Cold Fusion is a suppressed technology

One cold weekend in the fall of 1985, professor Stanley Pons of the University of Utah asked one of his undergraduate students to look in on an experiment that he and professor Martin Fleischmann had been conducting in their spare time.

For two years, they had been running electric current through tiny metal cubes in a set-up that was a lot like a battery charger. The metal was an exotic element called palladium, and the electrodes were bathed in “heavy water” — i.e., water made from deuterium, the version of hydrogen that has a neutron along with the proton in the atom’s nucleus.

The experiments were a shot in the dark. Fleischmann had heard rumors from several colleagues that these cells got hotter than they should, so the two had left these cells running continuously for two years, with just enough hint that something unusual was going on to keep them trying different variations, much as Thomas Edison had a little over a century before in his development of a practical incandescent light bulb.

Out of town for the weekend, Pons got a panicked phone call from his student. The glassware was shattered; the lab table had been destroyed; and there was a hole in the concrete floor of the laboratory, where the experiment seemed to have melted through.

Both professors rushed home and met in the lab. They became convinced in that moment that “cold fusion” is real. There is no chemical reaction in the world that could generate that kind of damage from a tiny chip of metal, 1/16 of a cubic inch. It had to be nuclear.

Still, the scientists agreed to make no announcement until they had solid data for the anticipated critics. Pons was chair of the Utah chemistry department, and Fleischmann was a world leader in the little-known field of electrochemistry. Their reputations were solid, but not such as to support an announcement that exploded a major scientific paradigm.

How Unexpected Is Cold Fusion?

Fusion itself was not controversial. It had been recognized since the 1940s, and an international arms race in thermonuclear bombs made it clear that hydrogen could be turned into helium with a monstrous release of energy. But hydrogen nuclei put up quite a resistance if you try to get them close enough together to fuse. Fusing two hydrogen nuclei yields a net output of 24 million volts, but only after you put in 4 million volts as an initial investment, like priming a pump. (See my prequel on WhoWhatWhy.) The only known ways to get hydrogen to fuse were either to ram two nuclei together in a particle accelerator at about 10 percent of the speed of light or, equivalently, to heat the hydrogen to a billion degrees inside a bomb.

Fleischmann and Pons had their epiphany in 1985, but they waited and carefully collected lab data for almost four more years before offering an announcement to the scientific world. They had some sense of the skepticism with which their report would be received, but they were unprepared for the insults and venom that were spewed at them. This announcement would end their careers.

Fusion at room temperature? It does not violate any known laws of physics. For example, it could be understood within Einstein’s framework, E=mc^2. But it was highly unexpected, even given what was known about the weirdness of quantum mechanics. The problem is that initial 4 million volt investment. Physicists couldn’t imagine where that energy could come from.

Three Weird Things About the Quantum World

ONE — Identical Particles
If two ball bearings come from the same manufacturing process, you expect them to weigh the same, have the same hardness, bounce the same height… but they don’t talk to each other. In quantum mechanics, identical particles are responsive to each other’s presence, even when they are far apart.

This can happen in two opposite ways. Fermions — physicists’ name for the basic subatomic particles including protons, electrons, and neutrons — are “antisocial” in that they will shun each other. This is the deep reason that rocks are hard, and solids and even liquids are practically incompressible. Each electron in “condensed matter” (meaning solid or liquid) marks out its own territory and woe be to any other electron that tries to encroach.

The opposite of a fermion is a boson, and bosons are hypersocial: “Whatever he’s doing, I want to be doing it, too!” And if there’s a party, every boson in town wants to be there.

Lasers are possible because light is made of a type of boson called “photons.” Once you get a lot of photons all marching in step in exactly the same direction, there’s an irresistible pull for the next light particle to join the procession. Another example is superconductivity, in which electrons can flow through a (very cold) wire without any voltage to push them.

If you are interested in a little more detail about bosons and fermions and how quantum physics of identical particles is fundamentally different from an intuitive notion of what it means to be identical, I wrote about this subject last summer.

