There was an interesting revelation from Andrea Rossi this weekend on the subject of self-sustain mode (SSM) with the E-Cat. Recently Rossi had stated that SSM is much easier to achieve with large MW scale plants that with the smaller units.
Here is a Q&A on the topic:

Steve D:
1- Based on the last developments, the SSM is possible only for plants with a power of megawatts
There was another exchange about what the failure rate was in the 100 W units:

Prof. Neri Accornero:
Understood, yes the percentage of malfunctions are still around the 5%, which is high for a mass production; this is one of the reasons why we are afraid of a massive distribution in market areas oriented toward non professional users. Paradoxically, we are more afraid of households appliances than of 4 MW plants.
Warm Regards,
A.R.
A 5% failure rate that would be very unacceptable for consumer products. Perhaps the reason for the MW focus is because redundancy can be built in to make up for failures in individual units.
What this all means for the plans for smaller E-Cat generators is not clear at the moment. It may be that they will be shelved for the time being, or that non-SSM grid-connected units will be necessary for domestic applications.
