Forest Sir

I think you all miss the point here.

My knowledge is very low and so if I make mistakes please advise.

I think this wireless transmission of electricity is based on resonant capacitive coupling. Within the area of influence of the transmitter any device that resonates with the transmitter can be coupled to it and it would work to produce output. The area of influence of transmitter can be increased by using repeaters at proper distances.

However if resonant capacitive coupling is achieved in theory each resonantly coupled  device must produce output. This is how radio stations work.

I understand that one such emitter should be able to power 1000 devices each with an efficiency of 50 to 60% but the sum total of all would be far in Excess of energy consumption of transmitter.

The key to do this resonance coupling.

I have seen that one type of lamps are resontly coupled and light up without any wire being connected to them. but it can be explained as capacitive coupling.

Another type of lamp does not light up for it is not showing resonant capacitive coupling.

Let me test some time whether I can light up lamps that would need 1000 watts normally from the grid  would wirelessly light up with just 440 watts of input. If they do then we are one step further in to this area. But will it work or won't we need to test and see.

All of you have different perspective of how an Elephant would like and disagree with each other when no one appears to have seen an Elephant in the first place. This is the problem.

Unfortunately it only resulted in a shouting match.
No useful knowledge is being transmitted to lay people like me.

Here is the critical quote from the Wikipedia theory section:

At much higher frequencies, however, it is possible for the return circuit (which would normally be connected through a second wire) to utilize the self- and parasitic capacitance of a large conductive object, perhaps the housing of the load itself.
