My idea is to have sort of a scaled-down air conditioning system... most of my driving is city where I can just roll down the windows, but I live 5 hours away and drive home occasionally, and if its sunny I'd like to be able to use the ac. But also under ideal ac-use conditions, we also have ideal solar panel current. A single peltier junction (a small 2x2 in.) square draws 75 watts. If I can power a decent ac with 4 of them making a total draw of 300watts, would this be better than the belt-driven ac?
If the alt. is off then obviously, but since I'll probably need it on, so here's the question I'm looking to have answered: will an extra ~300watts of power use cause less load on the engine via alt. than a belt-driven ac?
