Story

A Nebraska bridge is using 52 slabs of conductive concrete that can heat its surface and melt snow and ice during winter storms. Developed by University of Nebraska-Lincoln professor Chris Tuan, the technology uses steel shavings and carbon particles to carry electricity through the concrete. The system could reduce the need for de-icing chemicals at bridges, airport tarmacs, intersections and other icy areas.
