This is the most promising result I have yet written about. I put it together into a google doc that is embedded here. As usual, please let us know if I missed anything.
Many thanks to Celani, the rest of the MFMP facilitators as well as the frequent followers, commentators, and ad-hoc contributors.
Video explanation of results:
We put together a real quick video explaining the results in the report. Enjoy.
- in the EU, Mathieu is super close to starting up a very similar test with his cells in differential mode.
- In the US, we will to heat up CuNi2 to get it to load, then watch for additional excess energy
- Perhaps try to drive flux by operating in a partial vacuum and allowing the hydrogen to flow out of the wire.
- Add some Hemholtz coils to put the whole thing in a magnetic field, per a suggestion from Dennis Letts based on his work in electrolytic systems. Below is a rendering of a coil holder intended to hold 100 wraps of 26 gauge copper wire.
After looking at the data from Ecco's test, it appeared to Malachi that most of the leak was in cell A, so he tightened the threaded rods a little bit in case the leak was in the silicone o-rings. It seems to have worked. The graph below shows the Mica temperature in cell B, the pressure, and the resistance of the fully loaded CuNi_1 wire. It's pretty cool how they all tracked so nicely. The pressure does not have a general downward slope!
Meanwhile, the CuNi_2 wire is starting to load a little more as we start to raise the current in it. It is nowhere near as rapid as previous loading where we went straight to full power, though. We're OK taking our time because Celani suggested loading them in 25 degree steps and waiting till the resistance settles. Our steps are a bit smaller because I am not sure what to expect while the other wire is still on.
Our Helmholtz coils are taking shape. We will test them in open air before we try to put them around the cells. We'll post a picture after get them wound up and powered up.
Second Update on 9/5: The value of motion detectors
Just after we upped power into the cell in our attempt to get the second wire to load cell B started going up to 7 degrees warmer than cell A. This coincided with a good rate of resistance drop, too. We got a little bit excited.
Then we realized that Wes had been in there working on the powder cells around that time. We started to winder if he was causing an airflow disturbance. When he came out, the temperature dropped. We sent him back in and the temperature rose. This is clear on the graph below including the motion sensor data.
This is good to be aware of. We have asked ourselves if this could possibly account for the good results. While we can't rule it out totally, we also can't imagine a way the airflow could have been that far out of balance for that long.
Update 9/6/2013 - Magnetic effects on Cell A?
We set a magnet on the side of the cells several days ago on Sept 3.
Today, I took it of of cell A to take a magnetic field reading with an app on my phone. I didn't want to disturb cell B. Then I put it back on in nearly the same location with the same magnetic pole up. The magnetic had probably cooled down during that time.
Shortly after that, the power to both cells was raised by 2 watts. Cell A rose very little from the previous temperature.
A bit later Malachi adjusted the location of the magnet very slightly (a few millimeters) to what he remembered was the location it had been in originally.
The resistances of the NiCr wires behaved very strangely. The temperature of the cell behaved very strangely. The graphs below show this.
So the magnet would have been cooler and cooled off the sensor and taken quite a while to come back to equilibrium. But why do the resistance act funny? Especially on the NiChrome wires?? What will this mean when we put the Helmholtz coils in place?
