Solar powered plane to circle the globe
The Solar Impulse is the brain child of Bertrand Piccard, a Swiss adventurer and environmentalist, who launched the project back in 2003 with the aim of promoting the use of renewable energy sources. Now, in 2009, he is closing in on that dream. His plane has a 200-foot wingspan which is lined with 12,000 photovoltaic solar cells that will draw energy from the sun to power its four engines.
Piccard unveiled the latest design for his plane on June 26th in a ceremony near Zurich. This prototype will undergo test flights in 2010, including night flights using solar power stored in batteries. In 2011 the next design of the plane will be completed, with 2012 set as the tentative start of its world tour. The fact that this plane can fly even at night is one of the the things that separates it from other solar powered aircraft in the past.
While we might be years away from solar power becoming commercially viable for flights, it is projects like these that are paving the way for the future of flight. A future that is clean and environmentally friendly.
