I do love gadgets, but about all the $20 gadget could do was spin the fan blade so you could say "ooh! see? It's working." You've got to assume that the overpriced one has much larger solar panels and enough air flow to actually be effective.How bout solar powered headlights? didn't american cars use to have some kind of auto vent system way back when? It was a little fan on a sun visor with a solar panel on it, so you left, flipped the visor into the window so it was towards the sun, and then it spun the fan and blew air from the window around the cabin. I think you can also buy something similar for about $20... $3600 is a little overpriced...
That's one of the cute little gadgets I was talking about. You get more cooling effect by just leaving one of the windows cracked a half inch... which is about how much you need to leave it open to shut the fan inside anyway. Instead of a 160 degree car, you get a 155 degree car if you're lucky.Plenty of aftermarket gadget that do the same thing.

I swear by my solar battery charger/topper offer.Solar stuff in small effects has never worked that well anyway.
Ooooh! Now what I'd like are electrochromatic windows. We had a limo come through once that had em - some sort of plastic film layered between the outer glass and the lexan inside. You could flip a switch and go between tinted windows and practically opaque.From what i've heard.... The $3600.00 is for the "solar package" and includes photochromatic windows. I suspect thats the majority of the $$$ Don't quote me though.
