Patent ID: 8561390

Claim:
An energy production and pressurized exhaust gas storage system comprising: two combustion chambers aligned in opposition to each other, each of the two combustion chambers comprising a first wall having a first diameter; a power piston within each of the two combustion chambers, each power piston slidably engaging the first wall of one of the two combustion chambers and able to reciprocate therein; a compression chamber situated between the two combustion chambers, the compression chamber comprising a second wall having a second diameter; a compression piston within the compression chamber, the compression piston slidably engaging the second wall of one of the compression chambers and able to reciprocate therein; a shaft connecting each power piston and the compression piston so that the compression piston and both power pistons reciprocate as a unit; a solvent tank flowably connected to the two combustion chambers such that carbon dioxide from combustion is exhausted to the solvent tank, the solvent tank comprising a solvent capable of dissolving the carbon dioxide; a pressurized carbon dioxide storage chamber flowably connected to the compression chamber; and a plurality of check valves enabling inflow of carbon dioxide to the compression chamber from the solvent tank and outflow of carbon dioxide pressurized in the compression chamber to the pressurized carbon dioxide storage chamber.
