I came across this today: http://www.exciters.com/0009/ecool_AFT1.htm Would it work in a Prius with its small regular battery? Not to mention the complicated computers controlling everything...
I wouldn't get it, you can just roll down the windows for a minute and then put them back up and it is cool.
Unless it's 115F outside in the desert... I wouldn't get it w/o a solar panel to power it though, the Prius 12V battery is pretty megar when it comes to longevity. I'd consider first the deal that fits into the window, and is a solar powered "fan" that keeps the car ventilated.
I have thought about those fans before, but here around OC it doesn't get that hot. We can do without it.
I received one of those as a birthday present. It is an "Autoveturbo", manufactured in the UK. It is helpful in the parked Prius, but at highway speeds it is too noisy for my tastes. I would use it for extended summer driving at lower speeds, however, so mine is not for sale. DAS, and Tochatihu, a 2001 with 59k miles, 46 mpg mostly driven in So Cal
