China plans to launch artificial moon to replace street lamps
"Space of the last frontier."
That, of course, is the opening line of the first "Star Trek" series. Nobody (outside China, as we will see soon) would see if the line was "Space, the next street light". However, that is exactly what the Chinese space program is saying. In 2020, it plans to launch a satellite with a reflective coating that it claims will be capable of emitting sunlight during the night in a 50-square-mile area that apparently has not yet heard of the street lights. Or Las Vegas. Or what animals and humans do when they can not sleep. What could go wrong?
"The light from the satellite will be like a twilight."
Kang Weimin, the director of the Optical Institute of the School of Aerospace Technology at the Harbin Institute of Technology, gave that very technical description after the announcement of Wu Chunfeng, president of Chengdu Aerospace Science and Technology, Microelectronics System Research Institute , Co, a city of 14 million people in southwestern China, will soon receive a second moon "eight times brighter than the Moon" (update your definition of "twilight" to "reflect" this). At a technology conference in Chengdu, he told the audience that the beam of this satellite will be bright enough to completely replace the street lights. "(Better update" twilight "again.) Why? Chengdu Business Daily gives an answer:
"According to reports, in the civil sector, the project can replace the nocturnal public lighting, saving a large amount of infrastructure in the consumption of electricity. In view of the 50 square kilometers of Chengdu, radiation, for example, can save electricity costs of about 1.2 billion yuan ($ 173 million) per year. "
Newspaper of the people Reports that Chengdu officials also expressed that artificial moon would increase tourism (see Las Vegas and New York City), while Times of Asia notes that light can be directed to specific locations, such as construction sites or disaster areas.
What could go wrong? Ask people who live in remote areas of the north or south with summers full of midnight suns. Or ask your psychologists who say that perpetual sunlight affects internal clocks, creates a perpetual jet lag feeling and contributes to insomnia and all of its associated serious problems (see Insomnia). The artificial moon will undoubtedly bother astronomers who will be able to see it when its light blocks its view and will affect the companies that depend on nighttime darkness. (Note to oneself: sell shares in the company of night-light).
Then there are the animals. Kang Weimin says that the "twilight" of all night will not affect them, but that is not the case in the midnight sun areas, which report that animals are hunting longer, birds sing and sing at all times, bears are in a bad mood and do not hibernate and those important bats that eat insects during the night eat less frequently. And those are just the obvious signs.
What could go wrong? Much. Enough to offset the profits of a billionaire space entrepreneur, his wealthy business friends and money-hungry government officials? What you think?
"The space ... the center of final benefit".
