Fogless windshields coming soon

A team of scientists at MIT has developed a polymer coating for glass made of silica nanoparticles that can permanently prevent fogging. Introduced at the 230th national meeting of the American Chemical Society, the polymer coating has already attracted the attention of the military and two automakers. The coating works by preventing the process of tiny water droplet condensing on glass and scattering light in random patterns, which is how fog forms. The nanoparticles strongly attract water droplets and flatten them against the surface into a uniform sheet, preventing light from being scattered. The technology can be applied to many surfaces, including spectacles, which is good news for all you four-eyed freaks out there like me.
