I'm not sure; but think expired patents would be valuable in terms of
"prior art".

I hadn't (and probably wouldn't have) thought of that.

I did (two of them from you and a batch from other people). I've been
frying my circuits trying to absorb all the input!

Your second e-mail suggests that what I have may actually be a
steam/stirling hybrid, and I'm still working my way through what that
means in terms of modeling not-yet-built engines.

Several other people also suggested cold-side cooling, something I
hadn't concerned myself with, and I'm taking a look at low cost ways
to do that.

I was fairly comfortable watching the little desktop unit run; and now
I'm beginning to sympathize with the centipede asked to tell how he
walks with all those legs. :-)
