Japanese toothbrush goes solar

  • The Shiken company of Japan is field testing a funky solar-powered toothbrush that doesn't require toothpaste.

    Instead, the Soladey-J3X - designed by Dr. Kunio Komiyama and Dr. Gerry Uswak - features a solar panel at its base that transmits electrons to the top of the toothbrush through a lead wire.

    As PhysOrg explains, the electrons react with acid in the mouth, creating a chemical reaction that breaks down plaque and kills bacteria.

    Researchers have already tested the toothbrush in cultures of nefarious bacteria that cause periodontal disease.



    The result?

    Well, the solar-powered brush reportedly caused "complete destruction of bacterial cells."

    So how much power does the Soladey-J3X consume?

    Not much, according to Komiyama, who says the device sips approximately the same amount of juice as a solar calculator. 



    Sounds good to us!

    Now, if they can just replace those annoying dentists with solar-powered robots!
