Alternatively solenoid operated valves could be installed in the inner chamber if gas is not going to be flowing once the experiment is underway. Any heat generated by the solenoids would be dissipated during initial temperature equalization.
@Gunthar I would love to use LabVIEW, just don't have the $$ for the software. I saw some ways to incorporate arduino, I was using the trial version and exploring it. If they don't track IP adress , maybe I can just keep re-applying for the trail with new User IDs ;)
I am just kidding, I wouldn't do that.
You talked about the sun hitting the garage door and affecting the room temp.
So if you do not open and close that door then maybe cover the outside with a large sheet of plastic and tape edges.
Also you could cover the outside of it with the same insulation you made the chamber box out of.
Lot of hard work there Russ. Looking good.
Fun watching you walk in my footsteps. :)
If you have an LOI (Letter of Instruction) written up, I'd like to see it. The video provides a nice overview, but the details are crucial to all this hard work being accepted into the science community.
Some notes you may or may not be aware of:
- 1 Calibration routines need to be executed before and after each trial.
- 2 Raw data must be recorded for each sensor. When I say raw, I mean non-calibrated voltage or current loop data.
- 3 I highly recommend using signal conditioners on all inputs. Your DAC may have them already--check to be sure and add them if it does not.
- 4 I would use LabVIEW to do ALL of your data collection and control. Having separate hardware for your PID control may likely cause you grief down the road.
- 5 If you don't have it already, prepare your post-processing (data crunching) algorithms now before you ever start a real trial. Every single data point will REQUIRE a full chain of custody audit trail, so you will need to not only reduce the data down to a form suitable for the final report, but show EXACTLY every step you took in the process. This should all be fully documented in the LOI.
- 6 I'm not sure what sample intervals you are going to use, but I would go with a standard one-sample-per-second. Hard drives are cheap these days and the last thing you want to do is miss a crucial data point.
- 7 When doing such tight tolerance temperature measures, I have found it wise to ALWAYS keep the test chamber several degrees above ambient. The reason for this is you have no cooling control, so the closer the test chamber is to ambient, the more difficult it is to lock it to a fixed value. The chambers I worked on had both heating and cooling and the trick is to run them both with a large overlap. This gives you the ability to lock the temperature rock solid using a proportional heating system. You may be able to augment your setup with a cold water circulation system to give you this ability. Then you can run STP at 72 degrees.
- 8 Before you run a real trial, I would highly recommend picking some sort of top scale heat you expect to see from the actual LENR chamber and be sure your complete system can handle this reading. The last thing you want is to have a successful LENR reaction that off-scales your instrumentation.
There are probably dozens of tips I have forgotten over the years--my last go at this stuff was in '97. If anything else comes to mind, I'll post it in this thread.
Good luck Russ. I hope 2016 brings great progress to the table.
:thumbsup:
Good luck Russ
happy new year...
i also recomend you to use labview, you will be able to save all data in the form of graphs and tables... not easy but not impossible.... i use it here for the water project to monitor all i need..
good luck
It is looking fantastic and I am glad to see it advancing. I think I already suggested everything I could think of since I am a complete calorimetry rookie as well. I am using a water bath in my system but I am short on funds for the plumbing right now. Just need to be patient to set up a simple pump primer. I would love to acquire PID controller like you have going on, but I didn't ask Santa ;) I did a trial with LabView and its awesome, not compatible with arduino though, and I am the epitome of a garage experimenter as you know. I am glad you took the advice on the aluminum for thermal reflection, but I would listen to Alan in putting some thermal venting of roughly 2mm slits or break points on the edges. Its like voltage potential in a way, the potential difference increases on the points and edges in the form of vibration in sense. In high voltage one could consider it ionization, the same is true for most frequency bands of energetic momentum. The more you can eliminate those places, the more stable system you have without a sudden radical leakage/release. Just like on a heat-sink where there is many fins to create a large radiation of thermal energy. Knowing and coming to understand your auto ranging system, I don't think its too much of an issue, but it might help in configuring your thermal difference between your control and sample reactors. Again, I am learning far more from you than I could give any helpful advice, as I am a rookie at this stuff. From what I have researched and learned, there may still be naysayers unless the excess exceeds a ~10% range due to your air temp swings and your thermal capacitance composition of a known value. That being the greater LA area air on any given day ;) Anything under ~10% excess heat, while a novel phenomenon, is probably not very useful anyways until completely understood and utilized to its full potential anyways right?
