All we have to do is keep the people away from the oil fields.
While you're at it please explain just how we can make oil out of coal? They tried to make gas (Methane) out of it in the mid '70's, but oil was not possible. Did some new miracle technology just spring up out of nowhere?
The same way the Germans did in WWII, it's easy, its just costs a little more than crude does now. Could you be confusing coal with shale?
