Soladey Solar Powered Toothbrush ($22 @ Amazon.com)
We don’t usually store our toothbrush outside on the lawn, but with Dr. Kunio Komiyama’s Soladey-J3X solar toothbrush, we may start. Charge up this futuristic cavity fighter and Komiyama says you can brush your way healthy without toothpaste at home, and without relying on unsafe water sources when you’re camping, out of the country, or in a post-apocalyptic hellscape. The brush heads are replaceable and the body, available in six colors, is designed to last “a lifetime.”
