The Aquino's System-G v1.01
Testing the device, by JL Naudin

created on March 25th, 2000 - JLN Labs - Last update April 6th, 2000




This project consists of 4 phases ( A, B, C, D ) :

The System-G Project : PHASE B

The System-G v1.01 is now under construction, ( see the picture above ). The working frequency is 50 Hz and the ELF dipole antenna is 2 x 8 m ( one branch of the dipole is red and the other is blue ) they are interweaved for reducing the inductance effect. (see below ).

In the picture above the iron powder has not yet been added, the ELF dipole antenna is placed in the iron shield.

The iron powder ( 98%, 40-160 m) used as medium for ELF waves propagation.

The System-G v1.01 during the filling process with the iron powder.

ELF Antenna weight : 966 g
Iron shield weight : 426 g
Total weight of the System-G : 7050 g

The System-G v1.01 is now ready, the next step is to do the impedance matching between the ELF antenna and the power supply.
This will be done by balun transformer connected between the power grid ( 50Hz ) and the ELF Antenna,
See the ELF Antenna design : The TEE Matching calculations

The ELF Antenna used is a true dipole, there are two quarter-wave elements. The overall length of the dipole is a half-wavelength. When power is fed to the antenna, the current and voltage vary along its length. The current is maximum (loop) at the center and nearly zero (node) at the ends of each branch of the dipole, while the opposite is true of the RF voltage. The current does not actually reach zero at the current nodes, because of the end effect; similarly, the voltage is not zero at its node because of the resistance of the antenna, which consist of both the RF resistance of the wire ( ohmic resistance ) and the radiation resistance. The radiation resistance is an "equivalent" resistance linked to the radiation properties of the dipole. The radiation resistance is the equivalent resistance that would dissipate the ELF power the antenna radiates, with a current flowing in it equal to the antenna current at a current loop ( maximum ).

You will find below my current datas about the System-G v1.01 under construction, you need only to fill the conresponding fields ( a,b,c,d..) with these datas in my System-G calculator and click the button "Calculate". So you will be able to see the "expected" results....

JLN's tests feedback ( 04-06-00 ) :

The measurements has shown that my current Antenna setup (v1.01) radiates a weak ELF power, so the measured current is low and thus the dissipated power... The reasons are :

Measurement of the resonant frequency of the ELF dipole v1.01 :

I have measured the voltage with a high impedance voltmeter ( this is also been confirmed with an oscilloscope ) between each ends of the dipole :
At the resonant frequency,
the voltage output is about 8.9 times the voltage input. The frequency was 535.3 kHz and was generated by a function generator ( Tektronix AFG310 ) set for 10V peak-peak sinewave at 50 ohms.

A normal 2x8 m dipole antenna correspond to a working frequency of 9.4 MHz in the air medium. With the iron powder used as the medium for propagating the ELF waves, the reduced length is now 17.5 times lower than in the air... This is very interesting and this confirms that the length of a dipole antenna can be significantly reduced by the surrounding medium, the iron powder in this case.

More to come, stay tuned....
