[ausev] A/C in an EV

[Clendon Gibson]

Off and on I read articles about Sterling Engines. A sterling engine takes a temperature difference and turns it into mechanical motion. But you can also drive the sterling engine with a 12 motor or what have you and generate cold that way. Of course the sterling engine will also have a hot end.

There is a company that uses this method for cryogenic containment.

An alternative that may be more accessible to the home brewer is thermoacoustic refrigeration.

I saw these at a show http://arcticaircooler.com/ so I started making my
own.  The guy said he went thru eight designs before he got it to work
well.  I tried two different methods and one seems to work ok.  I never
quantified it in any way but I think it would certainly help reduce the
heat for a short while.  I think it's worth pursuing (and so did the guy
that made it a business.)  Btw, they start at over $400.
