Idea #2: Snowblowers Fueled By Snow

Its been snowing lately, and since we have a long driveway, everyone has to pitch in to clean up the driveway. A snowblower is the fastest way to clean our long driveway. Yet it runs on gasoline, a fossil fuel. What if snowblowers' fuel was snow? You could put snow into it, and it would turn that snow into energy to blow away other snow. All you do is add a little snow, and it blows away double what you put in.
