Bangkok Fights Air Pollution With Water-Spraying Drones (qz.com)

An anonymous reader quotes a report from Quartz: Earlier in the week, levels of PM2.5 -- tiny particles 2.5 microns in diameter or smaller that can penetrate deep into the lungs -- reached 185 micrograms per cubic meter. Anything above 150 is deemed hazardous for all individuals (50 or below is considered good). The government has responded by unleashing a small fleet of drones that can spray water into the air and eliminate some of the pollution. Photos from a test on Tuesday (Jan. 22) show the yellow aircraft dispensing water and a "non-hazardous chemical spray," reported the Bangkok Post. An official from the Defense Technology Institute, a government agency, said the test, in which drones sprayed for less than an hour, reduced the concentration of PM2.5 by 10 micrograms per cubic meter on average.

    Why don't they attach the water sprayers on buildings? It seems like it can only be more expensive and less fuel efficient to actually get the water airborne before spraying it into the air. A water hose on a building can also operate continuously without needing to refuel either water or battery.

    Apart from that the idea is actually good. Air pollutants have a tendency to stick to rain drops and fall down to the ground with the rain. In this case it's artificial rain. The question is where the water comes from, like is it sea water, in which case salt will get on to the ground and cause issues. Is it drinking water?

    I was in an office some years ago and they were forced to have some piece of art (tax money has to go somewhere) and at first the workers were like "why would we want that thing?". However it was an artificial waterfall, meaning it cycles water through it at all time. Eventually they were actually really happy about it because the constantly falling water caught all sorts of dust particles and similar from the air, meaning the air in the office ended up being much better. They still didn't look at it though.
