Solar Operated Automotive Window Exhaust Vent Suck Out The Bad Air! You say it&#39;s 235&#176; inside your parked Duesenberg in Phoenix? You say your kid&#39;s sippy cup melted while you were in the video store? You need this solar-powered car ventilator. Hook it over a window, power the window up and let the sun activate the solar panel and run the 3" dia fan, which sucks the hot air out of the car and vents it outside. The whole thing measures 6" wide x 4-3/4" x 2-3/8", with a slim 1/4" x 1" x 6" long piece outside the window. Includes 1" wide weather-stripping to seal it.
