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 […]

These bladeless wind turbines shake to generate electricity

Farms dotted with the gigantic spinning blades of wind turbines have become a standard sight on long-distance road trips, but what if there was another way to capture energy from the wind? A startup out of Spain is working on that very idea. The company’s called Vortex Bladeless, and its turbines look like stalks of […]
