The HEP ( High Efficiency Pump ) experiment is a direct use of the TEP technology presented in this web site. During this serie of videos experiments some very interesting facts will be demonstrated :


Above : The full setup of the HEP experiment


The HEP experiment uses a DC immersed pump to rise water.
The water level is accurately measured with a 1000 mL graduated test tube.


The TEP unit is a full solid state device. A switch allows to bypass the TEP circuit.

HEP Testing - Experimental results

Calibration test of the water pump : The purpose of this test is to measure the losses of the water pump equipment. The test procedure is as follow :

The losses can be easily calculated and this give an measurement efficiency of 92% (8% of losses).

HEP Blank test with a 1 ohm resistor : The purpose of this test is to conduct a blank test of the charge transfert with the water pump equipment. The TEP device is replaced by an 1 ohm resistor. The test procedure is as follow :

This test is fully in line with the charge conservation law. V(C1)=V(C2) and the total charge is <= initial charge. The final volume of water transfered ( 135 mL + 110 mL = 245 mL ) is lower than the initial volume ( 355 mL, see the calibration test step 2).

The measured efficiency of the charge transfert through an 1 ohm resistor is 69%


Above : The experimental results of the calibration and the blank tests.


Above : If the BLANK test is repeated, the efficiency never exceed 100%

The BLANK test is fully in line with the charge conservation law...

HEP REAL test with the TEP unit : The purpose of this test is to conduct a real test of the charge transfert with the water pump equipment. The TEP device is now connected instead of the 1 ohm resistor. The test procedure is as follow :

The measured efficiency of the Test RUN #1 during of the charge transfert through the TEP is up to 264%.
The measured efficiency of the Test RUN #2 during of the charge transfert through the TEP is up to 250%.

A full and detailled video of the Test RUN #2 have been recorded (see below)


Above, tests RUN# 1 with the TEP active : You may notice that 185 mL of water (step #9) is raised
while only
70 mL of water (step #7) is used to pre-charge the main capacitor C1.
In this test, a total charge of 1.85 Coulomb is created by the TEP...


Above, tests RUN# 2 with the TEP active : You may notice that 175 mL of water (step #9) is raised
while only
70 mL of water (step #7) is used to pre-charge the main capacitor C1.
In this test, a total charge of 1.41 Coulomb is created by the TEP...

In any case, the tests with the TEP unit doesn't respect the charge conservation law...


Above : The diagram above shows the total flow measured at the input Vs the total flow measured at the output,
if the HEP Real test is repeated, the efficiency exceed quickly 100%
you may notice that after the step #12, the HEP begins very efficient.

Below, you may see by yourself the full videos of the HEP TEST RUN.

In the test above, the water pump has been replaced by a 12V/20W halogen lamp, C1=C2 = 21000µF at 50V
The current flowing at the INPUT is compared to the current at the OUTPUT
with the TEP disabled (bypass mode) and with the TEP enabled (active mode).
You may observe clearly that electric charges are created ( Q=I*t ) when the TEP is actived.
