Thermoelectric generators function like heat engines, but are less bulky and ...
Droop speed control is a control mode used for AC electrical power generators, whereby the power output of a generator reduces as the line frequency increases. It is commonly used as the speed control mode of the governor of a prime mover driving a synchronous generator connected to an electrical grid. It works by controlling the rate of power ...

The absorption of longwave radiation prevents it from reaching space, reducing the rate at which the Earth can cool off. Without the greenhouse effect, the Earth's average surface temperature would be about −18 °C (−0.4 °F), [15] [16] which is less than Earth's 20th century average of about 14 °C (57 °F), or a more recent average of ...
