Crazy Spike Covered Algae Powered Skyscraper Filters Polluted City Air
The ‘City Respiration Skyscraper’ might look malicious with its spiky exterior, but its intentions are 100% benevolent. Designed by Czech architects Pavlína Doležalová and Jan Smékal, the spiraling tower is a 240 meter-high structure covered by air-cleaning algae. The designers envision that a network of these prickly scrapers could be strategically placed in the most polluted areas of a city to have its air cleaned in just a couple of weeks.
The building’s outer cellular structure is comprised of a cluster of spiky concrete units inspired by sea sponges. This tower itself works as a chimney where polluted air can be gathered, filtered and oxygenated by the algae and a specialized water-sprayed system. We’ve seen other types of purifying skyscrapers, and the idea of having an office building or other structure do double duty as filters seems very promising.
