Electric Aircraft
Cocconi built an unmanned aircraft of 16.4-foot (5m) span, and in 2005 demonstrated its ability to fly 48 hours nonstop, propelled by solar energy alone. This was the first around-the-clock flight of such a propulsion system, carried only by solar energy collected and stored in onboard batteries.

Famous quotes containing the word electric:
“Persons grouped around a fire or candle for warmth or light are less able to pursue independent thoughts, or even tasks, than people supplied with electric light. In the same way, the social and educational patterns latent in automation are those of self- employment and artistic autonomy.”
—Marshall McLuhan (1911–1980)
