   Itsu:   In his last video, he is showing how we have been missing out on 1/2 of the available juice to power the leds.   He is also showing us how the loop creates a much bigger area for the HV to work on.   Things are getting interesting...  and we're all just learning the ropes, together.
   The Doc is just guessing at what is going on, and could use some help from guys like you, with all the test gear.

    I'm still following along.  Now my wireless field has grown to about 3 or 4 inches away from the L3 coil, sometimes even to 6 inches away from the source, and even further
    I think it IS there that the magic lies

Itsu--  I agree that at this point it is difficult to know which way Doc is going with his experiments.  I found this video dealing with capacitive power transmission using just the signal from a function generator and it may apply to what we are looking at:

NickZ---  It looks like you now have things working right.  Any thoughts about it?  What do you think is happening?

Hi Itsu,

Many thanks for all the trouble you kindly invested in doing these measurements.
The close field may have influenced the probes near both ends of the L3 coil, that was probably the cause why the amplitudes changed that much, mainly after you reached the other side of L3. 

The latest video from the Doc is interesting in that it turns out it is NOT the loop current which makes the LEDs give light but the self capacity in parallel with them each, forming the individual current loops for each LED. You also measured rather low loop currents with the current probe, around between 1 to 2 mA or so, most of the time and it is a low value to cause brightness you found.

With the use of the breadboard the Doc may wish to indicate there is no need using the big diameter loop (but it needs further refinements like the use of coupling capacitors to separate the two loops galvanically from the common L3 when two chains of diodes feed the common points of two LED boards).

Thanks guys,

Lidmotor,  yes, nice video, this impedance matching is important, but its hard to find a good match without
very expensive equipment.


Gyula,  no problem, and yes its interesting that he mentions that the self capacitance in parallel with each
led forms a current loop, but no more mentioning of a time delay, and this is where i do have problems with,
this "change of plans" all the time.

Or does it all fit together in the end like a big puzzle?

Probably Dr.Stiffler wants to show the reversibility from an " optical rectenna" device  and then closing the loop.
An electro- optical or opto- electrical carnot cycle arrangement in macro- stage with later morphing MEMS possibiity.
