Living in California has lots of perks; one of which is not having to clean ice and snow off your windshield. But for you poor bastards living in less temperate climates, here's the HotShot. The HotShot is a special heating chamber that warms up washer fluid as it goes through your car and out onto your windshield. It takes 45 seconds for the fluid to heat up to optimal temperature (145 degrees F) to clean the ice and gunk off your windshield.
There are some videos on the site (they don't work for us, unfortunately). Call their toll free number for pricing info.
