the new plumbing at the turbine

I'm pretty eager to see it go, myself. Today I assembled, cleaned off
the shipping goo, and powered up a little mini-lathe from HF so I can
turn regenerators. I've never turned anything on a lathe before so this
should be "interesting". Obviously, I survived the power-up test. :)

Fluidynes are hateful because when you do see one in action, you can't
really see what's going on - only the displacement (or, too often, none)
at the output piston. The short video of the tiny engine on the web page at

    http://www.iedu.com/DeSoto/Projects/Stirling/Dyne.html

probably is the most (visibly) revealing, but the equations on the web
page at

    http://www.iedu.com/DeSoto/Projects/Stirling/StirlingCycle.html

do the best job of explaining what's really going on - almost all of
which (pressure, temperature, airflow, air viscosity) is invisible to
human eyes.

There's a page with a white paper written for Oak Ridge National Labs
that's worth skimming (so you can tell people "Oh yeah, I've read that")
and then forgetting because it's incomplete, misleading, and doesn't
answer the questions that would-be designers ask. It's been the starting
point for far too many abandoned eforts. :(

My most recent design was inspired by a non-fluidyne. :) Next time you
have a chance, take a look at this short YouTube video of a toy engine:

    

and imagine replacing the solid piston with a liquid piston. Pretty
fascinating stuff!
