What are limitations of wireless transmission of electrical Power in distribution network?

The big problem with open broadcast of power is that you will send the energy to 99 undesirable destinations in attempt to send it to just 1 desirable destination. When I listen to the radio, the station's transmitter operates at kilowatts of power, and my radio receiver's antenna barely picks up milliwatts of signal power.

With broadcast radio, this isn't too much of a problem, because my radio receiver has small amplifiers that will internally boost the signal. Energy isn't the purpose of the signal, the purpose is information. Energy can always be added as needed from me plugging it in to the household circuitry. Plus, with advertisement money spent on delivering the sponsors' messages to thousands of people, the price of a continuous 50 kilowatts is a reasonable business expense. All the radio signal that doesn't make it to receivers...no big deal. Eventually it blends in to the background cosmic radio to which we are already exposed.

If you try to do the same thing in attempt to get kilowatts to me, this is both inefficient and dangerous. It is inefficient, because to operate the source, you will need to purchase a lot more energy. It is dangerous, because energy itself is both the capacity to do work, and the capacity to do damage (as I demonstrated in my bike accident today). All of those 99 undesirable locations will receive their energy in what we consider to be damage, rather than work.

If you want an easy to understand visual, imagine that when you fill your gas tank, rather than guiding the gasoline by the hose and the nozzle, the design is that it just sprays gas in a spherically symmetric spray. 99% of the gasoline spills on the ground and is a fire hazard, only to get 1% of the gasoline in to your tank. Do you really want to pay for 99 times as much gasoline as you intended to use to fuel your tank?

Having given you that visual, aren't you glad that gasoline stations built hoses and nozzles to deliver the gasoline to you?

Similarly, aren't you glad that your utility company built a network of wires to deliver power to you?
