I'm not all that surprised. It's been coming for years. What concerns me, though, is the potential safety issues. Sure, they say that it's safe now, but what about later? Cell phones were supposed to be safe, too, and now they aren't quite so sure. A lot of things industry has put forth as safe have eventually proven just the opposite.
It's a great concept, and I believe an ultimately necessary one. True energy independence will come when we can collect solar energy in space and beam it down to transformers on the surface, hopefully without incinerating any wayward planes that might stumble into the beam!
The blanket statement, from the article, "It turns out the human body is not affected by magnetic fields" strikes me as very premature. And I would find it very difficult to believe, since the human nervous system is as much electrical as chemical, and either can be influenced by magnetic fields.
I think I'll wait a few decades before I outfit my house with this tech.
