Pulling energy from the ambient energy field using a coil capacitor

[Belfior]

To confirm the above statement from Jack (Ten meters of 0.5mm wire around 5cm tube using 50% turn offset had resonant frequency at 10.3 MHz in one test system.),

i made 2 different coils on a 5cm diameter PVC former using 0.5mm (AWG 24) magnet wire.

One coil is closely wound (no interwinding space), and the other has a 50% offset, meaning 0.5mm between each winding.

Carefull measurment of these coils shows via severall ways that the closely wound coil (3cm long) has a resonance frequency of 3.13Mhz, while
the 50% offset wound coil (6cm long) has an Fres of 3.9Mhz, so not even half of the above mentioned 10.3Mhz.

This shows to me that it will be very difficult to take steady measurments as slight changes will influence the results.

Anyway, here a short video about these 2 coils setup and the measurement:

The screenshot shows the response of the both coils to a pulse (purple)
Yellow is the closely wound coil,
blue is the 50% offset coil.

What Jack means by 50% offset is when one of the coilcap wires is cut from the middle and the ends are joined together. So one end from the middle is left hanging open and the other end from the middle goes to the load. The 2 coilcap wires should always be wound close together.

I think Jack was talking about my setup with the 10MHz. Have to check my measurements again on this weekend after my move is done.

Thanks Belfior,

so that would be the lower coil system in the Fig. 3;   that makes sense.

Its not the system that Jack has asked me to build yet, but i can set it up and do the measurement.

The above mentioned Fig. 3 lower coil system has indeed a higher resonance frequency of 8.93Mhz, see screenshot.
But it is very susceptible for noise like the 50Hz mains due to its open ends.
It makes the signal kind of floating.

I use a very loosly coupled FG and the load is only my scope probe.

I used a FG too and all effects disappeared when I added the diodes to the coilcap like Jack describes in his document.

I will resume testing when I unpack my lab. I will redo the tests with a similar system using a spark gap

Thanks B,

that is one of my questions to Jack, as after having finished the coil system he describes in my post #176:
http://overunity.com/17119/pulling-energy-from-the-ambient-energy-field-using-a-coil-capacitor/msg514961/#msg514961

he states to use the 'Signal generator testing guidelines' section in his PDF to do some testing with it,
but that section starts with pointing to a different kind of coil system setup with diodes and / or sparkgaps
(Fig. 6 or Fig. 7).

So not sure if i have to setup that coil system first before experiment with pulse lengths etc. and where to input the FG pulses.
