Construction is underway of PlanetSolar, the first ship planned to circumnavigate the globe using solar power alone. The 30-metre ship will carry a permanent crew of two but can accommodate up to 50 for shorter trips - which, let's face it, includes almost anywhere.

PlanetSolar is being built in Kiel, Germany and, according to reports at Wired.com, will be able to maintain an average speed of 10 knots (11.5mph) throughout its 120-day voyage.
