What are the odds that somone in the know might tell the rest of us (me) what a Peltier Chip actually is?

A peliter device is a string of diodes hooked together and oriented so that all the P sides of the diodes attach to one plate and all the N sides attache to the opposite plate. The heat is transferred from one side to the other by the motion of the majority carriers in the diodes.

I have used them many times to cool laser diodes and they are terribly inefficient. Without running the numbers I would expect that you would burn more gas powering these than running a standard AC.

As an engineer I find it insulting that the poster seems to think GM has not thought of this and run the numbers. These sound like some clever kids but their quote about gas usage makes it very clear they have no idea how to calculate efficiency.

How is Sherlock doing these days? I hope all is well.
