#10 Steripen Adventurer Water Purification
The best eco-adventurer solar gadget is saved for last. The SteriPEN Adventurer is a solar charger, but not for cell phones or iPods. Instead, it provides solar-powered water purification for the avid, multi-day adventurer.
In 48 seconds, the Adventurer creates 16 ounces of safe drinking water using ultraviolet light technology to purify the water. UV energy emitted by light is absorbed by potentially harmful microbes (most notably the bacteria common to creek and river water). The UV energy prevents the microbe from reproducing which prevents humans from getting sick. This simple process destroys over 99.9 percent of the harmful microorganisms found in nature’s water supply. The built-in solar cell charges two CR123 batteries which perform the purification duties.
