Welcome

The Martin Fleischmann Memorial Project is a group dedicated to researching Low Energy Nuclear Reactions (often referred to as LENR) while sharing all procedures, data, and results openly online. We rely on comments from online contributors to aid us in developing our experiments and contemplating the results. We invite everyone to participate in our discussions, which take place in the comments of our experiment posts. These links can be seen along the right-hand side of this page. Please browse around and give us your feedback. We look forward to seeing you around Quantum Heat.

Join us and become part of the project. Become one of the active commenters, who question our work and suggest next steps.

Or, if you are an experimenter, talk to us about becoming an affiliated lab and doing your work in a Live Open Science manner.

We've hesitated to blog some the progressing research at HUG.

Because blogging each of these updates separately would only add to the confusion, we decided to fit it into a mega blog that features a wider range of we're up to at the moment. That way we won't cloud the Celani replication with all the side project updates, yet we may still inform you of what's keeping us so busy. It's a tough job! 

So I'm sorry for the length of this blog and for those who want quick and dirty updates. Hunker down with some refreshments at hand; I promise this one's worth the read. 

All the thanks to Kapytanhook 

Though we haven't talked about the LENRCAM story in a while, we have not left it in the dust. I have been unable to keep up with how much it has progressed. Most the changes have been in software, and we needed approval from the author before we unveiled anything. 

Here's a glimpse of how far we've gone. The image above is the BRILLIANT software given to us from follower Kapytanhook. He is developing the video processing software to look at hot objects and gauge their temperature with their emitted IR. Since our initial correspondence, we have gone through 4 beta trials that include image capture, color coding, temperature span and offset scaling, frame cancellation, noise indicators, and cursor-indicated pixel temperature. 

We fashioned a black box theater to test all the developments in the software. We decided darkness was the best visible light filter. 

Not only is the software cool, but accurate too! We tested the validity of webcam thermal indicators with a thermocouple lashed to the soldering iron. The webcam, thermal camera, and thermocouple varied from each other by only 2°C.

We've been very satisfied with the results, and will turn our attention to a reactor that features this technology in the future (Time is always in short supply).

Thank you so much, Kapytanhook for your prompt response and positive collaboration! Cooperation like this is a rare thing and the project would not be anywhere near as advanced without your support. This is exactly what live open science is all about!

Updates in Concentric Tube Calorimetry

The water jacket CTC is finally here! Though the road has been an arduous one, we finally have a working water flow concentric tube calorimeter. Below is a briefing on the changes made with the newest addition to our calorimetry research. 

Wayne's been busy updating documentation on the water jacket concept. 

The whole body shot. The thin wall reactor highlighted in our previous blog entry is shown inserted into the calorimeter. 

Here is the homemade water well with a heat sink and fan attached. Water has much higher thermal mass than air. The water flows over the heater  tube above room temperature (~40C at the moment). It's circulation passes inside this unit for control of the water temperature, monitored by the external thermocouple in black. 

Not to worry! The hallmark, cool flashing blue and red LED combo is still an integral part of the body. It really is a smooth and quick way to see what process the calorimeter is performing - heating or idle cooling. However closer speculation reveals the circuit board the LEDs are attached to. Paul designed a compatible circuit board that runs the length of the body just below the outer concentric tube but still inside the clear housing tube. It is SO much tougher and more reliable.

We laugh in the face of danger, running our water flow right past the sensitive HUGnet board. What we see here is the largest delay in the water jacket CTC commissioning. Paul had a heck of a time making sure the outer concentric tube was liquid sealed. We did not accomplish this on the first, or the second, but fourth attempt. It all came down to the wire port. Keeping this small area water tight was a pesky job! Each failed attempt at sealing meant another 48-72 hours of curing only after we applied the next coat of epoxy, not to mention drying the outer tube of the leaked water. Rest assured: we wouldn't pull  this stunt unless we were POSITIVE it was fail safe. So far so good. . .(We need an emoticon for crossed fingers for good luck.)

It's also pretty nifty how well the HUGnet board plugs into the integrated circuit board, eliminating virtually all the wires.

The small, bright yellow cord at the top is the separating line to force water flow along the length of the heater tube and back. The heater tube is the same RTD sense wire and heater wire wrapping from the previous design, however the wrapping is sealed with a 50/50 (v/v) mix of acetone and epoxy. Each coat was cured overnight on the same rotiserrie box we used to wrap the wires.

