NASA-Developed Technology May Help Guard Against Icing on Highways
HOUSTON --- Ice detection technology developed by NASA may have future life-saving applications on U.S. highways, alerting traffic engineers of risky icing conditions.The NASA technology is also ready for use in the commercial airline industry to identify when airliner wings need de-icing, according to the Houston Chronicle newspaper. In that application, a sensor on the wing can detect the difference between liquid water and ice. The sensor relies on microwave signals and is linked to a cockpit instrument display. As a result, pilots can tell whether they need to de-ice before takeoff.Phong H. Ngo, a NASA engineer who helped developed the ice-detection technology, said it also has potential to make roadways and bridges safer.
