It's 2020, carbon emissions are in decline but not fast enough. Oceans continue to rise at an increasing rate, so a plan is proposed to cut ALL carbon emissions:
Cover the moon in solar panels (take the center of the moon to be the origin, then the solar panels follow the planes: x=0, y=0, z = 0, where they intersect with the surface of the moon), so that at any given point in time (outside of lunar eclipse) they produce electricity. However there is a problem, how can the electricity be transferred from The Moon, to Earth, where it is needed?
Assume the electricity can be stored for a limited amount of time on both The Moon and Earth, so continuous electricity transfer is preferrable, Ideally efficiency of transfer over 50%, and to be economical for the long term.
