If you’re a camper, or you just hold a paranoiac’s distrust for your local water system, you may be interested in getting your hands on a CrystalPur water filter.
Invented to help starving families out in Africa from dying of thirst, this tiny unit can actually process six liters of water per unit per hour. Most of a bag of charcoal into this thing and you wind up netting fully seven thousand gallons of purified water.
There’s no word on when or where these will be available for sale, or even if regular schmoes like us can get our hands on it. But if you’ve ever wanted a fast and easy way to purify huge quantiites of water, then you may just have it after all.
