I am at my wits end. Honestly...I have been building Beta type

Stirling engines for the last four or so years since I was introduced

to them buy word of mouth.

Even thought my engines work rather well.. I STILL don't really

understand what is happening. What I do understand is that

temperature is different than heat. Heat can be seen as a fluid that

moves depending on the temperature differential..so far as it will

always try to find the nominal temperature from (so they tell me)low

pressure (or temp) to high!!! I have explored the internet to my max

capabilities for a good explaination, but all that I can come up with

(that makes sense to me) is my own idea (given my past learnings)that

Temperature correspongs to Volts (pressure) Currect corresponds to

heat (amount of STUFF-vibrational energy) and that anything that

comes between these two factors is resistance being the transferral

of heat (working fluid) trying to find it's nominal temperature

(being controlled buy whatever physics that says there has to be a

voltage potential - or difference at all ???)

I'm just really confused. However I am happy. My current engine is

made from one sheet of Aluminium folded into the chassis with slits

that direct the power and displacer rods from rotary to linear

motion. The displacer is a red bull can and the cylinder is an olive

can the crank and ajoining joints is simply No 8 wire. A tea light

candle will work my engine at 700rpm however I do not know the

efficiency as don't know how to calc input given degree celcius of

external source?? and how to measure that source given the

temperature that is dissipated throught ordinary atmosphere of

garage :o) ..So anyways if anybody could reply to this email would be

greatfully appreciated..

PS Even if I did know how to calc input,I am not sure of how to calc

output in watts (so as to calc eff) as I am a bit iffy about the mass

aspect ...so far as do I measure the crank as well as mech weight

then mult by the radius to get force (F=m.a) or just the crank weight

by its self.
