The idea behind this project is to create a dynamic environment of heat and cold to maximize the temperature differential on different sides of a thermopile made from numerous thermocouples.
The basic thermocouple housing unit will have two chambers, one nested inside the other. The inside chamber will house one end of the thermocouple and the outside chamber houses the other. Several hundred of these thermocouples working in series will produce a charge large enough to do some work.
Low pressure pumps will move cool water into the outside chamber where it will be heated by the sun. When a certain temperature is reached the pump will move it into the interior chamber of the next thermopile housing, heating one side of the the thermocouples. Cool water will be pumped into the outside side chamber creating a temperature differential and charge.
Rinse and repeat.
