What if instead of needing a cell phone charger to keep your phone powered up you could eliminate the cell phone battery altogether and use the wind, or even your heartbeat to keep your phone powered up? According to people a lot smarter than me, that is going to be entirely possible within the next 5 years. Researchers have developed a new technology called nanogenerators (really teeny tiny generators) that can generate electricity from very small movements – like a heartbeat. The technology can already produce enough energy to power a LCD screen or send out a radio signal but not both at the same time. But those same researchers are confident that they will be able to augment the power of these nanogenerators fairly easily, and expect the technology to find its way to store shelves within the next 5 years. I can only imagine how fast your phone will charge up if you are out jogging on a windy day.
