Mechanical Power by Linking Earth’s Warmth to Space

Caption

UC Davis engineering professor Jeremy Munday has developed an experimental engine that can generate mechanical power from the temperature difference between the Earth and deep space when placed outdoors at night. The device, a type of machine called a Stirling engine, could be used for example to ventilate buildings or run fans in a greenhouse at night.
