This Toothbrush has Plenty of Power But Needs No Batteries

This toothbrush, simply called Be, which stands for “beyond electric” is the world’s first battery-free powered toothbrush. It stores and is powered by kinetic energy, which is generated while you brush. The simple act of twisting the handle twice delivers the power of 80,000 brush strokes. It also 100% recyclable, features biodegradable brush heads and is made in the U.S.A.
