Recently a video interview conducted with Rossi revealed that gamma rays have been detected and he was also asked whether his technology is indeed cold fusion. Gamma rays have been detected, which means that there is a risk of radiation, or so everyone would think. But Rossi stays rather cool and reserved, claiming that they’ve got the gamma ray issue under control, so much so in fact that goes as far as to say that “there will never be any kind of gamma emission.” He does not go into details as to how gamma rays have been tamed, but he does state that his E-Cat device is safe to install and use in home environments without any threats to human life.
When it comes to the question of the E-Cat fusion, it does seem to be happening, but whether it can be defined as cold fusion or not, the inventor did state that “they have found 511 kev gamma rays at the output… so we have some kind of fusion inside, but I do not think this is the main energy source.” So E-Cat fusion does take place, but so far it remains a mystery. On the other hand, though, it’s not like it’s the first mystery in the saga of Energy Catalyzers. E-Cat fusion, although a different kind of mystery, can be lumped together with the secret catalyst that Rossi employs for his nickel and hydrogen reactions, with the unidentified customer(s) of his and many other things that are yet to be brought to the light. In the meantime, however, we are assured that no radiation is going to leak, and these are not just statements, but a result of “thousands of hours of tests” that Rossi and his men made.
