69-year-old Japanese sailor Ken-ichi Horie captained the world’s most advanced wave-powered boat 4,350 miles from Hawaii to Japan, the longest distance traveled by a wave-powered boat and, along the way, show off the greenest nautical propulsion system since the sail.
He does a media of 1.5 knots or so, like two miles per hour, because the weather was excessively calm for that  seasson.
