Has anybody seen this item from IEEE Septrum on line ?
http://www.spectrum.ieee.org/WEBONLY.../0904nfus.html It seems to suggest that cold fusion is more than just poorly designed experiments Quote:

FWIW, I have a colleague who was a post doc at the U of U, and worked on the original F&P team. He swears all they had to do to get the neutron production count way-up was increase the temperature - which was very dangerous. This is of course anecdotal…but intriguing. My definition of good science is somewhat broader than Bob Parks: Any experiment, however bazaar (and that is not inhumane), but is well enough constrained to disprove or significantly challenge an axiomic scientific principle is good science. Screaming that they should have waited for peer review before going public is like telling the Wright Brothers your experiment has not been duplicated by an established avionics firm and is therefore invalid.

That's all fine Jerry, but P&F deserved every bit of vitriol that was sent their way. They were evasive, deceptive, and in the end wrong. They waffled when pressed for details of the experimental set up and never produced the results of the control experiments they claimed to have done after others asked them to. (Two come to mind, do you see excess heat with normal water?, is there helium in the electrodes?)
If it was so easy for them to produce neutrons all they had to do was arrange for proper shielding, place the cell into a neutron detection array, and run it hot. The claim that it was "too dangerous" is a red herring. There was no need to place anyone at danger to do the experiment. That they did not perform this sort of test makes me believe that they could not produce neutrons, your friend's story notwithstanding. Several other experiments did place cells into such a detection array (Moshe Gai's at Yale being the most sensitive). They saw no evidence for any neutron emission from the cell (and no excess heat either). Any new experiment not only has to show heat & neutrons, it needs to explain why experiments such as Gai's were flawed. Hopefully the DoE review is exploring just this sort track.

In fact, had Cold Fusion been real, isn't there a chance that THE MAN would have swooped down, and just by the skin of his teeth nipped this thing in the bud?! Wouldn't a true Cold Fusion discovery turn geopolitics on its head? Cause the collapse of the Middle Eastern economy? (Among many other economies?) Granted, in the long run, cheap power is a good thing for human productivity. But the short term economic and political upheaval of something like CF is almost unimaginable. I think there would be a lot of pressure to keep it under wraps. Am I wrong? boris PS and if P+F had any good reason to bypass the "accepted process," this one would have been it - to bypass THE MAN. If they really believed they were onto something, they also would have understood the global / political pressures. They would have known that more than mere science was at stake.

You are right that the implications would be huge, but I don't think something this big could be suppressed, especially given the openness of communication within the scientific community.
There are acceptable ways of distributing results prior to their acceptance in a peer-reviewed journal. Talks at conferences, publications in conference proceedings (some are peer-reviewed, most aren't), and most significantly, the Los Alamos preprint archive. Calling a press conference is not considered acceptable. Obviously, when this did happen, "THE MAN" didn't swoop down and nip it in the bud, or we wouldn't be having this conversation about it. |

I would be hard pressed call every CF event scientific quackery. It is also clear this process refuses to be tamed, and may never produce a useful watt of energy. But you and Russ are missing my point. Good scientific practice falls into two categories: Using the scientific method and known physical laws to set up experiments that increase the body of knowledge, and experimental results, however conceived, that change the rules. The first class - expanding the knowledge base generally requires the peer review process. The peer holds the test up against the body of scientific knowledge and says yes, it fits here. P&F were doing something that shouldn't work - they were out of there element - they made stunning observations that could not survive a peer review - they broke the laws, and now new ones are needed - something is needed to explain what is happening. The abhorance with which the physics community treats these events is very puzzling to me. If they were two clowns in a circus, I would still demand a reasonable scientific explanation, not "So what if they are levitating? They are just clowns." Incidently, the academic fraud they were accused of (in court) was a misplaced decimal - been there, done that.

My own work has examples of both. In one paper, we used our experimental system to physically realize a theoretical model and verify that the scenario the theory proposed could actually be seen. But in another paper of mine, we published results on an experimental finding that cannot be fit into the current theory at all; theorists in this area are trying to figure out how to fit our results in.

