Physicist Claims First Real Demonstration of Cold Fusion
by Lisa Zyga
On May 22, researchers at Osaka University presented the first demonstration of cold fusion since an unsuccessful attempt in 1989 that has clouded the field to this day.
To many people, cold fusion sounds too good to be true. The idea is that, by creating nuclear fusion at room temperature, researchers can generate a nearly unlimited source of power that uses water as fuel and produces almost zero waste. Essentially, cold fusion would make oil obsolete.
However, many experts debate whether money should be spent on cold fusion research or applied to more realistic alternative energy solutions. For decades, researchers around the world have been simply trying to show that cold fusion is indeed possible, but they´ve yet to take that important first step.
Now, esteemed Physics Professor Yoshiaki Arata of Osaka University in Japan claims to have made the first successful demonstration of cold fusion. Last Thursday, May 22, Arata and his colleague Yue-Chang Zhang of Shianghai Jiotong University presented the cold fusion demonstration to 60 onlookers, including other physicists, as well as reporters from six major newspapers and two TV studios. If Arata and Zhang´s demonstration is real, it could lead to a future of new, clean, and cheap energy generation.
In their experiment, the physicists forced deuterium gas into a cell containing a mixture of palladium and zirconium oxide, which absorbed the deuterium to produce a dense "pynco" deuterium. In this dense state, the deuterium nuclei from different atoms were so close together that they fused to produce helium nuclei.
Evidence for the occurrence of this fusion came from measuring the temperature inside the cell. When Arata first injected the deuterium gas, the temperature rose to about 70° C (158° F), which Arata explained was due to nuclear and chemical reactions. When he turned the gas off, the temperature inside the cell remained warmer than the cell wall for 50 hours, which Arata said was an effect of nuclear fusion.
While Arata´s demonstration looked promising to his audience, the real test is still to come: duplication. Many scientists and others are now recalling the infamous 1989 demonstration by Martin Fleischmann and Stanley Pons, who claimed to produce controlled nuclear fusion in a glass jar at room temperature. However, no one - including Fleischmann and Pons - could duplicate the experiment, leading many people to consider cold fusion a pseudoscience to this day.
But one witness at the recent demonstration, physicist Akito Takahashi of Osaka University, thought that the experiment should be able to be repeated.
"Arata and Zhang demonstrated very successfully the generation of continuous excess energy [heat] from ZrO2-nano-Pd sample powders under D2 gas charging and generation of helium-4," Takahashi told New Energy Times. "The demonstrated live data looked just like data they reported in their published papers [J. High Temp. Soc. Jpn, Feb. and March issues, 2008]. This demonstration showed that the method is highly reproducible."
In addition, researchers will have to repeat the experiment with larger amounts of the palladium and zirconium oxide mixture in order to generate larger quantities of energy.

I recall that when Pons and Fleischmann were doing this, there were a number of physicists who said the real proof would be to demonstrate the high-energy particles that should be the product of fusion (high energy neutrons I think-- not sure without looking it up, this is not my field). But this could not be demonstrated. Some were even saying that the most definitive proof that it was not really fusion was the fact that the researchers (and witnesses) never suffered radiation sickness.As my wife said back then, it is nice to fantasize about this, for a few moments; but it is highly unlikely to come to anything.

I would find it far easier to trust a Japanese on this matter. The concept of personal reputation actually has meaning for the Japanese people. I don't see this demonstrated quite as deeply in other cultures and it is nearly absent in the US.However useful Professor Arata's science is, the energy source we need is already available and we have plenty of technology to use it. Wind and Sun are here, right now, and cheap. What we need is a political system in the US much like that of Europe where the solar industry is going gangbusters. Good government helps. Government that hates its citizens such as here in the States is a no-win deal.

Actually, since Pons and Fleischmann, a lot has happened in this field.There is a small, but active, community of scientists working in the field now. They are avoiding the term "cold fusion" and use the term LENR - low energy nuclear reactions.
Research is being done in the US, Italy, France, Japan, Russia among other countries.
Budgets are small, but there is a rising interest.

Exactly. Fusion always gives radiation in the form of neutrons. Everyone in the room would have been killed. Why were'nt radiation detectors set up to verify the presense of radiation? A rise in temperature signifies nothing. A chemical reaction and a well insulated container could do the same thing.

