Shiken, a Japan-based company has introduced really an amazing gadget or product that uses solar energy. This is nothing but the daily usable toothbrush. Soladey-J3X is the solar-powered completely eco-friendly toothbrush. It does not need toothpaste for cleaning the teeth. It contains a moisture-activated, titanium dioxide rod n the neck. It works by creating a chemical reaction when light hits the rod. When light hits the rod, it releases electrons, which combines with acids in the mouth to help break down plaque. At the base of the toothbrush, solar panel is incorporated which transmits additional electrons through a lead wire. All these actions and reactions helps in the destruction of the bacterial cells.
