This material, a copper oxide, is like a thread that conducts 100 times more electricity than copper. With this thread you can for example make cables to transport much more electricity or generate much more intense magnetic fields than today," he [project coordinator] told AFP.

In superconductivity—first discovered in mercury in 1911—electrical resistance suddenly drops to zero in some metals when they are cooled to near absolute zero (-273 degrees Celsius, -459 Fahrenheit).

This also produces a strong magnetic field—an effect which has found applications, including in MRI body scanners.

To achieve zero-loss power transmission now, cables encased in tubes can be cooled with liquid nitrogen to make them superconductive—but the complex and expensive technology has not been commercially used on a large scale.

Phys.org, phys.org...]European team announces superconductivity breakthrough[/url].

GAH! There are no specific in this announcement! Like what variant of copper oxide cuprate was created? How high can the temperature be? Most super conductors have to be cooled to 4 °K (that is degrees Kelvin which starts measuring at absolute zero) with other high temperature superconductors only having to be cooled to 77 °K which is where liquid nitrogen is. This announcement has no specifics! Known cuprate REBCO (rare earth barium copper oxide) becomes superconductive at this temp too.

Besides not having specifics, efficient transmission of power is one of those items that is needed to have happen, in my opinion, before a nuclear fusion reactor can be turned on. The item is energy storage at the grid level.

Either way, this is good news for MRI machines. A high temperature superconductor is always welcome news. Even for magnetic coils in a nuclear fusion reactor. If this can manufactured in length, power distribution would benefit immensely.

If anybody hears anymore about this please provide some details as some of us here are detail oriented.

this is mega big news.

this will basically remove most the biggest challenges to conductivity, cooling and efficiency.

the only thing im questioning is the development of such synthetic alloy. maybe we should put "cheaper" in quotation marks until they process is reviewed.

Eurotapes is a four-year project involving world leaders in the field of superconductivity from nine European nations -- Austria, Belgium, Britain, France, Germany, Italy, Romania, Slovakia and Spain.

The European Union covers the bulk of its budget of 20 million euros ($21 million).

Yahoo! News, European team announces superconductivity breakthrough.

So there is a little bit more on this story. I hate these: "Here is a press release" type science stories because there is little to no change in any of the information.

Yeah, I hope this pans out. The trick always is to make something to scale up to industrial levels. I think I read that 10% of electricity is lost to heat in transmission. So if that can be made up then there would be less pollutants in the air which would do the world some good. Even if it is only used like from a wind farm to an electrical substation and storage that would be huge!

I don't think electrical distribution has changed much since Tesla's time! So a new method will always be news!

"This new material could be used to make more potent and lighter wind turbines," he added, predicting it will make it possible to manufacture wind turbines one day with double the potency than existing ones.

In the long run the project could "revolutionise the production of renewable energy," the Institute said in a statement.

This is from the Yahoo! source.

And this is the Phys.org source.

This is a prime example of press release science. Surprised it has not shown up on Eurekalert! yet.

The ability to carry high electrical current in the presence of a strong magnetic field is a key enabler for the superconducting applications of the future. Using a technique called pinning, superconducting wire performance is dramatically improved. The traditional approach is to add more elements when manufacturing the superconducting layer, thereby increasing the complexity of an already challenging process.

Quiram continued, “STI has demonstrated the ability to incorporate pinning into our superconductor without using additional elements..."

...

Rare Earth, Barium, Copper Oxide (ReBCO) materials are recognized as a superior superconductor by offering better performance in a magnetic field. STI’s RCE-CDR process grows a ReBCO superconductor film onto a flexible template. This process requires accurate temperature, uniform pressure, precise ratios of elements and the presence of oxidizing atmospheres to grow high performance superconducting materials. The company’s RCE-CDR system is scaled for large batch operation to insure every portion of superconducting wire has uniform material properties.

Globenewswire.com (press release), Feb. 16, 2017 - Superconductor Technologies Inc. Awarded U.S. Patent for Unique Manufacturing Process.

Seems like Eurotapes may have been playing catch up with STI. STI looks like they are out of Texas.

The above notes "pinning" which I read as adding more elements to the mix. Sometimes called a dopant, the idea is that the dopant adds to the superconductivity. But it can also interfere with the property. So if they can beef up REBCO without adding more to it then that is great! And it happens in the production of the REBCO tape itself which they already have at large scale production.

Looks like this might be a sort of arms race between high temperature superconducting tapes! STI vs. Eurotapes in a copper oxide showdown!

Arecibo was using liquid nitrogen in the 1960's IIRC so?

a reply to: Cauliflower

For power distribution?? Or was it to isolate equipment for the frequencies they were observing?

The new superconductor could be used for power distribution since it would not require cryonics of liquid helium (which is expensive). They even envision using it in wind farms because it uses liquid nitrogen. The expense of using liquid helium has companies like GE trying to reduce their MRI and NMI device because of that cost alone. The OP announcement goes a long way towards doing exactly that. But I am PO'd that there are no specifics in the announcement.

Smaller motors, smaller generators, maybe even something crazy like a superconducting flywheel for energy storage, are just a few other applications I can think of right off the top of my head.

Of course the real winner, if we are ever told about it, would be a room temperature superconductor but that will have to wait until one is realized.

That don't seem right. Not even sure what that is supposed to mean?

Right? It is on a science sight that will at least explain "1 astronomical unit is the mean distance between the earth and sun" in one of its other stories.

This one? They took the press release and posted it. There are no scientific terms in it. No measurements. And yes, that statement too. That does not help one understand what has been created!