As a nuclear physicist I have to correct some of the above misunderstandings : Fusion is NOT always accompanied by neutrons - that depends entirely on which reaction is going on. In the reaction claimed to happen in this story two deuterons fuse to helium-4 and nothing else. Each deuteron has one proton and one neutron, while the helium-4 has two protons and two neutrons. In the fusion reaction planned for hot fusion in the future fusion reactors the reaction is between deuterons and tritons leading to a helium-4 and a neutron. Secondly, even if neutrons had been present that would not directly have the consequence that people in the room would die - for that the dose rate has to be very high.Other Comments by fynbo

gas prices are cutting into my budget big time!
With the stranglehold that oil companies have on the world economy, you really think they would let cheap, easy energy leak onto the market? I expect to see this new technology crushed and derided on every front, especially in the US where petro-dollars fund appear to fund just about every political maneuvre.
Incidentally, next time you worry about the price of gas, consider that the current UK prices are £1.20 per litre for unleaded and about £1.30 per litre or more for diesel. Filling an average small car costs around £50, saloon around £100, and haulage firms are spending about £1k per week per truck on fuel....

Thats as maybe, but does it get "clogged up" with the stable He4? Remember this is generated within the matrix of the material. Can the He4 ALL successfully escape? If not the process is possibly useless.

Well, I hope this turns out to work (like everyone else pretty much).I'm not a physicist,but doesn't using heavy hydrogen (Deuterium) which is relatively rare make this process more expensive? I mean you can't just pick the heave hydrogen out of a glass of water like the regular stuff, you need to distill it out of 6500 glasses of water (no I'm not that smart. I wikied it). Couldn't that be tricky?
If it will prove not to be tricky (or a trick) than cold fusion will change the world immensely. Just to pick one aspect, it will make all forms of transport cheaper. This includes space travel. We've been stuck "on the edge" of space for decades now. The costs of sending a craft there that can support, protect and bring back home a human crew are enormous. Being able to carry large amounts of energy in a bucket may just prove to be the technology required to advance human expansion beyond this planet (and the way things are going on this planet, this be a pretty good idea).
It sounds too good to be true though, and I'm afraid it prbably is.

28. Comment #187763 by Ubiquitous Che on June 2, 2008 at 2:51 pm
I've seen a lot of optimistic skepticism regarding whether or not the demonstration was legit. That's as may be - I'm a software developer, not a physicist.However, I've also seen a lot of comments along the lines of "Big Oil will crush this tech boo-hoo" going on... And I personally doubt it.
My understanding of the oil thing is that our planet is operating under something very similar to Frank Herbert's 'Law of the Minimum', because the main thing that is currently holding back the growth of the economies in developed countries is the fuel source - oil - and this fuel source is *mostly* controlled by a very small number of people.
So would the owners of the oil companies try to crush this new technology? Most probably.
However, the owners of the oil companies are only wealthy and powerful because governments make them so - and it is very much in the best interests of those governments to get this new fuel technology for themselves.
American politicians can be pretty dumb - but I don't think that even American politicians are inept enough to risk staying on the petroleum standard when China could get hold of cold fusion, and vice versa.
I'm also very much in favor of undercutting the basis of the Saudi wealth that has been funding extremist Islam. If you want to kill wolves, trap rabbits.

1) Energy gain inferred only.
2) No account of sustainability or consumption of Palladium.
3) Arata is something of a Japanese nationalist.
Having been warned elsewhere about ad homs, I nervously include 3 as a bit of peripheral evidence regarding a motivation for wish-thinking on Arata's part. (Glorious Japan will prevail against its enemies!)

If cold fusion were possible, then the middle east could use the energy to desalinate ocean water, and could open up land for agriculture. So they wouldn't be that devastated.

