"Lock in" Gasoline Rates Printer Friendly Version
Since gasoline rates seem to fluctuate more frequently than any other commodity, I think being able to "Lock In" to a rate for a given period of time, might be an attractive choice for many people. I'm not yet sure how the cost would be figured, but it would serve to provide some sort of insurance for higher gas prices. Perhaps it could be part of some sort of investment choice for stockholders of a particular oil company. Or, a way for non-stockholders to obtain something like a certificate of deposit for a specific company. The time period could be maybe three to six months. I, obviously, know very little about investing, but I think the idea could be developed in a way beneficial both to the oil companies and the buyer.

Heated Ice Scrapers Printer Friendly Version
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.

Save fuel Printer Friendly Version
Why not use the rotation of the wheels to power the cpu in a car and the air conditioning. Using the same technology that already exists in the creation of energy through water or wind turbines.
