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.



Solar boats are boats powered by electric motors with storage batteries charged by photovoltaic cells. No other vehicle is better suited to transform light energy into mobility. The technique is quite advanced and has proven itself in practice. Much of the expanding long-distance goods traffic on our oceans as well as many leisure boats could be powered by ecological solar energy. Solar energy will be the future of navigation techniques. But it needs more publicity and more confidence.
