The fact that the E-Cat, developed by Andrea Rossi, is capable of running for months at a time is now established. This continuous operation in itself is a scientific miracle, since LENR is supposed to not even exist. However, the mainstream scientific community is beginning to admit, little by little, that LENR apparently is a true scientific reaction, and with sustained reactions now being demonstrated by Andrea Rossi and other scientists, more questions are being asked about the effects.
One such question is concerning the isotopic distribution levels in sustained reactions. Steven Karels frequently corresponds with Rossi on Rossi’s blog, the Journal of Nuclear Physics, and he recently asked Rossi about the isotopic distribution. He wanted to know if there is a change in the fuel or ash levels. Rossi responded that they had noticed traces of the fuel and ash levels of isotopic distribution, but that they were minute. They were also within the ranges of variation, anyway, so any measurements obtained would be inconclusive.
