By the end of this month (June 2009) a revolutionary new aircraft will be presented that is powered by solar power. The aircraft, named the SolarImpulse, has a wing span similar to the A340 (some 180 feet), weighs some 1.600 kilograms, has an engine which is capable of delivering 40cc, and is planned to make its first flight in 2010. The SolarImpulse has 11.628 solar cells across its wings, four propellor engines, and is able to stay airborne for 36 hours at a speed of 70 km/h. After five years of research and development, prototype HB-SIA will be revealed on June 26 at Dübendorf airport, near Zürich.
