After the coffee break, Jed Rothwell is speaking. The nickel-mesh is physically rubbed, and heat measured with the air-flow calorimeter.
He shows results from the previous conference, about 12Watts excess.
50 Watts input, 300 Watts output, 250 W excess, including losses (175 Watts excess without the losses). The R20 best result gives 11 degrees C temp jump.
July 18, 2019 reality check 216 W in, 324 W out, 108 W excess with the R21 reactor. Power, temperature and air flow rate measure independently. Jed says, this is a confirmation, a reality check. It is not a replication, but he considers this result the next best thing. Mizuno has redundant instruments (which all say the same thing). This corresponded to about 5 degrees temperature difference. R21 has the same geometry of the R20.
Several replications are underway. Ahang reports succes sieth a Seebeck calorimeter. Problem: reaction tapered off. Some people said the nickel rubbed off of the mesh, and the palladium didn't stick. Another person did not produced heat for a week or two, then, 4 W and 9W, and then higher (missed that).
Rothwell and Mizuno uploaded a detailed recipe, which he repeated. He says some details you don't need to know, like the detergent brand name, but who knows, so he included brand names. People were wondering about the washing in the tap water, like, what is in the tap water in Sapporo?
Mizuno has burnished nickel messh w/ Pd, and distributed them. That was just last month, so no experiments are going yet.
He will have his R20 nickel-mesh that produced big heat analyzed by ________(superglue lab???)_ .
This is more art than science, so if you've got ideas, they will take them.
Jed hopes that replicators will get 10 Watts, which is what Mizuno got at first last year.
They know that the flow is turbulent because they did a traverse test. Their results show uniformity at all points inside. Low heat means not much heat is lost through the walls, but how much? They measured heat recovery at different locations and nailed the numbers down. However, they can ignore the losses from the walls because the heat generation is so great, the wall losses are negligible.
Mizuno moved the heater to the middle of the inside of the reactor, and that seemed to improve performance. One mesh to the next gives different performance. R21 with new mesh only gave 30 Watts excess with a 102 W input and 135 Watts outpus. Heating in cycle 1.5 to 3 hours long. The sample is spontaneously heating and cooling and loading and de-loading - this is all not under Mizuno's control. But this tells him that flux is important.
The R20 data is so stable, Jed gets suspicious, thinking it is maybe an artifact. But the jiggly R21 data makes him more positive. Since all variables are measured independently , he feels the artifact explanation goes away.
He went through the points of Edmund Storms paper Relationship between the burnishing process used by Mizuno and the Storms theory of NAE formation and says that storms is able to explain the important aspects of this.
QUESTION ANSWERS Jed refers to details in the paper, which he doesn't have a copy of but is on the Internet.
The same mesh moved into a new centrally-heated reactor will work better.
The unit will work for months! He shows a graph over 111 days.
A lab in the US has one of his three (stacked) nickel mesh sheets for analysis and they will see if there are any other daughter products.