I followed this very closely at the time. I don't have a degree in physics, but I know a bit about conventional fusion. I was quite skeptical - but very hopeful. It wasn't too many years after "high temperature" superconductors had been demonstrated, and we hadn't expected them nor did we know how they worked. By the known rules, fusion is very hard, but I was hoping they had found a "trick." Obviously, if you could build a Mr. Fusion device, the sky is NOT the limit. I REALLY wanted it to be real.
But P&F made a fundamental mistake: They spread a story about "cold fusion" based on badly defined experiments. There are actually two directions the experiments could go: (1) demonstrate neutrons or fusion products regardless of energy production or (2) demonstrate excess heat substantially beyond what would be possible with a chemical process. All they needed was to have a clearly repeatable experiment that would properly demonstrate one of these things, then clearly describe it for others to duplicate. Peer review would come about eventually, but would be secondary to a good experiment. Instead, there were a lot of people all over the world trying to duplicate things based on the limited information that had been provided - meanwhile P&F went into hiding. And the duplicated experimental results weren't good, though there were a few that looked interesting but couldn't be repeated. Yes, there was publically stated resistance by some of the people in the field, but worldwide interest was huge. At this point, I don't think cold fusion is real, but the potential is great enough that I wouldn't mind seeing some official experimental review. They would need some VERY carefully done experiments to be convincing at this point, though. |

Why should there be excess neutrons? I'd want Helium.
If you take two Deuterium (2H) then each has 1 Proton and 1 Neutron. Fusing them in a Helium produces 4He made up of 2 Protons and 2 Neutrons. Last I heard 1 + 1 = 2 even with protons and neutrons, why should the reaction produce extra ones from thin air (or water as the case might be.) Evidence of Cold Fusion would be Heat and Helium. If Helium is being produced you -MUST- have fusion, there is NO other way to make it from Deuterium (or anything else.) As to the science community's reaction towards those that still study this field, it is -WAY- out of line. Sure P&F do deserve to be treated with a lot of caution (the vitriol they are treated with is just childish people) but there are many others who are treating the subject with complete scientific process and trying to see if they really can get results, yet they are being treated as pariahs as well. This is a very closed minded attitude and as highly unscientific as the community claims that P&F originally were. Even if you don't believe it is real, or ever possible, that doesn't give you the right to vilify those that think it could be.

[quote="chiaroscuro25"] 'Extraordinary claims require extraordinary evidence'. [/qoute] The days of extraordinary evidence are over - The Hubble ultra deep field? Extraordinary! Galaxies near the 'edge of time' that look just like they do today. But not earth shaking enough to dislodge a theory cast in stone. Most of the evidence that the Big Bang has failed is found in the subtle trends, the rise times in supernova, the Butcher Oemler effect, the Baldwin effect, the pieces of the puzzle that almost fit, but not quite. [quote="chiaroscuro25"] (In your Wright Brothers analogy above, it would be like they claimed to have a flying machine but refused to demonstrate it in front of witnesses.) [/qoute] Again, the university was calling the shots and put the sock in their mouths. But even if they were complete clowns, we still need a good explanation. If two clowns are levitating, we wouldn't expect them to explain it, but a good physcist should. All I ever hear is P&F were bad physicists. So was Madam Curie, but she was a damn good chemist. Utah was rained with enough fallout during the fifties to mutate a good Democratic state into a self-righteous Repulican one- maybe their is something in the soil. Maybe if you have to line up deuterium and wait for a cosmic ray. Maybe if we stuck an Fleshman jar in the path of a CERN ion all hell would break loose. But we will never know if we don't try.

Many teams have now duplicated there efforts. They report such things as the paladium cannot be too pure, the platinum too brittle. That P&F did not know how to constrain and reproduce their results is perfectly understandable: They did not have any theoretical roots to work with. We still don't know if it was a breakthrough, a mistake, or a known physical process in an unusual environment. Why?

