[ summary of critique: science that purports to establish a notable percentage increase in excess heat as a reproducible anomaly, as reported herein, is very lacking re many critical details and shows lack of common sense consideration of reasonable complications -- as usual in LENR research, an enthusiastic team created a "black" witch's cauldron, full of impurities, sealed and invisible to detailed observation during months of cooking in H2 gas at high temperatures. Probably, corrosion opened up additional conducting paths, reducing the total electrical resistance fed by the constant voltage power supply, increasing the total input electric power via increased current flow, which increased ordinary electric heat effects in complex ways within the black box. So far, the surge of enticing, but vague, thin, and variable information follows the pattern of the Rossi debacle in 2010-2011... ] [ search http://www.lenr-canr.org/ Piantelli to get 5 pages of items that include many full text papers ] http://www.lenr-canr.org/acrobat/FocardiSlargeexces.pdf 10 pages IL NUOVO CIMENTO VO L. 111 A, N. 11 Novembre 1998 1233-1242 Large excess heat production in Ni-H systems S.

The phenomenon occurs when a cell containing a nickel rod is maintained at temperatures above a critical value and is filled with gaseous H2 at subatmospheric pressures. A constant input power was used to raise and keep the cell temperature constant at its working value (corresponding to about 700 K for the Ni rod). It was possible to induce an increase of the sample temperature from its working value to about 820 K. This anomalous equilibrium condition will be referred in the following as excited state. The system was able to remain in the excited state for several months. The experimental cell described in ref. [1] was successively modified and also a new cell was built with an improvement which allows the measurement and the monitoring of the external surface temperature. With this new set-up, the external temperature increase, together with the internal one, have been utilized to characterize the excited state of the Ni sample. The existence of an exothermic effect, whose heat yield is well above that of any known chemical reaction, has been unambiguously confirmed by evaluating the thermal flux coming from the cells. An important feature of our systems is that they can remain in the excited state for a long time. This characteristic allowed us to search for ionizing radiation coming from the cells. Very clear evidence of neutrons and -rays has been reported by us [2-4]. Systematic studies of such processes and their correlation with heat production are in progress. ..... much more...
