DE-FOGGING IN WARMTH

A WAY OF PRECIPITATING WATER OUT OF THE ATMOSPHERE TO ELIMINATE FOG, CLOUDS AND EVEN PENDING HAILSTONES HAS BEEN PATENTED BY RESEARCHERS OF THE DOW CHEMICAL CO. CONVENTIONAL PROCESSES, SAYS DOW, REQUIRE THE SUSPENDED WATER DROPLETS TO BE BELOW FREEZING. THE DOW PROCESS, WHICH USES A SPRAY MIXTURE OF HYDROGEN SULFIDE AND ONE OF FIVE OTHER CHEMICALS, WILL WORK IN TEMPERATURES UP TO ABOUT 70 DEGREES F. ALSO, THE COMPANY SAYS, THE SPRAYED CHEMICAL DROPLETS COMBINE WITH THE WATER DROPLETS MUCH MORE READILY THAN DO SOLID PARTICLES COMMONLY USED. /ARTICLE/
