Rossi claims 600 degree e-cat working

Italian inventor Andrea Rossi, who claims to solve the world energy problems with the e-cat device based on Nickel-hydrogen LENR, recently reported significant progress on a working e-cat device operating at 600 degrees. Earlier it was reported the e-cat  device would become unstable at temperatures above 200 C.  If true, this would be very significant. 600 degrees C would take the e-Cat to levels where it could produce superheated steam as used in conventional electrical generation, earlier it was operating at much lower temperatures and discussed as heating device for the market launch in the US.  However not surprisingly, at this point in time there is no independent confirmation or  diligent third party examination of the claims.
