I think we can do this when we no longer have the sun.
In the mean time, while the sun is still greatly available (even at a certain time of the year for certain places), it is free and it is a great resource and useful for another present that has given to us from the very beginning - Trees.
If we can tackle corruption especially that causes deforestation and work with what we already have, nature, we could save half the cost of building machines that requires elements to dig up and destroy the earth more through mining for those minerals.
If China can do this, I know the rest of the world can too.

I think, we should just get one ready just in case. What my point is that we can do this to artificially reduce the ozone layer reduction and increasing the creation of oxygen for storage, where we might have a lot of need for that.
