Who needs street lights? Chinese city plans fake moon

In Chengdu, there is reportedly an ambitious plan afoot for replacing the city's street lights: boosting the glow of the real moon with that of a more powerful fake one.

The capital of the southwestern Chinese province of Sichuan plans to launch an illumination satellite in 2020. According to an article in People's Daily, the artificial moon is "designed to complement the moon at night", though it would be eight times as bright. The "dusk-like glow" of the satellite would be able to light an area with a diameter of between 10 and 80km (six to 50 miles), while the precise illumination range could be controlled within tens of metres – enabling it to replace street lights.

The vision was shared by Wu Chunfeng, the chairman of the private space contractor Chengdu Aerospace Science and Technology Microelectronics System Research Institute Co (Casc), at a national mass innovation and entrepreneurship event held in Chengdu last week. Wu reportedly said testing had begun on the satellite years ago and the technology had now evolved enough to allow for launch in 2020. It is not clear whether the plan has the backing of the city of Chengdu or the Chinese government, though Casc is the main contractor for the Chinese space programme.

    a) This really depends on the density of the light pole field. But the variation is a killer, it takes like 30 minutes or so to perfectly accommodate for a healthy person! So you might be fairly blind all the time if the lights are badly placed.
    b) This is a good point but we could monitor not just movement but also speed and direction and illuminate accordingly. Does make things again a little more complex.
    c) KISS is always a great idea. And it's a shame we cannot see the wonderful night sky in cities. And already more than half of humanity lives in cities so they might never have seen the majestic star field above us.

    Yet another question is if you have street lights, why do they have to be so eye-piercingly bright. It's a street, not a hospital operations room..!

    I believe this Chinese grand scheme is in the same vein as the Transit Elevated Bus. [wikipedia.org]
