I can only imagine it was revealed for the scam that it was. Or else it wasn't revealed but still sank without a trace because it was just a scam. Whatever happened, it was a scam. It cannot work. I don't even need to know the details of this particular scam but I can say with absolute certainty that it was a scam. Aside from anything else, including the laws of physics and thermodynamics, if it actually worked in a provable fashion, it would be the biggest news in the whole of history, both past and future. It would mean pretty close to as much free energy for everyone as they wanted. Materials costs would drop through the floor.
