Cold fusion back in the spotlight
According to a recent article by Jeff Nesbit, cold fusion's is experiencing a new "burst of energy". Despite the horrible reputation it has in part thanks to that ridiculous film starring Val Kilmer and Jennifer Jason Leigh ... Nesbit argues that
"the hope that cold fusion somehow works and that clean, abundant, free energy might be just around the corner has been an alluring siren call for a few researchers working quietly in the past two decades. And now, it seems, some relatively interesting players seem at least willing to test the waters to finally determine whether cold fusion is real and can be modeled and tested properly with real equipment…or whether it's just a myth after all."

Rossi perfectly well knows all he has to do to convince the whole world he has something of great value is to use any of his "e-cats" to rapidly melt a plastic garbage pail full of crushed ice in public. The calorimetry is grade school science. Why do you suppose Rossi hasn't bothered to do that? It doesn't take a top scientist or engineer to weigh a few buckets of melt water on a bathrom scale (bring your own scale). High school physics students can do the math to figure the heat required to make the phase change from solid ice to liquid water. We can only conclude Rossi has no serious purposes of "proving" his e-cats work. So far Rossi is only selling hopes and dreams, not working e-cats. A prudent public should ignore the LENR hype from all quarters until someone is using it to melt hundreds of pounds of ice. It's a purely silly waste of time to speculate how a gadget might melt some ice, in the event it ever melted any ice. Let it melt some ice first, and then let's speculate about how it might have done it.

'If you're going to do something then do it right.'
That is what Rossi is doing. He's clearly not bothered about the rest of the world just yet. He has his supporters, and the funding he needs, and is now content to busy himself with perfecting his machine before he makes any grand unveilings. His previous demonstrations were merely to attract investors, nothing more.

Well, it seems Rossi has attracted enough "investors" to continue whatever it is he is doing. In the meantime developimg nations are investing $100s of billions into traditional fossil fuel power plants that should be considered obsolete and major polluters even before they are completed and come on line.
Are we to suppose Rossi is indifferent to the coming pollution and incredible pointless debt burden the children of those developing nations will inherit? If the developing nations’ energy policy makers had clear objective scientific proof that Rossi's E-Cats really work as claimed, they would put fossil power plant plans on hold, and wait a couple of years and then install more efficient and non-polluting Rossi power plants. So it would seem Rossi's version of "doing it right" includes indifference to increased pollution and wasting billions of sorely needed capital in the developing world.
Rossi is highly intelligent, and while he’s trickey, he is not evil. If he could clearly demonstrate to the developing world that their planed fossil fuel power plants are already technically obsolete wouldn't he do so? He is not doing so. Guess why?

Does anyone know what sort of funding Rossi has received to date?

It's a safe bet his wife knows. Much of his operation is in her name. Seems doubtful Rossi is personally keeping up with or worrying much over the chicken-feed money. He might have a legitimate logical attitude that since he has the most important and economically valuable technology ever discovered, all the money he needs for development and manufacturing will come from somewhere. He and his wife want to keep dilution of control and ownership to a minimum. To get more funding when his wife says "we can't afford to do that, go raise X-million" all he has to do is make a convincing demonstration to a person or institution with lots of money. That's supposing he can actually make that demonstration.
It has been more than a year since Rossi promised to start production of portable cold fusion devices. Nothing much has happened since. Anone who has read little bit more about cold fusion would be very doubtful about new and simple ways to create cold fusion. I bet, Rossi will never create any usable coldfusion device.
You may want to read this article...
... in which Aldo Proia, Ceo of Rossi's main financial backer, said the E-Cats running at low temps such as 120ºC are for sale now and the guarantee is for a co-efficient of power or COP, of 6.
I remain extremely skeptical about cold fusion. if I have just to believe what mr. Rossi says, it is not enough. And saying "150y ago doctors did not believe existance in germs" is not convincing. 100 years ago there were plenty of inventors of "perpetum mobile" due to general lack of knowledge of physics. They were secretive. Just like mr. Rossi is.
There are several fundamental problems with cold fusion:
Like lack of expected reaction products
Conventional deuteron fusion is a two-step process, in which an unstable high energy intermediary is formed:
D + D → 4He * + 24 MeV
Experiments have observed only three decay pathways for this excited-state nucleus, with the branching ratio showing the probability that any given intermediate follows a particular pathway. The products formed via these decay pathways are:
4He* → n + 3He + 3.3 MeV (ratio=50%)
4He* → p + 3H + 4.0 MeV (ratio=50%)
4He* → 4He + γ + 24 MeV (ratio=10−6)
Only about one in one million of the intermediaries decay along the third pathway, making its products comparatively rare when compared to the other paths. This result is consistent with the predictions of the Bohr model. If one watt ( 1 eV = 1.602 x 10−19 joule) of nuclear power were produced from deuteron fusion consistent with known branching ratios, the resulting neutron and tritium (3H) production would be easily measured. Some researchers reported detecting 4He but without the expected neutron or tritium production; such a result would require branching ratios strongly favouring the third pathway, with the actual rates of the first two pathways lower by at least five orders of magnitude than observations from other experiments, directly contradicting both theoretically predicted and observed branching probabilities. Those reports of 4He production did not include detection of gamma rays, which would require the third pathway to have been changed somehow so that gamma rays are no longer emitted.
So, if someone says that he has an invention contradicting known laws of physics and nuclear physics, and it is not possible to repeat the experiment with same results, I just do not believe. It is just another very classical "perpetum mobile" case.
Btw., discovery of Higgs boson was proved by two separate and independent experiments. Why mr. Rossi could not follow the same path? After patenting whatever he needs to.

Hey Guys, There is according to some an oil asset sell off by the major oil companies. Here's an interesting link.
Whatta ya think,
You will find some extremely interesting pieces at this website. Looks like Brillouin is coming on strong. Hang On
