According to latest discussions on the Journal of Nuclear Physics, Rossi himself has confirmed that his high heat unit has achieved self-sustained mode.
The self-sustained mode is more or less the “Holy Grail” of energy research. When a source of energy is self-sustaining, it means that it can run indefinitely without the use of external fuel sources, or the introduction of another catalyst.
The E-Cat 600C is, according to Rossi himself, running at self-sustained mode for about 50% of the time.
Dear Hank Mills:
Basically I agree with you.
About 50% of the time goes self sustained in our tests.
This self-sustaining mode is good news for those who want to go completely “off the grid” with their energy consumption. Those who don’t want to depend on coal-burning power plants at all will welcome the opportunity to start their E-Cat and then just allow it to run.
When asked if infinite COP, or self-sustained mode, would mean loss of control of the energy output, Rossi said, “No.” This implies that the inventor has developed a method of controlling the reaction taking place, exclusive of the external catalyst.
Currently, it is assumed that the reactions taking place in the E-Cat can “run away” to the point where the nickel would overheat and melt, stopping the reaction completely. The E-Cat reaction must be stabilized, and further assumptions are that this is done through electrical resistors.
Rather than the E-Cat needing electrical input as fuel, it must need periodic electrical input to control the reaction.
However, Rossi still remains closed-mouthed about the core catalyst. International patents aside, this is probably a good idea on his part. Achieving self-sustained mode is a major step forward for an invention aiming to change the energy system.
