[Gasification] [biochar] Pine char gasification

[Jeff Davis]

I'm sure this is not the case but a refrigerator can be made from two 
clay pots, one smaller than the other, charcoal and a cloth top. The 
smaller pot fits inside the larger one with charcoal (or sand) betwixt 
them. Add water to the charcoal and cloth plus evaporation. I also doubt 
that it would work in the steamy jungles. Just thought I'd toss that out 
there.
