Re: Eight times brighter than the Moon?

"and there's no way this could come anywhere near the amount of light you get from a full Moon."

Of course it can, and the article states that it will be 8 times brighter. The Moon is not only much further away, but most of the light it reflects does not hit the Earth. The mirror would focus 100% of the light it reflects onto a tiny fraction of the Earth's surface. (In fact the Moon, being convex, is exactly the *wrong* shape for an efficient light-mirror).
