There are lots of interesting articles on Anthony Watts' blog but when I saw the text by Ric Werme
Andrea Rossi’s E-cat fusion device on targetand noticed that it has a perfect, 5-star rating, I had to tell myself: holy cow! Do the skeptics really abandon 100% of their skepticism in order to believe this self-evident garbage? Is it just because there's not a lot of publicity about this "technology" (so far)? Well, it may change.
It's being claimed that you may buy a cold fusion power plant sometime next year. You will receive a simple low-energy gadget. It has some hydrogen and nickel in it, and some electricity. So it doesn't differ from an NiMH battery so much.Here a miracle occurs. You surely don't want to be annoyed by some technical details, do you? It's enough to trust the ingenious experts who invented - despite the disbelief of the physicists - a free energy source for you. Just for most technically inclined readers, here is the detailed engineering scheme of the new device:
A schematic diagram of the 2011 commercial perpetual motion cold fusion thermonuclear reactor.
And now, while emitting some - surely harmless - beta rays, neutrinos, and gamma rays, you have turned your nickel into copper (unfortunately not gold) while getting 1 megawatt of energy along the way. There's apparently nothing problematic about it and WUWT readers just vote that it is a 5 stars project. Well, it's plausible that the results wouldn't be much more sensible here but I still think that they would be at least slightly more sensible.
Werme's article contains no science - it's purely about marketing: it tries to answer questions "why should I care, what about me" etc. but never pays any attention how this could possibly work. You have to go to other sources to see what they're claiming to be achieving in their gadgets.
By a Google search, you may instantly find Journal of Nuclear Physics which is actually no journal of nuclear physics but a crackpot blog promoting this particular "fusion" (not to speak about similar crackpot theories of discrete spacetime - indeed, it does belong there, too). An even more official Free Energy Truth blog just announced the beginning of the World War III. :-)
One of the pages tries to answer the question how can 30% of nickel become copper (note that \(Ni,Cu\) have \(Z=28,29\), respectively) in those batteries. A good question, indeed. ;-) Well, the first reaction that should occur is
\[Ni_{58} + p \to Cu_{59} \]
By comparing the \(E=mc^2\) energies stored in the rest masses, you will may see that this produces about \(4 {\rm MeV}\) of energy. Nice and innocent. The lifetime of copper 58 is 118 seconds and then your healthy reactor is supposed to \(\beta^+\)-decay:
\[Cu_{59} \to Ni_{59}+\nu + e^+ \]
The positron annihilates with an electron to two gamma rays. Everyone is happy and your clean thermonuclear reactor may be used in your infant's bedroom. (This is of course also rubbish. Even if your substance were beta-decaying at this huge rate, it would produce lots of harmful ionizing radiation.)
An attempt to stabilize WUWT readers' brain
But wait a minute. Does it make any sense? Can the nuclei get close to each other for the fusion to occur? The proton and the initial nickel nucleus are positively charged, so they repel by the electrostatic (Coulomb) interaction. In fact, the maximum of the potential energy - when the distance is such that they nearly touch (but not quite, so that the attractive strong force is still essentially zero) - is a few \({\rm MeV}\) once again. You surely won't be able to subsidize the neutron - or the nickel nucleus - by your NiMH battery whose voltage is \(1.5\, {\rm V}\).
(It's not hard to see why the potential barrier is a few \({\rm MeV}\). The proton and the nucleus are roughly \(5,000+\) times closer than the proton and the electron in a hydrogen atom; the potential energy goes like \(1/r\). And the charge of the nucleus is \(Z=20\); the potential energy goes like \(Z\). So multiply these two numbers as well as \(10\,{eV}\) from the electrostatic energy in the hydrogen atom to get your estimate, \(5\,000\times 20\times 10\,{\rm eV} = 1\,{\rm MeV}\), for the electrostatic repulsive energy of the proton and the nucleus.)