An energy source is as valuable as its EROEI (Energy Return On Energy Invested). There is no such thing as a free meal. You have to invest energy to produce energy.To produce oil we invest on average right now 1 BOE (Barrel of Oil Equivalent) per 10 barrels of oil. 80 years ago the ratio was close to 1 to 100. The attractiveness of oil comes from the fact that it's a very concentrated source of energy under high pressure. You only need to puncture the oil chamber and it will gush out, almost for free.
Hydrogen is not an energy source. It will never be. It is an energy carrier. There is no free hydrogen on earth. Most of it is already burnt (spent) in the guise of water. The rest is combined with carbon to form hydrocarbon. The most common and efficient is natural gas which is on the same path as oil, meaning on its way out.
To obtain hydrogen, one must expend a lot of energy to dissociate H2O into H2 and O2.
Also, to produce fusion we need deuterium or heavy hydrogen which is present in the water in an average ratio of 1 atom of deuterium to 6500 atoms of hydrogen.
Even if the cold fusion announced by professor Arata turns out to be true, which I highly doubt, what will be the final EROEI of the entire process?
That is the important question of any alternative energy source. Without an energy source at least as efficient as oil we cannot sustain the present level of economic activity. Forget about economic growth.

The article hinted at the important words for me... repeatabilityWhile Arata's demonstration looked promising to his audience, the real test is still to come: duplication.
If it can be repeated, then we can be interested... then the next question arises - is it any use for the production of heat for the generation of electricity?
In addition, researchers will have to repeat the experiment with larger amounts of the palladium and zirconium oxide mixture in order to generate larger quantities of energy.
So the story was a reasonable one... build up the hope of the readers and the lovers of Sci-Fi (like me) but gave just enough information to keep our feet firmly on the ground. Lets be sceptical boys and girls. More testing required.
If I was a betting man, I know where I would place my money... but when it comes to science, I much rather keep my money safe and wait until the results are in.
Oh, the next question should be - how much does it cost to make ZrO2-nano-Pd (whatever that is?)

Just three major scandals of the last couple of years from Japan - and everyone involved had personal reputation at stake.
Are you trying to say that Western scientists are less trustworthy than their Asian colleagues?
Before a scientist publishes their work it comes under close peer-reviewed scrutiny. If false data is used it cannot be repeated and so pretty soon they get caught out. Remember the (oh-so honourable) Korean cloning scientist?
As a general point to this discussion I must ask this:
Why should anyone BELIEVE that these scientists claims are true? The experiments will quickly be attempted by others in the field and either validated or rejected. There is no believing about it. There is only one salient point - proof!!!
That's why this website is so important. Demand proof not faith.

Yes, cold fusion is heating up again. Check out this article from New Scientist last year.I have been checking on this from time to time over the last 19 years, and repeatability has always been the problem, in fact, unrepeatability is what has been repeatable. Again and again reputable scientists have seen something happen when enough deuterium is loaded into palladium, but cannot say exactly what, or reliably make it happen again.
But at the same time, it does not go away. Because palladium acts like a super sponge for hydrogen, it continues to be investigated for hydrogen storage and electrodes in fuel cells. We know from these studies that microscopic flaws in the surfaces impact the amount of hydrogen (or deuterium) that gets loaded into the metal. It is possible that the lack of repeatability may be related to the lack of atomically identical electrodes. If this is the case, and the nano coated pellets used by Arata are close enough to identical, then perhaps he and his team will be able to show it on a repeatable basis.
One thing is for sure, they would not make this claim and demo if they were not sure, themselves, because the history of this is so completely littered with the broken careers of scientists who could not repeat it. Skyhook is correct; we have to wait for independent confirmation. However, this is the fist time I think I will wait before betting against them.

Sorry everyone : it seems I was somewhat too fast in my little physics lesson earlier :-{Indeed there is a large probability that neutrons (and helium-3) are emitted in the fusion of two deuterons. The reaction I described is more rare.
I in any case doubt this is really fusion since I have not seen an explanation of what should bring the two deuterons close enough to each other for fusion to happen with large enough probability. In the sun the reaction is extremely rare, but enough energy is generated due to the large amount of material.

Precisely! And those stupid Evolutionists - don't they realise that also, The Laws of Thermodynamics actually prevent evolution on earth, because the system can't go from being chaotic to ordered without power input. I don't see any massive external power sources, do you?
Sadly enough, I've actually seen a creationist say something very similar to this...

Interesting article.To my mind, journalists and commentators are making the same mistake as in the Fleischmann case.
In order for the scientific community to keep objective about whether an effect is real, reproducible etc, the first step is to stop banging on about the important future applications!
