Batteries Not Included: Cell Phone Powered By Light And Radio Waves (Video)

Alright. I will tell you from the start that this is NOT going to be anywhere near as badass as your super-duper-smartphone. But if you spend your time picking at what this cell phone cannot do, you will miss appreciating the glorious technological step forward it represents. The holy grail of power systems is developing a perpetual motion-driven energy source (does not exist), but a very acceptable step down from that is powering things with virtually limitless source energy (like solar). BUT… what if we took a half step down and eliminated the need for a power source altogether? THAT is where THIS is going!

Researchers at the University of Washington have created a cell phone that uses so little power, it never needs to charge and doesn’t have a battery. Instead, it pulls power from ambient light and radio waves.
