This doesn't seem like much of a conundrum to me. It will either work consistently and repeatedly or it won't. I'm betting on the latter. If it does in fact appear to work the man is a fool if he believes that he will be able to keep his "flux capacitor" a secret. Even if he has actually invented something fantastic no government is going to allow him to be the sole keeper of what might be a world changing technology.
It would be fantastic if he had created this, it really would, but I figure my banana peel and coffee ground powered matter conversion system provides as much cold fusion as the E-Cat.
