Engineering:Artificial moon
From HandWiki
An artificial moon is a satellite put into a planet's orbit to reflect sunlight back to that planet.
By 2022, China plans to have three artificial moons in orbit around the Earth.[1] [2] These will shine 8 times brighter than the natural moon.[3] By having this as a light source, China believes it could save over a hundred million dollars a year from the cost of electricity used for streetlights.
Concerns
There are some concerns about how the absence of a normal day and night cycle will effect the minds and bodies of humans and animals.[4]
