Stirling Heat differential Summary of Links
Hi Stirling Enthuisists.
I have been looking at the many links on Heat differential, and
thought is nice to centralise them in one place via a set of links
Sizing
a Stirling engine
Temperature
differential to power ratio
3-5
kw Stirling for solar application
Article
Temp.
differential sources

Our thanks to Craig for ferreting out the links in his post for easy access to the information referenced.

FYI a question I posed to a Stirling Engineer.
Hi there,
As experts in your field, I would like to ask your opinion on the
viability of the following:
A Stirling Engine that is powered by decomposing Organic waste, of
which heat differential is between 20-40 d C.
http://www.css.cornell.edu/compost/moni ... rtemp.html
http://www.stirlingengine.com/bboard/q- ... ng+engines
I was thinking a small Stirling engine could produce some power from
this differential, but the amount I don't know?
Do you think this is a viable idea? What sort of power output would
the system have?
I look forward to your reply.
Regards
Craig

Mr. Lambie,
The merit test should be done on a pure thermodynamic concepts, even without the Stirling in mind. As such, 20C to 40C difference is very very low to operate a machine, any machine. If it can be made to run (???) it will probably be extremely big and inefficient for the amount of power produced.

It is like Sunpower stated. Don't expect much from a 40 to 50 deg. C temperature differential. Maybe just enough to run the engine at no load. Take the time to read through some of the previous threads to get a better sense of what is involved.
