French captain Erwann Le Rouzic gestures onboard Turanor PlanetSolar, the first solar-powered boat to travel around the world, after arriving in Hong Kong. Turanor PlanetSolar, a 31- by 15-metre white catamaran, was unveiled to the world last year and has embarked on a world tour from Monaco since September 2010 to promote solar energy for pollution-free shipping. The Swiss-flagged boat, which was built in Germany and cost US$26 million, is topped by 500 square metres of black solar panels, with a bright white cockpit sticking up in the centre.
