This post got me to wandering all day. I ended up at a Yahoo group on
solar AC. Had an interesting article that ties up everything we've
been talking about:

In short a turbine that is powered by lower temp ammonia steam that

steams the ammonia, and the residual cold can be used to cool
a space. Electricity and cold air! What a combo!
