Solar takes to the skies. The Solar Impulse took flight today, reaching an altitude of 5500 feet over 87 minutes.With a wingspan of over 60 meters, close to that of a Boeing 747, it weighs about as much as a small car. Its 12,000 solar cells generate power for the 40hp engine, with an average speed of 70 kph (44 mph). The team will continue testing the prototype, including a 36 hour overnight flight, before constructing an even lighter, more powerful, more stable plane, with the goal of flying around the world in 2012, traveling both during both the day and at night, without fuel.