Basically, a normal wire can only carry 1/100th of the amount of cooled superconductor wire. But like you said, so what? ALL superconductors do that! Why is this one special? How does it differ from other high temp superconductor wires or tapes? I had to guess that because of their "liquid nitrogen" blurb that their wire does not need to be cooled with liquid helium. But that is not revolutionary because it already exists.

So I will keep an eye out for what actually was created. I hope it is cool and can find other uses.

for now otherwise I'd be crying....

So the group is lead by the Institute of Material Sciences - Barcelona (CSIC)

I found their original press release, in English, but it is nearly word for word the same as Yahoo! and the Phys.org article.

What they did do was encase the wire in a tube that allows them to use liquid nitrogen to cool the tape to superconducting temperatures. They created 600 meters of it and ran some electricity tests.

The last blurb also mentions "room temperature superconductors" but it is not anything different than OP source.

More digging around tomorrow!

Yup, like Watt and Volt it is a measurement unit so "degree" is redundant. It is just "Kelvin"

My bad.

Eurotapes is a four and a half year project funded directly by the European Commission with 20 million euros. It’s an collaborative effort involving researchers from University of Cambridge, University of Antwerp, University Autonoma de Barcelona, Technical University of Cluj-Napoca, Ghent University, Vienna University of Technology, Institut de Ciencia de Materials de Barcelona, ENEA, IEE Slovak Academy of Sciences, Institut Néel CNRS, IFW, LEITAT, Bruker, Evico, Theva, Nexans, La Farga, Oxolutia, KIT and Deutsche Nanoschicht.


and


Moreover, Obradors and colleagues are also working on superconductive generators which are much lighter than conventional ones (only a third of the weight) and produce more electricity. Obradors says that if we’d replace conventional generators with superconductive ones, a single wind turbine could produce between two and three times more electricity.

ZMEscience.com - Superconductivity breakthrough could reset Europe’s power lines and make renewable energy more competitive.

A little more news. This article is a bit more speculative about the effects of swapping out power transmission lines and does some explaining on how the lines currently work. It also quotes from the press release so is not really a source of new information.

That is a pretty big consortium! I am glad to see that a lot of people are thinking about power lines in a different manner!


Right now, the record is held by cuprates, which have demonstrated superconductivity at atmospheric pressure at temperatures as high as 138 K (−135 °C), and 164 K (−109 °C) under high pressure.

That is nice info to know.

EUROTAPES project is coming to an end in February 2017 and the project consortium is meeting in Barcelona on the 13th-15th of this month to present their final results. After 54 months of research, the project will be closing as it has achieved its objectives. The Eurotapes project has managed to produce 600 meters of superconducting tape with a process that reduces the cost of production of superconducting materials, simplifies its architecture and improves its capacity in high magnetic fields through various temperature scales.

Eutotapes.eu, news - Final Meeting of EUROTAPES project in Barcelona.

And here is the tech, nerdy, but useful information that should have been in their PR article too!


Demonstration high critical currents (Ic over 400Amps /cm-w, at 77K and self-field and Ic over 1000A/cm-w at 5K and 15T) and pinning forces (Fp over 100GN/m3 at 60 K). The CSD and PLD technologies will be combined to achieve optimized tape architectures, nanostructures and processes to address a variety of HTS applications at self-field, high and ultrahigh magnetic fields.

Nextbigfuture.com, March 15, 2017 European superconducting tape achieves goals of lower cost and more efficient superconducting tape.

The project ended. That should have been the first thing mentioned in their PR article! Putting them together, my press release would look something like this:


Our project, Eurotapes, ended and we met our goals. At our final meeting, March 13-15 our findings were discussed at a gathering in Barcelona. 600 meters of low cost, high temperature superconductor power cable was created and tested through various temperature ranges. High magnet fields were also demonstrated at the same time.

A self-contained liquid nitrogen cooled copper oxide high temperature superconductor power cable was created and tested for load at high temperature (77 K) and at low temperature (5 K). Production quality was kept while lowering costs.

Applications of this research can be applied to creating increased magnetic field strength like those used at CERN and ITER/DEMO; power distribution; and generators like those used for wind farms where electric output could be doubled if the HT tape is used.


That is a press release! It tells you who, what, why this is news and worthy of attention! The statements are simple and to the point. I hope that makes sense to everybody because it does to me now! It has some numbers but not enough to detract from what was accomplished. Next I would name the world-wide teams that worked on this project:

In addition to the Universitat Autónoma de Barcelona, the ICMAB and LEITAT; The universities of Cambridge, Antwerp and Ghent, the Technological University of Vienna and six technology centers and 8 companies from Belgium, Austria, Romania, Germany, France, Slovakia and Italy.

Mystery solved! It only took 4 sites and a few days! LOL

Now what do think of this garbled, bassackwards, thread I created ATS??

So what is the new claim? The molecule in question is an aromatic hydrocarbon called teraterphynal... As a material it is used laser dyes and sunscreen, it is unremarkable.

[Researchers] at Hubei University in China say they have made it superconduct at 123 K by doping it with potassium

MIT Technologyreview.com, March 24, 2017 - High Temperature Superconductivity Claimed for Sunscreen Molecule.

That is a crazy accomplishment! (There is some bloc on the site so any and all typos are mine). There is more to it (more processing occurs rather than just doping it) and it is baked for a while under pressure. Then they put it in some capsules for safe keeping. But when they ran the temperature check, at -150 °C all resistance disappeared.

Even near room temperature will save money. Combined with the tapes-power distribution cable news... the idea is closer to realization as ever!
