Techniques to synthesize greenhouse gases

A process for capturing carbon dioxide (CO2) emissions from a CO2 emitting passenger vehicle and converting the CO2 into an alcohol fuel, the process comprising:

• capturing CO2 emissions from an exhaust mechanism of the passenger vehicle at a CO2 capture device on the passenger vehicle;
• transferring the CO2 emissions to an electrolyzer;
• mixing the CO2 emissions with an electrolyte to create a CO2 aqueous mixture;
• transferring the CO2 aqueous mixture to an electrochemical cell, wherein the electrochemical cell comprises a proton exchange membrane, a gas diffusion anode and catalyst attached a first end to a first end of the proton exchange membrane, a first current collector and flow plate attached to a second end of the gas diffusion anode and catalyst, a gas diffusion cathode and catalyst attached on a first end to a second end of the proton exchange membrane, and a second current collector and flow plate attached to a second end of the gas diffusion cathode and catalyst;
• applying a voltage to the CO2 aqueous mixture within the electrochemical cell to generate an alcohol and byproducts;
• separating the alcohol and byproducts to separate the alcohol from the byproducts;
• and
• collecting the alcohol for use as a fuel for the passenger vehicle.

A process for capturing carbon dioxide (CO2) emissions from a CO2 emitting excavator and converting the CO2 into an alcohol fuel, the process comprising:

• capturing CO2 emissions from an exhaust mechanism of the excavator at a CO2 capture device on the excavator;
• transferring the CO2 emissions to an electrolyzer;
• mixing the CO2 emissions with an electrolyte to create a CO2 aqueous mixture;
• transferring the CO2 aqueous mixture to an electrochemical cell, wherein the electrochemical cell comprises a proton exchange membrane, a gas diffusion anode and catalyst attached a first end to a first end of the proton exchange membrane, a first current collector and flow plate attached to a second end of the gas diffusion anode and catalyst, a gas diffusion cathode and catalyst attached on a first end to a second end of the proton exchange membrane, and a second current collector and flow plate attached to a second end of the gas diffusion cathode and catalyst;
