Here's what I don't get:
Why? Why would anyone make a claim unless they were 99.99999% sure of the probability of either being right, or of something else equally cool going on that can't be explained by the know parameters of the universe?
You end up looking like a complete idiot. If he's right, why all the wait? Patent your design, and put the specs up for others to duplicate. Or if it's supposedly dangerous and has military applications... I dunno, do something out in public where a lot of curious scientists will see and come help you figure out what's going on (unless you already know, in which case they will be most happy to be educated I'm sure -- well, if they aren't, then at least you know who not to listen to later, lol).
