PlanetSolar, when completed and covered with 1500 square feet of solar panels, will be the largest solar powered ship in the world. A ship with an audacious agenda: to be the first to circumnavigate the globe powered solely by solar energy.
“In 2010, the first round-the-world trip powered by solar energy will be realized, with stopovers, along the equator, where the maximum amount of sunlight is available. The over 40,000-km voyage will last 120 days, for an average speed of 10 knots. PlanetSolar’s two-man crew will cross the Atlantic Ocean, the Panama Canal, the Pacific Ocean, the Indian Ocean and finally the Suez Canal, to return to the Mediterranean.”

This 100% biodiesel-powered, 78 ft wave-piercing trimaran aims to set an around-the-world speed record while maintaining a net zero carbon footprint. The Earthrace left Sagunto, Spain, on April 27, and has already made excellent time across the Atlantic, landing in Panama just 8 days later.
Inspired by the desire to “connect with people about the need to get renewable fuels into our energy mix and to inspire them to do something,” the Earthrace has already generated a whirlwind of publicity. Much of this is due to the boat’s eco-technological appeal. It’s been described as “a rally car but for oceans”, with the ability to submerge up to 23 feet underwater while powering through the ocean. The “eco-” part doesn’t just include circling the globe on 100% biodiesel. Parts of the boat are made from a hemp-based composite, bedding foams are made from canola oil, and the operation’s total carbon footprint has been balanced by purchasing carbon credits.