Like I said before, where the physics community went wrong is not enough of them gave interviews saying it was impossible. P&F got pretty much the whole physics community to drop what they were doing and try to emulate their experiments. They held conferences with the American Physical Society and other professional bodies. P&F did not rate such high profile attention - they didn't earn it because they never showed anyone anything worthy of that level of attention. |

Claiming you have done something when you haven't is a lie and using that lie for profit (whether financial or professional) is fraud. Claiming that your device not only produces fusion but also suppresses the evidence (neutrons) isn't quite a lie, but it is dishonest and profiting from that deception is still fraud. Announcing results without conducting a control test is bad form (and a red-flag for those who spoke against them immediatly after the announcement). Doing the control test later, saying "we didn't get the baseline we expected," (and never actually releasing the results) then still claiming you have fusion (and, of course, profiting from that) is fraud. Jerry, you need to read-up more on what those guys actually did. |

An apparent effect where you "don't know how to constrain or reproduce" the results may suggest further experiments, but isn't enough to announce results. On conventional D+D reactions - about half the time you get Tritium and a proton, the other half Helium 3 and a neutron. VERY rarely you get Helium 4 and a gamma. In any event, you would expect some high energy particles from the reactions - which are not being seen. |

[quote="Van Rijn"]
If you can't reproduce an experiment, you have nothing to report. Theory is irrelevent. If somebody had conclusively demonstrated excess heat beyond what a non-nuclear process could allow or conclusively demonstrated fusion products, we wouldn't be arguing about this now. An apparent effect where you "don't know how to constrain or reproduce" the results may suggest further experiments, but isn't enough to announce results. [quote] Quote:
Whatever mistakes P&F made, and they made many, the mainstream physics community made a bigger one by screaming about the lack of theoretical roots while denying the observational facts staring us in the face. Something is happening that no one can explain. Deal with it.

It is imperative military research labs investigate claims of ‘new science’ and every possible avenue of military advantage. It can be argued England did not fall because they were literally one wavelength ahead of Germany in radar and direction finding technology. To many-perhaps most- American physicists, the pursuit of the atom bomb was as ridiculous of a venture as cold fusion. We still do not know everything. However, a recommendation to seek continued and expanded funding on one of these crank projects is very noteworthy – especially when there are so many agencies competing for these funds. The principle investigators know that their reports and methodologies will be scrutinized to the last decimal, and if they have been even one hundredth as cavalier as P&F, they can kiss their sweet research lab positions good bye. (I call this ‘argument by career staking rationality’.) FWIW, I am not convinced the phenomena are nuclear, but I would like to see a chemical explanation for the heat generation. This has been duplicated enough times to require a reasonable explanation. Once platinum/paladium has been saturated with hydrogen, does it diffuse out naturally or does it have to be heated? If some of these experimenters are starting with partially saturated platinum, the calorie count does not have to balance. Could these be ‘fuel cell like’ events? Anyone working with electrolysis ever have a pair of electrodes turn on you and start dumping out energy?

The military has enough pressing needs that it can't afford to waste money pursuing "every avenue," especially on long shot, marginal science. It needs to prioritize and investigate those that have a solid basis in science and that will have a large payoff. One could argue that one of the reasons the Germans were a wavelength behind was because they wasted effort on marginal projects like the V-3 gun, huge seige cannon, etc. instead of focusing on the more prominsing technologies like jet propulsion and getting those into production sooner.

One thing's for sure - the DOE report will not make the true believers say, "Dang, I guess it's not fusion after all."
Jerry, just because the government tosses money at it, it doesn't have to be sound science, or even make any sense at all. How many millions were spent on remote viewing, for crying out loud? How much money is wasted resurrecting Roswell? Look at the millions spent on the National Center for Complementary and Alternative Medicine, which endorses everything from therapies with restricted usefulness (like accupuncture) to blatant nonsense like therapeutic touch and homeopathy? No, tax $ being spent on it* does not mean there's something to it. Just that somebody who can sign a budget thinks there might be. *Nor does the latest slobbering cover of Popular Mechanics. |

Yeah, that would be most certainly the case. And, of course, I should add the disclaimer to my original statement: "... presuming the DOE report is not favorable to CF." Which I am sure will be the case, although it would be awfully fun if we (the majority) were wrong and something wacky was actually happening.
