    I was reading about this on Wikipedia a few days ago. I think it's wild that wireless power transmission's roots have been around for almost a century - that Tesla and Marconi and co. were playing around with it waaaay back when - and now it's just starting to come into play.

    I think the one thing that the article doesn't highlight well enough is that these are highly concentrated electromagnetic waves, and that the reason large-scale wireless power transmission isn't readily available is because the higher the frequency and concentration of the EM wave, the closer you approach something harmful to human bodies. (I think I'm getting the approximate science right here; Phy or Llama, feel free to call me if I'm not.)

    BTW, I've always wanted to build one of those Tesla ceiling plates and walk around with a lightbulb that turns on without being connected to anything.
