Hey, I have a 97 Civic EX that I've been working on lately, and I'm looking to do a few FE mods. I know that when running, the air conditioner sucks a lot of hp out of the engine, especially on a small car.

Would running a peltier cooler (or an array of) be more efficient than running the ac compressor? Here are some preliminary obseravtions:

Pros:
- less rotational energy needed from the belt
- less weight (how much does the entire ac system weigh? 100 lbs?)

cons:
- uses a lot of power. my guess is that you'd need 300-400watts of power, causing the alt. to raise resistance
- a lot of work to implement

Any thoughts?
