Solar Impulse flight

The Solar Impulse took off early yesterday from San Francisco.  It will hopefully take the plane two months to make it all the way across the United States during its flight across the country. Bertrand Piccard and Andre Borschberg will take turns flying the tiny plane.

The plane utilizes energy which is collected in 12,000 solar cells. In turn, these cells charge batteries, which are equivalent to those found in small cars. This allows the aircraft to fly both during the day, and at night. This plane is certainly the first of its kind.
