Waterscraper: the answer to crowded cities?

A room with a submarine view could provide an alternative to tight living quarters. One up on the yellow submarine – how about a giant floating underwater ‘skyscraper’ as your new abode? Your pad offers a 360º view onto shoals of herring and the occasional circling whale. Giant turbines harness power from the waves, the pedestrian port on the surface is sheltered by huge photovoltaic sunshades. And there’s no need to sail to the shore for your weekly shop: a combination of aquaculture, hydroponics and rainwater harvesting keeps the complex self-sufficient. – Anna Simpson This article is part of a series of Weak signals from the future.'Weak signals' are ideas, trends and technologies that are as yet unrecognised by mainstream society.
