Long considered science fiction, floating cities may begin to take shape as soon as 2020. According to the Seasteading Institute, a nonprofit aimed towards building startup societies, the world's first floating nation will test new ways on feeding the hungry, curing the sick, and cleaning the atmosphere.
These islands will be their own countries, float in international waters, and operate within their own laws. Twenty thousand dollars have already been raised for the project, and construction is expected to begin in 2019.
