Dutch artist Daan Roosegaarde has come up with an innovative plan to tackle Beijing’s air pollution problem. After a pilot in Rotterdam, the Smog Free Project is coming to China. The project consists of two parts. First, a 7m tall tower sucks up polluted air, and cleans it at a nano-level. Second, the carbon from smog particles is turned into diamonds. The towers suck up polluted air, and clean it, releasing it back into parks and playgrounds. And according to Roosegaarde, these areas are 70-75% cleaner than the rest of the city. The other aspect of the project will see the captured smog transformed into diamonds. 32% of Beijing’s smog is carbon, which under 30 minutes of pressure can be turned into diamonds. The money raised by jewellery made with these diamonds will go towards supporting the development and building more Smog Free towers. https://www.weforum.org/agenda/2016/06/why-turning-smog-into-diamonds-isn-t-as-crazy-as-it-sounds
no details on how the carbon is converted into diamond. i suspect this is a 'ruse' to obtain funding.
Not quite sure about any "Diamonds"... However, the artist's "Smog Free Project" has produced "Jewelry" of sorts... : http://hyperallergic.com/236836/a-23-foot-tall-air-filter-is-turning-rotterdams-smog-into-jewelry/
