QuoteI think, that JT needs DC-Voltage. But the earth current is AC

The telluric currents are pulsed dc. The jt needs steady dc.
As it was mentioned a while back, a full bridge rectifier should be used to measure the output of the coil.

The calculations for the number of turns in the picture above are for #18 wire. A larger sized wire will reduce the amount of turns. I cant tell if the coil on the left has wire or not on it. Even so it looks like a large core.

One of the reasons I have waited,other than monetary, to build an NS coil is the statement by NS granddaughter on the use of pitchblende. NS did this in different locations and it worked though. If he didn't prepare the ground thats a plus. Another factor to consider is Radon which is radioactive also. Radon is a decay product of uranium, which is relatively common in the Earth's crust, but generally concentrated in ore-bearing rocks scattered around the world. Soils containing granite or shale have a higher concentration of uranium. NS lived in such an area.
Now Im wondering if it could be wired up like a Scalar coil.

Planning to build a Stubblefield coil, I came up with the core depicted in the attached drawing.

The idea is to use a 0,9 mm galvanised iron wire for winding the primary and for constructing the core.

Most people read from the Stubblefield patent that the iron core should also be insulated by a layer of cotton, the same cotton used to separate the many winding-layers of the primary. This gave me the idea to use a cotton string to hold the many rods of the core together (a fastening means and an insulation).

Hi great work again , i was wondering if you used one pair to turn the motor rotor , and the other one seem to act like a secondary on a transformer.

Could you put a bridge and charge a cap from that loose coil , will it stop the motor?

I was wondering if you tried it ?

I made a reed switch activated motor today.
I thought you would all like to see it in action.
It was very easy to build .
the kit came from

Jeanna:

Excellent video!

I really like the use of PVC in your device.  Now you have a reed switch running, so, there is no stopping you.
