A third-year English design student has “very simply” installed a four-layer air purifier on a bicycle wheel, allowing cyclists to clean up air pollution in any city where they ride.
Called Rolloe, the filter could purify more than a quarter of a million square meters of air if only 10% of London cyclists put it on their front wheel.
Armed with the basic understanding that pedaling a bike creates kinetic energy, all she had to tap to make her dream come true was to find a way to channel dirty air on one side and expel clean air on the other.
Existing filtration technology already uses fans and turbines to force air through filters, similar to a bicycle wheel. Once the final design was finished, he put in a four-layer activated carbon, washable HEPA, and luffa filter to clean out tiny particles and harmful gases like CO2, NO2, and ground OZONE.
With a basic but eye-catching design, Rolloe is implementing all the infrastructure it needs to make filter replacement sustainable.
“Through an in-service collection / mail service, used filters are sent back to Rolloe for washing, while clean filters are changed.” Explain the designer on his website.
Rolloe won Kristen Seizing the 2020 Design Innovation in Plastics award, and is now gearing up for a massive market launch in 2022. How much it will cost is not yet known.
You want to reward the people who ride the bike the most with cleaning credits. A companion app would track your cycling data, allow you to set goals and track your credits, and she hopes to convince local restaurants or shops to accept Rolloe credits as a form of reward points.
Finally, the Rolleo can be manufactured in bulk using a simple injection molding and a 3D printer, while the filters will be recycled at the end of their useful life – it seems the perfect product for the ‘circular’ economy.
