The thing that prevents this from materialising is that it requires energy. For the most part, we get energy from.. converting solid carbon to CO2. Unfortunately, due to 2nd law of thermodynamics, this conversion always incurs a loss of energy in the form of heat.
We can also get energy from other sources, such as solar radiation, but I think you get the gist - the most cost-effective way to carbon capture is not to release the carbon in the first place.
