The '''Focardi-Rossi Energy-Catalyzer''' (also ''E-Cat'' or ''Rossi Energy Amplifier'' or just ''Rossi energy catalyzer'') is an alleged compact fusion reactor based on an assumed [[Cold Fusion]] technology which is planned to be brought to market in 2011. While allegedly using no more than several hundred Watts in electrical heating energy, it is said to emit a heat output capacity of more than 10&nbsp;kW. After reaching operating temperature the electrical heating is said to be turned off. According to Italian inventors, alleged engineer(see below) Andrea Rossi<ref>Rossi: ''I am a doctor in the Philosophy of Science and Engineering from the Universita’ Degli Studi Di Milano''</ref>, cold fusion <ref>Andrea Rossi and Professor emeritus in physics Sergio Focardi in their patent application, Page 12: ''the reaction actually provides a true nuclear cold fusion.''</ref> of hydrogen and nickel was taking place in the reactor, leading to the formation of copper.

Andrea Rossi and Sergio Focardi gave a press conference on January 14, 2011 which was not only attended by Italian public television station RAI (RAI&nbsp;3) and numerous journalists, but also by several physicists from universities. In an adjoining room, the function of the reactor was demonstrated for only a few minutes. The inventors reported this in their blog<ref>http://www.journal-of-nuclear-physics.com/?p=360</ref>, and published three Youtube videos in Italian language [http://www.youtube.com/watch?v=z-0WvK2b7dU], [http://www.youtube.com/watch?v=u-Ru1eAymvE], [http://www.youtube.com/watch?v=dmHZrhTQhUc].

Andrea Rossi and Sergio Focardi gave a press conference on January 14, 2011 which was not only attended by Italian public television station RAI (RAI&nbsp;3) and numerous journalists, but also by several physicists from universities. The presentation was done in rooms rented from the company "GM System" in an industrial area of Bologna<ref>Firma GM System, Via dell'Elettricista 16, Bologna</ref> and not in rooms of the Bologna University as claimed on various places in the internet.

 

During the press conference the function of the reactor was demonstrated for only a few minutes in an adjoining room. Varying durations for the experiment between 15 and 40 minutes are available. A close look at the measured data on the screen of a laptop allow to conclude a for duration of 15-20 minutes the water temperature was higher than 100 degrees (see image). In the report about the experiment the data, which are seen on the notebook are omitted. The report also speaks of a duration of 40 minutes, obviously the whole duration including heating up is meant. The inventors reported about their experiment in their blog<ref>http://www.journal-of-nuclear-physics.com/?p=360</ref>, and published three Youtube videos in Italian language [http://www.youtube.com/watch?v=z-0WvK2b7dU], [http://www.youtube.com/watch?v=u-Ru1eAymvE], [http://www.youtube.com/watch?v=dmHZrhTQhUc].

During the press conference they stated the heat input was 600&nbsp;Watts, at an estimated output of 12,000&nbsp;Watts (12&nbsp;kW). Inventors calculated the heat generated from heated water: 292 grammes of water per minute were heated from 20 degrees to 101 degrees (dry vapor) and evaporated. The attending physicists were allowed to take some measurements. They were disappointed, however, as a spectral analysis of the gamma radiation was denied due to secrecy reasons. A detailed report submitted by independent physicists from Bologna University stated that no gamma radiation was detected, although the device was supplied with two openings for measurement purposes. Excerpt from the report:

Excerpt from the report:

:''[...] no gamma radiation above the background level in the energy region Eγ > 200 keV has been observed, neither in single counting, not in coincidence;<br>regardless of the internal details of the reaction chamber, shieldings and other industrial secrets, the γ rates measured with the NaI counters seem not compatible with the rates deduced or expected assuming that the energy production was due to nuclear fusion or decay reactions, as suggested in [1].''

Observers were allowed to weigh the hydrogen gas container before and after the experiment (weight: 18.6 kgs). Even considering possible errors in measurement (duct tape still attached), hydrogen usage was estimated at less than one gramme, not enough to make conventional hydrogen combustion plausible. Link to the report: [http://www.psiram.com/doc/Levi%2C_Giuseppe_-_Report_on_heat_production_during_preliminary_tests_on_the_Rossi_Ni-H_reactor_%282010-2011%29.004810.pdf] The estimation of energy by evaporation of water was criticized in retrospect, as respective calculations were made based on dry vapour without fractions of condensed water which was not proven. The throughput of water claimed at 29 mls/min. was doubted, too, as the pump used allegedly had only half of this capacity.
