More and more urban environments are growing at a rate that is virtually unsustainable, as far as emissions are concerned. This is particularly prevalent in emerging markets such as China, Brazil and India – where city smog is now a public health concern.

The World Health Organisation counts around 3 million deaths per year worldwide due to air pollution.

Dutch artist and innovator Dan Roosegaarde might be the hero of the day. He has designed a series of products to help tackle the growing problems facing us that stem from pollution. He is the man behind the 23-foot-high towers that essentially operate as a massive air purifier.

Since then, he has unveiled a concept bicycle that cleans polluted air while the rider pedals.

HOW THE MAGIC BICYCLE WORKS

The invention works by sucking the polluted air through the front of the bike, cleaning it through a filtration system and then releasing the fresh air, all during the ride.

So far various factions of the Chinese government, who are pushing to become global leaders in green technology, now that the US has seemingly given up this quest, have supported the idea.

The potential implications could be enormous, particularly in urban environments where the cycle lanes are interwoven with the grid, such as in major cities like London, New York, Berlin, Buenos Aires, and Beijing – where bike sharing programs are on the rise.

“Beijing used to be an iconic bicycle city,” said Roosegaarde in a statement. “We want to bring back the bicycle — not only as a cultural icon of China, but also as the next step towards smog-free cities.”
