    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 ...

  7. 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.
