Tiny hair on home surfaces: They are curved so that when they turn the top always goes in about the same direction. Spin them from the unexposed side with electrical current, air flow, or something more improbable. If something heavy is put on them the force turning them is weak enough that the torque doesnt break them. Good for carpet replacements, countertops, eating cookies in bed, and so on.-- Voice, Apr 11 2007 Wouldn't this only move the dust particles a maximum of one turning turning diameter along? I guess if you cascaded the movement of adjacent hairs (like a mexican wave) then you might achieve something different, although I'm still struggling to see how this is self cleaning.-- Texticle, Apr 11 2007 Hairs or particles? This is really poorly thought out.-- daseva, Apr 11 2007 Why not borrow from the geometry of lung surfaces, and whip your little hairs in the same direction? Turning doesn't sound ideal.-- Worldgineer, Apr 11 2007 random, halfbakery
