Enough power?
Doesn't seem like there would be enough power in a WiFi signal to power much of anything. True, a small device might not need much power, and its easy to imagine a super low power chip running the show. But wouldn't a reciever alone require more power than is present in a WiFi signal? I am not an electrical engineer, but this just doesn't seem right.

Peets vs. Starbucks: Who's got the best backscatter collection?
The future competition between chi chi coffee ships may depend, not on whether they offer WiFi but whether they offer wireless backscatter. It may prove to be the service that pulls in customers, not the cappucinos or lattes. The opportunity for battery-less devices to function via use of "reflected" energy could someday even make the coffee passe. If we got over our caffein addiction, the possibiility of backscatter utilization could remain the reason for existence of periodic urban shops, populated by battery-powered and battery-less wireless device users, busily working away.

Re: batteries
Very cool technology. We all hate batteries, but must live within the confines of them for the time being.

However, technology like this will change that – or at least prolong the time that devices can last. This will be especially true for internet-enabled sensor systems.

with the battery issue out of the way...
...all that remains is to demonstrate that consumers gain meaningful value from the Internet of Things. So far, I'm not quite convinced.

batteries
I'm so glad some have decided to address this problem. It is so frustrating to have your supposedly mobile device not function because it is not tethered into a power source. And I have yet to find any that truly live up to the "estimated" battery life.
