It's been around much longer than that. AFAICR it started with a pseudo-technical book of fiction written by an ex Jumbo pilot, that was adopted as a text book by groups of loonies all over the world. I was invited to a demonstration in Brisbane where I live, and explained to my wildly enthusiastic (but not so technical) friend that on the day there would be some reasonable explanation why it didn't quite meet its claims on the day of the demonstration, and sure enough, the "good" magnets were away being re-magnetized. With the "bad" magnets, the machine managed only 90% efficiency, but the "good" magnets had double the energy, so any fool could see that they would produce 180% efficiency (not me, of course, because I had been brainwashed by the traditionalist education system run by the oil companies to suppress all such breakthrough technology). Soon after that I heard that the person who put on the demonstration had sold his house, donated the proceeds to a consortium to develop the technology, and moved to New Zealand to be with them and share the dream.
