Lighting the dark (night) areas on earth with sun light conveyed from bright areas?

The sun never stops shining to our earth. But while one half of the earth is abundantly shined with bright sun light, the other half is in dark and electrical lights must be used. Imagine that we could convey the sun light from the bright (day) areas of the earth to the dark (night) areas, huge energy will be saved, together with many other benefits when our night is shined with natural sun light!

Optical fiber cable can be thought for that conveyance. Sun lights from the brighting areas are captured, concentrated, fed into the optical fibers (ideally the optical fibers form a global ring circling around the earth’s equator) and conveyed to the night areas on earth. One night area (the light "receiver"), when on its turn becoming a bright area at day, will vice versa play as the source of sun light (the light "transmitter") for the other night areas on earth.

Of course how the optical fiber cable can convey the light over long distance is the biggest (technical) challenge, secondly whether all the nations on our earth are willing to cooperate for the global utilizing and sharing of the most valuable and important resource that the Nature generously grant us?

How would you think about such global light sharing idea?

Thank you.
