The proof is in the pudding. Nobody argued with the Wright Brothers after they saw them actually flying their machines overhead. All these guys would have to do is set up a few devices in people's garages, disconnect from the grid, and demonstrate actually using the energy that is purportedly being generated.
Instead, all we get are YouTube videos of guys tightening screws or standing next to a humming machine. Why didn't the news interviewer ask the obvious question, "So then, are you running your house on this right now?" Unfortunately, I fear that the answer would have been, "Um, well, we can't actually do that yet..."
I want this to be true as much as the next guy, but it's easier to deceive yourself and others than to actually create a revolutionary technology. If you can do it, just do it and show us!
