Lotus Nanotech

Makarand writes "The lotus, a flowering plant native to Asia whose waxy leaves repel water droplets and particles of dirt, is teaching nanotechnologists a thing or two. Scientists at BASF have found that the lotus plant surfaces have a coating of wax crystals around 1 nm in diameter. This roughness on the nanometer scale helps the plant surface to reduce the actual contact area to 2-3% of the droplet covered area making its surfaces superhydrophobic. If the surface is slanting, the droplet rolls off, instead of sliding off, picking up small particles of dirt on the way giving a "self-cleaning" effect. BASF is now working on an aerosol spray to coat a surface with such a self-cleaning nanostructure. The self cleaning shoe might soon be a reality."

    Self Cleaning Pants. It's about to be the year 2003, and we're starting to have the technology for the ultimate pants. I'm talking about the kind of pants that Sci-Fi authors of old dreamed of. We have the Dockers with extra pockets for our gadgets, and the Levis with radiation sheilding. And now with this substance we will be able to make The Ultimate Pants! I see a utopia in our near future where the free people of Earth are released from the slavery of washing their gadget toting pants. Oh the luxury!

    Of course, we can't forget the three biggest conrtributions from nature

    Marijuana - the classic

    The Poppy - heroin, morphine, opium... God's own medicine

    Coca - cocaine. Nature's best stimulant

    Just think of how boring civilization would be if it was not for these three mind alterning substances.

    PS: Yes, so the heroin has some acetic acid, but you could conceivably get that from fermenting some fruit...
