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

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.

It can be done. It takes energy. The same energy we got by burning the fossil fuels in the first place, plus more to account for inefficiencies. A lot more, since internal combustion engines are very inefficient.

If we had a sufficient energy source we could reduce CO2, but then we wouldn’t need hydrocarbon fuels in the first place.

It’s much more efficient to use new, green energy sources as a replacement for fossil fuel, than burn dirty carbon and try to re-capture the CO2 out of the air.
