Today Andrea Rossi posted this announcement on the Journal of Nuclear Physics:
October 4, 2023 at 9:23 AM
Today we had a major problem with the Ecat System of the EV, and we have presently serious difficulties to understand how to fix it. It is an issue that involves safety issues, therefore we have stopped all the Ecat in operation, included the Ecat that has been streamed until about 9 A.M. this morning.
The event of October 20 has to be delayed until we resolve the problems.
Obviously we will keep you updated in the time being.
Obviously, this announcement will be disappointing to some who had been hoping to see the demonstration take place this month. It is interesting that the livestreaming of the light has been stopped also. I am sure will be a lot of speculation about what could have happened. Perhaps there was an unexpected accident or critical failure. Hopefully we will get more information about it.
