Scientists build toy car propelled by evaporating water

Researchers at Columbia University in New York have built a miniature car that draws on the process to propel itself along, as well as an evaporation-driven generator that powers a flashing LED lamp. The inventions pave the way for a new generation of renewable devices that extract energy from natural evaporation and transform it into […]
