Celani Cell#2 about to restart

Written by Mathieu Valat on .

Most of the necessary part to build back Cell#2 alias EU Cell are here. As Ryan published earlier, I had to change all the internal parts of the cell and restart form clean new. I had to change the tube and the flanges anyway!

Almost the entire new design is glue free. I only need one ceramic glue spot to maintain the assembly together. The use of a reduced thickness mica (1.5mm) will increase the surface of "regeneration" of the active wire in case we need to do it. Because it will less act as a heat sink, conducting thermal energy through the mica.

By the way, this "regeneration" process consist in increasing rapidly the temperature of the wire during a short time under atmospheric condition in order to oxidize the copper that travelled on the surface and make it bubbly. This help to let the hydrogen absorption recover and brake the insulation layer of copper created after intensive heating.

Aside of this, I was pretty disappointed by the quality of the work made by my scientific glassblower that made the preparation of the tube. I wanted to use exactly the same tube as Celani is using. He strongly suggested to do it, because the brand is known to be stronger under pressure and temperature conditions and it thermalises infrareds just right.

As you can see the edges of the tube is too rought to maintain a good pressure/vacuum. The surface must have a better polish.

 

ETA of Cell#2 is estimated around Tuesday 27th. First Calibrations should be pubished by next Thursday.

Thank you to all involved. As a fascinated bystander, I am grateful that you are sharing your work on the net, and I truly believe you are modeling the future of citizen-based science.

Thank you for your kind answer. I will be very pleased to see the device running just in front of me.

I'll recontact you in mid december. Moving to Switzerland is not a problem for me as I work in Lausanne.

@Remi

Mid December, the European cell will move to Switzerland, just across the lake from Evian.
I propose you to come and visit at that time.

Am I right in saying the running of the Celani2 cell will closely follow Celani's own tests?

Congratulations for the great job you're currently doing. By the way would it be possible to visit your installation ? I am located in Evian.

Thank you !

Thank you Ged! I miss this warm occasion to share with beloved people.

@Ecco: Yes there will be!

@David: We already had an issue with this previously, so I tend to say it is not likely as you woud expect.

The ends if the tube need to be flamed to obtain a good seal

This should be standard practice for a scientific glass blower - if your glass-blower does not know how to do this I suggest you find another

Will there be realtime data for the EU cell?

By the way guys, happy thanksgiving! Even you EU folks ;). I think I can speak for everyone when I say, we are very thankful for the work you're putting into this, and the transparency, the methodology, and your willingness to explore this largely unknown field.

Looking forward to seeing how this new glass performs compared to the quartz. Quite an adventure!

I talked with my glassblower, I had to order two new tubes in order to be ready as soon as possible.
