Gilboa's team has built a buoy that rides the waves. At the top of the crest, and only at the top, the buoy unlocks and shoots upwards thus generating energy. As a result, the buoy can produce electricity with a zero carbon footprint, Gilboa said. The company claims their system produces much more energy than other wave-buoy devices.
However, over and above electricity production, the buoys can desalinate water. The buoy utilizes the pressure of the jump upwards at the wave's crest to push sea water through reverse osmosis membranes, turning sea water into distilled pure water.
