you just don’t like it cos it's going to replace Windmills.    ;)

imo its real

What - Rossi's process of turning nickel into copper and in the process release energy? Won't happen.
I sincerely recommend that you familiarize with the nuclear binding energy tables freely available, in the net, e.g. here: http://physics.tutorvista.com/modern-physics/nucleon.html. You can see that unlike the light nuclei such as hydrogen fusing to helium and thereby powering the sun, fusing anything heavier that iron (Fe) will require extra energy instead of releasing any. That is indicated by the downward slope of the curve beyond iron. Nickel is just heavier that iron and copper more so; fusing Ni to Cu won't produce any energy. But this is apparently too difficult for the greedier investors to grasp and conveniently "forgotten" by Rossi & co.

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. What I was saying, is that whether you have 1 FL tube or 300,000 FL tubes all lined up under the wires it should not effect the grid anymore than 1. Lets say I had (theoretically) 10,000 mW/M^2, and this was the energy that existed all along the HV power lines in question. Adding more of less in the way of gas tubes under these power lines would utilize the energy available but would not pull more from the grid. If I am wrong, please explain.

I think IanB is right - putting lots of fluros near HV powerlines would drain some energy from the line.
Air is a good insulator, because it has low electron mobility. Means as a dielectric, it's relatively non-lossy.
But fluros, in an E field strong enough to ionize some of the gas molecules, have long mean free paths of the electrons. High electron mobility means as a dielectric medium, fluros are really lossy. The E field is doing work accelerating electrons, and that energy gets turned into heat and light (feebly.) That power is gone, not coming back.

How many fluros it would take to drain one extra Watt from a 330KV 50Hz power line at say 10meters distance, I don't know. Probably a lot. But it definitely would drain power.

What would the equivalent circuit be? A wire carrying an AC voltage in free space, with frequency low enough to allow neglecting EM wave transmitting losses and reflectances, can be represented as a capacitor - the capacitance to nearby objects, or infinity, right?

But with the fluros and their mobile electrons, the capacitor gets a (small) series resistor, representing the loss of energy from the field.

Nice, this is some really impressive CGI work :D see their webpage: http://rarenergia.com.br
I wonder which program they used. Of course, they were a bit sloppy with this image: http://rarenergia.com.br/imagem11a.JPG The lights and shadows look very wrong and the workers as photoshoped into the image.

Oh my! But... it's NOT CGI. I've just spent half an hour staring at these images, and I'm pretty good at spotting image fl... sigh yeah, seen a few shops in my time, pixels etc. . But if those are fake they are _brilliant_ and the authors could make a living doing CGI and don't need to pretend to build... what _is_ that thing?
Also, if it's CGI, where's the brilliant animation of it running? Because I really really want to see that that thing turning over. Just can't visualize it, after it got complicated.

I too like looking at free energy scams for fun and giggles. That's definitely a great one to follow. So much girder! Such complex! Very bolts!

They are going to be sooooo pissed when it does nothing.
Alternatively, I'm going to be so entertained if it does work.

One of my favorite 'free energy' amusements, are the web adverts starting "power companies hate this!" Then they have a photo of some technical device. Most of which are easily identified, but a few are quite difficult to identify.
