Abstract
The invention disclosed provides a new improved chemical method for combustible fuel production by converting carbon dioxide in the atmosphere to a carbonate following which the recovered carbonate is combined with hydrogen gas to produce combustible fuels e.g. methane and methanol. The present method provides means for fuel generation and may advantageously use heat and radiation energy derived from nuclear reactors. This application implies certain environmental advantages, in that burning of fuels containing carbon derived only from atmospheric CO.sub.2 would not add to the CO.sub.2 content of the atmosphere. Recycling of lime as CaO or Ca(OH).sub.2 would eliminate the problem of disposing of those materials as encountered by others teaching use of carbonates but not using such a closed cycle.
