Brief Summary of Latest Experimental Results with a Mass-Flow Calorimetry System for Anomalous Heat Effect of Nano-Composite Metals under D(H)-Gas Charging

A mass-flow calorimetry system has been installed to investigate the excess power phenomenon at elevated temperatures. The first trial runs with a silica-included Cu center dot Ni nano-composite sample (CNS) containing 4.1 g of Ni showed an implication of a few days lasting excess power of 5 W/g-Ni. Next, a Cu center dot Ni center dot Zr oxide nano-composite sample (CNZ4) containing 61 g of Ni has been examined to show excess power of 15 W lasting for 3 days and gradually increasing at a rate of 10 W per 3 weeks. Each corresponds to 30 eV/atom-Ni and 100 eV/atom-Ni, implying a nuclear origin of the excess energy.
