Practical Guige to Free Energy Devices

We can see it's exactly the same as Nick Giannopoulos' setup, except that Tesla is using a generator in this
diagram, I believe for simplicity. As long as the generator is generating the exact frequency of current, it will work
fine. The secondary at the energising side is a quarter-wave coil, and at the pick-up side is another quarter-wave
coil. The highest voltage is at the far end of these two secondary coils and their connecting wire, and zero voltage
is at the very outside turn of each of the coils. Now if we change the spiral form coil to helical, it becomes Nick's
set-up. And let's take this further, we can shorten the connecting wire until the two solenoid secondary coils
actually become one big coil, then, when combined it is a half-wave coil, and the highest voltage is at the middle
point of it. Now it becomes Don Smith’s and Tariel Kapanadze’s device, like this:
Because the energy is also coming back from the energising side, Kapanadze adds another pick-up coil right
underneath the primary energising coil. This arrangement, I think, is very hard to replicate, because it is so very
hard to tune, for several reasons:
1. The Secondary wire length is rather short, and the wave speed is very very close to (π/2) x C, so the frequency
should be very high, at least 5-7MHz I would guess, or perhaps even higher.
2. The pick-up coil and the energising primary coil is too close to the centre point of the half wave secondary coil.
Because the centre point is the point of highest voltage, if the input is a little high, there would be arc shock
between the secondary to the energising coil and the pick-up coil, at lightning voltage levels, and so even the
best isolation is useless. Also, the centre point is very very sensitive, any conductor close to it will add to the
total capacitance of the coil and of course that will alter the half-wave resonant frequency. This adds more
difficulty to the tuning adjustment. Besides, after all, people don't even know it's a half-wave coil if he doesn't
tell us.
3. The coupling coefficient K is a little high, this will increase the hot transformer effect by inductive coupling, and
that will not help at all.
Don Smith did indeed say something useful. He said that we can make the secondary coil a fixed size, and then
slide the primary coil inside it. Well based on experimental results, this sliding process is altering the actual
effective length of the secondary coil. In general, we should assess coil size by counting the turns from the turn
right underneath the primary energising coil, to the turn right underneath the pick-up coil, this section is the actual
secondary, and this section should be a half-wave resonate coil, the rest of the coil just sits there doing nothing.
But it's not that simple, the terminals of the secondary coil should connect to the earth or to a large sphere, or a
typical Tesla Coil secondary with the same quarter-wave resonant frequency. Otherwise the signal will bounce
backwards and forwards in the coil producing a mess, or generating an arc, and this is bad for performance, and
this is why a solid ground connection is desirable. And this is the true meaning when Don says "slide the primary
coil to do the fine tuning".
So, returning to the Kapanadze device, the energising coil covers a large area of the secondary coil, making the
effective length of the secondary coil very much shorter, again, boosting the working frequency of the device even
higher. For such a device, it is impossible to tune it without a 20Mhz signal generator, an oscilloscope and
complete understanding of how a longitudinal wave behaves. For a start, I don't even know where to connect the
oscilloscope probe or which terminal should connect to the ground, I'm so lucky to be able to watch Eric Dollard's
