SteriPEN Portable UV Water Purifier
Pocket-size lightsaber zaps bacteria, making risky water potable.
Cruising sailors who venture to the fringes of civilization, or to attractive but perhaps unsanitary foreign ports, or even to unfamiliar marinas, often have reason to view the sources of their drinking water as dodgy. Unless theyíre willing to carry bottled water or have a watermaker on board, they catch as catch can, and sometimes what they catch isnít any fun. Boiling water and adding chlorine or purification tablets is a standard way of dealing with potential drinking water problems, but sailors may also want to consider a simple, relatively inexpensive gadget that trail-hikers, mountaineers, and other land-oriented adventurers have known about for the past few years. The SteriPEN, one of Readerís Digestís 2007 "25 Products That Will Change Your Life" and Wiredís "25 Gotta Have Gadgets of 2008," kills water-borne viruses, protozoa, and bacteria with ultraviolet light, wrecking their DNA.
