In recent days, we've sent you information concerning two United States Patents: "Patent US2605174 - Synthesis Gas Manufacture; July, 1952; Assignee: Phillips Petroleum Company" and "2,347,682 -
Hydrocarbon synthesis; May, 1944; Assignee: Standard Oil Company of Indiana".
Both of those documents detail and confirm that the petroleum industry and, at least as it is embodied in the Patent Office, our own United States Government knew, more than half a century ago, that Carbon Dioxide, as is emitted, relative to natural sources, such as volcanism, in a very small way by our varied and productive uses of Coal, is a valuable raw material resource.
