You'd need 2-way communication for that to work, yes?

The background picture in my profile is one I took myself. It's taken at Niarbyl in the Isle of Man, and is looking south-west along the coast. It's a splendid place, though it tends to be a bit… bracing most of the time; the picture was taken on one of the rare relatively calm days.
I do software engineering to support scientists at a research university. I get to work with a lot of fields and see many (usually small) WTFs. I also write software for fun. There's a really good chance you're using something I've written right now and you don't know it. That pleases me a lot.
I don't know about you, but to me, those figures don't match up with the inverse square law. And then you factor in the inherent losses in any wireless transmission, and you realise that not only is that thing spewing out huge amounts of RF (who knows what it's interfering with?), it's also wasting equally huge amounts of power.
I wonder whether they plan to do tricks like those that are used in cellphone towers, which most certainly do not broadcast the same amount of power in all directions. Instead, they use clever antenna design and some neat signal processing to effectively beam the signal just towards interested receivers (and without strong the inverse square fall-off because the beam is much tighter). I don't know if the same thing would work with power transmission, but maybe?
Looks like your connection to What the Daily WTF? was lost, please wait while we try to reconnect.
