The South China Morning Post reports that drones equipped with parasails can carry about 1,500 pounds of the unspecified smog-busting compounds, which are said to have the capacity to cleanse the air in a 3-mile radius.
The vehicles will reportedly spray chemicals that “freeze pollutants,” causing them to fall to the ground.
But environmental advocates warn that such a process would simply coat the city’s surfaces with still-toxic pollutants.
They add that the government is tackling the symptom rather than the root cause of pollution.
China has tested aircraft and fixed-wing drones to spray smog-dispersant chemicals for several years, but found those delivery vehicles to be prohibitively expensive.
