Abstract
The authors developed an innovative method to induce anomalously large heat generation phenomena that cannot be explained by known chemical processes. Ni-based nano-sized multilayer film is preloaded with hydrogen gas and heated rapidly to diffuse hydrogen and trigger the heat generation reaction. Two nano-sized metal multilayer composite samples, which were composed of Ni, Cu, and the other thin films on bulk Ni (25 mm ⇥ 25 mm ⇥ 0.1 mm), were used. Anomalous heat generations were observed during the experiments under vacuum condition (<104 Pa) using nano-sized metal multilayer composites on Ni substrate, with hydrogen gas. Released energy evaluated with total amount of absorbed hydrogen reached to more than 10 keV/H. In addition to steady-state anomalous heat generation, spontaneous heat burst phenomena were sometimes observed. Based on the observation of spontaneous heat bursts, we can now trigger intentional heat bursts. The energy from even a single heat burst exceeds the energy produced by any known chemical reactions. Observation of heat bursts has improved the reliability of excess heat experiments. Samples that generated excess heat or heat bursts often show some areas of very high oxygen concentration after the experiment according to SEM-EDX and TOF-SIMS analyses.
