MIZUNO REPLICATION AND MATERIALS ONLY

Quote from magicsound

Did you ask Mizuno about the source of the Palladium he used?

No response. I will ask again.

Here is a new report from Zhang.

It seems like magicsound 's run was within 1 °C of calibration or so. However I get different calibration temperatures with my own calculations (not shown here).

Nothing unusual happened with temperatures in the latter part of the test at higher power steps, but I noticed that pressure would tend to decrease somewhat over time.

For more detailed graphs, full data is necessary.

Quote from JedRothwell

Here is a new report from Zhang.

Did the report also come with with data, photos and graphs like the previous one from the same author?

Besides that he is advancing his work with variations over Mizuno's experiments, the most significant observation appears to be that there is an excess heat pulse after applying vacuum for a brief period (minutes) and then admitting deuterium gas again at low pressure. This was also noted in the previous report.

The complete data files from MR2.3 are available at https://tinyurl.com/y76fwnfr

The calibration points I referenced were from Cal10 on 25 March, with 300 Pa of hydrogen initially in the cell. Those temps were about 1°C lower than the earlier calibrations with 1000 Pa.

After cooling, the cell pressure was 670 Pa, almost double the starting pressure. This may be related to the pressure event noted by can in msg #2018. It doesn't seem to be leakage, because it was unchanged overnight. I'll have a look with the RGA later today.

magicsound

Calibration 10 does not have a data point for the 0W power step. Adding one and using a 3rd degree polyfit instead of 2nd degrees brings some changes.

Left: no 0W step and 2nd deg polyfit; right: 18.5 °C @ 0W, 3rd deg polyfit.

can Excellent. I see you caught the starting pressure at 174 Pa after overnight soak. What do you think of the end pressure after cooling being so high?

magicsound

I can only speculate, but one possibility is that the observed absorption was actually adsorption into internal surfaces (gaps) in the material (at the interface between Ni and Pd) and the high temperatures or deeper unloading during this run closed off such gaps, decreasing the amount of H/D atoms that can be loaded. This would be more along Edmund Storms' ideas.

Another possibility could be that consecutive loading/unloading cycles with deuterium can cause a kind of "blockage" at the lattice level and so loading will get progressively slower. However, according to Cydonia's account of Ubaldo Mastromatteo's loading procedure posted earlier, this could mean that excess heat and/or anomalous radiation emissions may occur with a greater chance during the next run(s).

If it's the second scenario, attempting several loading/unloading cycles in quick succession—perhaps similarly to what Zhang is suggesting in his latest report—could possibly yield interesting results, but to avoid wasting deuterium perhaps this could be done by separately heating/cooling LiAlD4 in the system.

yes, to me R20, thin films or Pd onto Ni foam are the same tricks.

i asked Ubalto retired from STM Microelectronics at last ICCF to understand better how he made to find XH.

Alan Smith was here at the same table.

He tried first to make several loading/unloading under H2 with no XH. then he tried the same by D2 BUT WITH THE SAME SAMPLE.

Loading behavior was different between H2 vs D2.

After each H2 loading/unloading cycle , time to reach full filling was decreased but no XH seen.

Then he started to try an D2 loading after have left H2 pressure during the week end.

Next Monday he unloaded H2 to switch by first D2 cycle.

However decrease D2 pressure was harder, but after several cycles when he reached full loading, he saw results.

I'm not saying it's the miracle recipe but it would be worth a try.

it must be understood that D or H enters lattice by a zigzag path, in successive vibrations.

Also, it's consistent that D vs H inertia play a role.

AlainCo

Unfortunately the charts are tiny, possibly they come from another website?

They are supposed to show short-lasting heat pulses arising after applying a vacuum for 5 minutes and then admitting deuterium at about 500 Pa. The actual peak output/input ratio seems low given that input power is 250W (if I am interpreting the data correctly) but the effect is probably worth exploring if it's reproducible at will.

That's on my "try this" list, as soon as I can get a bottle of Deuterium. My current technique using the decomposition of LiAlD₄ is too slow to use in this way. Because the decomposition is not a reversible reaction, each cycle needs a fresh charge of the crystals placed in the ampoule, which will also contain enough air to possibly poison the reaction. A 10 liter lecture bottle of D₂ is around $300, affordable for me BUT it's a controlled substance and can't be purchased without a qualified institutional address.

magicsound

What about transferring some of the deuterium from the LiAlD4 onto a piece of Pd to form PdD? Wouldn't it be more manageable?

RobertBryant

From the graphs provided in the other website linked by AlainCo and the description of the tests, Zhang pulled a vacuum and admitted about the same amount of deuterium after each "heat pulse" test. So, the before-after gas pressure information in this case has limited usefulness.

Hi Alan,

Dennis Cravens has one of these. It is a small hydrogen generator which uses a Proton Exchange Membrane,

therefore the gas output is dry.

Instead of filling it with distilled water he fills it with Deuterium oxide.

With it, he can get 3 litres per hour of pure dry deuterium gas whenever he wants it.

It's not very expensive and circumvents the pressure bottle regulations.

All the best, Pete.

Alan, Here is a cheaper one. 65cc deuterium per minute.

Pete.

I have a Parker H2-500 generator. It needs a dryer cartridge and takes 1 liter of D2O to fill the tank, around $1k from Sigma. It would produce WAY more deuterium than I need.

A 10 liter lecture bottle is under $200 and would fill the cell around 300 times at .01 bar. It also takes minimal space and no start-up time or maintenance. So that's my plan, just need a qualified agent to order. Working on it...

Would filling the generator tank with inert spacer material reliably work towards using less D2O?
