It will also feature driver-controlled and autonomous operation modes. The car will have a flexible interior so it can be reorganised to be used as a dining or sleeping space. (Dezeen)
Why does this matter?
Air quality is pretty terrible in urban areas around the world. City air pollution levels worldwide are on average around four times higher than those recommended by the World Health Organization, with the highest levels recorded in cities in Pakistan, India, Bangladesh and China.
In Europe the picture isn’t much better. Historic policies to promote diesel vehicles – themselves ironically aimed at reducing CO2 emissions – have resulted in (predictable) declines in air quality in many of the continent’s cities.
This poor air can have significant impacts on human health – many of which are still not fully understood. Analysis suggests 160,000 premature deaths in Shanghai, Tokyo, Dehli, Mexico City and Sao Paulo in 2020 alone were the result of particulate matter (PM) air pollution. On top of this, research has linked air pollution exposure to dementia, and it has even been tied to depression.
Heatherwick isn’t the only architect and design studio attempting to grapple with the problem – building designs are adapting to mitigate or dampen the effects of bad air.
How does it work?
The Airo concept (not the first time Heatherwick has stepped into vehicle design) is electric, so it will have no tailpipe emissions, and it will be fitted with the HEPA system on its undercarriage to “vacuum” PM from the air as it travels. While it’s not clear whether the system will use power to filter air, HEPA filters are effective in trapping PM. They don’t, however, clean other air pollutants like nitrogen dioxide – though advanced filters can do this – so Airo may only tackle part of the problem.
Mobile air pollution solutions
While a host of stationary objects have been designed to improve city air, and the humble tree does a good job, other methods to tackle the problem on the move are being utilised. As we highlighted last week, Voi has launched an e-scooter with air-pollution sensors that can help users avoid pollution hotspots. City traffic managers can also access the scooters’ data to inform measures aimed at improving air quality.
Elsewhere, in Salt Lake City, researchers have installed sensors on trains to monitor air quality and CO2 emissions as they move across the city.
So that’s it, we switch to vacuum cars to drive around in and all is good?
Not really. Transport is just one part of the picture and to tackle air pollution at source cleaner fuels and electrification will need to be deployed in buildings, as well as across the vehicle fleet. This will take time. What’s more, while EVs don’t have tailpipes that contribute to air pollution, their tyres and brakes do add to the problem – and research suggests these sources can be significant. Engineers are looking at additional ways to tackle that problem too.
