Re: Yeah there is no way an EM source could be tapped for energy
I am interested what then in your opinion is more of a problem to EM energy transfer than the inverse square law, please quote percentage losses involved because distance is "THE" limiting factor of EM transfer.
As to the inverse square law I didn't bother to look up, I just remember the equation hence "from memory".
This discussion is about solar power which is in case you were unaware IS a form of EM energy transfer, one which is quite profitable mostly because we do not have to pay for the sun to provide the energy in the first place.
So since you are so knowledgeable what are typical comms flux densities and power from adjacent to 1 mile from source, baring in mind some people live next door to all sorts of transmitters
