Nothing in this article addresses the skepticism in http://www.eevblog.com/forum/projects/the-ubeam-faq/ http://www.eevblog.com/forum/projects/the-ubeam-faq/. Read that document and you will see. The "uBeam FAQ" document admits that it is technically possible under very limited conditions but mostly uses physics to claim that it will have tons of other issues such as massive power use, short range, potential safety issues, huge cost and other bad things. Basically that even if you did make it, it would be quite inferior to any other charging technology such as, say, wall outlets.
