There is lots of talk about green buildings, but what if they were actually green?
ecoLogicStudio, a London architectural and design firm created a 430 ft sq. gazebo called the Urban Algae Folly at Expo 2015. The Folly produces oxygen and absorbs considerable amounts of carbon dioxide with algae-filled plastic serving as a living 'skin'.
The Folly is made of ethylene tetrafluoroethylene (ETFE), a transparent plastic material. Its hollow interior is filled with water and spirulina, a type of algae often used as a dietary supplement. The growth of the algae depends on sunlight and temperature.
Algae and other marine plants make 70% of the world’s oxygen. The Folly produces about 4.4 pounds of oxygen per day and can also suck about 8.8 pounds of carbon dioxide from the air per day. This is compared with a tree which absorbs only about .132 pounds.
Algae has also been used in a number of other recent urban innovations. French biochemist Pierre Calleja created a prototype for a 'smog-eating' street lamp, which uses bioluminescent microalgae to light streets while absorbing carbon dioxide and producing oxygen.
