I thought this technology sounded familiar...I wrote about it in September: http://www.designnews.com/author.asp?section_id=1386&doc_id=267327 But I think your story takes a slightly different approach and talks about some aspects of the technology I didn't cover, so it's still relevant!
Cabe, the approach you mention is just the way RFID tags work. In the case of RFID a device, the reader, sends out a signal and, for passive RFID tags, the energy is used to power the tag and respond with the information. That is not to say that this is a great idea. As your article points out, in populated areas we are inundated with RF signals. Of course, the people who are against smart meters, for example, which often use WiFi, say that it is the meters that cause them medical problems. One of the types of energy we have in abundance in the air is WiFi signals. This research shows that there is a lot more than the meters energizing the environment around us.
A middle school team from Rochester, Mich., has again nabbed the grand prize in the annual international Future City Competition, which drew students from 37 regions of the United States, as well as from England and China.
The word “smart” is becoming the dumbest word around. It has been applied to almost every device and system in our homes. In addition to smartphones and smart meters, we now hear about smart clothing and smart shoes, smart lights, smart homes, smart buildings, and every trendy city today has its smart city project. Just because it has a computer inside and is connected to the Web, does not mean it is smart.
Are you being paid enough? Do you want a better job? According to a recent survey Manpower released just before Engineers Week, employers and engineers don't see eye-to-eye about the state of US engineers' skills and experience.
