Brainchild of libertarians, seasteads are brand new cities built upon the ocean. It's not as far-fetched as it sounds, according to this article's author, but it will have to overcome the myriad engineering, energy, and legal challenges.
"Even once a viable blueprint for the structure of a seastead is produced, the technical challenges are not over. The more it relies on land-based supplies of fuel and water, the harder it will be to achieve the libertarian dream of escaping the evil ways of existing governments. At sea there is plenty of wind and wave energy, and occasionally sunshine, but building renewable-energy systems that can survive harsh ocean conditions is even harder and more costly than designing land-based ones."
