Think about it for residential wireless though. Imagine a Drop Cam that you can literally stick on the wall and forget about... wireless power coming in, wireless signal going out. How many consumers will jump on that? A baby monitor camera that you don't have to worry about a cord falling into a crib and choking the baby? A front door camera or intercom on a brick facade or arched doorway that's impossible to get a cable to?
I used to work a lot with law enforcement and covert items and the dream of a true 'James Bond' wireless device that wouldn't be limited in size or battery power was something we always wanted. The range needs to grow a little bit, but it's on the right track. The capacity doesn't really bother me all that much. Think of anything small that runs on batteries, that isn't really well suited to being AC powered... and you have a candidate for this. Starbucks I bet is the first adopter of this, until they get bought out by Google and integrated into Drop Cam
How about using this technology to send power to (or recharge) wireless door locks? Build the transmitter into the wall unit and 'beam' power to a wireless lock set? How would you like to never have to change batteries, especially on high activity lock sets? Think that Schlade would benefit from that?
to have done the bare minimum to get an approval on a essentially pointless and impractical device that doesn't actually charge at a noticeable rate, but that turns the charge light on, and as it's such a technically complex issue very few people understand what it means, see "FCC Approval", and that's it.
Fails to charge a phone with a measly 100 mW at best (about 10x lower than needed)
Unsafe for humans or animals closer than 50cm
Highly inefficient, around 99% loss
I don't know enough about the space or Energous to comment but found this relevant to this discussion.
