The Cold Fusion Reactor ( CFR v1.4 ) is fully based on the work of the researchers Tadahiko MIZUNO and Tadayoshi OHMORI from the Hokkaido University in Japan.

1 - Cold Fusion Reactor v1.4 - Description :

The Cold Fusion Reactor v1.4 is composed of a 700 mL glass vessel filled with a 600 mL solution of Sodium Hydrogenocarbonate ( NaHCO3 ) 0.5 molar ( 0.5 M ). The Sodium Hydrogenocarbonate ( NaHCO3 ) or baking soda is commonly named in France " Bicarbonate de Soude ".

The Cathode used is a pure tungsten rod ( Th-loaded W ) 6 mm diameter and 45 mm length from tungsten welding rods. 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.

The Cathode used comes from tungsten welding rods.

2 - Experimental test setup :

The CFR v1.4 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 NaHCO3 solution in the CFR has been set initially to 80°C.
2) The weight of the CFR v1.4 has been measured initially, it was 760 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 v1.4 has been measured, it was 734 g.

The run time has been 28.2 seconds.


The Voltage/Current datas logged give an average electrical power input of 2046.2 Watts during 28.2 seconds, so this gives :


The evaporated water in the CFR during the full boiling was 26 mL. We know that we need 2260 J/g to vaporize water. The temperature rise of the 600 mL was 16°C. So, this gives :

ENERGY OUTPUT = ( 26 x 2260 ) + ( 600 x 16 x 4.18 ) = 98888 Joules

Power OUTPUT = 3507 Watts, Power Gain = 1461 Watts

Energy OUTPUT/INPUT = 98888 / 57702 = 1.71

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...

Notes from Jean-Louis Naudin : Woow, this version 1.4 of the CFR is the best one that I have ever seen, it is really impressive and the water warms up very quickly. In spite of the high power and the high temperature, the Th-loaded W Cathode is still clean after some tests runs.
