World’s Largest Solar Powerd Ship

The 31m long and 15m wide craft is able to capture nearly 103.4 kW of solar energy to power its engine which normally needs 20kW, to reach an average speed of 8 knots (15kph or9mph). Although it is possible it can “swim” twice faster.
The 60 tonne catamaran costs 18 million euro ($24.4 million USD). The ship was created at the Knierim Yacht Club in KielNorthern Germany, and was launched successfully in March,2010, after 14 months of building. To achieve to full photovoltaic capture there are solar covered flaps that are extended at the stern and amidships.
SunPower has provided approximately 38,000 of their next generation all black photovoltaic cells, that have an efficiency of at least 22%, which they believe to be the highest efficiency solar cells available on the market.
The projects was conceived by Raphaël Domjan, a citizen of Switzerland , who with Frenchman Gérard d’Aboville, made the world’s first sailing around the world powered by solar energy. Their trip ended on May,4th,2012, covering a distance of more than 60 000 km.
Although not intended to replace conventional watercraft, the PlanetSolar team make a note that it was boats that allowed the first great explorations of our world. But with the first boat dating back more than 10,000 years we seem to have forgotten how clean such transport can be. “Today the boat is the most used means of transport of goods. It represents single-handedly almost 1,4 billions of tons of carbon dioxide (in 2008), that is 6% of the total carbon dioxide emissions and twice more than the air transport.”
