Yes, this is a neat idea, a big idea, a visionary idea. What bothers me about it is the sheer temerity of placing a new, super bright star that, if I understand the situation correctly (and I might not), would be visible in everyone's sky, all over the world. It would give astronomers apoplexy, and would compromise the sanctity of the sky, which is still, I think, something that everybody values.
However, if it actually is the case that it could only be seen locally then I take it all back. Cities are bright anyway, obscuring almost all the stars.
How would something like this fare in the U.S.? There'd be fierce opposition from one party or another. Utility companies, maybe? (Although they seem intent on reducing electricity usage so they don't have to build new power plants.) Whatever, the autocratic government in China, for better or worse, makes grand projects possible that wouldn't be possible elsewhere.
