You can find lots of thermoelectric power sources far cheaper than that, there are devices that will produce electricity for both cold and heat.

 

A basic TEC is reversible, it creates temperature differentials with current, it creates current from temperature differentials. Almost like a Stirling Engine for electricity instead of mechanical motion.
