To be more specific Rossi now claims to be harvesting information density in the space time, matter waves from zitterbewegung, and zero point energy, to just name a few. Everything *except* LENR. He doesn't want to be associated with those crackpots.
Even more, he has finely tuned the Ecat to harvest information density from, specifically, the minds of skeptics. So if you guys feel words or thoughts escaping you, don't worry ; it's all for a good cause.
