Thermal Differential Energy

This is the energy made from the difference in temperatures.

Where air temperature differences exist between two separated areas. If the hotter air is allowed to leave through a central vent and the cooler air is able to replace it through surrounding vents, the speed at which this hot air escapes and is replaced creates energy.

Example and application

Under a large glass roof the sun warms up the air (greenhouse effect) which escapes via a central vertical cylindrical tube (chimney effect). This movement of hot air (updraft wind), thus created, can drive turbines/generators at the base of the chimney and so generates electricity. This thermal principle is exploited by the Solar Cyclone Tower TM as further explained herein.
