You wrote You will need to cite reliable sources for the assertions far too large to be chemical and no endothermic storage events I do not think any source can conclusively estabish either point It is very easy to establish both points and there are hundreds of papers with proof of them 1 The limits of chemical storage electron bonds are well understood The most energy dense chemicals such as gasoline store 4 to 8 eV per atom Cold fusion reactions have often produced far more than this ranging from 100 to 100 000 eV per atom of the material in the cell and in all cases there is no chemical fuel before the reaction and no chemical ash after it finishes Cell with a few grams of inert material in them have produced hundreds of megajoules of heat as much as several kilograms of gasoline if you were to burn the cell contents they would produce only a tiny fraction of the heat In fact you could burn the cell the table and all books in the room and still get that much chemical energy Therefore chemistry is ruled out 2 Any calorimeter can measure an endothermic event as accurately as it measures an exothermic event For example all calorimeters used in these studies show the endothermic formation of Pd D at the beginning of the experiment Since the calorimeters shows the exothermic excess heat they would also show the endothermic storage that proceeds it They have never done this The heat balance is always zero before the heat bursts and after Jed Rothwell HERE IS more useful information that someone keeps erasing Please note that Cal Tech Lewis et al is a false negative as pointed out by Noninski Miles and Fleischmann This is described in several papers for example this one p 20 Also the name is Julian Schwinger with ch See Jed Rothwell Librarian LENR CANR org
