So…I was playing on my computer one night while my girlfriend was watching some obscure cable channel. Suddenly she exclaimed, “I wonder if that would work with pee?” She had just watched an ad for the Hydralight — a water-powered flashlight.
Needless to say, she got my attention. There it was, a typically melodramatic commercial for a water-powered flashlight. Not as cool as if it was named for a dragon with a bunch of heads, but maybe there’s a reason they didn’t call it Hydrolight.
So…my curiosity was piqued, so I jumped on Amazon to find it. I figured 30 bucks, what the hell, it’s worth that to check out a flashlight they say doesn’t need batteries, nor to be plugged in. And one that in worst case maybe I could charge with my own urine if need be!
So…within a few I received my Hydralight and tried it out. I even followed the directions! The Hydralight comes with a plastic cell you dip into water. They say you’ll get 300+ hours out of one (revolutionary fuel!) cell and several dips of water – we’ll see how correct that claim is, and if it will run on water collected in the field, i.e. will it work on water that isn’t as filtered as what comes outta the sink?
So…I’ve only had it a couple days, but so far I can say this. It isn’t the brightest light, but it will definitely help out in a pinch. I did have to rehydrate the cell once already after it sat for a week with minimal use.
I’m camping this weekend and plan on using it as much as possible to see how it does. I’ll follow up with more.
Recedite, plebes! Gero rem imperialem!
