Cold fusion, briefly hailed as the silver-bullet solution to the world's energy problems and since discarded to the same bin of quackery as paranormal phenomena and perpetual motion machines, will soon get a new hearing from Washington.
Despite being pushed to the fringes of physics, cold fusion has continued to be worked on by a small group of scientists, and they say their figures unambiguously verify the original report, that energy can be generated simply by running an electrical current through a jar of water.
Last fall, cold fusion scientists asked the Energy Department to take a second look at the process, and last week, the department agreed.
No public announcement was made. A British magazine, New Scientist, first reported the news this week, and Dr. James F. Decker, deputy director of the science office in the Energy Department, confirmed it in an e-mail interview.
"It was my personal judgment that their request for a review was reasonable," Dr. Decker said.
For advocates of cold fusion, the new review brings them to the cusp of vindication after years of dismissive ridicule.
"I am absolutely delighted that the D.O.E. is finally going to do the right thing," Dr. Eugene F. Mallove, editor of Infinite Energy magazine, said. "There can be no other conclusion than a major new window has opened on physics."
The research is too preliminary to determine whether cold fusion, even if real, will live up to its initial billing as a cheap, bountiful source of energy, said Dr. Peter Hagelstein, a professor of electrical engineering and computer science at the Massachusetts Institute of Technology who has been working on a theory to explain how the process works. Experiments have generated small amounts of energy, from a fraction of a watt to a few watts.
Still, Dr. Hagelstein added, "I definitely think it has potential for commercial energy production."
Dr. Decker said the scientists, not yet chosen, would probably spend a few days listening to presentations and then offer their thoughts individually. The review panel will not conduct experiments, he said.
"What's on the table is a fairly straightforward question, is there science here or not?" Dr. Hagelstein said. "Most fundamental to this is to get the taint associated with the field hopefully removed."
Fusion, the process that powers the Sun, combines hydrogen atoms, releasing energy as a byproduct. In March 1989, Drs. B. Stanley Pons and Martin Fleischmann, two chemists at the University of Utah, said they had generated fusion in a tabletop experiment using a jar of heavy water, where the water molecules contain a heavier version of hydrogen, deuterium, and two palladium electrodes. A current running through the electrodes pulled deuterium atoms into the electrodes, which somehow generated heat, the scientists said. Dr. Fleischmann speculated that the heat was coming from fusion of the deuterium atoms.
Other scientists trying to reproduce the seemingly simple experiment found the effects fickle and inconsistent. Because cold fusion, if real, cannot be explained by current theories, the inconsistent results convinced most scientists that it had not occurred. The signs of extra heat, critics said, were experimental mistakes or generated by the current or, perhaps, chemical reactions in the water, but not fusion.
Critics also pointed out that to produce the amount of heat reported, conventional fusion reactions would throw out lethal amounts of radiation, and they argued that the continued health of Drs. Pons and Fleischmann, as well as other experimenters, was proof that no fusion occurred.
Some cold fusion scientists now say they can produce as much as two to three times more energy than in the electric current. The results are also more reproducible, they say. They add that they have definitely seen fusion byproducts, particularly helium in quantities proportional to the heat generated.
After a conference in August, Dr. Hagelstein wrote to Energy Secretary Spencer Abraham, asking for a meeting. Dr. Hagelstein; Dr. Michael McKubre of SRI International in Menlo Park, Calif.; and Dr. David J. Nagel of George Washington University met Dr. Decker on Nov. 6.
"They presented some data and asked for a review of the scientific research that has been conducted," Dr. Decker said. "The scientists who came to see me are from excellent scientific institutions and have excellent credentials."
Scientists working on conventional fusion said cold fusion research had fallen off their radar screens.
"I'm surprised," Dr. Stewart C. Prager, a professor of physics at the University of Wisconsin, said. "I thought most of the cold fusion effort had phased out. I'm just not aware of any physics results that motivated this."
How 'about realignment of carbon atoms from graphite into diamond...by squeezing lumps of coal between my butt cheeks?
I'm serious- if nothing is impossible, would you support my efforts (with money..or at least with written support on FR) to "figure out" how to make that happen?
Iconoclasm often a healthy, useful attitude. But we have a finite amount of resources, and non-trivially larger number of claims. Gotta do something to sort between them.
Diesel cars typically get more miles per gallon than comparable gasoline cars. I think VW has a diesel Jetta that gets around 50mpg. Diesel engines also last longer than gasoline engines.
The hybrid gas-electric compact cars are an expensive novelty that don't get a lot of improvement over comparable traditional cars and won't make a difference in the overall gasoline consumption of this country.
Hear hear! I would add that so-called "city planners" need to not wait 2+ years to expand a two-lane road into the 4-6 lane road needed for the development they've allowed. Here north of Dallas I've seen huge traffic jams that could have been solved by anticipating growth and planning for it. It seems the folks who issue the permits for mega-apartment complexes in the sticks don't talk to the roads people all that much. And don't get me started on mis-timed traffic lights..!
I have developed a new energy-generating process that involves burning the New York Times. It works with the LA Times and Newsweek too. I will be publishing details shortly.
Amen to that, Oberon! You've got to look at the whole picture, cradle to grave.
Same point should be made with hydrogen-powered cars. Water would be the most likely source of hydrogen for these cars, but how much energy does it take to first get the hydrogen, then store and transfer it. Same goes for hybrids and electrical transmission. At the consumer level, they might seem like great ideas, but in the big scheme are they any more efficient?!?!
There's a life cycle analysis I remember seeing some time ago. Ask anybody whether oil-based paint or water-based paint is better for the environment, and you're likely to hear, hands-down that water-based paint is better. However, if you look at the life cycle and what really goes into the products, it's not as clear: water-based paints are produced using vinyl and acrylic polymers...which are derived from non-renewable petroleum; oil-based paints are primarily produced (at the consumer-level, anyway) using renewable vegetable (soybean, linseed, sunflower, tung) oil based resins, in some cases actually thinned with the raw oils instead of petroleum-derived solvents.
When you look at the big picture, the answer isn't as obvious as you might have thought!
What, you say?!?! Even with a 50,000 gallon tank of deuterium saddled up in the back of my Suburban and a heat exchanger capable of operating at a dtlm of 0.01 F, I'm still gonna need an extension cord to get to the Piggly Wiggly?
...I'm sure they said that about "Flying Machines" (as in heavier-than-air flights), Too? :)
