(76) As shown in FIG. 13, a method for CO2 absorption to conversion for end-consumer consumable is generally designated 1400. At block 1401, CO2 is absorbed or adsorbed at a tailpipe apparatus of a tailpipe of a vehicle via a sorbent. At block 1402, the CO2 is stripped from the sorbent utilizing a chemical process. At block 1403, the stripped CO2 is converted to an end-consumer consumable. In one example, a sorbent is placed within an initial compartment of a CO2 conversion device not attached to the light duty vehicle.

There is preferably a dispensable component that can dispense the CO2 free sorbent from the device back into the tailpipe apparatus. There is preferably a side water cartridge compartment in the device to add water to possibly aid in the CO2 stripping process. As the CO2 is released from the sorbent, excess molecules such as water either flow back to the water cartridge compartment or flow to a membrane compartment. The isolated CO2 gas travels to an electrochemical membrane which can convert the CO2 into ethanol. The reaction will preferably create ethanol and CO2, which will preferably be filtered so the CO2 will continuously cycle through the membrane until converted into ethanol. The ethanol preferably drips into a multi-gallon removable compartment that is preferably used to refuel vehicles.
