1 - The Cold Fusion Reactor v4.0 - Description :

The purpose of this test is to conduct a 30 minutes test run on the CFR v4.0 and to calculate its efficiency with two different methods ( before and after the cool down period ). The electrical power input is measured directly on the power grid with an electronic Power-Meter.

The Cold Fusion Reactor ( CFR ) v4.0 uses a big 5000 mL Dewar vessel filled with 2000 mL of demineralized water and 55.3 g of Potassium Carbonate ( K2CO3 ), the electrolyte solution used is 0.2 molar ( 0.2 M, ). The height ( 180 mm ) of the Dewar wall above the surface of the electrolyte avoids some eventual projections of electrolyte outside the reactor.

The Cathode used is a pure tungsten rod ( W ) 3 mm diameter and 45 mm length from tungsten TIG electrodes (WP) commonly used forTIG and Plasma welding. The Anode used is composed of stainless steel grid ( 50 x 160 mm ) maintained with a stainless steel  shaft. All the wires connections are made with a 1.5 mm2 copper flexible wire gained with silicon.

2 - Experimental test setup :

The CFR v4.0 is powered with a voltage of 204 V DC through a bridge rectifier connected through a variable transformer ( Variac ) to the 220V AC power grid line. The temperature has been measured with a type "K" temp probe ( NiCrNi ) connected on a VC506 digital multimeter ( -20°C to +1200 °C with an accuracy of +/- 3% ). The electrical power input is measured with Power-Meter EKM 265 ( An Energy-Cost-Checker ) directly connected to the grid line, the measured power include the power consummed by the Variac and the CFR power supply ( see the photo above ).

Technical Data of the Power-Meter EKM 265 :

- Supply voltage............ : 230 V AC / 50 Hz
- Tolerance..................... : + 1% + 3 digit
- Max. Current.............. : 11.6 A
- Max. Wattage............ : 2650 W for specified tolerance
- Surrounding temp...... : from +10°C to +40°C
- Protection Class......... : 2

This unit has been tested according to the following EC Directives :
89/336/EWG ( EMVG dated Nov 9, 1992, Electromagnetic Compatibility )
73/23/EWG ( GSG dated June 11, 1979, Low Voltage Regulation dated Feb. 19, 1973 )

3 - Test results :

A 30 minutes test run has been conducted with the CFR 4.0. After 30 minutes of run, I have decided to switch off the power supply because the reaction was becoming too violent inside the CFR. A great amount of steam was produced, see the photo below.

Test procedure :

1 - The CFR is filled with 2000 mL of a solution of Potassium Carbonate ( K2CO3 ) at 0.2 M. ( Ambient temp : 23°C ),
2 - The K2CO3 solution is pre-heated to
T1 = 75°C, a small magnetic steerer is used.
3 - The weight of the CFR cell, with its wires deconnected is
M1 = 4245 g
4 - Then, the wires are quickly re-connected and the power supply is swiched on while the power-meter is started for recording the power electrical power input,
5 - After
30 minutes of test run, the final temperature is measured ( T2a = 100°C ), the power supply is swiched off and the recording of the power-meter is stopped then immediatly the weight of the CFR cell is measured M2a = 3805 g,
6 - After few minutes of cool down and when the temperature of the solution is equal to
T2b = T1 = 75°C, the weight of the CFR cell is measured again M2b = 3780 g,

The measured electrical power input is 347 W/hour.

Notes from Jean-Louis Naudin : It is important to notice that the measured electrical power includes the power consummed by the Variac and the CFR power supply ( efficiency ~ 60% ). The real electrical power at the CFR input is lower due to the losses in the power supply itself and thus the true efficiency of the reactor is greater...
