Zhang, H., Summary of abnormal heat release experiment of hydrogen flux vessel. 2020, LENR-CANR.org: Personal Communication
https://www.lenr-canr.org/acrobat/ZhangHsummaryofa.pdf Abstract A container was designed based on the assumption that the abnormal exothermic phenomenon of hydrogen (deuterium) metal is related to the hydrogen flux inside the metal. The container consists of an inner container and an outer container, and the inner container is filled with deuterium or hydrogen. The outer container is evacuated, the inner container is heated, and abnormal heat generation is observed. Both hydrogen and deuterium gas produce excess heat power; deuterium produces more heat, lasting longer. When the inner container is filled with hydrogen a maximum of 5 watts of excess heat power is observed, lasting about 3 hours. When the inner container is filled with deuterium it produces higher power than hydrogen, with maximum excess heat power up to 13 watts, also lasting about 3 hours.
