You know, it's been quite a while since I was at University, so my memory of
exactly how a Sterling engine works is faded. But no, this does not
resemble a Sterling. This is not a modification of any existing engine.
Actually, its motion reminds me of a Scotch Yoke, but I was scolded for
that, because of Scotch Yoke is complex and inefficient and this is simple.
I am not a mechanic or engineer.

Yes, it's a two cycle four stroke engine. It IS inconsistent with current
technology, because it is new technology. We have a working model but not a
prototype yet.

Actually, when I first learned about this engine, the thing that stuck me
most was the simplicity of its motion. It struck me as being very simple
geometry. Did you get a feel from the patent what its motion is like? That
was what convinced me to get involved.
