Picture it.
You are lost in the woods, you've sprained your ankle sometime yesterday morning and your potable water is about to run out. All because you forgot to plug in your cell phone before going hiking.
There's supposed to be some emergency number that will let you recoup half your battery
life, but you couldn't recall it if your life depended on it.
You are sure of this because, well, your life kind of might depend on it right now and...nothing.
How much pain would you be willing to endure to trickle charge a few bars on that puppy hmmm?
Would you be willing to, say...
...chew on a piece of tinfoil for twenty minutes or so?
If you said something like, "No FREAKING way!" then congratulations!
You were born sometime earlier than the 1980's and have four or five different kinds of metal all squashed together, perhaps even, (joy), held together by mercury stuffed into your molars and you are a living battery capable of generating about two whole whopping volts of electricity if you sandwich a dissimilar metal like tin between your molars.
You could have brought a little wind up gizmo that would have done the same job with much less effort on your part, but you could have remembered to charge your phone too and didn't do that either did you?
Luckily, you did opt for a cell phone with FryCorp's new biocharge system...and remembered that your phone had this feature.
So buck up muffin.
Put the tiny two wire foil charging plate between your molars and start cringing baby as you anxiously wait for those bars to light up.
...on second thought, close your phone.
Tsh!
You're wasting power.
