Breakthrough process has potential to provide inexhaustible source of energy

SALT LAKE CITY - Two scientists have successfully created a sustained nuclear fusion reaction at room temperature in a chemistry laboratory at the University of Utah. The breakthrough means the world may someday rely on fusion for a clean virtually inexhaustible source of energy.

Collaborators in the discovery are Dr. Martin Fleischmann, professor of electrochemistry at the University of Southampton, England, and Dr. B. Stan­ley Pons, professor of chemistry and chairman of the Department of Chemistry at the University of Utah.

"What we have done is to open the door of a new research area," says Fleischmann. "Our indications are that the discovery will be relatively easy to make into a usable technology for generating heat and power, but continued work is needed, first, to further understand the science and secondly, to deter­mine its value to energy economics."

Nuclear fusion offers the promise of providing humanity with a nearly un­limited supply of energy. It is more desirable than the nuclear fission process used today in nuclear power plants. Fusion creates a minimum of radioactive waste, gives off much more energy and has a virtually unlimited fuel source in the earth's oceans.

Nuclear fusion is also superior to traditional energy sources, such as coal, gas and oil, which can pollute the environment and eventually will be depleted. Using fusion for energy would reduce or even eliminate major causes of acid rain, the greenhouse effect and U.S. dependence on foreign oil.

Their findings will appear in the scientific literature in May.

Scientists worldwide have searched for more than three decades for the ability to create and sustain nuclear fusion reactions, which are thought to be the ideal energy source. In nature, the energy of stars, such as the sun, is supplied by nuclear fusion. All fossil fuels presently used on earth are simply storehouses of stellar nuclear fusion energy. Prior to the breakthrough research at the University of Utah, imitating nature's fusion reactions in a laboratory has been extremely difficult and expensive.

In the Utah research, the electrochemists have created a surprisingly simple experiment that is equivalent to one in a freshman-level, college chemistry course. Conventional nuclear fusion research requires temperatures of millions of degrees, like those found in the sun's interior, to create a reaction. The Utah research, however, creates the reaction at room temperature.

In the experiment, electrochemical techniques are used to fuse some of the components of heavy water, which contains deuterium and occurs naturally in sea water.

Sea water provides essentially an unlimited source of deuterium. Even though it is present at only one part in 38,000, one cubic foot of sea water contains enough deuterium to produce 250,000 BTU of energy, which is equi­valent to the energy produced from 10 tons of coal.

The scientists know their experimental result is fusion in an electrode be­cause the generation of excess heat is proportional to the volume of the elec­trode. "This generation of heat continues over long periods, and is so large that it can only be attributed to a nuclear process," Fleischmann says. "Furthermore, side reactions lead to the generation of neutrons and tritium which are expected by-products of nuclear fusion." The device the researchers have con­structed produces an energy output higher than the energy input.

Pons calls the experiment extremely simple. "Observations of the phenome­non required patient and detailed examination of very small effects. Once characterized and understood, it was a simple matter to scale the effects up to the levels we have attained."

The researchers' expertise in electrochemistry, physics and chemistry led them to make the discovery. "Without our particular backgrounds, you wouldn't think of the combination of circumstances required to get this to work," says Pons.

Some may call the discovery serendipity, but Fleischmann says it was more accident built on foreknowledge. "We realize we are singularly fortunate in having the combination of knowledge that allowed us to accomplish a fusion reaction in this new way."

The idea to attempt the innovative experiment was seeded in the late 1960s when Fleischmann conducted research on the separation of hydrogen and deuterium isotopes. The results were odd. His interpretation of the data indi­cated it would be worth looking for nuclear fusion reactions.

Later, in separate research, Pons looked at isotopic separation in electrodes and was puzzled at certain results. The two pondered the data and later dis­cussed the findings on two memorable occasions, once when they drove together through Texas and later when they took a hike up Millcreek Canyon on the outskirts of Salt Lake City.

"Stan and I talk often of doing impossible experiments. We each have a good track record of getting them to work," says Fleischmann. "The stakes were so high with this one, we decided we had to try it.

"The research strategy was concocted in the Pons' family kitchen. The nature of the experiment was so simple, says Pons, that at first it was done for the fun of it and to satisfy scientific curiosity. "It had a one in a billion chance of working although it made perfectly good sense."

The two performed the experiment and had immediate indication that it worked. They decided to self-fund the early research rather than try to raise funds outside the University because, says Pons, "We thought we wouldn't be able to raise any money since the experiment was so farfetched."

Working late into the night and on weekends at Pons' University of Utah laboratory, the two improved and tested the procedure throughout a five-and-­half year period.

"We hope we'll be able to work with others to develop this into a useable technology for generating heat and power for the world," says Fleischmann. "The process is clean and indications are it will be economical compared to conventional nuclear systems." (Source: New Energy Times)

Fleischmann has written more than 240 articles in the electrochemical, physics, chemistry and electrochemical engineering fields during his 40-year career, and is regarded as one of the leading electrochemists in the world. He is a fellow of the Royal Society of England. He was awarded a medal for Electro­chemistry and Thermodynamics by the Royal Society of Chemistry in 1979; the Olin-Palladium Medal of the Electrochemical Society in 1985; and the Bruno Breyer award by the Royal Australian Chemical Society in 1988. He earned a doctorate in chemistry at London University in 1951.

He and Pons have collaborated on 32 articles.

Pons has authored more than 140 articles and lectured throughout the United States, Canada and Europe. He earned a bachelor of science degree at Wake Forest University, Winston-Salem, North Carolina in 1965 and a doc­torate at the University of Southampton, England, in 1979. He is originally from Valdese, North Carolina.

Working on the project with the two scientists is University of Utah grad­uate student Marvin Hawkins from LaJara, Colorado.

The fusion technology is owned by the University of Utah which has filed patent applications covering the technology. Information about commercial aspects of the technology development can be obtained from Dr. Norman Brown, director of the University of Utah Office of Technology Transfer. 801-­581-7792.

The researchers are grateful for the encouragement of the United States Office of Naval Research, their respective universities, families and colleagues.
