Both Rossi and ME356 tell us that they can turn the LENR reaction off and on in there respective reactors like a switch can instantaneously turn the lights off and on. ME356 go further to say that the temperature pressure stays the same for both the on and off traction condition.
We all assume that a special form of hydride is responsible for the LENR reaction, but what most theories don't explain is how the reaction can be turned off and on with such a slight change in conditions. The chemical nature of the hydride does not have any time to change especially when the temperature and pressure remains the same. The reaction is sensitive to the nature of the EMF stimulant that is is exposed to. The special hydride is therefore dependent on a special EMF induced state that is activated when the reaction turns on. LENR theorists must explain what the stimulant is and how it produces the LENR reaction.
