Does it belong in Travel Technology or OMNI? Let the moderators decide.
Imagine needing to use your cell phone, but the battery is dead. So you look for an isolated spot and recharge your cellphone. Even better, if the technology can be harnessed to do that, you find your car battery is dead and you are late for work. You pop the hood up and.........there you go. Got enough juice to get your car going, after you have gone, of course.

Would be quite useful. Out of power in the woods? Boil some water and NATURALLY replenish power supply a few hours down. Morarji Desai would be proud.
