Zr-Ni-Cu alloy performance Ames National Laboratory processed metal alloy foils via arc melting followed by melt spinning. This is the Yamaura process employed by Arata and others. The foils were baked in ordinary air at 445C for 28 hours. The brittle, oxidized foils were placed in a tumble mill for 24 hours. This resulted in 30 grams of black powder with a median grain size of about 40 microns.Presumably, each grain has about one million nanoscale islands of NiCu inside. The 30 grams occupies about 7 ml inside the 50 ml dewar. The system was vacuum baked at 220C for 24 hours and cooled to room temperature. H2 gas was added at 200psi. The pressure dropped only to about 185 psi over twenty minutes. In these replication experiments the exothermic reactions have had peak temperatures above 220C with substantial loading above 3.0 H/M ratios. This time the temperature only rose by 2 degrees C. The system was heated with a band heater to high temperature. There was no controller. A rheostat was set at an arbitrary position and the system comes to a an arbitrary temperature.The average power input was 90 watts. After several hours the hydrated system was evacuated overnight at a constant high temperature at 530C. The next day H2 gas was again added at 100psi and the temperature rose by 40C to 570C and came back down to 530C after two hours. At the end of the day the dewar was again evacuated while still at 530C overnight. The third day repeated the same procedure. H2 gas was added at 100psi and the temperature rose by 44C to 574C. However, this time it did not come back to the initial temperature. It remained at the elevated temperature overnight. On the fourth day H2 gas was again added at 100psi and the system rose by 50C to 580C and again stayed at the elevated temperature indefinitely. A rough calibration suggests that the 30 grams of hydrated nanopowder is putting out 5 watts of excess power. Yesterday Peter Gluck suggested that the relationship between loading and excess power may be a myth. This seemed to be true for electrolysis with Pd and heavy water where loading levels exceeding 0.9 D/M were a prerequisite for observing excess power. My loading level with this nanopowder sample as less than 0.1 H/M. This 5 watt excess is very much less than Rossi, but it is a real and repeatable experiment There was no radiation above the background level. Other alloys from Ames NL are expected within ten days.</ref> | Zr-Ni-Cu alloy performance Ames National Laboratory processed metal alloy foils via arc melting followed by melt spinning.
