There's a lot of fun to be had ridiculing nature-loving hikers for their high-tech gadget addictions, but ultimately devices like the PowerTrekk are an absolute good. In the short term, they enable an easy way to recharge life-saving navigation and communication technology in the wild. In the long term, they might just push the technology along to the point where hydrogen fuel cells provide the world with a truly clean alternative power source.

Plus, how awesome is it that any watery liquid will do. Beer, urine, drinking water, scummy water -- it's all good inside the PowerTrekk. I'm not so sure about blood, however. I suppose that's going too far, even for one more round of Words With Friends.
