Andrea Rossi made an interesting statement today in response to a question about the secret catalyst which plays such an important role in his E-Cat reaction. Rossi rarely provides any information when asked about this topic, but today he did say something:
Q: The catalyst that you guard so well — is it a catalyst in the chemical sense? That is — changes in rate of a chemical reaction due to the participation of a substance called a catalyst.
A: No, we call it a catalyst, but it is not a chemical catalyst.
I know that many people have been trying to figure out what Rossi’s secrets are, and many substances have been guessed at, and even experimented with. This answer indicates that there is more at play than just simply adding an ingredient to the nickel-hydrogen mix.
