Spray-on coating could ice-proof airplanes, power lines, windshields
On your car windshield, ice is a nuisance. But on an airplane, a wind turbine, an oil rig or power line, it can be downright dangerous. And removing it with the methods that are available today -- usually chemical melting agents or labor-intensive scrapers and hammers -- is difficult and expensive work. That could soon change thanks to a durable, inexpensive ice-repellent coating. Ref. Source 9a.
