Tadahiko Mizuno and his colleagues have been developing excess heat generation methods and devices for the past few years [1]-[2]. They fabricated the nano–structured Ni and Pd surface using plasma discharge and then D2 gas (0~300 Pa) was subjected to the nano–structured Ni and Pd at 200℃. They observed excess heat several times. For example, they observed about 78W excess power that is almost the same as input power. A similar experimental setup based on the Mizuno’s work was introduced in our lab in order to confirm the existence of the declared anomalous heat effects and to reveal the nature of the effects. Here, we report on the replication experiments at Tohoku University.

At first, temperature measurements were performed using a non-fabricated Pd wire with 7W and 40W heater input powers under few Pa and 250 Pa as blank runs. The temperature was measured by a thermocouple built in a heater rounded by the non-fabricated Pd wire. We fabricated nano-structured material composed of Pd and Ni by glow discharge on the heater located in the center of a vacuum chamber. And then, the nano-structured Pd/Ni was filled with D2 or H2 gas (~250Pa) for more than 10 hours. After the nano-structured Pd/Ni material absorbed D2 or H2, electrical power was applied to the heater covered with nano-structured Pd/Ni while evacuating the chamber, and observed the heater temperature behavior. Excess heat was estimated by comparing the heater temperatures for the nanostructured and blank experiments. Next, we introduced D2 or H2 gas about 250Pa to the chamber while keeping the heater input. And then, temperature measurement was performed and the excess heat was estimated.

For all the cases except for an insufficient nano-structured Pd/Ni case, significant temperature increases compared to the blank experiments were observed. In particular, in experiments with 7 W input, we observed 123℃ heater temperature increase compared to the blank experiment. It would be possible to say that we successfully replicated Mizuno’s work.

Since the heater was covered with nano-structured material, there was a concern that emissivity change affected heater temperature measurement. Numerical calculation was conducted to estimate the effect of the change of the surface emissivity. It is concluded that even if the emissivity would drop extremely from 0.7 to 0.3 due to the coating of the nano-structured Pd/Ni, the temperature rise would be only 70℃ at the most. The postulated emissivity change cannot be explain the observed temperature increase 123℃.

These experimental and numerical results strongly suggest that anomalous excess heat was generated by the interaction between nano-structured Pd/Ni surface and D2 or H2 gas.

I am in contact with them, and yes, they are in an early phase. They want to wait to communicate in this situation.