The active insulation piece of the assembly remains largely unchanged. However we soon hope to change the control algorithm used by the active insulation. Just today Paul introduced his idea to add a new self-adjusting control algorithm that is responsive to the ever-changing environment we put our cells through (it's a constant shuffle of reactors from place to place, in case you haven't noticed). This new algorithm promises to be much easier to use than a PID. More to come!

Idle but not forgotten, the air flow CTC rests just behind its younger sibling. These two photos are just to compare the relative size of the new hardware on the block. 

With a cradle for the reactor and active insulation, we're sure to have more stable results out of the new design. But the old version has not been obsoleted! We STILL await new pressure transducers to assemble a celani wire thin wall reactor to fit calorimeters in this new smaller format.

Sorry! No updates on the old CTC or powder experiments this time around.

 

Tired of these megablogs? We're hoping to soon drop a blog outlining our plans for a new website satellite to quantumheat.org. But it isn't your run-of-the-mill blog post; we're presenting it with slightly more formal attire and even proper grammer - so it takes a little longer to get it dressed up to go out. Please be patient! 

 

As always thanks for reading!

Looks impressive. However, you speak of "water flow concentric tube calorimeter". Does this actually means that you will use water as the fluid? As I understand it your working temperature for the Celani-wire is well above 100 degrees C. I would go for another fluid with the boiling temperature well above the Celani-wire temperature (somewhere on this site I've raised the similar question and got a suggestion for such a fluid). In this way you could control the aimbinent temperature to nearly match the working temperature. Then you would only need a few watts of input to the wire to raise the wire to the correct temperature. This would lead to a much higher output/input ratio. In essence, you would leave the few % excess power range and thus also the calibration error range.

Very impressive work, keep it up.

@ Andreas

We actually have not done any calibrations with the Water jacket CTC. We are tuning the PID controller right now and actually developing a different type of controller that we may implement before long. Once we have a few calibrations we can get this information out.

Been trying to pimp your company to the MN politicians - my read is that they are waiting until LENR emerges (hopefully Leonardo this April) before getting out in front of it. Your rep is outstanding, so it is the too-good-to-be- true LENR that is the disconnect. Good luck! 8)

The 100 mW is for the air jacket CTC, not the water jacket CTC.

@Andreas
Our error analysis shows a 100 mW resolution, but we believe more calibration trials and better insulation around the active insulator and sensors may increase this margin even further. We'll be sure to post this data when we start CTC active wire runs.

How accurate is the CTC? Did we get the 10 milliwatt accuracy Paul hoped for?

@Ecco

Mathieu has this week been tutored by one of the foremost scientists working with cutting edge flow calorimetry and they came up with a very good design using latest techniques. In time, when the critical replication of Celani's type cell work is advanced, and with resources, Mathieu is keen to develop this cell, but the project remains focussed.

@ Edwin

There is an outline of the wire treatment process in this paper.

@Paul Hunt: I stand corrected then. For some reason I assumed this was a simplified water mass flow calorimetry setup. I still think that would solve most of your problems/provid e more definite answers about actual heat production, but it has to be properly arranged (no transparent tubes, some basic insulation, etc).

@ Ecco,
This is not a flow calorimeter. The water jacket is to keep the outer shell at a very consistent temperature.
The electronics are mostly easy to access because the outermost tube is just a housing. The entire assembly slides out of it.

@ Edwin Pell
I agree, there are more ways for open air calorimetry to fool us than I initially could have dreamed possible.
No IR makes it through the water because the cell under test is inside a copper tube, that is inside another copper tube. The temperature difference between them is proportional to the heat in the cell.

The new concentric tube reactor looks cool (BTW, water flow calorimetry was pretty much needed, I think making that sooner would have saved you much time and money), but now that I get to get a close look at it, I ask you: are you certain that functionality hasn't lost a battle against looks? For example, I would have kept the electronics outside the tube, safe from possible water/gas leaks, explosion risks, heat and possibly low energy ionizing radiation.

Ease of maintenance (for example to replace wires in case of damage, etc) could also be a possible issue here, although I can't say this for sure at this stage.

How are the Celani wires made? Is there a paper by Celani?

What fraction of IR makes it through the water? Is it worth painting the inner cylinder black?

I am glad you are doing calorimetry where heat in and heat out are measured. I am doing temperature versus a base line and have found out how many way that can be misleading. Out versus in is the only way to really know what is happening.
