Rocket Mass Heater Overview

Series of clips starting from just after lighting. Shows wood burning, overview of the barrel and bench plus temperature on barrel top (~400*F - have seen it as high as ~550*F) and the (consistent) 90*F reading on the bench itself near the burn tunnel and feed tube. This area is about 15 cubic feet of solid cob between the bench and the burn tunnel, so quite a lot of mass there. Farther down the bench, the surface temperature stays more around 70*F.
