I hate to point out the obvious . . . but if oil sells for $50 a barrel, these guys can make it for $15, why not patent the process and just sell it for $49 a barrel. That one dollar differences is BILLIONS in profit.
But the point is that if oil could be made for $15 a barrel, no one would pay $50 for it pumped out of the ground.
One problem is where to get 600 million tons of turkey guts. Thee aren't that many turkeys.
