Wireless power distribution is a load of bollocks! Pardon my directness, however it is not realistic.
Nikola Tesla was determined to do this along with General electric as his main sponsor. He proposed a network of towers emitting power for people to use, the major downfall was that there was no way to bill people. So GE pulled the plug. The other issues are to do with interference from such a high voltage electric field, it caused all sorts of problems where it was trialed, so it's not a realistic option.
High voltage transmission lines, and radio towers, do emit energy, it is spherical and goes out in three dimensions, so for a larger radio tower, of for example, 100 kW transmitter, for each meter you are away from it, the amount of power that you can possibly receive is calculated by the inverse square relationship. At 100 m away, the amount of energy is 100 kW/(4·pi·r2), where r = 100 m. This equates to 79.58 W/m2. So if your antenna dish is one square meter in area, and you stand at 100 m from the 100 kW transmitter, at best, you have enough power to run a incandescent light bulb. not much really. move away another 100 m, and you are down to 40 W. This is a large antenna, and for not a great return, and you will most definitely be questioned. I doubt, however, it would really have an effect on people receiving a signal, you will only create a tiny blind spot in the transmitters path.
On the other hand high voltage transmission lines conduct most of their energy, to there is far less radiated out. Similar maths can be performed to work out the radiated energy and potential recieved energy. In doing this, you are not "stealing" energy, just collecting waste, and recycling it, so it should not pose a problem to anyone, it may raise some eyebrows with your neighbors, depending on where you live.
All of these forms are far field radiation, near field radiation does work for transmission of energy quite effectively, but in this situation, you are transmitting and receiving, so it is not free!!!
There are of course, RFID devices, which do not consume much energy, so do work quite well using far field radiation, but not much energy is available, just enough to power some small microprocessors.
