Air quality is equally important for a 12-year-old English girl whose mother has asthma.
She developed a rucksack which filters polluted air, incorporating an air filter and ventilators onto the front of her fashionable design.
The system is powered by solar panels and a dynamo. Her invention was the prize-winning entry in a competition that called on children to combine fashion and science.
The rucksack is now on display in the competition sponsor’s flagship store, serving as inspiration for future innovators.
Thanks to another designer, meanwhile, cycling can help tackle air pollution too.
