Stirling CPU Cooler

Stirling CPU Cooler

I think this is pure genius. A simple version of a Stirling cycle engine used to cool a computer. A Stirling cycle engine runs when heat (or coolth) is applied externally to the engine. In this case the heat of the CPU powers the fan that cools it! No additional energy is required to run the fan. The temperature differential heats a gas in one cylinder and cools it in another cylinder. Pistons move. Work is done. Read more at Scientific American or Wikipedia

You can purchase a Stirling demonstration kit that will run off of the heat from a cup of coffee - Coffee Cup Stirling Engine
