Solar Goes Transcontinental June 1, 2012 : 8:48 PM

Another hallmark for renewable energy ­ the first solar powered transcontinental flight:

"An experimental solar-powered airplane took off from Switzerland on its first transcontinental flight Thursday, aiming to reach North Africa next week."

"Pilot Andre Borschberg planned to take the jumbo jet-size Solar Impulse plane on its first leg to Madrid, Spain, by Friday. His colleague Bertrand Piccard will take the helm of the aircraft for the second stretch of its 2,500-kilometer (1,554-mile) journey to the Moroccan capital Rabat."
