Say we have an insulated hot water reservoir, pre-heated by a joule heater
(used only to start the process), as the hot source, and ambient air as the
cold source. An average efficiency Sterling engine (efficiency=40%
conservatively, say 1000W heat in, 400W mechanical out) runs on those hot
and cold sources (2LoT not broken),
For whatever, I still do not get Vo mail authored by Michel Julian and a
few other refular posters, so I hope that I am referring to the correct
postter here.
[side note: no MIB - this all goes back to adding the "Vo" to the
subject line]
OK Michel - if we are going to invent straw men to immolate, let's at
least dress them in reality-clothes.
This Stirling of yours must be alien technology ??) ... the one you
mention as 40% efficient :
LOL... whoa! is that some kind of silver-plated joke?
Your "heated water reservoir" is at a kelvin temperature of little more
than 400, giving a Carnot "spread" of only 100 degrees. OK... 102
degrees if the electrolyte is cooled by 2 degrees K due to electrolysis.
Given the normal losses inherent in a Stitrling, this works out to
"efficiency= 15 % conservatively, say 1000W heat in, 150 W mechanical out"
In other words, the starting premise is so incorrect in reality, as to
slant the whole argument - but curiously I will say this - if anyone can
provide me with a Stirling engine which does, in fact, have a Carnot
efficiency = 40% conservatively, say 1000W heat in, 150 W mechanical
out" when operating on 400 degree K heat, then:
... Yes! I will absolutely guarantee you a self-powered system can be
based on such as system !!
