An energy harvesting project

[AlienGrey]

Hi Julesp;
Sorry to be a pain but could I please ask you a few searching questions as the device look's rather complicated
to be broken down for experimentation and i'm hoping you might be able to answer from memory.

The coils were the cores tuned to any resonant 'in tune' frequency with or with out the coil and what is the coils inductance and resonant frequency ? and what did you use for the core. Also have you a scope shot of one cycle
of rotation to view.

If its a problem please PM me.

Many thanks Sil

I was getting much better in the 5-15 range

I find that very difficult to believe. A COP of 5, you would have energy to burn and should have little problem convincing anyone with the amount of excess power available. For me, any COP over 1 is an achievement, anything close to 2 would be Nobel Prize material.

To demonstrate COP > 1, do this.
Start with two batteries, identical.
B1 is fully charged (100%SoC). B2 is partially charged (80% SoC).
Place B1 as Run battery. Place B2 as Receiving battery.
Run system until B2 is fully charged, to 100% SoC.
Switch (manually) B1 and B2.
Run until B1 is fully charged, to 100% SoC.
Switch B2 and B1.
Run until B2 is fully charged, to 100% SoC.
Switch B1 and B2.
Run until B1 is fully charged, to 100% SoC.
Repeat as long as you can.

If the needed run times decrease with each cycle, you have something interesting.
If you are soon, after a few exchanges of B1 and B2, unable to reach 100% SoC on the Receiving battery, COP < 1.

thx a lot mr JulianP sir

i will try to build this, fast as i can   
your work and your papers on the flyback generator are amazing !!
but what really inspires me is your openness and willingness to share your knowledge with the world
If I'm successful I'll handle it the same way!!

thx a lot

The if you happen to use a LA DS battery that sort of device uses approximately 50 percent of the energy to store your charge from my experience and from building various
magnetic rotor generates for every 5 units of energy put into the unit 1 unit is wasted in
reverse BEMF being wasted in heat.

I'm not saying the device doesn't work but the device would be expensive to build
and one would have to ether make or buy the PCB and that might be difficult with out
a layout or rats nest listing and copy of the Gif file ect.
but some explanation of info would be very helpful.
