This relates to my post of September 9 [Fluidyne well pump (5m)]. I was
after a really simple solar-powered shallow well pump, and was fairly
pleased with that design.
But I just couldn't leave it alone - and wanted to simplify it still
more. After a lot of lost sleep, I decided that it should be possible to
eliminate about 2/3 of the plumbing /and/ about 2/3 of the fluid and
have a more efficient engine/pump combination.
What seems particularly interesting is that the new single-piston design
might open the door for a completely dry (no fluid at all) engine
capable of driving a single 'hard' piston for use with a linear
alternator - an exciting prospect for me since the 'classic' fluidyne
isn't particularly well-suited for generation of electrical power.
If you're interested, I've posted a new web page at
http://www.iedu.com/DeSoto/Projects/Stirling/5mPump2.html
with a drawing and rationale.
Feedback invited.
