This page contains all the publicly available comments in English made by Russian professor Alexander Parkhomov about his experiment published on December 25, 2014 in which he attempted to replicate Andrea Rossi's Hot Cat. Parkhomov reported that he was able to generate excess heat after heating the reactor containing nickel powder combined with lithium aluminum hydride.

A collaborative project for creating a replication guide using Parkhomov's methods has been initiated. See Parkhomov Replication Procedure Guide (Framework) for details.

Additional Comments and Replies to Questions

Regarding the nickel powder and heating element:

  • "As for fuel, there are no secrets isn't present.  Simply powder mix from pure nickel and 10% of Li [AlH4]. The heater is made of a heat-resistant alloy 'nichrom'" [1]

Regarding calibration:

  • "Measurements with the electro heater which isn’t containing fuel at the power up to 1000 W were taken. The quantity of the consumed electric power after boiling of water and the amount of heat necessary for heating and evaporation added for preservation of initial level, coincided within 10%."[2]

An analysis of the nickel powder:

  • "In the appendix outcomes of sizes analysis of the used nickel powder. My next problem - to achieve long duration steady activity of the reactor. In the component of iron I do not see yet necessity." [3]

Regarding power source:

  • "Standard 50Hz AC [presumably variable voltage] with no other frequency stimulation/wave chopping was used" [4]

Q & A with the Martin Fleischmann Memorial Project:

  • We asked him if he thought it was important to have a magnetic field or if he felt it was only dependent on pressure and temperature. His response is positive for our SiC elements. A: "I believe there is no need for a magnetic field"
  • Q: How did you measure the amount of water vaporised in your control and active runs? A:"During experiment after boiling of water the invariable top level by gradual addition of fresh water was supported it. The mass of the evaporated water was considered to the equal mass of the added water. In numerous check experiments with electro heaters distinction between the consumed electric power and the energy spent for water evaporation is less than 10% (if to consider warmth of water evaporation 2,26 MJ/kg). It testifies that this technique allows to define COP about 2 and more with sufficient reliability."
  • "Q: Could the pressure drop at [above] 570ºC have resulted from absorption by nickel? A similar effect was said to be observed by Russian researchers. A: "After heating of nickel to 740ºC (8 bars starting pressure of hydrogen) the reactor was cooled to 240ºC (pressure fell to 2 bars), self-heating began, temperature rose to 360ºC and pressure fell to 0." (Note: Dr. Parkhomov must have been referring to another test here, since no pressure sensors were used in the December test)
  • Q: Could the strong fluctuations be the result of processes in the reactor? A: I observed strong fluctuations of temperature affecting the variable power supply too.
  • "At a temperature of more than 1000ºC, even with constant electric input power supplied to the heater, quite strong fluctuations of temperature of the order of 100ºC were observed."
  • Q:"Did you use Type-A (80% Ni, 20% Cr) nichrome wire or Type-C (60% Ni, 16% Cr, 24% iron) nichrome wire for the heater coil?" A: "I believe that I used type C nichrome wire in the form of a tape."
  • Q: "What gauge wire did you use for the heater coil?" A: "I coiled the wire directly on the corundum tube with intervals of between rounds of 0.5 mm, and then covered it with heat-resistant cement." [5]

A critical review of the experiment was published by Michael McKubre on Infinite Energy Magazine. [6]

Subsequent Experiments

An updated report was presented by Parkhomov at VNIIAES, the All-Russian Research Institute for Nuclear Power Plant Operation, Moscow, which shows clear excess energy from his (now improved) Ni-H reactors. [7]

He also released a 2 hour duration video describing his experiments in detail. [8]

Updated Report (January 2015)

An update to Parkhomov's original paper was published on January 31, 2015 which included data about additional experiments that had been done since the December test. [9] The image below provides a chart from an experiment carried out on January 18, 2015. When the temperature was at its highest levels, the system was measured to produce 1.72 times the amount of energy as was input.


This experiment ended when the heating wire burned out when Parkhomov was attempting to increase the reactor's temperature.

Martin Fleischmann Memorial Project Visit to Moscow

On February 25, 2015 Bob Greenyer of the Martin Fleischmann Memorial Project visited Parkhomov in Moscow, Russia, and was invited to inspect an experiment that Parkhomov was carrying out in his home laboratory. The experiment ended with the cracking of the reactor, but data from the report indicated that there could have been an anomalous heating event that took place before the reactor failed. Bob Greenyer published a document reporting in detail about the experiment with numerous photos and data representations. [10]

Journal Article

Parkhomov has written an article titled "Investigation of the heat generator similar to Rossi reactor" that was published in the International Journal of Unconventional Science in which he reports on two experiments he carried out with his reactors (performed on December 12, 2014, and January 18, 2015). [11]

Experiment Starting March 16, 2015

On March 18, the Martin Fleischmann Memorial Project reported that Parkhomov had informed them about a new experiment:

Dr. Parkhomov has managed to get a reactor running for the first time long term (more than 90 minutes of excess heat) and has attached a manometer. As of 09:53 CET 18 March 2015, it was still running.
He reports similar pressure profile to the first MFMP fuelled []=Project Dog Bone=[] test ( although lower peak ) where we saw a rise and then the pressure going below atmospheric.[12]

Subsequent reports state that Parkhomov's reactor ran for four days (March 16-20) with a COP of around 3.2, before the heater element burned out. After the heater element was replaced, on March 21st the reactor was placed back inside the heater (a separate tube containing the coiled heater element wire) and was able to continue running after starting from cold.[13]

Presentation on March 26, People's Friendship University, Moscow

Parkhomov presented a report of this experiment at a seminar on March 26, People's Friendship University, Moscow. The report and discussion on it can be found here.

Poster presentation at ICCF-19

Parkhomov presented his research in ICCF-19 held in Padua, Italy during 13-17 April 2015 [14]. His paper summarizing main experiments till that date can be found here.

He also published the fuel and ash analysis for his 3 day test conducted in March 2015, which can be found here.

Publication in the International Journal of Unconventional Science

A paper about this experiment, titled Investigation of new version of the device similar to high-temperature Rossi heat generator., was published in the International Journal of Unconventional Science [15] in June 2015. The English version of this paper can be found here.
