Actually down Here I have plenty of oil, hope the price rises, although I am working on a bio fuel, using waste to grow earth worms and turning them into bio gas and bio diesel.
I am thinking about Huff and Puffing my oil soon, so that it will produce a good source of income, tons of Oil leases in Kentucky with 70 percent of he oil still in the ground.
Only 30 percent of an oil resource can be produced at the present time, Huff and Puff raises that to 60 percent total production, still leaving 40% that is unreachable.
Corn will never work sorghum cane is however a very efficient fuel, high sugar content.
PS. the reason I am experimenting with earth worms is they eat waste, do not need sunlight of fertilizers, and the resulting castings make good fertilizers. It is a win win situation.
My grandfather in Kentucky used to make some really efficient "fuel" from sorghum (if you know what I mean).
