  1. Sustainability Problem: Air pollution in cities causes respiratory and cardiovascular diseases as well as premature death. Category: Health
  2. Possible tech solution: Smog Filtering Tower.

  • The City of Rotterdam in the Netherlands was the first in the world to open a smog-free tower.
  • The vacuum-cleaner like structure is seven meters high. It sucks in dirty air, filters it using Ion technology, and return clean air into the atmosphere.
  • Every hour, the tower can clean 30,000 cubic meters of air.
  • Verification tests have shown that the tower improves outdoor air quality by up to 60%, and indoor air quality (such as in parking garages) by up to 70%.
  1. Organizational Stakeholders: Citizens in highly polluted cities, local environmental organizations, private Genentech companies, municipal departments of environmental protection, local political leaders.
  2. Steps in deploying the technology:
    • Obtain political buy in from local stakeholders
    • Secure financial support (can be PPP that brings together local public and private organizations)
    • Design smog filtering tower that meets specific needs of the interested city (size, aesthetics, location, etc.)
  3. Comment on “Elevated bike path concept to fight congestion” by Pablo Mandiola

The proposed technology does not make cycling safer, as mentioned in your post. In fact, regular bicycles would not be welcomed on the proposed elevated lane network, as it is designed to accommodate electric bikes, scooters and other two-wheelers that BMW manufactures.

While the idea is interesting, if the ultimate goal is to reduce GHG emissions and promote low carbon transportation methods – we should be reducing paved road miles and not increasing them. Rather than building an additional road network, I would propose re-purposing vehicle lanes into bike and public transportation lanes, which would reduce the need and convenience of private vehicles on roads and reduce emissions from transportation.

  1. 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.
