Here’s another comment from today on the topic, when Rossi was asked the kind of problem they are dealing with:

Component failures. We must invent a component that does not exist, but we are close to resolve the problem. I cannot disclose the particulars of the problem.
Here’s a little indication about what kinds of issues Andrea Rossi and his team are working on with the

Dear Dr. Andrea,
I have followed your progress for many years from afar. But recently my excitement is overwhelming. Regarding your current efforts with the E-CAT SKL are the issues you and your team are working related to:
A) Stabilizing the plasma to produce consistent electricity?
B) Resolving issues with the control system to consistently produce electricity? Or,
C) Working issues more related to commercialization such as ensuring a long run time?

D: reliability in long time
I think what Rossi is meaning here is that they are working on reliability over the long term. It is one thing to have the SKL to run for a short period of time, but for commercial products you would need to have them working reliably. There was a question on the Journal of Nuclear Physics this week asking about having the grid as a backup for the SKL:

When it will be possible to use the Ecat as a main energy source do you think it will be opportune to maintain the grid as a backup ?

We have heard from Rossi that the heat-only E-Cat SK, has had reliability problems during its operations for about a year now, and maybe there is something inherent in this technology that is causing problems, so having a backup source of energy maybe a requirement until problems are resolved. We are in very early days for this previously unknown energy source an it is probably not unsurprising that there are problems to deal with.
