The Stirling engine does not have to work I just need reasons why it would be a good idea and then why it won't work, that will be showing that I have done research. I have looked at Stirling engines but as I don't know the average power output of a RMH. If there is only enough heat to warm the room and bench then that would be fine but it would be brilliant if I could get the battery bank charged with the heat given. Would there be any other bit of equipment I could use to change heat to electricity and that will be efficient??
Don't expect to be able to do both functions at once effectively with a stirling.
in this case you are trying to re-invent the wrong wheel. Go with the Rocket Stove. In case you need it go to rocketstoves.com to download a PDF copy of Ianto
Evans' great book, ' rocket mass heaters ' Tho $15.oo U.S., you will want it again when you and your Uncle decide to build one ! For your Rocket stove you will
need pages 76, and 77 , If you have committed yourself to building a mass heater type Rocket, Go to ernieanderica.info, pick out a model and tell your Uncle

The only way you would know for sure though, is to build it. In 18 weeks you should be able to build many test stoves. Use a large pot of water in place of the sterling engine. If you know the starting temperature and the end temperature of the water, you should be able to calculate the energy extracted from the stove and calculate theoretically how well it could power a sterling engine. The trick will be to see if you can get the stove to burn clean and still have enough draft to pull air through the whole system to heat up a mass after extracting all that energy at the point of the barrel.
Keep us posted on your results!
