My mind was wandering the other day in class, just after our physics teacher showed us the railgun he and his class made a while back. Anyway, I was wonder if you could use this principle in starting a gasoline engine. If you wrapped the electromagnetic coil around a cylinder, and fired it like you fired the rail gun for a short burst just to get the piston moving to the top of the cylinder. As i was typing i realized that the one cylinder wouldn't always be at bdc when you shut the car off. There would really be nothing to gain, but maybe space and weight. Just chuckin out there for yah to think about.
