Free energy is a bit misleading, to me things like TEG and solar are what I would describe as free energy or hydro. All of those are proven and work, the one where people think you can get more out than put in is also called free energy, its important to make sure people know exactly what your talking about, that site you linked too has a couple of valid things on it like Thermal electric generation. That to me is free energy, but the perpetual motion and something for nothing type stuff is obviously stupid. The site would be good but even to me contains some serious misunderstanding about atoms etc.
I normally get this wrong when I try and explain, but if you think about energy cannot be made or destroyed just have its formed changed, then its obvious that you cant make something from nothing. YES I know I have messed the last bit up, but I understand what I mean better than I am able to describe it.
I am really interested in energy harvesting, everything from solar heating systems to hydro electric. I like HHO but from a different side, I like hydrogen cells and the idea of on board hydrogen generation. But I am also aware that as a system it isnt efficient and the production of hydrogen in terms of energy required is expensive.
I also like Rodin coils and starship coils, not because of the " special powers" they have (because thats nonsense), but they do have a couple of properties I have found useful. With starship coils the only truth about them is the very tight lines of magnetism they provide, for me this has been handy. But they do not as claimed provide more magnetism than a normal coil, And without a doubt on a project where the coil can be seen they look rather cool!
Dad is working on something that in part uses solar panels, he has some that are new and very flexible and light weight. They are slightly more efficient than normal panels but this is purely because of advances in materials.
So I guess my question is rc3po what exactly are you calling free energy? do you see it in terms like I do, or are you a more out than you put in type of person? Only asking because the first type I like talking about, the second type is a waste of good thinking time
