--- Quote from: SeanB on January 24, 2014, 07:25:03 pm ---The energy is stored in the capacitance of the line to ground. The energy is returned to the system. Adding the lights will add to the voltage drop along the line and will show up in the power factor of the line. There have been some prosecutions for this under the "Theft of electricity" laws in most countries.

Would this theft be the result of induction or physical access into the grid? I understand that their is a return through the ground, but I did'n't think it would be all that noticeable on with the grid monitoring systems unless it was considerable.

As far as the radio waves , my ham radio SWAG - scientific wild ass guess .
Once the radio wave is transmitted , it exists in space / atmosphere , the makeup of the atmosphere at the moment of transmission is called propagation or is the resistive load that the power at the transmitter is trying overcome .
The power applied is determined by the desired performance of the operator .
In ham radio there are 2 extremes QRP - 5 watts or less and then max allowed depending on mode , band and rules of the origination of signal .
In QRP using mode CW - morse code , and good propagation and the correct band , ham radio goes around the world and is not so strong that it is going to interfere much .
With broadcast , they are on a set frequency within a set band - AM , FM etc. and there intent is to reach a large number so they are allowed huge power .
Receiving has no affect on transmission at all .

Kickstarter anyone?

Funny that, I actually heard a friend of a friend considering that as a viable basis for perpetual motion machine design after "discovering" the very same thing while reading his aircon unit's user manual. Only he wasn't joking...  :palm:

What I am saying is that HV power lines are emitting a fairly high level of EMF which is enough to excite the atoms in a gas tube. This energy is there all the time and is part of the loss from transmission lines.

There is a certain loss from power lines due to various factors, but if you make the power line do work by lighting up a bulb the loss will be increased.

The power line forms a capacitor to the ground with air being the dielectric material. As you know a perfect capacitor in an AC circuit consumes no power. It is only when the capacitor is imperfect (when it has a resistive component, an equivalent series resistance, ESR) that it then has power losses.

Placing a fluorescent tube in the electric field minutely increases the ESR of the line-to-ground capacitor and therefore minutely increases the power losses.

Note here we are not considering electromagnetic radiation, we are considering an alternating electric field between the "plates" of a capacitor. A power line does not "emit" a field, it creates a field. It would "emit" radiation, or EMR, but at such a low frequency the emission of radiation is of extraordinarily low power. Not enough to light a bulb.

In the US, HVAC equipment is rated in BTU/hr or tons, so as not to confuse the average consumer.
