Other Progress - Updated w/ Video

on .

Our USA team has spent a great deal of our time last week supporting Mathieu's tests with the Euro Cell last week.  In between configuring, graphing, and writing, we have managed to make progress in other areas.

We have a new borosilicate cell assembled.  This is Pyrex brand borosilicate, which is still different from the Duran-Schott tubing used by Celani and by Mathieu in the Euro Cell.  This new cell is using Macor ceramic for the wire supports.  Both wires are NiCr.

We did a pressure sweep with hydrogen from 8 bar to 1 bar and graphed the indicating temperatures again. This is to continue to exploring the apparent change of temperature we observed in our first cell.

For the next test, we added some mineral wool insulation on each end of the cell to cut off most of the heat path to the flanges.  We expect this will make the T_GlassOut more constant over pressure.

The insulation is held in place by a wrap of copper wire.  We did a run over the weekend, but we are re-running it today because the power ended up at 47 W instead of 48 W.  Keep watching.

This has a new electrical pass through design.  We detected a leak with one of them and then fortified it again.  It is testing now and appears to be our tightest cell, yet.  It was losing 0.003 Bar per hour at 4 Bar (absolute) internal pressure.  Here you can see the long pass-throughs.  The length should keep the seal from seeing high temperatures and allows for several sealing layers within it.  

 

The Air Flow Calorimeter has been wired, instrumented and is just starting to be characterized for thermal stability.  Here are a few pictures.  

 

After we get comfortable that we are measuring and controlling correctly, the next step with that calorimeter is to test it with a control load and see what we measure.  We will definitely share that data as soon as we have it.

Anybody wanna volunteer to come play in the shop and help build other calorimeters and apparatus?  We have the inclination, but we need more man power.  Qualified volunteers will get free lodging, lunches, and a really cool prototyping shop to help manifest their ideas into reality.  To qualify, you need really strong shop skills, mechanical design and CAD skills, and an ability to tolerate Minnesota in the winter.

 

Update:  The Euro Team was on the Smart Scarecrow Alternative Energy Hour show.  Here is the video (link to youtube)

Quoting charlie tapp:
can you try the loaded wire in a vacuum after all it already has the hydrogen in it why does it have to be heated in a hydrogen environment no more hydrogen can get in the wire? worth a try


We are currently deloading the wire with 1A of current and vacuuming the cell at the same time. It is recovering the original resistance slowly, very very slowly in fact...

I don't think that we will recover the original resistance for multiple reason, if there is some hydrogen left inside and if cracks have been made during the process, this might have influenced this parameter forever.
Hydrogen is very hard to extract completely from metal because the hydride form is more stable at low loading ratio.

Concerning rock crushing and Carpieri, I continue to be sceptical. At least the idea that so much LENR would have occurred in Earth's crust that it would have altered the elemental composition in a big way appears to be contradicted by the fact that the energy liberated in such widespread nuclear reactions would have caused many orders of magnitude more heat release than the observed geothermal heat flux. Indeed, the sun is nuclear powered, but the earth is clearly not, the geothermal heat flux is only 0.1 W/m2. The idea might be tenable only if somehow endothermal and exothermal LENRs would for some reason closely balance each other, but no one has proposed that kind of mechanisms. There are some Japanese results of endothermal LENRs (nickel-deuteri um), but they have not been repeated as far as I know.

The data you published for the power input steps allowed me to obtain the curve of Power Output versus Temperature. The data was a excellent match to a second order function as before.

I then used this new function to run within my time domain model and obtained the following preliminary values:

Device Time Constant =454 Seconds
Energy Stored = 22.5 kilo joules @ Power input of 51.65 watts and 121.8 Degrees C at T_GlassOut.

These figures were for the latest stepped power input run for the US cell.

The performance of this new arrangement is not far removed from the earlier device.

@Andreas Van Rooijen

Yes - it is new research and its consequences are very far reaching. We are looking to do a Live Open Science with the researchers to show the LENR live from Quantumheat.org.

You can see it here.

How well does the mineral wool prevent heat from eventually escaping to the end caps? If it acts as a baffle that just slows down the path then we may not like how it muddies the temperature data.

I have my fingers crossed that it does not result in a small continuous drain of heat energy that makes it look like excess heat is leaving the cell for an extended period of time. The heat drain will eventually become a minimum once the end caps reach their steady state value.

This design may add another complication to the measurement accuracy and time domain response. Keep your eyes open and watch for this effect.

@Rob
I just watched the show. You were referring to an experiment with crushed rocks. Do you have a link for the results of that experiment?

By the way, the US cell is looking remarkably good. Those pressure and ambient temperature values are sumptuously stable.

My appetite is whetted for some experiments with this improved beast.

Part 2/2
It's important to make clear at the beginning of a conversation, what they did 23 Jears ago and what has changed and we know it today better. You don't need to write the history out of your brain, you can copy this part from others, maybe not word by word^^ A very good source is the presentation from the US Navy (SPAWAR)
at 2009. Strip down, and you have a perfect introduction
