The invention relates to a method and apparatus for controlling the dissociation
of water into hydrogen and oxygen, the method including contacting a quantity of
aqueous liquid with a quantity of dissociation initiating material in a reaction
vessel; monitoring the temperature and/or pressure in the reaction vessel; monitoring
the surface area of dissociation initiating material in contact with the aqueous
liquid; and controlling the surface area of dissociation initiating material in
contact with the aqueous liquid in response to the temperature, pressure, or both,
or changes therein, or both, in the reaction vessel.
