Solar Impulse to fly across U.S. with no fuel

1 post in this topic

Recommended Posts


The Solar Impulse is a plane powered only by solar power. It does not require any fuel, only the sun shining on its 11,628 photovoltaic cells in order to fly. Powered by four 10HP engines, it can achieve speeds of up to 43 mph and is designed to fly for up to 36 hours without a break.

The plane has already completed flights from Switzerland to Spain and also to Morocco, but creator Bertrand Piccard is preparing to undertake a flight across America, which begins tomorrow with a number of technical flights to do some final checks. The actual 2013 Across America Mission will begin on May 1st.


Though by reading the article, I don't think that it is actually a plane, so to speak. More like a remote controlled drone.
