Résumé

La production d’excès d'enthalpie dans le système Pd/LiOD, ainsi que pour les alliages du palladium dépendrait du protocole expérimental et celle-ci serait due à un "feed-back" positif. Nous décrivons ce protocole et nous donnons une interprétation du "feed-back" positif.

Le développement de l'étude conduisant à l'obtention de taux spécifiques de production d'excès d’enthalpie de [math] 4kWcm^-3, est illustré jusqu'aux températures de [math] 100 °C (c. à d. de chaleur de basse temperature)

Abstract

We outline some of the considerations which have prompted our search for anomalously fast nuclear reactions of D+ compressed electrochemically into Pd (and Pd-alloy) host lattices. The most surprising result has been that the generation of high levels of excess enthalpy is not accompanied by the expected levels of tritium and of neutron generation. We outline some of the major steps in the development of this particular aspect: it has been found that excess heat production is dependent on the protocol of the experiments mainly because of "positive feedback". A rationale for such "positive feedback" is presented which also explains oscillations in the system properties. We illustrate the progressive development of the investigation leading to the achievement of specific rates of excess enthalpy production of [math] 4kWcm^-3 at temperatures up to [math] 100°C (i.e. of low-grade heat).
