Andrea Rossi often interacts with loyal readers of the Journal of Nuclear Physics. Dr. Joseph Fine frequently contributes to the comments section of the blog, providing information for Rossi’s consideration and asking E-Cat related questions that are answerable, despite the confidentiality required by the Italian inventor’s work.
Just yesterday, Fine asked about the adjustment of temperatures on the E-Cat. He asked if the newer models of E-Cats, aka “Tigers”, could be adjusted to operate between the temperatures of 250 to 1000 degrees C, and Rossi’s response is yes. He also revealed that the E-Cat is not limited to only one or two settings for hits heat.
In addition, the Hot Cat can apparently be operated at less than 600 degrees C. This is crucial, because some turbines that may be used to convert the heat generated by the Hot Cat operate best at temperatures between 550 and 600 degrees.
Rossi has also been able to establish a control setting so that the E-Cat’s operating temperature can be set to the desired level. This is in contrast to redesigning the core for each required temperature. This ease of operation is a big plus. In addition, you can change the heat being generated while the unit is running. So, if you want more power or heat, you just “turn it up”. If you want less heat or power, you “turn it down”. This is very much like a throttle or thermostat that governs the amount of operation according to needs.
This is very exciting news. How quickly we have gone from wondering if the E-Cat can self-sustain a reaction to wondering if the amount of reaction could be controlled!

All of this news sounds good and all, however, without un-deniable tangible proof that his machine even does what he says it does… all of this “news” is hearsay. Rossi’s miracle machine sounds more like science fiction than science fact, when the fact of the matter is, without disclosure or an independent test covered by a reliable media outlet, no rational person can believe what Rossi claims with a reasoned confidence.

Not only do many rational persons (see reports and declarations from scientists and new energy journalists) believe in the e-cat, but the support for the e-cat technology seems to reach further and further.

“however, without un-deniable tangible proof that his machine even does what he says it does”
Blah blah blah blah. Yes, we know already. Give it a rest. Nothing is definite until we see the things being sold at home depot.
“no rational person can believe what Rossi claims with a reasoned confidence.”
Oh please. It’s irrational to believe that Rossi is doing nothing but running a scam. It’s quite rational to give him the benefit of the doubt if it doesn’t cost anything, and then quit accepting his word only when 2013 comes and goes without a product.

A question, I was wondering is; “Does an e-cat’s fuel lifetime get extended
as it’s temperature drive is throttled?” This needs an experimental answer.
Be careful before assuming what it is.

This is the problem with a lack of catagorical proof. One has to have a little
mental tag on everything that says; Answer tentative until subject proven true.
