Ginger ("IT", "Segway") may have disappointed a lot of people, but at least it's a real product that's kind of cool from a kid's point of view.
I't's incredibly easy to set up a public demonstration of free energy. Happens all the time. A lot harder to get the device to work when an outsider tries to duplicate it.
One last thought. During the atomic spy trials, a lot of folks thought that the greatest secret of the atomic bomb was the fact that it COULD be built. Prior to its demonstration, a lot of folks thought there were too many practical difficulties. If anyone ever demonstrates that free energy is actually possible, there are tens of thousands of engineers capable of duplicating it.
But look at the key word in your statement. Duplicate.
I'm not saying I'm betting the farm on this guys invention, but rather I'm very hopeful that he HAS done it. Think of the possibilities.
