Theoretically, would it not be possible to run a conductor in parallel with a commercial power line and make use of the EMF that is normally lost as radiation of magnetic field into space by inducing it into the parallaled conductor and attaching it to a load??

 

Hi

Yep, in theory. When you talk about power transfer, though, you need a resonant structure. Considering the wavelength of a 60 Hz wave, it gets a bit unwieldy. Plus the power company is going to notice and demand payment for any power you manage to grab. All the enchroachment on the right-of-way will be a problem, too.

Good luck, by the way - Nicola Tesla used up a lot of money trying to broadcast power, and essentially proved it was impractical.

:lol: I did a similar study in Electromagnetics where a closed circuit is created parallel the conductor and its actually quite a successful method, particularly if you can minimise the length of wire that runs orthoganal to the transmission line. I wouldn't advise you to do it, however, as it is illegal!

 

Why is it illegal? Or is it illegal if the coil is on the power company's land?

 

hi,

that's because you are deriving electric power from their power lines. simple as that and besides are you going to pay whatever you get?

Mozikluv has basically got it in one. You are generating your voltage from the magnetic field produced by the transmission line - in a strange technical sense your actually in contact with the transmission line, absorbing something directly from the transmission line. In a more common sense you are generating a voltage from power loss in the transmisson line which is paid for by someone - this is classified as theft.
