Hmm, where do I begin?
Burned off my head of hair in an instant, caused total meltdown on lawnmower motors, created sonic booms and intense pressure waves, and made some seriously powerful potato cannons. If you havent progressed past hairspray, you havent lived. . .
I actually had slight success at using the generator for supplementary fuel on automobiles, but it requires retarding the timing and water injection to keep things under control. A little hydrogen, goes a looonnnnngg way.
Now think about what you could do with it? Its lighter than air, has a ton of potential energy, and is found in a 2:1 ratio in the most abundant chemical on the earths surface, water. Its the perfect fuel, now figure out how to make it efficiently.