Yes, electrons are fermions, but sometimes, under rare circumstances and at low temperatures, pairs of electrons can coordinate to act like a single boson. This was not anything that physicists predicted, but superconductivity was observed in laboratories, and three quantum theorists came together to explain it: John Bardeen, Leon Cooper, and John Schrieffer shared a Nobel Prize in 1972.

Relevance: Heavy hydrogen is a boson. Perhaps all the hydrogen nuclei in the cube of palladium were acting in concert and doing something that none of them could do separately. Each separate nucleus was far short of the 4 million volts needed to initiate fusion, but if somehow they could pool their energy, there would be plenty.

TWO — Quantum Tunneling
Think of the way a siphon can suck water up and over an obstacle, so long as the tube has an outlet on the other side of the obstacle that’s lower than the water level in the inlet. Under the right circumstances, a quantum particle can do the same thing — it can “fall” from a high energy state into a low energy state, even when it has to “fall” over the top of a barrier that’s even higher. You can picture an imaginary tunnel going through a mountain to get to a lower place on the far side without having to pass over the top of the mountain.

Relevance: This is exactly what two low-energy hydrogen nuclei do when they fuse to make a helium nucleus of even lower energy. They are “falling” into a lower energy state, cheating because they don’t have the 4 million volt initial investment. Quantum tunneling must be the explanation for how cold fusion happens, and in this sense the problem is solved, but physicists thought they knew how to predict where quantum tunneling happens and what the odds are, and in the situation of hydrogen nuclei inside a palladium crystal, they were pretty sure that quantum tunneling was unlikely. Could they have been wrong? This brings us to the third weirdness.

THREE — Equations That Can’t Be Solved
This is a well-kept secret of quantum mechanics. Physicists don’t like to talk about it.

Schrodinger Equation

The Schrödinger equation.

Erwin Schrödinger wrote down this famous equation in 1925. He solved it for one electron in the hydrogen atom and it worked perfectly. It was quickly accepted as the fundamental equation of quantum mechanics.

That’s not the secret. The secret is that he couldn’t solve it for two electrons. For just two electrons, the equation became too complicated to solve. In modern times, we solve equations like this with supercomputers that give a very good approximate solution, so we know that Schrödinger’s equation works well for two electrons. For three electrons, however, the equation is too complicated, even for the biggest supercomputer we have. Solving the Schrödinger equation becomes exponentially more difficult with each new particle you add.

Relevance: That means that everything you’ve ever heard about quantum mechanics in many-particle systems (like atoms larger than helium or any molecules or solids or even gasses) — it’s all based on approximations and heuristics and semiempirical models. Physicists don’t really know for sure how quantum particles behave collectively. So we can be surprised when something like cold fusion comes along, but we can’t be very surprised because we never really solved the full Schrödinger equation in the first place.

Aftermath of the Pons-Fleischmann Announcement

The smartest man I ever knew was Julian Schwinger, who shared a Nobel Prize with Richard Feynman before he taught me quantum mechanics at Harvard. Long after I graduated, Schwinger had moved to California where he learned about the Pons and Fleischmann announcement. Schwinger had as deep a background in quantum theory as anyone alive. From all he knew, he thought about how cold fusion might work and wrote up his theory in 1981.

With all his laurels, Schwinger was accustomed to deference when he submitted papers to the best physics journals but, this time, the Physical Review refused to even consider his theory. Every journal in the country had a policy of refusing papers on cold fusion.

Schwinger was incensed and wrote an angry letter, resigning from the American Physical Society: “The replacement of impartial reviewing by censorship will be the death of science,” he declared. Here is what he wrote about the experience.

To understand why even the towering figure of Julian Schwinger couldn’t get a cold fusion paper published, we have to go back to 1989. Immediately after the surprise announcement by Pons and Fleischmann in March, the physics community went a little crazy. A plan was hatched to use the prestige of MIT’s scientists to discredit the work. Before they could do any validation experiments, before they could gather a representative response from the scientific community, a statement was prepared and a press conference made headlines.

