[TheForge] eco coke

[Jerry Frost]

Get any video Pete? A neighbor of mine a few decades ago had a 55gl drum 
size kiln he fired with waste oil and not only managed to blow it over a 
reasonable area a couple times but melted it down once, literally.

Oil is SO much more volatile than (most) solid fuels. Guess I'll stop trying 
to design a charcoal powered auto.
