Idea for Turbine "almost Stirling" Heat engine.Pls comment.

Postby stuart1648 » Sat Mar 08, 2008 8:21 am

A newbie so pls bear with me.Idea: Cylinder of non-conductive material
(eg-plastic)with heat exchanger elements CLOSELY FITTED at both ends
and turbine (eg-fan) fitted into middle of cylinder . Hot Exchanger
draws air through small gap around it, heats it and expands it toward
fan; cold exchanger simultaneously draws the air from fan and expels
it through small gap around it.
In short a convective current is created which spins the centrally
located fan which produces electricity.
The gap size is crucial; must be small enough to allow pressure
gradient to build inside tube but large enough to allow flow-through.
It should be fairly easy to build feedback circuit to adjust gaps as
temperatures of exchangers change.I personally like geo-thermal for
delta h. Comments? Thanks, Stuart

A complete detailed description, with a diagram or drawing, if you can provide one, posted to the files /drawings will be necessary for anyone to comment on your proposed system.

The complete detailed description will avoid multiple post of replies asking for more details.

I'm working on a similar idea, have you taken any steps beyond your post? (like computer simulation, prototype, etc?)

Sounds like a description of a bootstrap engine is such there be.
A Stirling engine is a closed system with heat applied externally and rejected to the cold sink, with mechanical energy turning a flywheel or other means of mechanical connection to another device.

IF you depend on convetive circulation to generate power one of us is in the wrong business. Capice?
