National Capital launches Smog Tower!
- ByStartupStory | October 2, 2021
The Indian capital of New Delhi launched a “smog tower” in an attempt to purify the air in the world’s most polluted capital city, but experts are sceptical that it will be effective. The 82-foot tower sucks in dirty air from the top, filters it and then pushes it out from the bottom. The reports describe the radius of the tower to be 0.4 square miles and its filters have a capacity to filter out 35,000 cubic feet of air each second. According to reports from IQAir, a Swiss organisation that measures air quality levels recorded that New Delhi has been the world’s most polluted capital for the past three years. PM2.5, tiny airborne particles that cause inflammation in the lungs and respiratory system and can lead to significant health concerns, are used parameters by IQAir to assess air quality.
According to IQAir, New Delhi’s air often surpasses PM2.5 acceptable levels by up to 20 times, and experts estimate that the city will require at least 213 smog towers to address the problem. Though some have slammed the pollution towers as a waste of money, that diverts attention away from what they believe is the real solution – reducing emissions. “Let us just be clear: this is pointless, a complete waste,” Karthik Ganesan, a research fellow at the Council on Energy, Environment, and Water, told AFP.
