Thanks to Michelangelo de Meo for posting about the following on the Journal of Nuclear Physics.
Researchers from Technova Inc. Nissan Motors Co., Kyushu University, Tohoku University, Nagoya University and Kobe University in Japan have published a paper in which they report on research activities conducted between October 2015 and October 2017 in which they have been carrying out experiments in search of excess heat in reactions between hydrogen and various metals.
A link to the report is here.
Heat measurement were carried out with an oil-mass calorimetry system that has been set up at Tohoku University, and 16 different experiments have been carried out over the course of two years.
The experiments have found that excess heat production (assumed to be non-chemical) in some of the experiments which have been carried out with various metals at different temperatures. The report states:
Form these obtained knowledge, we will be able to conclude that Ni-based multi-metal nano-composite samples are of very required necessary condition for generating sustainable high intensity heat-power generation at elevated temperatures more than 200°C. It is encouraging towards industrial application of thermal and electric power devices.
The researchers state that a full-length report has been published in Japanese language only.
