The Energy Catalyzer technology, engineered by Andrea A. Rossi and based on the nickel-hydrogen exothermic reactions pioneered by physicist Francesco Piantelli, Sergio Focardi, and others since the 1990s, was tested in Bologna, Italy.
Around the world, scientists active in cold fusion research, along with new-energy enthusiasts, waited for word from the invitation-only demonstration participants. It was believed that scientists from several countries, including a European patent examiner would be attending the reactor run, taking measurements and disassembling the reactor to prove the design’s integrity

Continuous real-time updates can be found at the Pure Energy Systems special page dedicated to this demonstration.
While the bulk of the information and photos are scheduled for Friday release, 22Passi’s tweets describe an E-Cat running for about 4 hours in self-sustain mode, the condition where the E-Cat is not connected to any external source of power, and the reaction continues indefinitely. If true, and there is no reason to doubt the veracity of that report, this will be a huge victory for Mr. Rossi and his partners, and a successful show of the first cold fusion clean energy technology.
Self-sustain mode was ended purposefully in order to allow the device to cool down for disassembly. Allowing scientists to view the inner components of the E-Cat will prove, at least to those present, that there is no additional input power to the reactor other than the nickel-hydrogen reaction chamber itself.
Some as yet unconfirmed data compliments of Raymond Zreick’s tweets include “the steam was always kept above 110 degrees” and a cryptic “from 15 to 19 the difference in average temperature was 5 ° C (water inlet and outlet water), for 0.6 cubic meters / hour”. That sentence may mean from 15:00 hours to 19:00 hours the difference between the ambient temperature of the incoming water and the Energy-Catalyzed hot outgoing water was 5 degrees with a volumetric water flow of 0.6 cubic meters per hour. This is the data needed to compute the thermal energy generated by the E-Cat reactor and, if true, indicates a very good output of energy.
Multiplying the total mass of the water that went through the reactor in self-sustain mode with the specific heat of water and the change in temperature will give you the amount of energy used to perform that work in joules.
Change in temperature of $\Delta T = 5^\circ$ for $2400$ kilograms of water, using a specific heat of water of $4.2 \text{\hspace{0.7 mm}kJ/kg \hspace{0.7 mm}} \cdot \text{\hspace{0.7 mm}}^\circ C$ gives
$(5^\circ) (4.2) (2400 ) = 50,400 \text{\hspace{0.5 mm} kiloJoules of energy}$.
These preliminary numbers show an energy of 50.4 Megajoules of energy expended to heat the water. Dividing the energy above by the total time 4 hours = 14,400 seconds gives
$\frac{50.4 \text{\hspace{0.7 mm} x \hspace{0.7 mm}} 10^6 \text{\hspace{0.7 mm} Joules}}{14,400 \text{\hspace{0.7 mm} seconds}} = 3500 \text{\hspace{0.5 mm} Watts}$
or, a power of 3.5 kiloWatts, where power is the energy delivered each second of operation. We look forward to confirmed details tomorrow from Mats Lewan.
Some of the media in attendance included Radio24’s Mauricio Melis, Irene Zreick and Raymond Zreick of Focus Magazine, and Radio Città del Capo who interviewed Greek scientist and former ambassador to Italy Christos Stremmenos also there to see the demonstration. Confindustria, an organization representing the manufacturing and service industries in Italy, and Enrico Billi was also reported in attendance.
Italian scientists Sergio Focardi, Giuseppe Levi and Loris Ferrari from the University of Bologna, where the event was held, were also joined by other unnamed physicists invited by Professor Focardi.
Corporate media in the US have ignored developments in cold fusion and there appears to be no coverage on Mr. Rossi’s E-Cat technology at all. However, Wired magazine published an article about today’s demonstration online at their UK site “Cold fusion rears its head as ‘E-Cat’ research promises to change the world“.
When one nickel in your pocket can generate E-Cat energy equivalent to 5 barrels of oil, you can be sure it will change the world.
