We’re always looking for new ways to charge our mobile gadgets. Wind, sunlight, fuel cells, you name it. These all seem to rely on an external device pushing power to a rechargeable battery. However, what if the charging mechanism was built into the battery itself? That’s the idea behind this wind-up Charge Batteries.
Yes, I did just say wind-up batteries, and it’s exactly what you’re thinking. Imagine a AA battery that you can wind in order to generate a charge. Do your fingers hurt yet? I’ve had hand-cranked flashlights before, and I remember how long it took to get even a few minutes worth of light. Can you imagine twisting a pair of tiny batteries for extended periods? Something tells me that this concept will never be turned into reality.
