You may remember PowerWINDows, a project that involves putting metal structures between skyscrapers to act as wind turbines. Now imagine a different twist on the same idea -- a skyscraper with a straw lampshade-like cover on its top that can harvest wind energy.
This is the idea behind Strawscraper, the invention of Swedish architecture firm Belatchew Arkitekter. The project aims to extend a building in Stockholm called Söder Torn with an energy-producing outer shell made of piezoelectric straws that can recover wind energy and also add a new look to the building.
Indeed, though wind turbines generally are found in rural areas, innovative designers are now looking for ways to harness the skyscraper canyons of cities -- where wind swirls and often gets trapped between buildings -- to provide this type of energy in urban areas.
