That is true, but once it heats up you can turn off the heat input. > What controls does he have to make a useful system? I do not know if it is useful, but it can be run without input.

During the 4-hour run with no input, the temperature rose twice.

I doubt that external heating would be a good method of control. Celani has greatly reduced his input power since ICCF17, with no apparent decrease in control, so I do not think external heating is a method of control. > Jed, you are entitled to your opinion just like everyone else.

That is a matter of fact, not opinion. Many people have done this, with Pd and Ni. Even if you distrust Rossi's claims, many others have done this. You cannot argue with replicated experimental data. I have not heard that systems in heat after death tend to go out of control. - Jed
