Spiderweb-Like Tower Would Harvest Air Pollution in London and Turn It into Biofuel
by Carl Franzen (The Verge) …Chang-Yeob Lee of the Royal College of Art wants to radically transform London’s BT Tower at some point in the future, equipping it with exterior carbon fiber and steel rigging, designed to capture and convert air pollution into sustainable biofuel, Dezeen reported.
The BT Tower is one of the city’s tallest buildings at 581 feet, giving it an ample position to collect soot and other fine particles and trap them, as well as carbon dioxide emissions. The rigging would also contain titanium dioxide nanotubes, which have a demonstrated capacity to turn carbon dioxide into natural gas by using water and sunlight. Lee’s system would specifically be used to produce methanol on the order of 100 metric tones per year. READ MORE and MORE (DeZeen)