Note that if a charged particle with charge \(+e\) - such as the proton - is accelerated in between the two poles of such a \(1.5\, {\rm V}\) battery, it will acquire energy \(1.5\, {\rm eV}\). You know, this is why the unit of energy is called an electronvolt: the unit is a product of an electron and a Volt. Because "mega" is "one million", you need millions of batteries to add up their voltages. You need to create a collider of this kind that will shoot the protons against the nickel nuclei. If it works, it will surely not resemble a NiMH battery.
If you want a proton to carry an extra kinetic energy of just \(1\,{\rm MeV}\), then \(\sqrt{1-\beta^2}\) has to be \(0.999\) which means that \(1-\beta^2\) is \(0.9995\) and \(\beta^2 = 0.0005\). It follows that the speed \(\beta\) is \(\sqrt{0.0005}=0.022\) times the speed of light - about seven thousand kilometers per second. That's the speed you would have to give to the protons (or the nickel nuclei!) for them to have a remote chance to get through the Coulomb barrier.
But the creative guys around Rossi have a solution. In the case that you're going to laugh out loud, be aware that the picture is not mine; it is taken from the pages promoting this stuff I linked above.

Picture via Journal of Nuclear Physics
You see that they "reject" a proton: a nucleus decides that a proton is a heretic who has to be excommunicated (I guess they meant "eject", but this is just the beginning). The angry proton borrows sunglasses from a carnival, masks himself to look like a neutron, and by this method borrowed from Agent 007 comfortably (and without any electrostatic repulsion) marches into the initial nickel atom, in order to revolutionize it and turn it into copper.
So Rossi's apparatus is mainly a device that produces these sunglasses for the proton and trains him to act as Agent 007. I mean James Bond.
Another page on the server tries to tell you additional details about the "probable" mechanism of the hydrogen/nickel cold fusion. (Note that they first managed to create a tabletop fusion reactor, and then they were looking how it's possible that they were so ingenious to guess it.) The page clarifies the training camp for the proton agents. How do they pretend to be neutrons? Well, they borrow an electron and produce a "mini-atom". That's just like an atom but it is as small as a nucleus. ;-)
Experienced TRF readers may recognize that at this moment, the cold fusion industry has incorporated another revolutionary discipline of physics, one about the hydrinos coined by Randell Mills who has earned tens of millions of dollars with this utterly stupid scam. The mini-atom cold fusion explanations are pretty much copied from his hydrino papers. Maybe these two groups even pay dividends to each other.
Quantum mechanics is evil, the uncertainty principle doesn't hold, and if you kindly ask the electrons to help you, their average distance from the proton may be 10,000 smaller than what they naturally like. If you carefully explain the electrons that they will help to make Mr Rossi quite some profit, the electrons won't hesitate and they will help to mask the protons so that they may pretend that they're neutrons.
Don't get me wrong. I find it plausible (yet unlikely) that a clever engineering setup will be found that will allow the protons in similar reactions to overcome the Coulomb barrier in the future, despite a "cold environment". Maybe a few protons will be exposed to some huge combined electromagnetic force from many electrons squeezed into a small volume. (Similar strategies exist in which laser beams are pushing the protons or nuclei.)
One by one, the protons will be fused, producing lots of energy. The only thing I am sure about is that these folks haven't managed to do anything of the sort. There is absolutely nothing nontrivial happening at the nuclear level in their devices. It's a NiMH battery claimed to become copper. Moreover, they claim that a nuclear transmutation of grams or kilograms of rather heavy elements is healthy enough for you to have it at home.
They have no idea what they're talking about and the actual mechanism behind their profits is that their customers are even more ignorant about basic physics than the authors of this "technology" themselves. Too bad to find out that this appraisal holds for most WUWT readers as well.
You can't turn macroscopic amounts of nickel into copper in a safe tabletop experiment. Fusion is physically doable but at least for a short period of time, the relevant nuclei simply have to have the energy corresponding to the temperature of millions of degrees. If you wish, the fusion reactor must inevitably "borrow" a huge energy comparable to the energy produced at the end. This follows from the shape of the potential. In this sense, the very term "cold fusion" is an oxymoron.
