Morris -
Its people like you who will give the common man "a leg up" on lowering
their energy bills. If i had money i would offer to fund your
experiments in a more formal setting, but. . . sorry, I'm just a working
stiff like most people.
Keep on keepin' on

I think I'll need to organize this stuff better than I've done so far -
but I went ahead and added two "orphan" pages...

There's a page at

http://www.iedu.com/DeSoto/Projects/Stirling/HTAbsorber/Angles.html

with a program that, given an absorption rate, approximates absorber
efficiencies for various interior angles. Please note that that a
displayed absorber efficiency of 100% will always be the result of
rounding a (lesser) calculated value to fit the format width.

Once you've picked an internal angle, there's a second page at

http://www.iedu.com/DeSoto/Projects/Stirling/HTAbsorber/Grooves.html

with another program that, given the groove interior angle and depth,
diameter of the collector tube, and the angular width of the target area
on the tube, calculates the values needed to actually produce such an
absorber.

For MS users I've provided links on both pages to MS-DOS executables. To
download, right click on the link and select "Save target as" - then run
the program in an MS-DOS window.

Linux users can compile the C source with gcc and run it in an xterm (or
whatever).

Everyone else is on their own. :)

Have fun!
