astroengine writes "When considering the fuel source for a fusion-powered interstellar probe, wouldn't it be a good idea to set up a colony on the moon and start pillaging the lunar surface for its helium-3 riches? Not so fast, says Adam Crowl of Project Icarus, there may be a far more viable source. What about the gas giants? Although Jupiter's gravity could pose a problem and Saturn's rings might get in the way (and forget Neptune, that place is one hell of a commute), perhaps the helium-3 in the Uranian atmosphere could be mined using atmospheric balloons?"
