S&G Cells: Preliminary Test Findings for Run 2 [UPDATE#4 - Exaggerated cool down graph]

on .

The first test run of the Steel and Glass cell suggested that it took approximately 6% more power to maintain the same volume of water at the same temperature in the control cell when compared to the active cell.

New Experiment Improvements

So, spurred on by the seemingly positive preliminary run of the Steel and Glass cells and taking a plethora of advice from the crowd, Nicolas sought to make some improvements to the experiment. The biggest revelation came from Celani, who informed us that the teens class wires (14 & 16L) that we used in the first run were actually the worst capability wires, this was explained in the previous blog post. So for this run, a new 14L wire was joined by a 360L wire.

You can see in the following images there were several improvements made to the experiment, many suggested by our followers. Chief of which was that the water containers were partially insulated with styrofoam boards.


Figure 1. Overview of the apparatus

Also, water stirrers were added and mounted in the same position and angle, pushing hot surface water down and creating a vortex.
Figure 2. View of stirrer blades set at angle in water and the driving motor mounted outside.

Water thermocouples were mounted on floaters to measure the water temperature at the same height from the water top level. This was ultimately found to be unnecessary, since the water temperature was very homogenous due to the action of the stirrers. In fact, the variation between bottom and top was only ­±0.1°C.

In the image below, the laptop on the left is running HugNetLab for data capture. The PSU with the blue display underneath is powering the water stirrers (2x DC motors in series), whilst the Dell laptop on the right is managing the duty cycle for them.

The 2 TTi dual channels PSUs are powering the 4 wires.

  • The top PSU is for Cell#2 (active)
  • The bottom PSU is for Cell#1 (passive)

The Second Run

The second experiment was set up and run between 9 and 25 May 2013, the logbook of which is here

https://docs.google.com/spreadsheet/pub?key=0Au5C1oywPfSKdGhxM1F6ZGNwSmxOZUh3bEZyMmRMMHc&output=html

Unfortunately, whilst the data was recorded on a laptop, it was not able to be uploaded to the MFMP’s data repository due to what turned out to be a failed hard drive and a problematic software upgrade process. Until the data is available on-line however (which should be very soon), it is contained below in some spreadsheets for you to work through.

Here is the data for the wire loading in Cell#2 and the runs for both cells (11 days).

Experiment Configuration

For each cell

  • 1 TC inside the glass tube for T_mica
  • 3 TC in the middle chamber for T_glassout1, T_glassout2, T_glassout3

Cell#1:

  • 2 Nichrome wires
  • Hydrogen pressure: 2.054 bars @38.5°C inside the glass tube
  • Helium pressure: 127 mbars @ 35.0°C inside middle chamber
  • Input power: varies from 60W to 70W (30W to 35W in each wire)

Cell#2:

  • Blue channel: 360L constant wire
  • Red channel: 14L constant wire
  • Hydrogen pressure: 2.054 bars @38.5°C inside the glass tube
  • Helium pressure: 127 mbars @ 35.0°C inside middle chamber
  • Input power: 60W (30W in each wire)

Preliminary Results for tentative discussion

Finding 1: Approximately 19% loading (0.81 R/R0)

Graph 1. Hydrogen loading related resistance changes over time.


Finding 2: There seems to be good evidence that more power is required to get the passive (control) cell to achieve the same water temperature as the active cell.

The graph below shows total input power for each of the cells (LHS) and the temperature of their corresponding water bath (RHS) over time. Cell 1 is the passive, cell 2 is the active. Annotations have been added to note events recorded in the log book. Note that the rate at which ambient affected the cells is relative to the water temp in the cells to begin with. Unfortunately, no ambient temp was recorded, but we feel there is some important information in the data anyhow.

For detail purposes, the graphs below show how resistance changes in the Celani wires required power to be adjusted to maintain an approximate 60W total in the active cell.

Preliminary Conclusion

We have an experiment design that is extremely easy to understand and that if the results hold up to scrutiny and are repeatable, we might have a suitable lab rat.


