<t>How much energy will you have to expend in order to achieve your goal?<br/> <br/> Consider a small glass of 100 cc to be cooled from 20 C to 0 C and then extract the heat of fusion of water from 50 cc to freeze that amount. Compare that to the amount of energy a normal human can exert as a first ...

<t>I have both an MM-5 & an MM-7. They run in the reverse direction when the bottom plate is placed on ice cubes. The MM-5 is also available in kit version. Follow assembly directions carefully.<br/> <br/> There should easily produce cooling when run by external power. If using an electric motor...

<t>May I suggest that you look at some of Dr. Izz/s material at: <br/> <br/> and the Second Law of Thermodynamics at: <br/> <br/> <br/> Also refer to the article on Sadi Carmot and "Towards the second law"<br/> <br/> <br/> <br/> A serious condideration of this material should clarify your thinking a...

<t>All thermal energy transferred to the hot end gas is either converted to mechanical energy (output) or rejected to the cooling water or atmosphere at the cold end.<br/> <br/> The Carnot efficiency is <or = 1 - Tcool/Thot where the temperatures are on the absolute scale. Actual value will be less ...

<t>The output energy level of the hot water output would not be sufficent to run a Stirling engine to generate any significant electrical power output. <br/> <br/> Such a Stirling engine would have to be designed for the energy supply conditions and again the small electrical output would not justif...

<t>Stirling coolers require mechanical energy input to produce low temperatures to liquify gasses for industrial and scientific purposes. They operate below ambient temperatures and are not suitable for use as conventional heat pumps.<br/> <br/> Converting large amounts of low grade waste heat and/o...

<t>You might find it worth your time to study the material posted at: <br/> <br/> <br/> <br/> This web resource is intended to be a totally self-contained learning resource in Engineering Thermodynamics, independent of any textbook. It is designed to be suitable for a two course sequence for Mechani...

Such a Stirling engine would cost far too much to be cost effective since there are no such engines generally available.

It is difficult to make a recommendation without more information as to the sizes of piston & cylinder etc. Metal rings increase friction and 'steal' power. "Vitron" might be suitable depending...
