Earlier this week, the Swiss made solar boat, Sun21, reached New York, the final destination on the first-ever sun powered transatlantic journey. Sun21 sailed 13,000 kilometers from Chipiona in Spain to the island of Martinique and along the East Coast of the United States. The boat produced a reported 2,000 kilowatt-hours of solar energy that powered electric motors with surplus energy stored in batteries. This allowed Sun21 to travel a constant speed of 5 to 6 knots per hour throughout its voyage, which started in October 2006. As one of the crew members stated, this proves on a small scale what can be done globally to address the threat of climate change.
