Supplying fuel for a Mars expedition from the lunar surface is often suggested, but it's hard to make it pay off - Moon bases are expensive, and just buying more rockets to launch fuel from Earth is relatively cheap.

I don't collect the way other people do. Some people collect rare guitars, like, 'I have a '54 Strat worth $50,000.' And I don't collect the way Nash does. Nash has Duane Allman's guitar and Johnny Cash's guitar. I bought guitars because they sounded good. I played them, they sounded unbelievably good, and I couldn't resist.
