November 27th, 2007 - Solar toothbrush
This Science new solar toothbrush, which could make toothpaste obsolete, just sounds so very cool.
The only problem is that I do actually often brush my teeth in the dark. Not pitch dark, but I don’t bother turning on a light in the room when there’s ambient light from elsewhere.
I hope it comes with replacement heads. Would be lousy to have throw out the solar cell every 3-6 months.
