Cold fusion returns to the debate over itself. Rossi and Focardi say that, when the atomic nuclei of nickel and hydrogen are fused in their reactor, the reaction produces copper and a large amount of energy. The reactor uses less than 1 gram of hydrogen and starts with about 1,000 W of electricity, which is reduced to 400 W after a few minutes. Every minute, the reaction can convert 292 grams of 20°C water into dry steam at about 101°C. Since raising the temperature of water by 80°C and converting it to steam requires about 12,400 W of power, the experiment provides a power gain of 12,400/400 = 31. As for costs, the scientists estimate that electricity can be generated at a cost of less than 1 cent/kWh, which is significantly less than coal or natural gas plants. [more inside]

New study claims cold fusion is possible
'A paper by a team of researchers at Tennessee's Oak Ridge National Laboratory who say they have discovered evidence of what looks like nuclear fusion taking place in a relatively inexpensive tabletop device.' You have to go back to 1989 for the last claim
of this kind. Cheap energy - the answer to America's dreams, or Bush's biggest nightmare? (Via Techdirt
