Microwaves?.........Hmmmm.......Sounds good. he Environazis will find a problem with it though.......
Hogwash--the big question is how much the "microwaves" cost in relation to how much kerogen you get out of the marlstone---
Way ahead of you - the big coal and shale areas are probably locked up/sold/leased/whatever long ago..
Canada is extracting oil from their sand, and their “Environazis” have allowed it under the condition that the land be returned to a natural state, not left trashed and useless. If our oil companies would guarantee to me, a tree hugger, who knows I do not own this world, but my Father the Creator does, that they would clean up their mess, and plant new trees or grass or whatever, then go ahead. But I’ll be watching! Or my grandkids:)
