Alpha Sterling

Here is the current rendering of an alpha class Sterling engine. This is a "2 Pair" model. There are 2 hot cylinders and 2 cold cylinders. It also has an integrated water pump to cool the cold cylinders. The red and blue tubes will go to a radiator.The intent of this engine is to place it in a wood run firebox with secondary air jets pointed at the hot cylinders. This should take advantage of the "gasifier" effect and create a hotter localized burn of the CO and methane. The cylinders have a combined displacement of 20cc. As a wild guess I'm hoping to achieve about 200 watts of power at the output shaft. Seems a bit much for such little displacement but we will see.
