Researchers at MIT have followed up on their discovery that droplets of water acquire an electric charge when jumping from certain condenser surfaces by finding a way to make use of that effect: They found that by applying an electric field to the system, the droplets "jump" more rapidly away from the surface. In this way, the efficiency of heat transfer from that surface can be nearly doubled.
