Solar Impulse - A Pioneer Sun Salute ! | Aviation & Airliners |

The next milestone for the project, according to Piccard is the construction of a second prototype, the HB-SIB, with lighter, thinner solar cells and more efficient systems. This next iteration will expand the scope of solar flight to long-haul missions lasting several days, with a planned crossing of the Atlantic Ocean in 2011. The acme of the entire project is expected in 2013 when the plane will attempt to circumnavigate the globe in 25 days, dramatically abbreviating Jules Verne’s iconic dream of going around it in 80.
