I will refer you to basic texts on electronics and electricity.There are ways to take a charge and use it to create bigger charges.[/quote]
You cannot just take a certain wattage in and put out a bigger wattage without using up a store of power from another source, that would violate the conservation of energy. You may be able to store and build up a charge over time, but you are still confined to the amount of power going into the system.
With EM coming off an antenna (which, in 802.11, is capped at 1 Watt MAX), the energy is dispersed in several directions at once, and as it moves out to cover a larger volume of space the power at any given point in space drops off sharply.
By your logic, generators would not work because there is not enough free electrons in the air to be coaxed into the copper cables by the magnetic fields created by the generators.
What the Hell are you talking about? Electrons stay (hopefully) within the wiring while FIELDS OF ELECTROMAGNETIC FORCE go through the air. Generators do not take electrons "from the air," it's the electrons present IN THE WIRING that get moved through the circuit! This happens to work because the electrons in a metal (like coppery wire) are particularly free to move from atom to atom, hence the property of metals being generally good conductors. If electrons were actually being stripped from the air itself the oxygen would be ionized, O2 would become unstable and subsequently turn into toxic Ozone (O3) and nobody would be able to work at power plants ever.
As in, generators do not generate anything but a spinning magnetic field that coaxes electrons out of the air, it does not actually create electricity)
If you define "electricity" as a flow of electric charge like most SANE people do, then yes it does create electricity. The electrons are moved in the form of charge as the magnetic field pulls them around and pushes them through a conducting medium (air can conduct electricity, but does this so poorly that it's generally an insulator unless you overcome the resistance with very high voltages). Magnetic fields, not electrons, are what move "through the air," or at least in relation to the conductor. In a generator, the wires move relative to the magnetic field and so induce a current. In a radio antenna, the electromagnetic field of the radio waves induces a current in the antenna.
I find that one of the most misunderstood physics by anyone is electricity and magnetic fields.
"No no no, the Earth actually stands still while the Sun goes about it in a big circle! I find that this is one of the most misunderstood aspects of physic!"
