Floating seascrapers of the future?

Touted as an eco-friendly floating city, the Seascraper (pictured in an artist’s conception) is among a raft of concepts for  sustainable offshore settlements. With more than seven billion people on  the planet, mass migrations to cities, and increased risks of flooding  and sea level rise, more and more architects and innovators seem to be  weighing anchor.

The  Seascraper—a self-sufficient community of homes, offices, and  recreational space—was designed with the intention of slowing urban  sprawl, according to its designers.

The  vessel’s energy independence would come from underwater turbines  powered by deep-sea currents as well as from a photovoltaic skin that could  collect solar energy. The concave hull would collect rainwater and  allow daylight to reach lower levels. Fresh water would come from  treated and recycled rainwater via an onboard desalination plant.

This  green machine would also help keep marine populations afloat, so to  speak, with a buoyant base that serves as a reef and discharges fish  food in the form of nutrients pumped from the deep sea, the U.S. design  team says.
