Hi all. Just a note on the DC2DC converter.
It was someone on this thread who told Romero to get the DC converter!!!
He didn't have it in his earlier tests...it was suggested to him by us!

I wish the latest events didn't happen.....but I think I will make a rep as well.
Another thing to note is that there is no real need for any driving coils. Any prime mover would do because the output is regulated, so i think builders should make the rotor/stators and  gen coils first and make some running tests. It will save lots of time.
All we need to do is tune the machine so that we get output under load without acting on the prime mover.
The tinkering will be in setting the coil spacing and the biasing magnets....a little sigh when thinking about that. 
Cheers.
Scotty.

I wonder why Sterling Allen wasn't all over this one? Does anyone else find that weird?

Maybe Sterling Allen could see something we don't.

Its a clear as day the  battery lead is the coax supply from the DC inverter.  If you ever stripped back a laptop supply you see the same wire. Its SHIELDED coax because its a switching inverter and is RF noisy and there are inline chokes fitted near the inverter also.

Oh wait that might be an AA battery with some black tape around it...oh bugger.

PS make sure you find some nice cores otherwise this ain't going to work. Its the very reason Muller went in search of special black Amorphous sand. However in recent years high power Switching PSU's require very high permeability cores some are 100 or 1000 times better than standard ferrite so no need to go looking for black sand.

I was able to get amorphous metals,
And can be the size of the data produced by my heart
But I can not determine: the effect of amorphous metal is indeed beyond the ferrite.

@ Tudi,
that was an very fine analysis of the problems ... and give to think about this.. tks

@scotty.
This DC/DC Converter to use is fully NONSENSE and to complicated, also with minimus 10 % losts.

It give more and EASIER WAYs, to regulate the input and putput voltages, drive up and to hold the optimum of rotating speed.

Possibly: No inverters . no semiconductors needs

There is problem with getting cores, in Europe.
Those average Joe's ferrite rods that everyone offers are crap, they are not meant for high flux operation.
I'm not into combo-core from toroids also because hole in the middle would offer "parasitic" flux path.
I guess best option is try to localize I parts from EI or other core types that are made from proper material, for example Sendust.
If anyone has had success with getting proper stuff in Europe please tell.

Possible shapes in order of preference:
rod (at least 10mm diam, 20mm length)
block
plate (can be stacked to form a block)

Materials in order of preference:
- Sendust or other high saturation point,
low eddy loss material
- ferrite meant for power applications,
with low eddy loss

And again, tinkering with steel bolts and laminations is *pointless*. Seems it cannot be said enough times

Request for admins to really try to cut the crap on this thread.
Also everyone, please learn to reply without including whole original post...
We have extremely poor Signal To Noise ratio here
