Engineers have released plans for a 5-km-high skyscraper that eats smog

Arconic, a materials science company, has envisioned a 3-mile-high (4.8-km) skyscraper built from materials that are either in-development or have already been brought to market, including smog-eating surfaces and retractable balconies.
