【Pure water】Solar-Powered Plane
|
||
 The plane is not designed to carry passengers The long-awaited take-off of the Solar Impulse was greeted with delight by those who have spent the last seven years working on it. The solar-powered plane has the wing-span of a jumbo jet, but weighs less than a family car. It doesn't use a single drop of aviation fuel, instead its giant wings are covered with solar cells. The project is the brainchild of Swiss adventurer Bertrand Piccard - he sees the Solar Impulse as a sign of things to come. "I don't know exactly how commercial airliners will fly in twenty years. But I know for sure that they are not going to fly like today. If an aeroplane can fly around the world with no fuel, nobody can say afterwards that it's impossible to do the same for cars or heating systems or whatever." But the Solar Impulse won't replace conventional air travel. Its top speed is just 44 miles an hour (70kph). Nevertheless Bertrand Piccard hopes to fly the plane around the world in 2012, thus continuing a long family tradition. His grandfather was the first man to take a balloon into the stratosphere. His father took a submarine to the deepest point of the Pacific Ocean. Now Bertrand Piccard hopes to show the world just what can be achieved with a little bit of sunshine. |
