Just as an argument on the air-conditioner side of things-- this device can't generate energy unless there's a temperature difference between the wearer's body temp and the outside temp. If you were in an environment where it's hot enough for an air conditioner to be worthwhile, chances are the temp difference between yourself and the outside world won't be enough to make any sort of air conditioner run. If the outside temperature is equal to your body temperature, the device is incapable of generating power. If the temperature outside is greater than that of your body, you have to be able to *absorb* more heat into your body in order to generate the power to run an air conditioner, which would make you pretty damn hot.
