A Floating Airport?

The Infrastructurist writes, "The floating airport would be a city unto itself–a green city, even, as it would harvest energy from wind, waves and ocean currents. A massive on-board desalinization plant would also supply not only OceanWorks' needs, but pump clean water back to coastal cities, taking some pressure off existing sources like the Colorado River."

"Because the platform would be moored in water that's a thousand feet deep, there wouldn't be the same environmental concerns that crop up with projects closer to shore, where the ecology is more delicate."
