Hi SkyWatcher,

Okay on your  "sticking to the more copper mass primary is of benefit story",  that is fine with me. 
What comes from my previous post to you on the primary coil having about 0.69 Ohm resistance (as per my calculation) is that to reduce the loss in this coil, the solution invariably involves increasing the copper mass by using thicker wire for it.   

Using thicker than AWG 24 wire or using several wires in parallel as you have done so recently in the René charger tests invariably involves using more mass:  the goal is to reduce DC resistance to as a low value as possible and practical, well below 0.69 Ohm.
This tendency is to be observed for the resonant secondary coil too but obviously the mechanical size limitations bring trade-offs in the quest.

Hi Lidmotor,

you wrote
PS -- I will work on it when I figure out how to do it. Ha

Well, by now you cannot do it because the 12 hour long time period available for editing is over for your post with the high resolution picture but here is how to do it, others may also benefit from it.
There is the Modify icon at the upper right corner of your post (you need to log in and also you should be within the 12 hour editing time limit).

You can see these under your post to be modified and just click on the Clear attachment icon to remove the high res picture. Then use a picture editor (like Paint in the Windows) to reduce the number of pixels (Paint has a Resize feature).  When your picture has the not higher than 900 pixel number horizontally, then save it and attach it again to your post (as the first attachment).   It is unfortunate that the software for this forum has such shortcomings like oversized pictures cause.

TK - with enough smog, that circuit will run inductive loads too...it's the same on the right as the way motors can be driven. Works better than an FWBR with a cap.
One example of a use for everyone in the USA would be 60Hz...your Rigol scope will likely show mains noise whenever no other circuit is running and I think it would be neat to have a situation where that doesn't happen. The smog harvester removing it.
I've no idea how to do the mathematics on that, but the coil would have to be of a high turns number to bring it to that resonance point.
It may work for the UK and other 50Hz countries, as is, don't know yet.
I'd really like to build such a thing.
That would be something to behold, no visible input power but a Cree board is sat there lit up.

   Lidmotor:   Just use paint to resize the image to less than 1500 wide.  That's what I do on Windows 10,  without needing any other photo software.
   I also took apart one of those 40w equivalent, 4w led filament bulbs. But, mine has no led chips, but uses 4 led filaments inside the sealed glass bulb. The bulb itself is longer than the one you have.  And this bulb also works great, running capacitively off of my Kacher circuit, after I gutted it. I'll do a video of it soon. Just need to get the diodes on it, when I have a chance.
  The image below is taken when using a 5w solar panel connected as the input to my Kacher circuit. 12v panel, max 5 watt output.
It gives a LOT OF LIGHT.  Bang for the buck... 

   I'm expecting a 12v to 35v buck converter, so we'll see what that does to the input voltages that can be tried.

Hi Nick,

Unfortunately the less than 1500 wide is not good yet, I tested it and found the 900 pixel as the maximum.
Your above picture has 1000 and it is already wide a little...
