Tesla, the famed genius who 100 years ago was scamming rubes with the same impossble promises wattup is peddling? Kinda seems like time has told on that one.
Listen, Wattup isn't doing anything new. RF to DC has been around since... well, Tesla. We already use it in the insanely few applications where it's viable tech. You might even have a few RF to DC devices bolted to your house, solar panels. The problem is that Wattup doesnt have a literal star powering their chips. What was the last device you saw that was fully solar powered (calculator) - how much of the surface area was given over to that component? And how big are wattup's chips? yeah.
The power transfer Wattup promises is admittedly an impressive improvement in power while still staying within FCC guidelines, but go up one class of transmitter and youre back to playing with tech thats been around for a hundred years. We already use COTS parts for this for indoor mapping, thats what RFID inventory tags are. Or power over NFC devices. It's useful tech, but wattup hasn't shown ANY devices that actually hit their pie-in-the-sky performance goals ("recon drones"). One hour with a radio physics textbook and you too can do the math to understand why its never, ever going to happen. it's not a problem that can be innovated around, it's fundemental universal laws here.

And admit themselves that they cannot do what they claim to do safely. Including things like form factor...
