Mats Lewan: We’re sitting here at the Ny Teknik’s newsroom and have had a conversation about the ‘energy catalyzer’ that is invented by the Italian engineer Andrea Rossi, and is a device that produces energy with something that appears to be a kind of fusion reaction, but maybe we should not call it that.
With me I have Professor Sven Kullander and Associate Professor Hanno Essen who we’ve been talking with, and I’d like to ask you Sven to try to summarize what you think ... what are your considerations on this invention, what do you think about it and how you think we should look upon it at this moment.
(The transcript is edited by Kullander):
Kullander: In this case, you have to believe in the inventor Rossi, who says he has been producing heat without any input of energy except for what you have inside the device. Thus, 100 kWh in ten hours.
And in addition, he has heated a building in Bologna for a year.
And then, the reaction itself, namely the proton capture of nickel, is something completely new in the cold-fusion context, and it should therefore not be dismissed without further investigation.
But the problem is that Rossi, and to some extent Focardi, won’t release any details. It is unknown what the reactor looks like inside, what substances it contains, the patent is not approved, so therefore the experiment cannot be repeated. And therefore the process cannot be scientifically grounded.
The question now is the reliability of the information we have been supplied. But I think we need to continue to monitor the development, because if the experiment would turn out to be true, it gives mankind new ways to gain an additional energy source.
Mats Lewan: What is it that makes you think it may be credible despite the lack of some essential pieces of information?
Kullander: Well, partly because he says it, partly because it is a process that is kinematically perfectly possible (a reaction that produces energy if it really occurs) and partly because he has optimized (the process) in different ways. In the case of nickel powder, for example, he has maximized the surface to optimize the adhesion of hydrogen. On point after point, he has behaved rationally in order to optimize the experimental conditions. On the other hand we cannot from molecular physics and nuclear physics find an acceptable explanation. We need to get more data from the experiment before we can start thinking about explanations.
Essén: What I think is important in this context is that for the first time, so to speak, there is a device which is made in many units and which is being sold, and has been tested by independent people -- input, output -- how much energy that comes in and how much that comes out, in circumstances which these people have controlled.
And that has not happened before in this context. So the physicist Levi believes in this, and the physicist Focardi believes in this, and I believe (their credibility) is above all doubts. It is of course difficult to assess the inventor Andrea Rossi, but there are enough people involved, and enough good data and reports to make it look very seriously at this stage.
Mats Lewan: You have both had the opportunity to send questions directly to Rossi via email, and have received replies. What impression have you got from this dialogue?
Kullander: Well, it has reinforced my impression that he is serious. I find that he is an interesting person to talk to, and I find it hard to imagine that he has indeed created a scam.
Essén: I get the same impression. It seems very unlikely that it is a pure fraud.
