CaroKann writes "In the middle of May 2008, Kenichi Horie, an adventurer known for such feats as paddling a pedal powered boat 4,660 miles from Hawaii to Okinawa in 1993, will be sailing a wave powered boat from Honolulu's Hawaii Yacht Club to the Kii Channel in Japan. The boat, a 3-ton catamaran named the Suntory Mermaid II, works by virtue of the fins located at the front of the boat. These fins "generate thrust force by moving up and down like the tails of dolphins and whales and absorbing the energy of the waves." The system can propel the boat no matter which direction the waves come from. Because the wave propulsion system absorbs the energy from the waves, a passenger on the boat will experience a smooth ride. With a top speed of about 5 knots, the journey is expected to take about 2 to 3 months."
