See new article. There are some statements in this article I have not heard, and some stuff I doubt is true:
http://pesn.com/2011/07/21/9501874_Rossis_Self_Sustaining_One_Megawatt_Reactor/ I think it is more likely that it will require minimal input energy. The input to output ratio will be high. People here have described the ratio as 1:6. That it may be in many recent tests, but it has been much higher in some other tests, and it has been infinite in heat after death. There is no reason whatever to think it is stuck at 1:6. That is just a matter of engineering. I think someone here referred to the idea that the device is a sort of energy amplifier. That is, something that uses a flow of energy to tap into a source of energy and extract it at rate depending on input power. I do not think any cold fusion reactor fits this description. The connection between input energy and output heat is complicated and indirect. With the electrochemical cells, all else being equal, output is somewhat proportional to input because high input boosts high loading which in turn boosts the heat. But I would not call that amplification. - Jed
