Imagine it; you walking down the street with your mobile phone in your hand and then all of a sudden… Zap! your phone gets blasted with a laser to give it a boost of power.
I know wireless charging at distance is already something that is being looked at but I love the idea of visable laser beams being fired around all over the place charging up people’s stuff.
It may only be an tiny RoboFly but this is basically what the university of Washington are about to be unval at the international conference of robotics. A Robotic fly no heavier than a toothpick being powered by a laser blast.
