Re: Is this too good to be true?
It will take energy to extract CO2 from the atmosphere. That energy has to be produced somehow, likely generating more atmospheric CO2 in the process. However, it may take less energy to simply extract the cO2 than to go further and convert it back into a fuel. In that case we aren't recovering our fuel supplies, and they will be depeleted eventually. Either way the carbon dioxide will once again be extracted by the vast expanses of plant growth around the world.
