Some great benefits of driving a motorcycle are many, however let’s simply point out right here that, by selecting a bicycle to maneuver round, you don’t add to the air pollution, you get a exercise (sure, even on an e-bike) and you continue to have time to get pleasure from your self. You can quickly add one other profit to this record, one that will prime all of them: by biking, you can be actively offering recent air to your fellow city-dwellers.
The thought of utilizing a bicycle to actively filter air and coimbat pollution on the go isn’t new, having been used for a number of ideas earlier than. This time, although, it’s not a bicycle that’s doing the filtering, however a really particular wheel, the ROLLOE.
ROLLOE is the creation of commercial designer Kristen Tapping from London, UK, and has already been acknowledged with the Design Innovation in Polymer 2020 award. As Tapping reveals in an interview with RedBull from final month, she is now engaged on the third prototype, however she already has two practical ones and the idea laid out. She goals to safe funding and see this go into manufacturing within the subsequent 18 to 24 months.
ROLLOE is a three-spoke magazine wheel with two hubcap-like attachments, that sits within the entrance of the bike and weighs simply 1,050g (2.3 kilos). Between the wheel and the hubcaps, there are three totally different filters and fins by way of which filtered air can be pushed out. Filthy air is sucked in by way of the central gravity by centrifugal pressure and pushed out by way of the fins. In concept, Tapping explains, the more durable you pedal, the extra air you’re capable of purify.
The obvious benefit is that you just get to do it smack the place it’s most wanted: in crowded areas, the place there’s heavy visitors.
The machine makes use of three sorts of filters for optimum effectivity: Loofa sponge for giant particles, HEPA for PM2.5 particles, and activated carbon for fuel molecules, VOCs and odors. This is able to make it appropriate for pollution like PM10-2.5, Ozone O3, CO2 and NO2.
Tapping received the thought whereas driving by way of London and experiencing for herself the exhaust fumes, the warmth coming off and the mud. She estimates that, if as little as 10 p.c of London cycles used ROLLOE, they might filter 20 instances the scale of Trafalgar Sq.. Or, talking in numbers, if Santander bikes utilized in 2018 had had ROLLOE, they might have produced 79,865 m3 of fresh, filtered air.
Tapping is concentrating on the bicycle ride-sharing corporations first with this invention, however she has plans for privately owned bikes as nicely. Santander or Mobike fleets may use ROLLOE and encourage cyclists to pedal extra by monitoring their progress and their location, by way of a wide range of rewards. For privately owned bicycles, TfL (Transport for London) may step in and pay for the machine itself and common upkeep, as a way to get extra house owners to have the wheel put in as a substitute of the common one.
Talking of servicing, the filters can be washable and the wheel would require upkeep as soon as per week or each 250 km (155.3 miles) for fleet-owned bicycles. Every fleet operator may use the app to see when upkeep is so as, and take the bike to a neighborhood bike store for disassembly however clear the filters elsewhere.
If Tapping secures funding and the ROLLOE goes into manufacturing, she’s additionally contemplating creating an analogous rear wheel (which is trickier due to the drivetrain), varied sizes for the present one, and even totally different colour schemes. However as it’s proper now, this undertaking is extremely promising and theoretically capable of render the greenest technique of transport really carbon-negative.
