5 Reasons Cold Fusion is Bunk

Fusion, the same process that powers stars including the sun, would be a relatively clean, safe and near-limitless source of power. Unlike the fission of nuclear reactors that splits atoms to make energy, fusion fuses atoms. In nature, a star's immense gravity works to do the job of crushing hydrogen nuclei, protons, to create the reaction. But on Earth, crushing hydrogen atoms is no easy matter. It typically requires a machine that generates plasma -- atoms stripped of their electrons -- and runs at ultra-high temperatures in the millions of degrees Fahrenheit range. In short, more energy gets put in than what comes out, and that is not efficient.

But some scientists are trying to figure out how to get a fusion reaction to occur at room temperature. If successful, a so-called "cold fusion" machine would require little energy to run, but conversely produce a tremendous amount. In 1989, two scientists, Stanley Pons and Martin Fleischman, said they managed to achieve cold fusion, but after some initial excitement, the general consensus was that they didn't achieve cold fusion and in fact probably never would.

In the last couple of years, Italian inventor and entrepreneur, Andrea Rossi, claims he has achieved cold fusion with his "Energy Catalyzer," or "E-Cat" machine. The latest news is a supposedly independent test that validates his claims of a machine that somehow emits more energy (as heat) than it gets from the electrical outlets it is plugged into. A paper describing the test was posted on the ArXiv, a site where scientists post research before it goes for full peer-review.
