The first technical book on the E-Cat technology has just been published! The title is “HOT-CAT 2.0: How last generation E-Cats are made” and it is a valuable introduction to the more advanced reactor devices developed by Andrea Rossi and Industrial Heat.

From the Preface by Vessela Nikolova:

“I want to be absolutely sincere: this book was written by Eng. Roberto Ventola (a contributor of this blog), who has a technical background, and I appear undeservedly as an author. Therefore, I want to tell the reader how things really went.

Seeing as Eng. Ventola sent many technical articles to be published on the blog and I could not publish them all together, I suggested collecting and publishing them in a book, an idea that he enthusiastically agreed on, offering – in exchange for this opportunity – to donate half of the earnings to Vessy’s Blog Fund through my co-authorship.

Since my blog is financed only with free contributions coming from generous readers and sponsors, and because this is essential for its future survival, I have agreed to appear as co-author. However, my real contribution was only to standardize the style of the book to that of previously published articles and to make a few public communications.

I am very happy to have contributed in some way to the birth of this work, which I think will remain for many years as a reference book for all those who are seriously interested in the last generation Hot-Cat. It is a bit more technical than my book ‘E-Cat – The New Fire’, but I’m sure that most of readers will be able to appreciate it.

Despite the fact that I am not able to assess its more technical content, it nevertheless seems very intellectually stimulating reading to me, enhanced by about 115 figures that enrich the text, making it almost unique. I hope that this is really the beginning of a world energy revolution, though at this point many new characters will need to appear on the scene”.
