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.

Japanese toothbrush goes solarResearchers 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!
