China’s air pollution problems are well documented and numerous, so the government has announced plans to tackle the problem with a unique solution. Not by cutting emissions (because that would be too obvious), but by utilizing drones to break up the stifling smog with chemicals.

Smog-clearing operations have already begun with the state-owned Aviation Industry Corporation of China using parafoil drones to release chemicals that will enable air pollutants to fall to the ground. These drones have a paragliding wing that can carry three times more weight (up to 700kg) than the fixed-wing version.
