These rocks burn, that's good thing.
I expect that coal liquefaction will prove cheaper, but bring it all on.
Is it coal liquefaction? I've hear of coal gasification, and soil liquefaction under earthquake conditions, but not coal liquefaction. Not trying to be a dick, just never hear the term.
In any case, the wizards at Mega Oil know what price per barrel is necessary to extract oil from the shale. I have to beleive they are there, but are concerned if the price will stay as high as it is. I remember reading about oil shale as a kid, and they do have the big oils sands operation currently extracting oil way up in Canada.
