The aforementioned have contributed financially to the continuing triumph of 4hv.org. They are deserving of my most heartfelt thanks.

While it claims not to be a 'perpetual motion device', I can't find any circuit diagrams or satisfactory explanations of how it works, other than words to the effect that 'Nikola Tesla was working on a device that would harness the capacitative charge stored in the Earth'.
There doesn't appear to be any scientific explanation of how it is supposed to work, and the photos show wires going 'out of shot', alledgedly to 'earthing points of different potential' It also seems to be a pretty large coincidence that it runs at 50Hz (mains frequency in Europe)
While this article probably doesn't breach the rules of 'General Chat', as previously stated, it contains no circuit diagram or satisfactory explanation of how it works, so it should be consigned to the same bin as perpetual motion machines and free energy devices.
EDIT: The patent:
claims it to be a 'free energy device'.
EDIT 2: The above link doesn't work. You'll have to follow the link in the OPs thread to find the patent.

The thought is that it is pseudoscience and not appropriate for this forum. The exception would be if someone has a go at it using the finest scientific principles and in the end has something interesting to tell us.

Joffa, the idea seems to be based on environmental power harvesting (a valid technique, like wind power) but in particular what he is proposing is using variations in local ground potential to drive it. Maybe there is some small power available from this technique, but not likely anything anywhere near worthwhile. Then he discusses something about using displacement current to drive the load at high potential with almost no conduction current, under the theory that without conduction current there would be no power lost. Which is a bit silly because displacement current is not generally lossless (dielectric loss) and the load itself will probably be driven by a conduction current anyway, i.e. with wires with current flowing through them.
And of course right now his device operates with an external power input, like so many "free" energy devices. The output power is measured by measuring light output from halogen lamps. Although a bit dodgy I suppose that could provide accurate results if it's very carefully controlled, though the outdoor setting does not give me confidence that the environment is well-controlled.
Right now JL Naudin is claiming 96% efficiency, I won't hold my breath on him breaking 100%...

What always worries me with this sort of stuff is the use of poor power measurement - non-calibrated equipment that is not true-RMS and which doesn't allow for PF.
I'm not a scientist (any more) but I would have used a calorimeter or similar absolute method of measuring output power and traceable-calibrated agreed input power monitor.
