The Energy Catalyzer (often referred to as the E-Cat) is an invention of Italian-American inventor Andrea Rossi which has been found to generate anomalous amounts of excess heat when a reactor containing nickel powder, hydrogen and other elements are exposed to an external source of heat. Andrea Rossi states that the excess heat is generated by a low energy nuclear reactions (LENR) process, but so far has not provided a theoretical explanation of how the E-Cat works.

Andrea Rossi became interested in the topic of LENR shortly after the 'cold fusion' announcement by Martin Fleischmann and Stanley Pons in April 1989. Rossi says he tried without success to replicate the Fleischmann and Pons experiment, but maintained interest in LENR and began to try his own experiments. In 1997, working in New Hampshire, USA, Rossi reports that he first noticed the production of excess heat from what he considered could be a nuclear reaction[1]

Eventually Rossi collaborated with University of Bologna physicist Sergio Focardi who helped him with the development of the E-Cat. Focardi had worked with University of Siena biophysicist Francesco Piantelli in the early 1990s who had been experimenting with LENR reactions in nickel-hydrogen systems. Rossi says that Focardi was particularly helpful in helping him develop safety systems for E-Cat reactors, and in teaching him mathematics.

On January 15, 2011, Rossi and Focardi introduced the E-Cat at a press conference at the University of Bologna in which they carried out testing of the E-Cat and answered questions [2]. Since that time, Rossi has continued to develop the E-Cat, and has carried out various demonstrations, and made the E-Cat available for third party testing.

In January 2014, Raleigh North Carolina company Industrial Heat, LLC announced they had acquired the rights for Rossi's E-Cat technology, and Andrea Rossi states that he now works as chief scientist at Industrial Heat. Rossi has stated many times that he is currently testing a commercial E-Cat plant in the factory of a customer of Industrial Heat, but there has yet to be a working commercial product made available for public viewing. Rossi has said that this plant would produce 1 MW of energy in the form of steam which will be used in an unspecified production process.

On February 18th, 2015, Andrea Rossi released some photographs of this 1 MW plant on his personal website, Rossi commented on The Journal of Nuclear Physics, that the photos were taken while it was being manufactured. Regarding the photographs, Rossi said:

"The plant is much more complex than appears in the photos, but they give an idea of the thing, though. No more photos will be produced until the tests will be finished."[3]

In May 2015, another photograph was released which shows Andrea Rossi listening to the internal sounds of an E-Cat reactor in the plant he is testing.
