LENr was proven properly, that is a fact.
the problem is that this "properly" (50 sigma, >50% success, correlation of heat and He4, transmutations, replications) is not enough for a kid of 5 years old.
The few big power experiments are not clear, even if circumstantial evidence, correlated with LENr reality in the lab, make unreality of industrial development very improbable.
don't mix bad will and incompetence with absence of evidence.
we lack of industrial grade evidence that can convince dishonest people.
science cannot convince dishonest observers, that is not new.
Never forget some people deny Apollo landing. Denial of LENR is of the same kind, just more popular and supported by media authorities.
