Wow. Comments I agree with. Tesla was a genius, people claim health problems from anything. and this would indeed revolutionize the world.

And the best 'Let's get it working first.' is correct.

That was not sarcasm. I do agree with those comments.

Reality Check: Everything described in the article works and has been shown and known to work for decades. And has been largely useless.

I qualified 'useless' because any technology can find a niche use in one place or another.

But there is some hope. Refinements have slowly been made and more niches found where these broadcasting power is worthwhile. For the ordinary consumer they may soon be powering a few very low power devices.

And very low power devices keep coming. Each new model of anything electronic seems to require less power. The trend will continue as nanotechnology becomes common.

I'll make a guess that this may have some appeal to the auto industry. Much of the gadgetry in vehicles requires very little power to control but a huge number of wires is used to carry those signals. The wire harnesses are expensive to make, tricky to install, hellish to repair, and have a definite weight automakers would love to be rid of.

And interference should be controllable. A car is already a Faraday Cage in many respects. Preventing these incredibly weak signals from causing mischief outside shouldn't be hard.
