The Prospect of Cold fusion

In March of 1989, Drs. Martin Fleischmann and Stanley Pons first announced that they had discovered a way of producing heat from metals supersaturated with heavy water. Thus at the University of Utah, cold fusion was discovered. In the weeks following this announcement many other scientists tried to replicate the same experiment, with little result. After many scientists and Universities came up empty handed, the possibility of cold fusion was called a fluke or a con mostly because none of the nuclear or chemical theoretical models could explain the observed cold fusion effects.

So it would not be surprising if you thought that cold fusion was “dead,” because the scientific establishment, the hot fusion community, and many in the news media have ignored the continuing cold fusion research. But cold fusion is far from dead. It is alive not only in dozens of laboratories in the United States, but in numerous foreign research centers, particularly in Japan.

Cold fusion is a real but still incompletely explained energy-producing phenomenon that occurs when ordinary hydrogen and the special form of hydrogen called deuterium are brought together with metals, such as palladium, titanium, and nickel. Usually, some triggering mechanism, such as electricity or even acoustic energy, is required to provoke the “cold fusion” effects. Both ordinary hydrogen and deuterium are abundant in ordinary water so the process would likely end many of the world’s energy concerns, if it can be developed commercially.

One of the biggest reasons that cold fusion is so difficult to replicate is that it is not easy to supersaturate a metal with hydrogen or deuterium. The electrolyte, hydrogen or deuterium gas must be kept free of impurities. The metal must be carefully manufactured, cleaned, prepared and pre-treated. As the metal lattice fills up, tremendous pressure is created, which causes most metal samples to fracture. This prevents high loading, which is a necessary condition for cold fusion

The most important evidence for cold fusion is the excess heat energy that comes from special electrochemical cells — much more heat excess power output beyond input power anywhere from 10% beyond input coming out than electrical energy being fed in. Researchers have now confirmed that under the proper conditions it is possible to obtain to many thousands of times the input power. In fact, in experiments reported at the Fourth International Conference on Cold fusion, one researcher, D. T. Mzuno of Hokkaido University, reported an output/input ratio of 70,000! Sometimes this power comes out in bursts, but it has also appeared continuously in some experiments for hundreds of hours, and in some cases even for many months.

And there is more. Neutrons, tritium, energetic charged particles, and other ionizing radiation have been detected in a variety of cold fusion experiments. In the past few years, there has also emerged startling experimental evidence that elements have been transformed in cold fusion experiments. Several laboratories have found helium-4, for example, and low levels of radioactive metal atoms. Isotopes of silver and rhodium have appeared from cold fusion cells where no such atoms existed before the experiments began.

Cold fusion cannot be classified as a chemical reaction or a nuclear reaction even though it does have some characteristics of each.

Cold fusion cannot be a chemical process because it consumes no chemical fuel and it produces no chemical ash. Cold fusion cells contain mostly water, which is inert material that cannot burn or undergo any other exothermic chemical reaction. Cells also contain metal hydrides, which can produce a small amounts of chemical heat, but cold fusion cells have produced hundreds of thousands of times more energy per unit of mass than any chemical cell could. For example, a cell containing 40 milligrams (0.04 grams) of metal hydride, and no other potential chemical fuel, produced 86 megajoules of energy over a two month period. The best conventional chemical fuel is gasoline; only a few exotic rocket fuels produce more energy per gram than gasoline, and they are not much better. It would take 2,000 grams of gasoline to produce 86 megajoules of energy, so the cold fusion cell was 50,000 times better. Furthermore, no cold fusion cell has ever shown any sign of petering out for lack of fuel. The cell that produced 86 megajoules was deliberately turned off after two months. If it has been left on it might have run for years, or decades. Nobody knows how long it might go.

Cold fusion does produce nuclear ash: helium, a low level of neutrons, and in some cases tritium and transmutations in the host metal. It produces trillions of times fewer neutrons than plasma fusion or fission, and most scientists believe that nothing resembling plasma fusion can take place in a metal lattice, so if cold fusion is a nuclear fusion or fission reaction, it must be very different than any known reaction. It is not yet clear whether the helium, tritium and other nuclear ash from cold fusion is sufficient to account for all of the heat generated. If it is not, then perhaps this is a new source of energy never observed before, which occasionally produces nuclear reactions as a side effect.

There are many differences between
