A "Hot-Cat" is the high-temperature version of the E-Cat, the Energy Catalyzer invented by Andrea Rossi, a reactor which provides clean energy at an extremely low cost. The first step to be taken in order to replicate in your laboratory a so-called "Hot-Cat 2.0" - i.e. a last generation Hot Cat - is to understand how it is done and what are the differences between an original "low temperature" E-Cat and a modern Hot-Cat. Reading this book, the reader will understand perfectly how the new Hot-Cat 2.0 is a much more sophisticated apparatus than you might imagine from an its superficial analysis. The book is aimed primarily at those who, having already understood the basics of an E-Cat, want to move on to an industrial product, or, that is to say, a second-generation E-Cat, requiring a better knowledge of the E-Cat technology. Many people still think of the E-Cat with old patterns, but the evolution of this product has finally led from what was apparently a rudimentary reactor prototype to a real small gem of science and technology.About the Author: ROBERTO VENTOLA is a 38 years old Italian Electrical Engineer. With over a decade of experience, he is currently working in a multinational company manufacturing electronic equipment, particularly in the computer field. He has a strong foundation in mathematics and possesses the creativity needed to develop projects regarding new technologies. His dream? To be the first to replicate a second-generation Hot-Cat. VESSELA NIKOLOVA, psychologist, lives in Tuscany, Italy, and is already author of a book, E-Cat - The New Fire, the biography of Andrea Rossi. She founded and now manages a blog about Low Energy Nuclear Reactions (LENR) and the E-Cat, touching on new themes in technology, targeted at an international audience.
