How much oil does it take just to move a ton of rock around?

Seems like there is a third option -- dig a giant hole, put a thermonuclear device in and blow it up. The resulting heat and pressure should make oil out of the shale, which in due course could be pumped up out of the hole. I suppose we might have to wait a while for the radiation to go down, though.

I'm looking for investors....

that idea is not as far fetched as you might imagine, the us doe, your tax $'s at work, attempted such a stunt in western colorado. an attempt to fracture the rock with a "small" blast to stimulate gas production. and they were succesful in fracturing the rock but as you have guessed, the produced gas was radioactive.

Now there's a justification for CO2 sequestration if I ever saw one.
