The unchecked and reckless human activities give birth to pollution, which has taken massive toll on the environment, and it is getting worst. Such is the magnitude of the problem that the air we breathe is not clean, and there is no one else to blame for it but us.
Fortunately, technologies are being developed and newer ways being enforced to either curb or eliminate this very major existential threat.
One of such technology is the ‘Smog Free Tower’. As the name suggests this massive 23-foot tall air purifier is made for one purpose only, i.e. to help clean up the air and make it breathable again. The purifiers are to be deployed in Beijing, which has been ranked among world’s most polluted cities.
Designed by Dutch designer Daan Roosegaarde, the tower-like purifiers sucks up smog similar to a vacuum cleaner from the top and in return releases filtered air, through its six-sided vents. As per Tech Insider, the device cleans more than 30,000 cubic meters of air per hour and operates on 1,400 watts of green energy.
How does the tower functions? Roosegaarde revealed the working on his Kickstarter page:
"By charging the Smog Free Tower with a small positive current, an electrode will send positive ions into the air. These ions will attach themselves to fine dust particles.”
“A negatively charged surface – the counter electrode – will then draw the positive ions in, together with the fine dust particles. The fine dust that would normally harm us, is collected together with the ions and stored inside of the tower. This technology manages to capture ultra-fine smog particles which regular filter systems fail to do," he added.
But that’s not all the device air purifier doesn't just clean up smog, it can also be used to make fine jewellery.
Yes, you heard it right the fine carbon particles collected by the tower can be condensed (changed from a gas or vapour to a liquid) to create tiny ‘gem stones’ that can be used as jewellery pieces, reported Science Alert.
