Greenhouse gas CO2 is increasing at alarming rate, making our earth hotter everyday. The temperature in the western has crossed all records, reaching above 400 C. There is a threat to melting of north pole ice which may create to wakeup of dormant virus whose vaccine ,today, is not available . Thus it is a high time to consume and convert the excess CO2 in the environment to any form of non polluting useful product. The present works investigates electrochemical conversion of CO2 in the polluting smoke to ethanol in a fuel, controlled by Robotic automation. The level of CO2 and other harmful gases are monitored by robot controlled gas sensors. Electrodeposited Nickel acts as electrocatalytic cathode for CO2 conversation and Carbon anode at anode chamber oonized H2 to 2H+ which reacts with cathodic organic product generated from CO2 to form ethanol. The presence of ethanol is detected by UV-Vis spectrophotometer. In addition the electrochemical reaction in the fuel cell produces pure electrochemical energy in the form of current and potential with no polluting products. The steady state current delivered is around 20mA per cm2 of the electrode surface area. This is more than enough to drive a motor, if a battery of 10 cells ( each having 100cm2 electrode area ) is fabricated.
