French scientists are testing temperature sensitive paint for use on the highways as a visual warning for drivers in icy conditions
A new temperature-sensitive varnish developed by researchers at French company Eurovia can be applied to road surfaces to warn drivers about dangerous conditions. The technique – still at the testing stage – might help prevent ice-related traffic accidents in future, the researchers say.
I love ideas like this. So simple, yet brilliant. This will likely save lives if used in climates conducive to black-ice.
