Cool, does that mean I can get infinite power out of it as long as I can get the receiver and transmitter arbitrarily close to each other? Sounds like each time I cut the distance in half I get twice the power. Zeno saves the day!
If distance=0 represents a theoretical "full power", then how do you double that distance to get the half (or quarter) power according to the inverse law? If some distance > 0 represents "full power", then getting the TX and RX that close ought to be free of this nasty inverse square business.
