interesting follow up on Guglielmi’s blog
>>The only response for which Prof. Essén authorises publication is the following:
“In the intervju I answered that there was no direct measurement of dc (since the clamps could not detec such). This was a bit hasty. In future I will not answer such technical questions without conferring with all coautors. After analysing what we checked and measured (which were many more variables that those from the clamps) we can definitely exclude dc-current. (This is what comes from being nice to journalists.)”<<
So the testers are quite confident that if they have been had by Rossi, it is most likely not due a secret DC current.

Oto odpowiedzi prof. Hanno Essena (ktore przekazuje na ChemFana za jego
wiedza i zgoda):

I do not know the answers to the first questions. We had a picture of
the internal reactor in the original manuscript but it was deemed to
uninteresting. It is just a steel pipe.

I suppose that this is because the material is not sufficiently
transparent to the microwaves. They originate from the surface; there
is no see through.

It was not. It was carried out with everything as equal as possible.
The on/off mode was due to a thermostat that prevented the reactor
getting too hot and this was not relevant in the dummy test.

No, we did not think of that. The power came from a normal wall socket
and there did not seem to be any reason to suspect that it was
manipulated in some special way. Now that the point is raised we can
check this in future tests.

I do not know this since only the Bologna group was there when that
happened. I take for granted that also the Ni melted and that the
reaction stopped, but the interior physics is still an industrial
secret that we do not have access to. Sorry.

Andrea will not part from his device. Tests in Sweden is a possibility
but then he or his coworkers would be present. There are many who wish
to steal his e-cats. So the 6 month test will be in Ferrara. It will
however be continuously monitored by cameras so as not to be
manipulated.

This is a question for Prof. G. Levi who provides the instrumentation.
It is desirable, I agree; everything can always be done better, but we
have very limited time and resources unfortunately.

I do think that the plan is precisely that.
