Japanese Team Reports Anomalous Heat Generation from Nano-Structured Metal Composites and Hydrogen Gas System

Thanks to a reader for letting me know about an article published this month (March 2024) in the Japanese Journal of Applied Physics in which a team at Tohoku University in Japan have reported anomolous excess heat production in a system using nano-structured multilayer metal composites and hydrogen gas.

Article Title: “Anomalous heat generation that cannot be explained by known chemical reactions produced by nano-structured multilayer metal composites and hydrogen gas”

Authors: Yasuhiro Iwamura, Takehiko Itoh, Shinobu Yamauchi and Tomonori Takahashi

Abstract:

Anomalously large heat generation phenomena that cannot be explained by any known chemical processes were discovered: Ni-based nano-structured multilayer metal composites were preloaded with hydrogen gas and heated rapidly to diffuse hydrogen and trigger the heat generation reaction. Maximum energy released per total hydrogen absorption was over 10 keV H–1 and no gamma rays or neutrons, which are harmful to the human body, were observed. It is possible to intentionally induce the heat burst phenomenon, which can increase the amount of heat generated without any new energy input. This can be applied to reaction control as well as to improving the accuracy of heat generation evaluation. A common feature, that regions of very high oxygen concentrations are observed in places, was observed in the heat-producing samples. At this time, however, the discussion of this oxygen concentration as nuclear in origin must exclude the possibility of many chemical processes.

There is also report on the New Energy Times website about this article which includes analysis of the article and some comments from Yasuhiro Iwamura, one of the article’s authors:

“Iwamura told New Energy Times that the integrated value of the input electric power during the entire experiment was 4.8 MJ. The total output of heat generation during the experiment was 5.56 MJ, resulting in a net thermal output of 0.76 MJ.”

Iwamura stated that the experiment has been repeated around 200 times.
