Cold fusion has always been a controversial scientific topic since its inception in 1989 by Martin Fleischmann and Stanley Pons of the University of Utah where the scientists claimed to have observed 1.75watts more heat compared to their input power. Failure to replicate the result of their experiment brought cold fusion into the dark. It became too infamous that government funding was impossible and encouragement from other scientists was next to none.

The theory has been reintroduced only in 2009 after a convention conducted by the ASC where scientists from the US Navy presented evidence of cold fusion. The panellists in the convention have said that there are other scientists who dedicated their studies to cold fusion but they didn’t get public attention as their works were only published in peer-reviewed science journals and their websites.

150 published works were noted according to Edmund Storms, a retired nuclear scientist from Los Alamos National Laboratory and author of The Science of Low Energy Nuclear Reaction (World Scientific, 2007), and one these is Sergio Focardi’s studies and Andrea Rossi’s invention of the e-cat device.

Though e-cat device’s potential to be used as primary energy source has captured many, it has not been fully explained how nuclear physics fit in the picture when hydrogen nuclei can only come close to each other when they overcome their strong electric repulsion and can only be done when the nuclei are squeezed into a really small space and under high temperatures up to tens of millions of degrees. Also, this is only possible with the use of billion-dollar hot fusion reactors which the stars are also capable of doing. So, in order to even think about when to buy e-cat for home use, is still only a theory.

With a tabletop set-up and cheap source of materials, cold fusion experiments now give us hope to lower e-cat prices would be available even to the homes of average citizens. Research is now dedicated to revealing all e-cat secrets. However, Steve Krivit, editor of the online LENR newsletter New Energy Times believes that a more concrete theory is needed to make cold fusion clearer because all there is are experimental evidence.

E-cat is however something to watch out now that cold fusion has gained more supporters. Mr Ludwik Kowalski, a retired physics professor at New Jersey’s Montclair State University, said that throughout the 1990s and into the 2000s, he was as skeptical as anyone when the topic of cold fusion came up until he himself performed the experiment published in the earlier papers of US Navy and got exactly the same results using CR-39. “Now even I think there are serious indications that there is something behind this,” he said on an interview. Years after, the e-cat device has been launched and e-cat prices have been set. The e-cat prices are competitive despite its promise of a greener source of energy.
