An article by Michael Brooks about Cold Fusion gives a brief history of the phenomena and some of the current research from “a small band of believers” that supports it . A scientist is quoted as saying there’s no theory to support Cold Fusion and we often hear that none of the data from these experiments matter until there’s a theory to explain them. This reminds me of the France’s Academy of Sciences view in the eighteenth century that meteorites didn’t exist because there was no theory to explain them: the Academy confiscated almost all of them from French museums in the 1700’s except one really big meteorite. You’ll find very few old ones in French museums today. Here’s a brief summary of Brook’s article at E-Catworld.
