Preliminary investigation of possible low-temperature fusion

Journal of Fusion Energy (Impact Factor: 0.99). 05/1990; 9(2):115-119. DOI: 10.1007/BF02627576


Preliminary tests have been made with electrolytic cells utilizing 0.2N LiOD in D2O as the electrolyte and a palladium cathode surrounded by a wire-wound platinum anode operating at cathode current densities
of 100–400 mA/cm2. The cathodes were swaged to diameters of 2.8 or 5.5 mm with 8.5 cm of active length. The electrolyte temperature was controlled,
heat was removed by flowing water in a cooling jacket, and the cell was insulated. Cooling water and electrolyte temperatures
were measured by thermocouples, and neutron and gamma-ray spectra were recorded. The electrolyte level was periodically monitored
and replenished with D2O. Tests up to 2 weeks in duration were made with no sustained release of energy in excess of the electrical power input,
although there was one period of 12 h when an unaccountable heat excess was observed. In another test, an anomalous neutron
flux was measured during the first few hours that was 3.5 standard deviations above the background.

    ABSTRACT: This document contains a tally of cold fusion papers from two sources: the list maintained by Dieter Britz at Aarhus U., and the EndNote database used to generate the indexes at Various tallies such as the number of peer-reviewed experimental papers are presented. Purpose This report presents some background and a breakdown of the items in two databases of cold fusion papers: the Britz collection, and the LENR-CANR database. The purpose is to give the reader a sense of the scale, variety, and sources of the material available about this subject. This is also intended to give some indication of how much has been published on cold fusion, where it was published, and approximately how many positive and negative papers have been published. This paper includes the following tallies: 1. Summary statistics for the LENR-CANR database 2. Positive, peer-reviewed excess heat papers culled from both databases. 3. Papers from Britz collection. 4. Famous failed neutron studies from 1989. These had a large influence on scientific opinion and the subsequent history of the field, but many cold fusion researchers believe they were flawed and should not be given weight today. Details from these four tallies are gathered in Appendix A. They include multipage lists of journal titles, authors and the individual titles of papers referenced in the four tallies.

    ABSTRACT: One hundred sixty seven papers from 1989 to 2007 concerning the generation of heat from electrochemical cells were collected, listed, and digitally posted to a CD for reference, review and study. A review showed four criteria that were correlated to reports of successful experiments attempting replication of the Fleischmann-Pons effect. All published negative results can be traced to researchers not fulfilling one or more of these conditions. Statistical and Bayesian studies show that observation of the Fleischmann-Pons effect is correlated with the criteria and that production of "excess heat" is a real physical effect "beyond a reasonable doubt."

    ABSTRACT: Cross correlations as a function of timeshift between -emissions and electrolysis cell temperature, in a cold fusion experiment by Birg├╝l et al. are calculated and show a distinct maximum of 0.34.