You can't get cold fusion, OK? This is just like the perpetuum mobile devices. Mr Rossi probably is a scammer but he may also be an honest re-discoverer of an NiMH battery: he just incorrectly measured how much energy such a battery may produce.
See Cbullitt for some fresh yet historical memories about cold fusion - and a nice compliment. ;-)
Wireless power transfer
By the way, if some people were observing some experiment where 50 cubic centimeters of a black box generated a very high amount of energy - kilowatthours - which can't occur chemically, well, then it is scam and there was either a secret extra conductor bringing extra energy or the energy was transmitted wirelessly. Some infrared radiation directed at the "reactor" would do.

Intel shows a light bulb shining in the air: the power is transmitted via electromagnetic waves, wirelessly. To transmit ordinary heat "wirelessly" is of course much easier.
I have made the same comment - either hidden wires or wireless power transmission - when I saw a video in which two burning candles power a light bulb or a motor etc.
I would never forget about the wireless possibility since ten years ago or so when I bought a rechargable toothbrush via ubid.com. The recharging occurs without any wires (which could be dangerous in a wet bathroom) - by electromagnetic waves.
It wasn't explained on the product so I was stunned - how it could recharge? :-) Of course, after some time - which wasn't limited, maybe hour, maybe even longer - I figured out what had to be going on. So then I could show the same trick e.g. to Prof Shiraz Minwalla who was equally shocked. How do the electrons get there through the plastic? :-)
Well, one doesn't need electrons to get through the plastic. One only needs the electrons behind the plastic to move and coils are enough to achieve it through the plastic. People, including smart and educated ones, may be easily fooled.
Algorithm of the scam
In the likely case that this is a scam and the people behind it know what they're doing, I guess that both the Greek and the U.S. companies are parts of the scam - they are meant to be the role models that lure other investors - other companies ready to produce this stuff and pay license fees.
The money for licenses will only come from other, new companies. The license contracts will be constructed in such a way that the dysfunction of the full engines won't make the contracts invalid. Moreover, I believe that the October deadline will be ignored and new "tight schedules" will be promoted to new investors without admitting that the previous ones were missed.












Currently it's 3.5 stars on WUWT so the the skeptics are downgrading it. I also found your comments, Lubos.
I don't know the physics well enough to comment on this stuff, but clearly you do and I've read many of your posts that are WAY over my head. I'm just one of the idiots who'd like to see something like this be real. However, reality intrudes...
So let's imagine that Bob comes to your lab and puts a black box on your table, small enough to actually fit on your table.
He claims that the box takes in input energy, say 220v, and outputs *way* more energy, for as long as you care to keep it plugged in. Let's say it's on an order of what Rossi is claiming.
What would be needed to prove to you, or any physicist, that the thing is real, with "massive excess energy" being output, and not a fancy battery, massive electrical hack, or otherwise a scam? I'm not saying this thing is real, I'm asking what would need to be done to prove that something like this IS real?
Thanks
Lubos,
Fascinating discussion, to which I would like to add a bit of nitpicking. In the paragraph that starts "It's not hard to see why...", your estimation of the number of eV in the potential barrier is off by a factor of 10: 5,000 x 20 x 10eV = 0.1 MeV, not 1 MeV as you stated.
Other than that, I can't really check your assumptions without spending a lot of Google time; I'm afraid that most of what I need to vremember about physics can be summed up in the statement "runs to red" (which describes the movement of negatively charged biomolecules in an electric field towards the red anode).
I've run into some of Rossi's devotees before; they sure made a fuss when I pointed out that there is no way Rossi could have invented a device that does what he claims without having a basic understanding of the mechanism involved.
Thanks for your kind words, Renee, but there is no numerical mistake in that paragraph.
Five thousand times twenty is equal to one hundred thousand.
One hundred thousand times ten electronvolts is one million electronvolts, i.e. one megaelectronvolt.
I agree such a thing is unlikely to be discovered "by accident". Combining some random ordinary materials and hoping that they will work as a perpetuum mobile is just not how physics may make progress.
You are correct. That just proves I shouldn't be trying to do math early in the morning.
