100% Solar Powered Aircraft

Jun-17-09 The "Solar Impulse project" have assembled a prototype set to be unveiled to the public for the first time on June 26th. Entirely powered by the sun, the aircraft designated HB-SIA has a giant wingspan of 61 meters and is covered in almost 12,000 solar cells.

The four lithium batteries used to power the engines each weighs 220lbs. Yet, by using carbon fiber construction, the entire weight of the plane has been kept to only around 3,300lbs (1500kgs) or roughly that of a car.

It’s expected that the Solar Impulse’s first test flight will take place towards the end of this year.
