AC Propulsion - Electric Aircraft

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:

    “The sight of a planet through a telescope is worth all the course on astronomy; the shock of the electric spark in the elbow, outvalues all the theories; the taste of the nitrous oxide, the firing of an artificial volcano, are better than volumes of chemistry.”
    —Ralph Waldo Emerson (1803–1882)
