Oh man, here we go again. If he achieves more power out than he puts in to cause the reaction and control it, the scientific community will just claim it does not work and ruin his career. Replication attempts will be made and whether it works or not, those attempts will be made to fail. That will be proof that it doesn't work, whether it does or not. It will also intimidate any honest groups who succeed at repeating his results from disputing the peer reviewers' claims that its all a fraud. Saw that trick not so long ago.
This guy had better do a full disclosure on the process, equipment used, full explanation of the reactions, blueprints & schematics, ect if he wants to be sure this does not get suppressed. Repeatable results by honest groups is the only chance this will ever see the light of day.
As for home units powering our homes, don't hold your breath. Either we will be hit with a mandatory tax, made into law, that requires everyone to give money the power companies, or it's use at the home level will be outlawed, for our own protection, of course. (I've seen this force-us-to-pay-a-private-industry trick somewhere recently, too. Let me recall where I saw that. Hmmm. Oh right, the new law that demands we must pay health insurance companies to screw up our healthcare system and murder us at will by denying treatment for life threatening illnesses when said treatment would reduce profitability.)
I wish him the best of luck, but I suspect we'll hear no more from him very suddenly if he gets too much closer to his goal.
