Smoggy China Gets Air-Purifying Bicycles

It’s time for China to kiss face masks goodbye, because ofo has just come up with an even better solution for the smog-infested country. Partnering up with TEZIGN, ofo has developed a high-tech bicycle that cycles and purifies air, soon to be available to 20 million people.

The bicycles work similarly to Roosegaarde’s Smog Free Tower by providing “a healthy and energy-friendly solution for urbanites, combatting both traffic congestion and pollution issues in the city.” Both the Smog Free Tower and the smog-free bicycles are part of Roosegaarde’s larger vision to fill cities with fresh air.

The project is currently being productized in China and the Netherlands. The eco-bike is not only a huge breakthrough in China’s air pollution problem–it is also reviving a centuries-old bicycle culture.

“Beijing used to be an iconic bicycle city. We want to bring back the bicycle as a cultural icon of China and as the next step towards smog free cities.”

Looks like China can now bid jars of air adieu.

One Tree With The Power Of Hundreds

Want to save the world? Plant more trees. While it is perfectly good advice, it’s an exhausted tirade–hardly anyone does it. So should we give up? German startup Green City Solutions, which has recently come out with the CityTree, certainly doesn’t think so.

The CityTree is not a tree per se, but actually a densely packed moss culture, vertically housed in an unit that blends in with its urban surroundings.

In an area of 3.5 square metres, the CityTree does the equivalent job of 275 trees of filtering the air of fine dust, nitrogen oxides and carbon dioxide.

Now that’s impressive. But why use moss? And how exactly does the CityTree work?

“Moss cultures have a much larger leaf surface area than any other plant. That means we can capture more pollutants.”

The installation powers itself through its solar panels, and rainwater is collected and automatically redistributed using a built-in irrigation system. Sensors can be added so that data can be collected on the CityTree’s performance.

The CityTree also serves as an analog billboard, if its environmental functions haven’t impressed quite enough. Units have been installed in Oslo, Paris, Brussels, and Hong Kong, with plans to expand to India and Italy, as well as the Americas.

Now, if only I could fit a CityTree in my apartment.
