Via this Global Strategy Institute blog posting, I came across this article and this article, through which I learned about a plane that is created to fly around the world powered entirely by solar energy. The wings of the plane will be covered with 250 square meters of solar-cells. Average flying speed is 70 km/h. Take off is in 2012. The budget for the project is EURO 70 million. Investors include Deutsche Bank, Omega, and Solvay. Mr. Bertrand Piccard and Mr. Andre Borschberg unveiled the plane at Dübendorf Airfield in Zürich, Switzerland today.
