Cold fusion is an energy source that could provide clean water to Planet Earth, zero-emission vehicles with unlimited mileage, a solution to the climate crisis and much more. It is clean, compact, simple, inexhaustible and . . . physically impossible. At least that is what science has considered since 1989. But in January 2011 the Italian inventor Andrea Rossi demonstrated a sloppily-wrapped device that boiled water with heat emanating from something that seemed to be cold fusion. Too good to be true, some said. Fraud, according to others. A Swedish technology journalist was one of the few who chose to take Rossi seriously. In An Impossible Invention we follow his search for the truth about Rossi and the strange device — the E-Cat. He shows that the impossible seems to be possible, that the world faces fundamental change. Mats Lewan is a technology and science journalist, author and speaker.
