The Cold Fusion Reactor ( CFR v1.1 ) is fully based on the work of the researchers Tadahiko MIZUNO and Tadayoshi OHMORI from the Hokkaido University in Japan.

1 - Cold Fusion Reactor v1.1 - Description :

The Cold Fusion Reactor v1.1 is composed of a 700 mL glass vessel filled with a 600 mL solution of Potassium Carbonate ( K2CO3 ) 0.2 molar ( 0.2 M ).

The Cathode used is a tungsten ( W ) plate 6 mm wide, 25 mm length and 0.5 mm thick. The Anode used is composed of stainless steel  mesh 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 v1.1 is powered with a DC voltage through a bridge rectifier connected to an isolation transformer. The voltage input has been measured with a digital oscilloscope Fluke 123 with a Shielded Test Lead STL 120 ( 1:1, 1 Mohms/225 pF ). The current input has been measured with a current clamp CIE Model CA-60A ( Accuracy DC Amps ±1.5%, AC Amps±2% (40Hz-2kHz), AC Amps±4%(2kHz-10kHz), AC Amps±6%(10kHz-20kHz) ). 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% ). ( see the photo above ).

3 - Tests results :

Test procedure :

1) The temperature of the K2CO3 solution in the CFR has been set initially to 90°C.
2) The weight of the CFR v1.1 has been measured initially, it was 882 g.
3) The power supply has been switched on continuously and the Voltage/Current datas has been recorded in the Fluke 123 digital oscilloscope used as a data logger, up to a temperature of 96°C.
4) Then the weight of the CFR v1.1 has been measured, it was 868 g.

The run time has been 69.2 seconds.


The Voltage/Current datas logged give an average electrical power input of 359.5 Watts during 69.2 seconds, so this gives :


The evaporated water in the CFR during the full boiling was 14 mL. We know that we need 2260 J/g to vaporize water. The temperature rise of the 600 mL was 6°C. So, this gives :

ENERGY OUTPUT = ( 14 x 2260 ) + ( 600 x 6 x 4.18 ) = 46688 Joules

Power OUTPUT = 674 Watts, Power Gain = 314 Watts

Energy OUTPUT/INPUT = 46688 / 24877 = 1.87

Notes from Jean-Louis Naudin : This new test of the CFR v1.1 with the Potassium Carbonate ( K2CO3 ) gives better results than with the Sodium Hydrogenocarbonate ( NaHCO3 ). The heat produced around the cathode is very strong and need 4.4 less of power than with the NaHCO3. In the energy output calculations, I have used only the energy of the heat generated by the plasma. The energy of the burning Hydrogen-Oxygen mixture has not been taken into account...

In a next test, I shall used a bigger Tungsten ( W ) cathode electrode for a longer test run...
