Rossi adds externally generated heat to reach and maintain steady state heat production equilibrium.
One passive way to decrease reactor heat production is to decrease hydrogen pressure. This can be done by absorbing hydrogen from the hydrogen envelope using a hydride producing metal; for example, titanium. Provide an amount of titanium powder in a dedicated chamber separated from the main reaction chamber by a thermally regulated pressure valve. As the heat increases, hydrogen is removed from the reaction chamber using the passive pressure relief valve. A titanium hydride will be produced and hydrogen will be stored. To get the reaction going again, heat the titanium hydride powder to liberate hydrogen. This will get the pressure of the hydrogen envelope back up to self-sustaining levels. As long as the passive pressure relief valve is working, a melt down and resulting hydrogen explosion will not occur.
