Giant water cannon won’t kill smog: experts ecns.cn/cns-wire/2014/05-12/113476.shtml A government department in Xian, Shaanxi province, has invested nearly one million yuan ($160,000) in a removable mist cannon designed to fight the citys dirty air, yet experts say the giant sprayer does little to reduce the density of PM2.5, the major contributor to the citys smog, the Beijing News reported on Monday. The Parks and Woods Bureau of the citys Xincheng district bought the machine from an environmental equipment manufacturer in Guangzhou with government financing of 900,000 yuan. The 10-ton machine can spray water a distance of up to 600 meters and 70 meters high. The water goes up as a fine mist and sticks to dust to form larger particles, which fall to the surface under force of gravity.
