The Wave Powered Boat.

"This month, 69-year-old Japanese sailor Ken-ichi Horie will attempt to captain the world’s most advanced wave-powered boat 4,350 miles from Hawaii to Japan. If all goes as planned, he’ll set the first Guinness world record for the longest distance traveled by a wave-powered boat and, along the way, show off the greenest nautical propulsion system since the sail."

Ken-ichi's boat, the Suntory Mermaid II, uses a recycled-aluminum catamaran that converts the waves in forward motion. "Two fins mounted side by side beneath the bow move up and down with the incoming waves and generate dolphin-like kicks that propel the boat forward. 'Waves are a negative factor for a ship—they slow it down,' says Yutaka Terao, an engineering professor at Tokai University in Japan who designed the boat’s propulsion system. 'But the Suntory can transform wave energy into propulsive power regardless of where the wave comes from.' "
