Hi Fran: Yes, agreed... The comment about steam was only half serious! The thought there was that the steam was 'exhaust' and dilution of the 'fuel' with exhaust would decrease efficiency. But that was thinking of this thing like an internal combustion engine...
However, no one has commented at all about the main point of my posting. There was all this concern and angst about a runaway reaction and, oh my, how dangerous this is, and its going to be soooooo difficult to make a 'safe' reactor. It has been said, by Rossi himself, that the reaction stops very quickly (within seconds, or a few tens of seconds?) after you stop the hydrogen flow... -Mark -----Original Message----- From: Roarty, Francis X [mailto:[email protected]] Sent: Wednesday, January 19, 2011 5:08 AM To: [email protected] Subject: RE: EXTERNAL: [Vo]: how to stop runaway condition...

[/snip] Hi Mark, I agree a reaction quashing gas is a good idea but not steam which is very reactive and could permanently damage the catalyst- rather an inert gas like helium to quickly change pressure and ratio of available reactants to activated geometry. You might have to purge the gas mix before restarting but at least the catalyst should still be activated. Regards Fran
