Can it be real or is it fraud ?

Cold fusion was revealed to public in 1989 by Fleischmann and Pons, but results failed to repeat. Subsequently the mainstream research community denounced cold fusion as pathetic science, contradicting all known laws of physics. Journals refused to publish, patent offices rejected new patent applications. But some people continued with research. Andrea Rossi claimed to have build a machine….

If Italian inventor Andrea Rossi’s cold fusion machine, called the E-Cat, really works, then the world’s energy problems are all but solved. Rossi claims that a small amount of input energy drives a fusion reaction between hydrogen and nickel atoms inside his machine, producing an outpouring of surplus heat that can be used to generate electricity. And instead of the nasty radioactive byproducts given off by nuclear fission reactors — think Fukushima or Chernobyl — the E-Cat spits out just a teaspoon of copper.
