Not considering any of Rossi's technology - which he will never allow to be verified one way or the other - the most impressive and perhaps advanced player in this field that's moving towards commercialization is Brilliant Light Power via their utilization of the negative resistance regime to produce a massive rate enhancement of "hydrino" production. I'd go so far as to say that compared to Mizuno's system, Brilliant Light Power's Suncell is literally light years ahead with numerous advantages. For a company the size of Google with billions of dollars to spend, I can't help but think that a project composed of a series of experiments to investigate the potential of the complex space charge or "macro-EVO' that MUST form (this is in mainstream literature) during a negative resistance - to power the circuit while the voltage and current relationship is reversed - should be conducted.
Matt Trevithick has been part of the LENR community for some years now, and has participated in a number of ICCF's. He is very familiar with who, and what is out there. So certainly he is familiar with BLP. I doubt too many in his position would try and replicate the hydrino. If they did, there is the very real threat of being sued by Mills. You yourself should know that, from when you and gerold.s drew up that experiment, and we got the complaint it was going to make hydrino's if you operated it, and violate their patent.
