Hi Ken,

Well, 0.5-1.0Kw is perfect for what I want but I would like to able to build
the engine much cheaper than A$9000 odd. 15% wood to watts, particularly
Electrical watts would be great but I wonder how this would compare to a 1kw
impulse turbine rune a very high temps and pressures using a refrigerant gas
or at worst steam. Are there any plans for an economical to construct
Stirling engine?

I want to know like everyone else I guess what the best solution is.

Best, G
