Interesting Invention - Frost Free Glass

A timely invention has been announced in Germany, a car windscreen that doesn't allow ice to form on it.

(Developed at the Fraunhofer Institute for Surface Technology (IST) in Braunschweig, in north-central Germany, the windscreen prevents ice forming even at temperatures as low as minus 18° C. There's only one problem, the thin coating of indium tin oxide applied to the window, can interfere with radio and mobile phone reception. I wonder what everyone will do with those extra minutes on a frosty morning?)
