On the Journal of Nuclear Physics today a reader asked Andrea Rossi what the current status of the E-Cat in terms of Technology Readiness Level (TRL) is.
Technology Readiness Level is a scale developed by NASA that estimates that maturity of a technology, ranging from 1-9. See the following image found on Wikipedia.
Here is the Q&A from the JONP:

Dear AndreaIn which TRL do you consider that the first versions of a complete Ecat aggregate are in today?
When do you assume that TRL 8 and 9 will be achieved?Regards Svein

Svein:
I think that the Technology Readiness Level of the Ecat as for today is 8 for global applications, 9 for big facilities industrial applications, as counter-intuitive as it might be,
Warm Regards,
A.R.
Rossi seems to think it is ready now, at least for industrial applications, which indicates to me that the current installation and testing is going well.
UPDATE: Here is a follow-up question I asked this morning, and AR’s response:

Dear Andrea,According to EU definition, a TRL of 9 means “actual system proven in operational environment”
Can we then assume from your answer to Svein today (TLR of 9 for big plants), that an industrial E-Cat plant has been shown to operate successfully?

Frank Acland:
Yes, but under strict control,
