|The Soladey J3X Toothbrush|
The Solar Powered Toothbrush has been in the development stages for over 15 years by the Japanese company Shiken at the University of Saskatchewan by Dr. Kunio Komiyama. The Soladey J3X Toothbrush features a solar panel which sends electrons thus causing a reaction with chemical in the mouth that clears away plaque, which in turn has the potential of eliminating toothpaste. The only disadvantage the toothbrush will not work in the dark, but utilizes light that also generates a solar powered calculator.
