Big Bonsai - Power and energy pour from this machine via a double overhead cam. This very well made German Stirling runs using the supplied burner. Just add methylated spirits (denatured alcohol), light and place under the Stirling engine. Wait a short while for engine to heat up and give the flywheel a flick. It will burst into life and get up to an impressive speed. You can then throttle the speed by sliding back the burner or removing. Product is supplied assembled.
