Bumpy Surface of Lotus Leaf Inspired Building Materials

The bumpy surface of a lotus leaf (computer graphic close up view below-left) acts as a self-cleaning mechanism allowing dirt to be cleansed off the surface naturally by water, for instance, during a rain shower. Even the smallest of breezes on the plant causes a subtle shift in the angle of the plant allowing gravity to remove the dirt without the plant having to expend any energy. This same idea has been applied to the design of new building materials such as paints, tiles, textiles, and glass that reduce the need for detergents and labor and also reduces maintenance and material replacement costs.
