Many readers of this blog will know the name EEVblog, it's a website and online forum for talking about electronics run by Dave Jones, an Australian engineer. It's host to the uBeam FAQ, which puts together a lot of information on uBeam in one place. In addition to the forum, Dave makes videos where he delves into topics in a pretty entertaining manner, and for his 1000th video, he takes on uBeam.
Gotta say, he does a great job of covering the tech in an entertaining manner, not sure I could have done better myself.
An interesting point he makes is the difference between possible and practical, and it echoes a comment from one of my first posts a year ago that always seems to be missed:
"In theory, it can be done in limited cases, but in practice cost and efficiency issues will likely render it impractical."
Enjoy the show.
