Waste heat which would otherwise be lost up a stack or chimney may be employed to generate hydrogen or hydrogen peroxide through the use of special equipment including a heat exchange structure associated with the stack or chimney. Through one heat exchange structure, water is formed into steam. Then, in one or more additional heat exchangers, the steam is converted into hydrogen gas and/or hydrogen peroxide. The active material in the additional heat exchanger arrangements may include both (1) a metal oxide, such as manganese oxide, which successively sequesters oxygen from water vapor, and then as the pressure is reduced in later portion of the cycle, releases the captured oxygen; and may also or alternatively include (2) host and sensitizer material for shifting the output radiation into one of the absorption bands for water vapor. Additionally, through the very high intensity infrared radiation which is applied in a concentrated manner to the steam, further dissociation of the water vapor by the phenomenon of multiphoton absorption, is obtained; and suitable resonant cavity and high pass filtering film arrangements may be employed to shift the frequency of radiation applied to dissociate the water vapor into the ultraviolet frequency range.
