Indeed I am not able to find any other reason. But we have to be still skeptical. But in case that there is any error, it was repeated very well.
Tommorow I want to refuel it. It is not possible right now, because humidity is 90% at the moment.
I am very curious, if it will be possible to get higher COP with higher pressures.
In case that it is really LENR, then adding pure Lithium can boost it extremely. Because of this, I want to buy Neutron detectors as soon as possible.
Rossi have found the limit so that Neutron emmission is very low. It is possible that one day we will get uncontrollable reaction which may be really dangerous.
From my point of view LENR may be very safe, but if you want, you can make really bad things.
