. Water vapor in the air can be extracted either by condensation - cooling the air below its dew point, exposing the air to desiccants, using membranes that only pass water vapor, collecting fog, [1] or pressurizing the air.

  6. Kelvin water dropper - Wikipedia

    en.wikipedia.org/wiki/Kelvin_water_dropper

    The Kelvin water dropper, invented by Scottish scientist William Thomson (Lord Kelvin) in 1867, [1] is a type of electrostatic generator. Kelvin referred to the device as his water-dropping condenser. The apparatus is variously called the Kelvin hydroelectric generator, the Kelvin electrostatic generator, or Lord Kelvin's thunderstorm.

  7. Solar updraft tower - Wikipedia

    en.wikipedia.org/wiki/Solar_updraft_tower

    The solar updraft tower (SUT) is a design concept for a renewable-energy power plant for generating electricity from low temperature solar heat. Sunshine heats the air beneath a very wide greenhouse-like roofed collector structure surrounding the central base of a very tall chimney tower. The resulting convection causes a hot air updraft in the ...

  8. Electrostatic generator - Wikipedia

    en.wikipedia.org/wiki/Electrostatic_generator

    12" Quadruple Sector-less Wimshurst Machine (Bonetti Machine) 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 ...

  9. Energy conversion efficiency - Wikipedia

    en.wikipedia.org/wiki/Energy_conversion_efficiency

    Energy conversion efficiency (η) is the ratio between the useful output of an energy conversion machine and the input, in energy terms. The input, as well as the useful output may be chemical, electric power, mechanical work, light (radiation), or heat. The resulting value, η (eta), ranges between 0 and 1. [1][2][3]
