So what, that doesn't prove anything in the grand scheme of things.
Depending on where you live 20 acres of woodlot could be a bare
minimum to get you by for one household. It all depends on the size of
the trees, species and climate. A mismanaged 20 acres can run out of
wood pretty quickly if its garbage trees and underbrush.

I've been online posting for over 20 years, have yet to see any effect,
and dont expect to see any on the grand scheme of things in the years I
have left. I have, however, learned from the postings and benefited.
In this case, nobody tried a steam hybrid, so I'll keep looking into it.
As for my woods, they need to be thinned. Most of the canopy is 50 foot
now, and there's 3-4 times too many trees for the climax density.

If you mean one like that at the bottom of

you can burn sunshine. :)

That's cute, but Carnot says you'd need it hotter for enuf efficiency to
power a tractor or truck.

It's for stationary use. For more heat see
http://www.iedu.com/DeSoto/Projects/Stirling/Heat.html
If I'd used the mirror material crosswise instead of lengthwise, it'd
have produced the same amount of heat energy at somewhere near 1450F -
which would have required something a bit less "melty" than the cheap
Sched 40 PVC for the body.
(Theoretical) Carnot efficiency with a 1450F hot head and an 80F cold
head isn't too bad, but I doubt anyone would want to mount an adequately
sized trough on their tractor.
Might be fun to hear the tracker servos sing at the end of every row,
tho. :)
