I actually see what you are saying here. But the problem arises in 2 points. The first being you would need an actual way to harness the energy produced. This would be a challenge without interrupting the motion. The second problem arises when you consider the low amount of energy actually produced by doing such a thing. This would have to be done either on a much larger scale, or repeated over a large area. The chances of the success would be decent, but the chances of implementation would be extremely unlikely due to the fact that it is not a focused energy and does not produce enough energy to be of much use.

Well, there you have my opinion.
