(Phys.org) —File under Big Idea. Use a city building to trap pollutants, clean the air, and convert car emissions into biofuel? An architect has such a concept. The idea is to attach a special carbon fiber and steel structure to London's BT Tower, one of the city's tallest buildings. The structure could suck up pollutant particles like a vacuum cleaner. The process would involve "harnessing advancements of various particle-capturing technologies," according to a report in Dezeen, and this process would also involve extracting the carbon from fumes and using it to produce a sustainable biofuel.
