But I'd like to know if the power density of this device can get anywhere close to the "health hazard" limit. We need citation or numbers about that. I'm sure you can already harvest some microwatts from wifi, and most people agree that nobody dies because of that.

Of course nobody dies of WiFi. I'm not claiming that WiFi kills you. What we are talking about here is transmitting multiple Watts (or else your phone takes forever to charge), or even more, through the air. That's a lot of orders of magnitude more than microwatts.

  And microwave ovens are orders of magnitude more than the claimed 1-4 watts, so stop using that as a scare tactic.

    Microwave ovens are isolated. They certainly don't output watts to the outside. "A Federal standard limits the amount of microwaves that can leak from an oven throughout its lifetime to 5 milliwatts (mW) of microwave radiation per square centimeter at approximately 2 inches from the oven surface." http://www.fda.gov/radiation-emittingproducts/resourcesforyouradiationemittingproducts/ucm252762.htm http://www.fda.gov/radiation-emittingproducts/resourcesforyo...

      I bet new and well-maintained ones don't, but I've seen lots of crummy old microwaves in offices that absolutely pummel the wifi when they're in use.

        What's so weird about that? Microwaves have fans to exhaust heat.

      Microwave ovens are very leaky. A coworker and I walked around our office with a spectrum analyzer* and turned on microwaves. Much leakage into the upper 2.4GHz wifi band on every one we tested, no matter old or brand new. * Actually, we were using a Wi-Spy. No need for sensitive lab equipment to detect this much radiation.
