"Using nothing more than salt water and wind power, [scientists]have designed a device that will increase the reflectivity of some of the Earth's clouds, bouncing more incoming sunlight back into space...To produce this fine mist of sea spray artificially... thousands of unmanned yachts [would zigag] across the sea, carrying equipment to make very choppy waves, known as Faraday waves. A high-frequency ultrasonic generator would spin seawater around inside a grooved drum, producing tiny waves that are thinner than a human hair."
