The LEC effect contains serious irony. For the electron emission to be produced, the cold fusion nuclear reaction must occur. Therefore, the LEC observation is important because the electron current is easier to measure at much lower rates than any other diagnostic for LENR. Consequently, Gordon's experience demonstrates that LENR is much easier to produce than previously thought, although only at very low rates. While the electrons have no practical value, they do provide an easy way to demonstrate that LENR is actually happening.
The same irony applies to the use of high temperatures. LENR is very sensitive to temperature. As a result, many of the failed attempts done at room temperature would have been successful if the temperature had been increased. Sadly, McKubre worked hard to keep the temperature in his calorimeter constant, which denied this important insight for many years even though Fleischmann said that increased temperature was important.
The problem now is the absence of the correct description of the conditions required to produce LENR and its mechanism. This flaw will not change because the leadership in this field is no longer able to change their beliefs as new behaviors are discovered. We are now seeing the same rigid beliefs inside the field as is a problem in general science. The ability to ask questions and explore new ideas has been lost.
