liqs8143 writes "Solar Impulse, a fully solar-powered airplane has completed the world's first international solar-powered flight. After a flight lasting 12 hours 59 minutes at an altitude of 12,400 feet, using no fuel and propelled by solar energy alone, Solar Impulse HB-SIA landed safely in Brussels, Switzerland.
After the landing, plane's co-founder Bertrand Piccard said:
Our goal is to create a revolution in the minds of the people . . . to promote solar energies — not necessarily a revolution in aviation.
Compared with 2003, energy efficiency has increased from 16 to 22 percent. And the cells are now half as thick.
The project has a total cost of $88 million which is funded by mostly-Swiss partners and public donations."
