I have read that a stirling engine could achieve as high as 30% efficiency in 
the real world. It seems that one could do that good with an IC engine if the 
same amount of money and engineering was applied.

I plan on building a Bisschop cycle engine:

-- No piston rings.

-- No tight piston to cylinder tolerance. Primitive machine shop.

-- No governor.

-- 110 rpm

-- No sticky intake valves.

-- Lots of heat for cogen (that's where I plan to make up my efficiency).

-- Maybe hard maple wood bearings (bio-bearings). Hey, it worked for Mercedes 
Benz.

-- The biggie, it needs NO crank case oil. It can not have oil in the 
cylinder. So how does it get cylinder oil? Answer: tar in the producer gas. 
Think of it as a two-cycle engine where the gasoline is mixed with oil. 
Someone built one and it would not run on propane, it needs producer-gas.

-- No spark plugs or distributor junk.

-- No fuel injection junk.

-- It faced the efficient Otto-cycle engine and still was vary popular because 
of it's simplicity and reliability. It was always a small engine. The 1/3rd 
HP was the most popular. They may have made a one HP. So Peter has me out 
powered and he doesn't need the extra by-product (heat) like I do so this 
engine is not for everbody.

Hint: It would make a great engine to turn an agglomerator and the off heat 
for drying the fireballs.
