A UC Berkeley researcher uses a magnifying glass to focus sunlight onto a small plastic boat. Nanotubes at one end of the boat absorb the sun’s heat, propelling the boat through the water. The second video shows a rotor that works on the same principle. A similar design could be used to make simple solar-powered pumps.
