PlanetSolar's solar-powered catamaran

When the sun shines on this big catamaran, don't go looking for passengers lounging on deck chairs. All that sunlight will be going into the boat's 38,000 or so solar cells.

The catamaran is the focus of the PlanetSolar project, which aims to take the boat on a round-the-world cruise starting in early 2011. The photo here is from its coming-out party Thursday at the HDW Shipyard in Germany.
