Mythbusters had an outtake on this "waste energy" concept.

It's partially true, they got electricity out of it, but only 8 millivolts and that was with using an incredibly large spool of wire hoisted into close range of the lines.

It can't be enough to power a fluorescent tube, especially without a ballast regulating the flow of electricity through the tube.

Maybe I'm wrong, but I'm calling shenanigans on this one. :down:

According to an electrical engineer that I work with that could be a real photograph. The potential is there but the current traveling through the air is very low. The tubes will only light up very dimly, but with a long exposure they can appear bright.

Come to think of it, I remember having something like this happen at home. I took apart a fluorescent lantern and was able to get it to light with only one wire connected. The air completed the ground path.

Darn, so much for going out under some high tension lines and having a lightsabre duel.

Yah the picture looks like an over exposure with extremely long shutter speeds, probably only way to capture a lightning bolt anyways....

Perhaps that's what it is, I just didn't see how those lights could be burning that brightly without some kind of external help.