The results aren't as important as what we all learn from this process. Regardless of what they may be, if its any consolation, I love you all the same ;)
It may take me a couple more months than I hoped for to get my setup running how I envision it, but that's the way it goes when you have piggy bank resources. Perhaps its just the creator telling me to slow down to ensure when I run full experiments, they are designed to create what it is we are all so desperately searching for. A way for energetic abundance on this beautiful sphere we call home.
Much love as always and I look forward to seeing the Pd holder D2 runs you have in store for us all. I am more partial to the classical fusion experiments rather than the Rossi work, as he has become more of a talking politician than a applied scientist. You are truly an inspiration to many my friend, and I am glad to share this time and space with you.
Congratulations on a nicely thought out set up.
The only thing that I found that made me uncomfortable is the gas line being split prior to the two chambers and then recombined after leaving them.
That means an assumption has to be made that the gas is flowing equally in each path and if the gas is shut off, that there is no gas circulating in the loop moving heat around.
I am assuming that the system will be vacuumed, gas admitted, and then the flow shut off for the duration of the experiment so that leaves the circulation as an issues since the pressure equalization will get equal volumes of gas in each test chamber.
The two exit lines could be brought all the way out of the apparatus with valves installed on each leg to prevent circulation. That would increase the heat paths out of the apparatus so the consequences of that would have to be evaluated to see if that makes sense. Alternatively solenoid operated valves could be installed in the inner chamber if gas is not going to be flowing once the experiment is underway. Any heat generated by the solenoids would be dissipated during initial temperature equalization.
Yes, good idea Tcarey. I'm sure they make latching solenoid valves (same as latching relays) that could be triggered with an impulse to force the valve open or closed. The tiny amount of heat emitted during valve position change would show-up on the sensors and provide positive feedback the valve had been activated. Basically a mark on the data logging stream. With some pre-trial tests, this additional heat could be exactly accounted for. Then all that would be needed is to have LabVIEW generate the pulse at the proper time and make it part of the programming protocol for the test sequence.
Looks amazing Russ!
You have went with a very interesting approach to conducting your research.
All in all I have to say I think it is truly excellent.
What type of lattice are you putting in your SS tube? (I guess you'll be sharing that in upcoming videos)
The heat differential method for calorimetry is interesting.
I really hope you achieve heat energy gains from the way you have your system setup as it would prove that no energy is needed to excite the Deuterium loaded lattice ... I will say I have a bit of a gut feeling that the LENR/Cold fusion phenomenon relies somewhat on
#1 : the deuterium (or hydrogen) loading process into the lattice
#2: and ALSO the excitation provided to the lattice by current running through it (<--I could be totally wrong <That is why we are trying to run these experiments I guess :D )
I am looking forward with enjoyment on your progress!
I am also looking forward to conducting my own LENR experimentation setup. (I have been learning C code as much as I can and I hope to be able to make my own simple program to run my calorimetric calculations)
We shall see.
Again, amazing work! Exciting stuff!
Peace :)

@Diadon
Ahhh, I see... The current is passing through the lattice then through the 10k resistor... Ahhhh..
Very nice.
For some reason I thought the setup had the 10k resistor in there to warm the chamber...
Super interesting and incredibly awesome setup.
Looking forward.
:D
1. yes good point to do it after the test also.
3. signal conditioners
5. can you please go in o more detail onthis, im not so sure i fully understand this. i think i do but before i respond further please elaborate for me!
7 i thought good and hard about cooling and heating at the same time. however when you have them you have to account for them. heating is much easier to account for. cooling requires a bunch of extra precise flow and delta calculations. and for this system i was not willing to play the cooling game. however i did decide to use the "above ambient" method. this is actialy a " second version" of my setup after i did some testing and decided to go this rough of heating. the next step is to put the entire system is a double walled vacuum chamber of some kind...
