The Transatlantic21 is going to cross the ocean with no gas, instead it will use only solar power! After a successful voyage they will sell solar powered boats based on the successful design.
“The time is ripe for a breakthrough of solar techniques into the world of boat and ship navigation. Demonstrating the potential of solar power is the objective of Transatlantic21. In September 2006, “SUN21″, which has been constructed specifically for this purpose, will begin its journey from Basel to New York. It will be the first solar boat ever to cross the Atlantic: entirely dependent on sunlight, not consuming one drop of gasoline.”
