Engineering360: "Solar Conversion of CO2 to CO with Low-cost Catalyst"

Why would you want to change CO2 to CO???

CO is poisonous, while CO2 is plant food the earth needs more of, it is environmentally harmless and it is not a pollutant. Man-made CO2 stays on the ground where it is produced as it is 1.5 times heavier than air. CO turns back into CO2 naturally anyway.

If your answer is: 'Because of Global Warming' you would be dead wrong. Firstly, man has no influence whatsoever about it, and secondly, Global Warming is good.

I wish it would get warmer, temperatures have not changed in the last 15 to 20 years.

It is time to get off the 'politically correct' band wagon.

"Scientific" charades aside, CO is used in many industrial settings (e.g. metallurgy, to make synthetic diesel, lasers, etc)-- it would not be released into the atmosphere, my friend.