Pons and Fleischmann were accused not of incompetence but of headline-seeking fraud. “Everything I’ve been able to track down has been bogus, and I think we owe it to the community of scientists to begin to smoke these guys out,” said Ronald R. Parker, director of the Massachusetts Institute of Technology’s Plasma Fusion Center.

Director of the Plasma Fusion Center. Whoa! Can you smell a hint of conflict of interest? Not only was Parker steeped in a paradigm that made cold fusion impossible, his position and his salary were at stake. At the time, MIT was one of the world’s largest recipients of grants to develop hot fusion — a pie totaling hundreds of millions of dollars annually. If fusion turned out to be possible with a simple electrochemical cell costing a few hundred dollars, that funding would evaporate.

Over the ensuing months, a dozen laboratories around the world raced to replicate the results of Pons and Fleischmann. Meanwhile, dollar signs were flashing in the administrative eyes of the University of Utah, which claimed patent rights because the research was conducted on its campus by its employees. The university did not want Fleischmann to reveal exact details of their procedure until a patent could be granted. In addition, some of the ambitious scientists who tried to replicate cold fusion thought they might leapfrog ahead of Pons and Fleischmann with clever variations.

Before researchers could put their heads together and compare notes, the hot-minded fusion scientists at MIT prepared a preemptive strike. In an authoritative report to the Department of Energy, submitted in November 1989, they selectively cited all those labs that had failed to replicate the Pons-Fleischmann effect and left out those that reported success, including the US Naval Research Laboratory.

They snookered the news services. I remember reading news accounts of that report at the time and saying a sad goodbye to cold fusion. Like the great majority of physicists, I knew enough to judge that cold fusion was improbable, so it was easy to believe it was just too good to be true.

This is the original 1989 research article by Fleischmann and Pons. Mike McKubre explains why many of the early attempts to replicate it failed — it takes a long time to load the palladium with enough hydrogen to make it work. Over the years, dozens of labs around the globe have seen bursts of energy in deuterium experiments, and the current challenge is finding ways to turn the reaction on and off reliably.

For readers who are technically inclined, Steven Krivit wrote a good review of the state of the art a decade ago, and a bibliography is available from New Energy Times. I personally witnessed cold fusion demos and inspected the data at Stanford Research Institute (Mike McKubre), MIT (Peter Hagelstein), and the University of Missouri (Graham Hubler). Focardi et al first reported success using nickel instead of palladium in 1998. Here is a 2004 update on what Fleischmann was able to accomplish. This is a 2009 assessment of the technology from the US Defense Intelligence Agency.

Eugene Mallove, MIT alumnus and editor of Infinite Energy magazine, wrote these words in 2003 before being murdered in 2004:

“In fact, the story of cold fusion’s reception at MIT is a story of egregious scientific fraud and the coverup of scientific fraud and other misconduct — not by Fleischmann and Pons, as is occasionally alleged, but by researchers who in 1989 aimed to dismiss cold fusion as quickly as possible and who have received hundreds of millions of DOE research dollars since then for their hot fusion research.”

Wade Frazier recounts bribes, threats, and arrests of others who have tried to commercialize breakout energy technologies.  I think it’s fair to say that various powers have brought their own interests and agendas to how we power our world, and much has transpired behind the scenes and the headlines in this field.

Next week: Powerful interests are hellbent on keeping cold fusion technology from the public. Are there other reasons, besides the economic conflicts?

    • Yes — in writing for a wider audience, I talk about “volts” because everyone has a pretty good feeling about what a volt is, but “electron volts” takes some explanation that leaves people behind unnecessarily.

  1. The problem with “true” science is that it has not read the scientific articles. There is much we do not know about the nature of things. Many times, “modern” science does not believe something can happen in nature until it does.

    I believe early believers in electronics believed that electrons could only pass through a diode in one direction, until it did; via tunneling thus the Zener diode.

    One major outcome of a nuclear warhead is the EMF that can zap electronics (especially memory devices). We found this only as an aftereffect of nuclear testing.

    In the quantum world, we may not necessarily see the same results as the world in general. For example, the half-life of a substance is meaningless when there are just a few atoms in the experiment.
