I first got interested in rocket stove back in the 90's and ran into this site.http://aprovecho.org/
They've been working on them since the 70's in third world countries as a way to keep women for having lung problem. Alot of there designs aren't portable but
it's an interesting site.

Where ever we raise the hatch is home.
Darn blank states keep getting further away and we keep traveling slower ain't never gona get this map full.
