Electric defrost/heater ?
I had a chance to try it out today and it's a winner. While 100 watts doesn't sound like much it puts out enough heat and fan speed to easily defrost a windshield.
The fan is super quiet. If installed under a dash I doubt you could even hear it run.
I'll start with one, but might end up using two of them just because they are cheap.
They raised the price significantly after I purchased this one on eBay. Now that makes them cheaper to buy on Amazon.
I had it over at my friends for show and tell this afternoon. He immediately bought two for his racecar.
