The BBC has posted this about an innovative type of glass that is in the final for a prestigious engineering award.

The Pilkington Activ glass has a special nano-scale - extremely thin - coating of microcrystalline titanium oxide which reacts to daylight.

This reaction breaks down filth on the glass, with no need for detergent. When water hits it, a hydrophilic effect is created, so water and dirt slide off.
