One of the most disappointing things about cold winter days is all the ice you have to scrape off your car just to go to school/work/extra-curricular activities. Not only is this a pain for myself to do, but when I get on the road, I see many new, inexperienced drivers who are just too lazy to scrape more than two square centimeters off their windshield, which poses an immense safety risk to anyone driving.

In order to decrease the happening of this, I propose a heated ice scraper. It wouldn't be heated by electrical use, as I'm aware of the dangers that the melted ice would have when combined with electricity. Rather, an exothermic process referred to as "slaking lime" would be used to generate the needed warmth.

In the process of slaking lime, Calcium Carbonate (CaCO3) is superheated, which causes it to release CO2 and Calcium Oxide (CaO). Packets containing Calcium Oxide and its reactant, water, in separate sides of a plastic, non-reactant package. When someone wanted to add a quick boost of heat to their defrosting efforts, they would break the package, as one breaks a glowstick. This would produce Calcium Hydroxide (Ca(OH)2), as well as a useful amount of heat.

A chemical mixture used for cleaning ice from your car windows?

how does this differ from your standard de-icer?

Good idea, but we have to think about the transparency and the glass life of the wind shield also, while using those chemicals.
A proto type can be made and tested so that we shall be confident of the idea.

Why not just spray metholated spirits(ethanol) on the iced windows. Cheap and it evapourates very quickly. Just dont smoke while doing it..
