Patent ID: 8516794

Claim:
A method of aspirating a fuel combustion engine with non-atmospheric gases to produce a subsequently useful byproduct, the steps of the method comprising: sequestering CO 2 gas from an subterranean cavity; combining the sequestered CO 2 gas with a predetermined amount of oxygen gas comprising at least 90% O 2 by weight to create an precombustion gas stream comprising the sequestered CO 2 gas and the oxygen gas; aspirating a fuel combustion engine exclusively with the precombustion gas stream, wherein the fuel combustion engine internally combusts the precombustion gas stream with a hydrocarbon fuel; collecting exhaust gas from the fuel combustion engine, wherein the collected exhaust gas comprises CO 2 created during fuel combustion, and wherein the collected exhaust gas comprises greater quantities of CO 2 than existed in the precombustion gas stream; and removing O 2 from the collected exhaust gas such that the collected exhaust gas comprises less than 5% O 2 by weight.
