here's the problem, adlep: if Rossi wanted to be taken seriously, he would have taken this to the normal route: peer review and journal publication, rather than holding a press conference for the media and the world-wide laymen (you) ahead of independent investigation.
It seems that he continues to reject independent investigation into his work. All of these habits are extremely suspicious and are very, very typical of fraudulent claims, or of a project that has failed--and he knows it--so he's getting the word out to the general public to generate interest, and hopefully some cash to recover loss.
If this does work and Rossi is serious about it--then he is absolutely doing himself no favors with the route he has taken.
It's weird that you only seem to focus on "scientific news" that reaches only the mainstream media, completely skipping the process of peer review. Such cases are almost always fraud, or simple Fud.
There's a lot more problems than those.
The big "public" demonstration that's got the OP so worked up was anything but public and I can all but guarantee the guy has not shown off what is actually happening to anyone that knows jack shit. Its not difficult to trick people, especially if you cherry pick who you do it to.
As already pointed out, they had a generator that they claim started the eCat system, which didn't work like claimed (output half of what it was supposed to, and happened to output just a bit below what the generator they had hooked up to it was likely producing).
Plus, he's claiming something totally new (which he's actually not, others have claimed the same stuff he is, just not exactly the same; none of those others were able to reproduce their claims let alone make them even function at a level that would make them be considered feasible) so that he can cover up not being able to actually show what is happening. There's just enough possible physics (vibrational energy from electrons in the lattice of the atoms electron cloud) involved that they can trick a lot of people while having an excuse for people who actually know much.
It wouldn't be difficult for him to have some other power generating methods that he could just cover up with a box. Then put a button that shows "self-sustain mode activated" and hey look here's the electrical readout. Its basically what Bloom Box did. He's banking on his customers not knowing jack shit and so he can sell a device that creates electricity to them and they won't know the difference and be generally happy. Very likely he'll require a ridiculous contract where no one is allowed to access it but him, but he'll probably throw in free "maintenance" which is him showing up every month to refill it with whatever fuel it needs (which he'll pass off as he has to keep checking up on it to gather data or something).
Watch, when he actually starts producing them, they'll cost a lot of money. They'll also take decades before their claimed energy generation will cover their cost (so that customers can't say that they didn't live up to the claims until much later). This way, he can make millions and sell the company before it collapses and he'll be set for life while his customers and company are screwed.
For allegedly being such a cheap energy source, it'll doubtlessly cost more than the usual sources of electricity do, but he'll make claims about it being greener or other BS so that he can "justify" the costs. Or they'll pass off how infrastructure for fossil fuels has made them far cheaper than they actually are and a bunch of other excuses.
In the end, it won't do anything of the things that "cold fusion" is supposed to do (ridiculously cheap, as in alone the costs would completely change the world; very clean; very efficient - doesn't need much material so we don't risk running out of whatever fuels the reaction; other aspects I'm forgetting). In short, this might actually work in some respect, but it won't be what people are thinking it is, and certainly will not live up to the hype of cold fusion.
In short, Rossi is pointing to enough actual science to make people wonder, but everything else he's doing just yells scam. Its not any different from the others, he's just doing a better job of obfuscating things so that you can't just easily dismiss him outright. He's clearly not in it for the science or to do what the OP seems to believe this will do (realize the potential of cold fusion), and that alone baffles me why the OP and others like him are so willing to believe.
