The the chairman of an aerospace company says the plan put an artificial moon up over the city of Chengdu could potentially saving millions in electricity costs. The plan, possibly ready by 2020, would put the moon in orbit about 310 miles above the city. It would serve as a giant night light, reflecting sunlight down onto the city and replacing some streetlights. It reportedly could be targeted to light up specific areas, several times brighter than the real moon.
The rub? A huge amount of critics and a higher orbit is needed for the “moon” to be stationary and not orbit earth. But, critics also say it could very well work.
