Actually, NASA has been playing with this idea, in the 70's...rabidvixen wrote:The microscoop works in a completely different manner. It collects minute particles of hydrogen and other elements ....
The project was called PROFAC, consisting of a nucular powersource, empty tanks, a radiator and some compressors. Oh, and a funnel-shaped 'gathering' thingy.
It would orbit around LEO, collecting the atomic Hydrogen, that's still there, though in minimal amounts, and cool/compress it to liquid hydrogen, to refuel spacetugs. (another thing they had on the drawing tables, sigh...)
PROFAC never got far beyond the drawing tables, because of the 'nucular' plant, but you see, the idea has merit!
