What it's about:
Engineers have come up with a novel solution to curb pollution levels in India, which are among the highest in the world.
They have invented the first-ever device that can catch exhaust fumes from diesel generators and turn them into ink, Reuters reports.
Their device captures up to 90 percent of soot particles from diesel exhaust, preventing the polluting emissions from entering the atmosphere.
The engineers, who work for the company Chakr Innovation, said the device has already collected over 500 kg of soot, which has been used to create more than 20,000 litres of ink.
Why it's noteworthy:
The new device is a welcome invention for India, a country that has 14 of the world’s 15 most polluted cities, according to the World Health Organisation.
Around 1.1 million people in India die every year from the impacts of air pollution, accounting for around a quarter of total deaths from that cause worldwide, a 2015 survey by the U.S.-based Health Effects Institute found.
The Indian government has set an ambitious target of generating 175 gigawatts (GW) of energy from renewable sources by 2022, which should help reduce sources of air pollution.
Last year, the country’s renewable energy capacity exceeded its capacity from coal and other fossil fuels for the first time - a significant milestone considering its dependence on coal reserves.
