Smart glass reacts to the weather

LONDON, England (CNN) — Scientists in London have created a coating for glass, which reflects or absorbs heat, depending on the temperature outside.

Professor of inorganic and materials chemistry, Ivan Parkin, and Troy Manning, both of the chemistry department at University College London, developed the intelligent window coating as part of Mr Manning’s PhD studies.

The thin film is made out of a material called vanadium dioxide, and it undergoes a change depending on the weather outside.
