"Treatment makes surfaces self-cleaning" I read this article, a few weeks ago http://www.engineerlive.com/european-design-engineer/instrumentationelectronics/17068/treatment-makes-surfaces-selfcleaning.thtml [Broken] Do anyone know more about this? Can it actually be applied to metal? i.e. car body, so I won't have to wash my car ever again:!!) , I'm just kidding, but wouldn't that be great.
