If anyone has access to the full Clemente patents i would lobe to see them.


I have made a full analysis of the 1902 device commented on by Nikola Tesla.
While presented as 3 parts, the device itself is only one part.
The second part being a variable resistor
And the 3rd, and a timing circuit.
In our modern times these components can be replaced as followed:


Part 2: can be replaced by a series of 10-100 Ohm potientiometers
Part 3: can be replaced by an integrated circuit timer. (at the IC operating cost)
Please note: the "automotive-style rotary distributor" used in the original device
                   included some quantity of current draw from the battery to rotate.


I have included some crude sketches to display (what i believe is) the most efficient method.
This is to share the second coil of the first stack with the first coil of the next consecutive stack.
As shown in the 2nd drawing.
Pick-up coils (P) are connected in series, each Induction Coil has its own lead from the timer.


The 3rd image includes a timing table, the (Inc) value will be tuned for performance.
These numerical values are often measured in milliseconds on the IC
My math is decimals of whole seconds so do not forget to move the decimal.


I have included a theoretical assessment of voltage and current values of the "ideal case"
and timing increment maximums for both 50 and 60 Hz cycles.


Before you begin, I recommend creating shielding walls of multi-layered inductive sheet metal
Such as the casing metal from decommissioned microwave ovens.


While there does not appear to be an inherent danger, there are possible high-frequency emissions at certain timing configurations, resultant from signal reflection and colliding peaks.
I would expect at these nodes, to find a decrease in output performance, therefore a final version
should (theoretically) have minimal high frequency emission.


The physical configuration of my drawing is in a straight line, however circular configuration would be further beneficial.

About wire guages (before anyone asks...)


The "ideal case": the pick up wire is 2x the diameter of the induction coil wire.
Without dealing with too much technical discussion, there are 2 inductors, therefore:
General rule of thumb
Double the thickness of the pick-up
OR
double its length


(I/V)

About the variable resistance of each step in the induction circuit::
The first coil has the highest resistance, and therefore the lowest current
resistance is decreased (by ~10 Ohms in the original device) for each consecutive coil.
Therefore: a separate trim pot should be used for each induction coil.
and each tuned appropriately such that maximum output on the pick-up coils is achieved at each series junction.

I recommend beginning your research with a 12v source
And work your way up from there if you feel it necessary.

Sir Natarajan
You have already contributed the best. I think that you should listen to your people and stay away from these unhealthy magnetic fields. I wish you a quick recovery of your health and if you have time we'll be here to listen more of your experience.

ps. You know, what you have described is also what Daniel McFarland Cook was doing back then. I had built once a coil in these huge specifications but never thought to plug it in mains 220V. So i missed the effect.

As for health issues with these devices, perhaps it is freq related such as Tesla talked about.  Good eff can be had below 20khz. Higher than say 50k, then you just built a radio station and are in close proximity. I like to stay low freq.  So maybe there could be changes to make it lower freq?
There are power supplies that can run near 150khz.  not sure its necessary, other than the need for a super stable output for sensitive equipment.
