PlanetSolar

World's biggest solar powered boat sets sail. This sleek catamaran-styled yacht, named the PlanetSolar, measures 102 feet long, almost 50 feet wide and 24-1/2 feet high (31 meters by 15 meters by 7.5 meters), but its most interesting feature is that it’s covered with 5,382 sq ft (500 sq m) of solar panels that gather sunlight and help it sail the sea nice and smooth.
Built by Knierim Yachtbau and designed by PlanetSolar SA of Switzerland, the world’s largest solar boat has a futuristic shape that gets the eye. The vessel has been unveiled for the first time during a press event held at the HDW shipyard in Kiel.

Eco-shop

A businessman in Berlin has leapt on the "green" bandwagon by offering discounts to clients who can prove they arrived by public transport or bicycle. "Everyone's a winner," explained Regina Goetz, who runs the business in Berlin's Prenzlauer Berg, a district in the former East Berlin.
"It's pretty difficult to park around here. So we came up with the idea of an eco discount of five euros (£4.50) to anyone who leaves the car at home," Ms Goetz. "The crisis has slashed our turnover to half in the last year. But the discount has proved a roaring success," she said.
