writes, "A group from Switzerland will soon attempt the first Atlantic crossing in a solar-powered boat. This ship, named SUN21, is a 14-meter-long catamaran able to sleep 5 or 6 persons. The goal is to leave Seville, Spain, in December 2006 and to reach ports in Florida and New York in the spring of 2007. This boat will achieve its 7,000-mile trip at a speed of 5-6 knots, about the speed of a sailing yacht, by using photovoltaic cells and without burning a single gallon of fuel. The consortium behind this project wants to demonstrate that the time has come for solar boats."
The boat will cost about $556,000 to build and it will be for sale at some point after its crossing.
