Void... Normal you short circuit it.
Tinman, i respect you but dont worry about taking on your shoulder to save the money and time of everyone... Giving your opinion is really the best thing you can do! As you already know the best way we learn in life is by doing our own experiment.
I think the thing to learn here is a principe and if someone want to play with it and dont have the money to follow what  Clarence are doing he/she even can try the "principe" with low cost material like some kind of joulethief as the source and foil paper for the ground captor with the same surface contact ratio as Clarence want to achieve (4/60 or 1/15). It is up to everyone to made their own experiment at their level and to learn something... Even with bad experience, we learn!

Hi wistiti. No, greater than 920 Amps measured on the 3 turn secondary seems very high to me.
Why the current is measuring so high on the 3 turn secondary, I don't know.
I also don't know what the winding turns count is on the primary winding, for turns ratio calculation purposes.
The other question is exactly how are B&L intending the secondary on the single transformer arrangement to
actually be wound? Anyone have any idea or details on that?
All the best...

The clamp meter reads current by the strength of the magnetic field around the wire. If your clamp meter is to close to the transformer,then it may be reading the magnetic field around that transformer as well,which would be extreemly strong with your shorted 3 turn coil. Even then,1000 amps should fry that wire in no time flat. If we look at an arc welder,we can melt 2.5mm steel rods with only 60 amps,so something is amiss with your clamp meter.

Hi tinman. There is nothing wrong with the clamp-on ammeter itself. It is working fine.
Regarding the bit about the strong magnetic field around the 3 turns of wire on the secondary, that is what
I had already suggested as a possible explanation in my comments about the test I did.   It is possible that
you can't make reliable measurements with these types of meters when so close to the strong magnetic
field around the transformer windings. That might possibly be the cause of the very high current measurement.
Measurements aside, with the 3 turn secondary, the current is much too high for the 4 AWG wire. The wire would start
burning up very quickly if left energized for much longer than 5 or 10 seconds or so. The problem with info in patents is people often   
seem to obscure important details in the patents on purpose to make it very hard, if not impossible, for other people to replicate based
on the patent info alone.
All the best...

P.S.
In case anyone is not familiar with the AWG wire gauge system, 4 AWG wire is 5.19mm diameter, and 21.14mm^2 cross sectional area.
Regarding the current handling capacity of 4 AWG copper wire, one table I found lists it as follows:
Maximum amps for chassis wiring:  135 Amps
Maximum amps for power transmission:  60 Amps.
Note on these two specs:
[The Maximum Amps for Power Transmission uses the 700 circular mils per amp rule, which is very very conservative.
The Maximum Amps for Chassis Wiring is also a conservative rating, but is meant for wiring in air, and not in a bundle.]

The resistance of 4 AWG copper wire is supposed to be:
Ohms per 1000 foot:  0.2485
Ohms per km:  0.81508

Try with only 1 or 2 turns.
