Patent ID: 7914758

Claim:
A CO 2 control system for capturing CO 2 , comprising: a gaseous flow having CO 2 therein, said gaseous flow resulting only from being an exhaust from an internal combustion engine or flue gas from a device that burns wood, oil, coal or gas; a flow-through apparatus through which said gaseous flow is directed; and a CO 2 absorbing filter unit having a fixed structure which is treated with one of an alkaline earth and an alkaline earth metal material and housed as a unitary element within the flow-through apparatus; wherein the CO 2 absorbing filter unit is replaceably mounted in said flow-through apparatus where the CO 2 absorbing filter unit is exposed to the gaseous flow; wherein said gaseous flow resulting from being an exhaust or flue gas freely passes through the CO 2 absorbing filter unit with minimal interruptions; wherein CO 2 from said gaseous flow is absorbed by the CO 2 absorbing filter unit as said gaseous flow freely passes thereby; and wherein the CO 2 absorbing filter unit is subsequently removed for recycling or sequestration of the absorbed CO 2 .
