Wireless Power

At last, the final cable may be removed. No need to recharge, or if you do, just move to an area with an induction loop and it’ll recharge you devices while they’re in your pocket. As the article notes, Nikola Tesla had come up with this idea a long time back, which is shown, bizarrely, in The Prestige, which I went to see recently.

My favourite snippet about Tesla, and I’m not sure if it’s true or not, or if I’m confused with another scientist, is that he used to spend some of his time at the Golden Gate Bridge with a hammer and a stopwatch trying to find the right resonance to make it collapse.