 

Further Work

In the next run, we will be using 2 X 400L class wires. We also intend to run for a longer period of time in order to get a more settled result. Ambient forcing and water level top up are problems seen in run 2, these are to be dealt with in the next test. The former by sitting the cells in chest freezers with the power off and the latter by sealing the tops of the containers.

We may later want to consider a mass flow variant of the outer shell which would allow accurate measurement as well as faster response times. Also, a larger inner cavity/more passthroughs would allow experiments on potential trigger and stimulation approaches.


UPDATE#1 - Last block of data available

As the data upload is taking so long, Nicolas has pulled the last block of data for this run from the laptop. To avoid you having to wait to see it, you can grab it from the link below, we'll try to find time to produce an annotated graph similar to graph 2 above.

Last block of data for run two

Please dig into the data and yes, we know that ambient would have been hugely useful here.


UPDATE#2 - Should we use a different heater?

So a few weeks back, whilst this run was underway, Celani phones us and says that he is stopping using NiChrome wires as "passive" wires  in his experiments because of their potential to exhibit excess heat.

This email address is being protected from spambots. You need JavaScript enabled to view it.&q=from:%22Jones+Beene%22" rel="nofollow">Whilst this should not be a problem for the Dual V2 protocol differential cells as there is no H2 in the passive cell under calibration or "active" run, it could be a factor in this experiment as the wires are in an H2 atmosphere.

One commenter called 'Jones Beene' on the Vortex forum alluded to this and suggested that we use some Kanthal resistance wire which is Iron-Chromium-Aluminium. This does not contain Nickel for certain, but it does contain Chromium, which according to Dr. Stoyan Sargs Basic Structures of Matter, Super Gravitational Theory's analysis, could be a very good candidate for the New Fire.

So, what to do. How about something radical. If the aim is to reach a steady state temperature in both water volumes, if we have them well sealed, stirred and well thermally insulated, how about just having a resistive heating element to heat the control water? Before you scream "different thermodynamics and time constants" well, that might just play to our advantage.

Think about it, it was difficult in the first two runs to match the active cell bath temperature because of the time constant being so long when making power adjustments to the passive cell. By the time the effect of the power adjustment had taken place the effect of ambient and potentially excess heat had made a moving target. Having a simple heating element would make the adjustments more immediate until the steady state of the overall systems were reached.

Ok, basically, maintain same power into active cell should achieve a target water bath temperature/rate of rise until steady state. Responsive adjustment to the heater element in the "passive cell" could allow rapid and responsive matching of its water bath. No LENR present in the heater element.

It has an added bonus of simplifying and reducing the cost of the experiment. Comments as ever below.


UPDATE#3 - New graph from second data tranche

Ok, so one of our followers produced a graph from the second tranche of data pulled from the laptop the other day, this is when things got closer to steady state and shows the importance of running an experiment like this for some time, here is what it looks like.

Active cell - input power RED (LHS), water bath temperature YELLOW (RHS)

Passive cell - input power BLUE (LHS), water bath temperature GREEN (RHS)

Graph 5. Fine adjustments of control cell input power to attempt to make its water bath reach active cells water bath temperature.

As ever, comments please!


UPDATE#4 - Exaggerated cool down graph

So it appears all of the data from the laptop is now uploaded to the online repository for people to explore in detail. It is interesting to note that data is recorded on the data logging laptops even if it cannot be pushed to the data repository, this proved very important given the failure of the harddrive in the array.

Below you can see the available data before the experiment was stopped of the cool down from steady state seen in Graph 5. The zoom in is further exaggerated because of the baseline being at 30, if it was 0, it would be very hard to distinguish any separation. There is however an extremely minor separation of much less than 1% over the 8 hour period. This indicates however that any thermal loss difference between the cells in the 3+ days of steady state in graph 5 when the control required 8.3 - 10% more power is not material to the indicative preliminary findings of this experiment.

Note: Ambient is actually the water bath temperatures on the data repository
