is is possible to make captured carbon back into a useful solid form?

Question

For many years now I have wondered why we aren’t able to turn the air captured carbon into useful things like carbon fiber or carbon nanotube batteries. surely there must be some way of doing this through the magic of chemistry.

Answer 1

we can do it, it is the reverse of what happened when we burned the carbon in an engine. doing so costs energy (releasing that energy is why we burned it in the first place) and there are much easier ways to get raw materials.
