¿No creen que pueda haber cosas que se limpian solas? ¿Que puede haber edificios que no necesiten limpiearse nunca, o prendas que se sacudan la suciedad? Lean este GENIAL artículo del Scientific American:

Link: Self Cleaning Materials

• Microscopic bumps on a lotus leaf transform its waxy surface into an extremely water repellent, or superhydrophobic, material. Raindrops roll easily across such a surface, removing any dirt.
• Researchers have developed synthetic self-cleaning materials, some of which are based on this “lotus effect,” whereas others employ the opposite property—superhydro­philicity—as well as catalytic chemical reactions.
• Future products may combine the two water affinity properties or use substances that can be switched back and forth to control the flow of liquids through microfluidic components.
