It outputs more energy than you put in- by pulling energy from the magnets in it. Reading that article reminds me of reading the first short story in The Man Who Sold the Moon by Heinlein. In that, someone invented a lighting panel that worked just as well as a solar collector, and had insane efficiency.
This device works at 330% efficiency, without violating any laws of physics. I'm curious to know if the magents demagnatize through use in this device. It's heatless, noisless, and makes me horny.
And because he's not selling the rights to anyone, there's good odds that we won't see megacorps buying it and sitting on it to protect their establishments.
I honestly think that, assuming this is for real, this device could change the world. I want the miniature generator version that he's working on.
