Let´s assume Andrea Rossi is right and the e-cat actually works, and his e-cat patent is  sound. We are not excluding this possibility, neither do we exclude it may be a hoax. If it is a hoax it would be certainly the last hoax of that kind. Customers who purchase the 1 MW e-cat will soon find out if it works. Many scientists think it must be a hoax, not only because there is no accepted theory to explain the effects, but also because of the secretive black box approach of the inventors and very speculative explanations of the effect.

We have examined Mr Rossi´s e-cat patent application a little deeper, the patent filed under WO2009125444 and US2011/0005506.
