[AT] Rocket stove for tractor shop

[Andy Glines]

I've been heating my shop with a standard wood stove for a long time and it does a pretty good job.  The stove is equipped with a blower and a waste oil drip.  The only thing that I don't like is the smoke and wasted heat that goes out the chimney.  I was reading a forum about compact diesel tractors and a member there mentioned rocket stoves.   They look like a pretty neat idea and I have most of the material needed to build one.  Has anyone on this forum ever played with rocket stoves?  What are your thoughts on them?
