The uBeam FAQ
EEVblog:
So, turns out Meredith's new invention is a collapsible bike helmet. Seriously, that's what it is.
Not a new idea of course, this Indiegogo just raised $3.5M for one:

But Perry's one is the size of a banana. Just like Theranos could test 800 things with drop of blood...
StillTrying:
A bike safety helmet that collapses on impact, what could possibly go wrong. >:D
JimRemington:
With the new focus on "intellectual property" uBeam now looks like a Solution In Search of a Problem.

Lets say they use around 25W to deliver the 3W of electrical power, the limit for class 1M is around 150 mW for "eye safe" lasers I think. So they have to detect 0.6% beam occlusion to stay safe, seems hard.
