Rob Kennedy writes "A story at The Daily Cardinal is reporting that UW-Madison researchers are looking to mine the moon for helium-3 as an energy source, which supposedly would yield about 1000 times more energy per pound than coal. Although there are several hurdles that would need to be cleared, The Associated Press mentions one catch in particular: 'The researchers still are working on building a helium-3 reactor that would produce more energy than it takes in.' Indeed. SciScoop has a more in-depth discussion of the prospect."
