Moon juice
"Moon juice would also be hugely valuable for operations in Earth orbit, as it would be easier to get it there than it is to boost it up through Earth's powerful gravity well and troublesome atmosphere. Some have even suggested that lunar rocket-fuel factories could turn a tidy profit selling their product to satellite operators above Earth."
Erm, this stuff that's going to come back from the moon and fill up a satelite (I'm thinking some poor guy trudging down the hard shoulder with a petrol can). Unless I'm being really thick, then they have to get this petrol can up to the moon in the first place (and then back). Wouldn't it be easier just to fill up the petrol can here and send it? Unless this is going to be a reusable petrol can, which will mean servicing it in space.
Paris, cos she can fulfil servicing anywhere.
