I'm going to be making a rocket mass heater to heat a polycrub in the colder months.
it's for a community growing space and we are completely off the grid so I've been looking at power sources.
has anyone ever integrated a Stirling engine to a rms?
I'm thinking its killing 2 birds with one stone.
So far as I know, there are no commercially available sterling engines that produce useful amounts of output. This is especially true for anything designed to work with a solid fuel burning device like a rmh.
If you are aware of one, I would love to know about it.

The Stirling engines I have seen in this application have been running a little fan to spread hot air, or a small lightbulb or maybe electronic charger. Certainly not anything you would call "providing power" for a house.
One thing to really keep in mind if you decide to do this is paying attention to the hot versus cold side of the Stirling equation. From experience, I've had Stirling designed wood stove fans that work for a short period, but because the differential temperature cannot be maintained, stop working soon after they start running. The temp differential is KEY to Stirling performance: http://peswiki.com/images/0/0c/Stirling_engine_diagram.gif
