Boat propels itself using water’s energy
U.S. scientists say they've designed a
mini boat that propels itself by harnessing energy contained in the water's surface.
University of Pittsburgh researchers said the technique destabilizes the surface tension surrounding the boat with an electric pulse and causes the craft to move using the surface's natural pull.
Cho and doctoral students Sang Kug Chung and Kyungjoo Ryu presented their findings Monday in Sorrento, Italy, during the Institute of Electrical and Electronics Engineers' 2009 Micro Electro Mechanical Systems conference.
