Fifteen years after the University of Utah made the now infamous announcement that two of its chemists had produced "cold fusion" in their lab, the U.S. Department of Energy will review a new batch of claims by other researchers.

Even though most mainstream scientists consider cold fusion literally cold — as in dead cold — and at least one prominent critic thinks the DOE will be wasting its time, a band of researchers who have refused to give up are delighted by the review.

Although the DOE has received no proposals for new studies or provided new funding in the controversial field, research by what James F. Decker, deputy director of DOE Office of Science, calls some "excellent scientific institutions" the past 15 years deserves a look.

His interest was apparently sparked at least in part by a story in the Wall Street Journal on research results being reported at the 10th International Conference on Cold Fusion.

U. chemists B. Stanley Pons and Martin Fleischmann, announced March 23, 1989, that they had captured the process that powers the sun in a small apparatus working at room temperature.

The hope of limitless, cheap, electrical power faded quickly, even with a $5 million appropriation from the Legislature, as scientists around the world raced — with mixed outcomes — to duplicate the results. Eight months later, a special DOE review panel concluded that the research was almost surely an illusion.

Some scientists had announced they could not reproduce the results. A few believed they were achieving cold fusion. Others pointed to what they considered flaws in the Utah work. Critics became increasingly vocal, with some denouncing Pons and Fleischmann's findings as "pathological science." "A group of scientists requested a meeting with the Office of Science," Decker said in an e-mail. "I met with them sometime last fall. They told me about a lot of research on cold fusion that has been done since the last review that was conducted about 15 years ago. "They presented some data and asked for a review of the scientific research that has been conducted." These were from "excellent scientific institutions and have excellent credentials," Decker wrote. "It was my personal judgment that their request for a review was reasonable." The office will pass along the material they provided, to reviewers with the expertise to evaluate it. He expects the reviewers will spend a couple of days hearing presentations, then will individually offer their opinions on the science. Brigham Young University scientist Steven F. Jones, whose own research preceded the announcement by Pons and Fleischmann, said of the new DOE review, "I think it's high time, actually," adding that "there's a lot going on" in the field.
