Royal Haskoning is planning a revolutionary airport in the the North Sea, just 20km off the coast of Holland, that features floating and rotating runways.
Passengers would be taken to the mainland by shuttles under the ocean via a maglev train. The 250 square kilometers of new land could take 25 years to create. They have planned for the rise in ocean levels due to global warming, however, and will install sand dunes instead of dikes.
