Anyone else remember the TAMs Model Airplane project from 2003? Similar idea as the Rutgers project, but they did it with a model airplane (and I'm guessing no where near the funding dollars that Rutgers has).

Just to clarify, internal combustion engines DO NOT run on explosions. They burn they're fuel at a very controlled rate. The fuel only explodes when there is a major problem with the timing of the engine or when using a low grade fuel in a high compression engine. And when it does explode (called detonation), it quickly destroys the crank shaft and connecting rod bearings and eventually the entire engine.
