An experimental device consisting of a black-painted aluminum disk mounted on a roof that captures heat radiating into space and converts it into electricity using a thermoelectric generator. The prototype produced 25 milliwatts per square meter and was built for less than $30.

A natural phenomenon where surfaces facing the sky release heat as thermal radiation into the atmosphere and space. The technology captures this temperature difference to generate electricity.

Powered by the captured heat from the fuel cells, this generator contributes to the vehicle's overall energy system.
