Now, I was all set to get excited about the idea of wireless power (which would, after all, be really really cool) when I saw this sentence:

Although the team has not built and tested a system, computer models and mathematics suggest it will work.

Never mind then, eh?

Wasn't that Tesla's idea in the old days?

Strange that they don't really deal with the possible effects on humans/animals of having electricity floating about the place.

Considering the fuss that people make over the use of mobile phones and their transmitters in heads/pockets and in built up areas, I can't really see this one going down to well with the populous at large (even if it can be done)...

Actually that is mentioned in the BBC article. It says that people, etc. don't resonate with signal, so they don't receive power from it.

What they mean is that the coupling will be negligibly small. I'm not convinced, myself. And there are other potential effects than bulk energy transfer, from being in an oscillating magnetic field.

We'll just have to try it and see. It might prove perfectly safe, just like MRIs seem to be (at least for short term exposure).

Pretty similar, yes, although Tesla wanted to build large towers to power whole town, and the signal was much less carefully analysed and tuned.
