Have a pellet stove with a Stirling Engine mounted into the burn pot, heat generates the combustion cycle, which turns a wheel, that spins a combustion blower and turns an auger, which feeds itself. Opening and closing a restriction plate in the hopper controls heat output. A separate low heat stirling mounted on the top with visible crankshaft control a convection blower in a total steam punk fashion.
Yup...I know it would work. No electricity required.
