Water that looks good enough to drink can still present a problem. As we noted back in October, there is a way to help make the water a little safer to think while on the go. The SteriPEN Freedom is a handy gadget that can be used to “zap” water and make it safe by killing bacteria or viruses. The battery-powered wand-like device emits UV light that will destroy bacteria, viruses and protozoa, and is actually just a scaled down version of what is used to treat mass quantities of water already.
A dedicated outdoors enthusiast Miles Maiden, had been studying the uses for solar power, and noted that UV technology had been used for more than 100 years. In 1997 he founded Hydro Photon Inc. and created the first SteriPEN. At $120 it isn’t cheap, until you realize how many bottles of water you might buy while traveling, and more importantly can be used when there is no convenience store in sight. We also bring it up again as it has been garnering lots of media attention this holiday season.
