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

am .

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


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


  • 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)


  • 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.

Diese E-Mail-Adresse ist vor Spambots geschützt! Zur Anzeige muss JavaScript eingeschaltet sein!&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

... PX= 6% if T1=T2; PX=0 if T1 = 1.06 * T2, etc. (Of course, this is true only if temperature vs power is linear.)
0 #90 Paul 2013-06-24 19:29
Rather than varying the control cell input power to match the active cell water temperature, how about adding water to the active cell while maintaining constant input power to both? Add 6% volume and measure the temperature differential. Just a thought...
0 #89 Paul 2013-06-24 19:24
Perhaps you can better control for changing room temperature by sealing the devices and submerging both in a single water bath. The common bath could be be maintained at a constant temperature by trickling in tap water, which should be stable on a seasonal scale. Six or so watts of excess power is unlikely to create cross-talk within the bath. (But 2 baths would make it bullet-proof.)

There is a limit to what can be done with insulation. For a give insulation we can use more passes of wire. Eight passes of wire can be operated at 1/8 the input power and give the same temperature drop as one pass at full power.
+1 #87 Edwin Pell 2013-06-14 07:20
Bob, if we have 10% excess heat we can have self sustaining. It just needs better thermal insulation. So that only 6 watts is needed to maintain the temperature.

Part of the beauty of the thin wire is the small surface area for cooling. With 0.2mm wire at 1meter we have 6cm^2 surface area. This would be the same as a 1cmx1cmx1cm cube of powder (not very much powder).

One easy way to decrease the input power needed would be to replace the water with motor oil and heat it to 200 degrees C.
0 #86 Robert Greenyer 2013-06-10 16:57

You are right on there. The idea is that we create derivative of this cell that is modular & flexible, allows powders and wire in the same unit as well as ways to stimulate or trigger it. So we would have high voltage and light guide passthroughs to allow arc/glow and laser discharge. Make the chamber length correct to allow for standing microwaves and have a mounting point for components inside the steel cell that could emit soft x-rays, microwaves etc.

Nano powder is difficult to control according to Defkalion as too much potential for thermal runaway - they got round this by using nano foam and triggering with glow discharge which not only heats but allows ionisation etc. Wire is too spread out for effective cross talk between hot-spots so in the "How many Celani wires can we fit in a tube" I propose in the comments that packing all but the monitor wires tightly together to maximize chances of thermal cross talk.

Also phonon resonance might play a role... once the right conditions are identified for sufficient thermal runaway, in a reactant geometry, duty cycle of stimulation or trigger will maximise COP.

The water bath apparatus is nice because I think it readily adapts to different reaction chambers down the road. The most obvious down the road step is to go from nano coated wire to nano powders.

Meanwhile what triggering experiments can be performed on the wire apparatus? plasma?

The one nagging question I still struggle with is why an apparently exothermic LENR reaction requires electrically generated heat to sustain itself. Is this because we have a coated wire substrate? ie. heat dissipation rate is too high for surface LENR reaction to be selfsustaining. or is the voltage gradient along the wire surface important?

Can't wait to see the data from your next runs.
+1 #84 Paul 2013-06-10 01:51
And now the major concern is making the test bullet proof. That's very encouraging!
+1 #83 Sanjeev 2013-06-09 22:35
Yes, this experiment was most promising so far and it just needs to be made bullet proof, just like Ecco said.
Slowly reaching there.
+1 #82 Robert Greenyer 2013-06-09 15:48

As said before, given the amount of active component in the cell, if it was chemical, it should yield about 5W for one hour - and, it would need to consume all the Hydrogen, the Hydrogen pressure does not drop to zero and it is doing the over 5W of extra work every hour for over 3 days in steady state.


I agree better experiment protocol seeking advice from those that would like to challenge it most. I think ideas like low viscosity high boiling point oil, forced cooling to ensure steady state and of course ambient and a switch at the end would go a long way. Also, packing a bit more active material in there to ensure a bigger signal to noise ratio would be good too. The next run will have more capable wires so we will see what that does, then we need to appeal to Celani for a good bunch to really make it toast!

I guess if this type of cell continues to show promise with just thermal triggering, a version that allows many other ways of getting it going will have good potential. This quick experiment - whilst still easy to pick holes in, does form a good basis for those who know better to guide. It is also far less fraught with challenges than the standard Celani type. More than all this, it is stupidly easy to understand.

Getting a derivation of this experiment out to a number of independent people running a proven protocol first, seeing if they see the same results and then letting them do what they like must settle the debate. When it is only Celani, STM and us seeing something - then fair play to those challenging the findings. If others, on the same terms and then on their own terms determine excess heat, then we can all start working on what enhances the effect.

I hope we can help that day come soon.
