Toward 100,000 Times More Efficient Gigawatt Interstellar Propulsion Beamed Power
by Brian Wang from NextBigFuture.com on (#6E601)
Jeffrey Gleason describes how to increase the space propulsion beaming range of an ion beam from 0.1 AU to 1000 AU by pinching the ion beam. He also describes getting 50 kilowatts per square meter of power by placing the beam generator at 0.05 AU (about the distance that the recent Parker Space Probe has ...
