1 - The Enhanced Cold Fusion Reactor v3.0 - Description :

The Cold Fusion Reactor ( CFR ) v3.0 uses a new enhanced design with a 1000 mL Dewar vessel filled with a 600 mL of demineralized water and 41.5 g of Potassium Carbonate ( K2CO3 ), the electrolyte solution used is 0.5 molar ( 0.5 M, ). The Dewar vessel, used as the container for the CFR v3.0, keeps the strong heat and the light energy produced by the reactor. The reduced output of the Dewar neck avoid some eventual projections of the water outside the vessel.

The CFR v3.0 runs at a very stable regime and the power efficiency measured during all the tests conducted is more than 200%.

The Cathode used is a pure tungsten rod ( W ) 3 mm diameter and 25 mm length from tungsten TIG electrodes (WP) commonly used forTIG and Plasma welding. The Anode used is composed of stainless steel grid 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 v3.0 is powered with a DC voltage through a bridge rectifier connected through an adjustable isolation transformer to the 220V AC power grid line. 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 - RUN #1 - Test results :

Test procedure :

1) The temperature of the K2CO3 solution in the CFR has been set initially to 83°C.
2) The weight of the CFR has been measured initially, it was 1336 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 102°C.
4) Then the weight of the CFR has been measured, it was 1292 g.

The run time of the CFR has been 124.8 seconds.


During the test, the production of steam is very strong ( see above )

RUN #1 - POWER INPUT/OUPUT and EFFICIENCY of the CFR v3.0 :

The Voltage/Current datas logged give an average electrical power input of 574.8 Watts during 124.8 seconds, so this gives :

ELECTRICAL ENERGY INPUT = 71739 Joules

The evaporated water in the CFR during the full boiling was 44 mL. We know that we need 2260 J/g to vaporize water. The temperature rise of the 600 mL was 19°C. So, this gives :

ENERGY OUTPUT = ( 44 x 2260 ) + ( 600 x 19 x 4.18 ) = 147092 Joules

Power OUTPUT = 1178.6 Watts, Net Power Gain = 603.8 Watts

Energy OUTPUT/INPUT = 147092 / 71739 = 2.05

4 - RUN #2 - Test results :

Test procedure :

1) The temperature of the K2CO3 solution in the CFR has been set initially to 86°C.
2) The weight of the CFR has been measured initially, it was 1334 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 103°C.
4) Then the weight of the CFR has been measured, it was 1286 g.

The run time of the CFR has been 127.2 seconds.

RUN #2 - POWER INPUT/OUPUT and EFFICIENCY of the CFR v3.0 :

The Voltage/Current datas logged give an average electrical power input of 518.2 Watts during 127.2 seconds, so this gives :

ELECTRICAL ENERGY INPUT = 65918 Joules

The evaporated water in the CFR during the full boiling was 48 mL. We know that we need 2260 J/g to vaporize water. The temperature rise of the 600 mL was 17°C. So, this gives :

ENERGY OUTPUT = ( 48 x 2260 ) + ( 600 x 17 x 4.18 ) = 151116 Joules

Power OUTPUT = 1188 Watts, Net Power Gain = 669.8 Watts

Energy OUTPUT/INPUT = 151116 / 65918 = 2.29


After a lot of tests runs, some small longitudinal cracks are visible on the pure W cathode,
these small fractures are produced by the Hydrogen Embrittlement Cracking effect ( HEC ) on the tungsten.
