New superconductor theory may revolutionize electrical engineering
Phys.org ^ | December 6, 2013 | Bill Steele

Posted on 12/08/2013 6:38:56 PM PST by Utilizer

High-temperature superconductors exhibit a frustratingly varied catalog of odd behavior, such as electrons that arrange themselves into stripes or refuse to arrange themselves symmetrically around atoms. Now two physicists propose that such behaviors – and superconductivity itself – can all be traced to a single starting point, and they explain why there are so many variations.

This theory might be a step toward new, higher-temperature superconductors that would revolutionize electrical engineering with more efficient motors and generators and lossless power transmission.

-snip-

Most subatomic particles have a tiny magnetic field – a property physicists call "spin" – and electrical resistance happens when the fields of electrons carrying current interact with those of surrounding atoms. Two electrons can join like two bar magnets, the north pole of one clamping to the south pole of the other, and this "Cooper pair" is magnetically neutral and can move without resistance. Lee and Davis propose that this "antiferromagnetic" interaction is the universal cause not only for superconductivity but also for all the observed intertwined ordering. They show how their "unified" theory can predict the phenomena observed in copper-based, iron-based and so-called "heavy fermion" materials.

If this is true, this can revolution quite a few industries overnight! I can think of several related applications that have the potential to change radically. Not just Power and Energy, Batteries and Hard Drives can also be greatly transformed.

Maybe Jeff Bezos isn't so crazy after all and very soon, we will have all our household items delivered to us personally by airborne drones.

Interesting.

I think science will be the solution to a lot of problems, NOT government. If there is anything worthwhile that the government should be spending money on is research, not handouts.

This month’s (kinda early in the month) revolutionary new technology that’ll turn the (flat earth?) world upside down.

(Then we hear crickets.)

They revolutionize it before I even learn the basics. Sheesh.

Depending how it’s done, government “research” is indistinguishable from handouts.

Interesting stuff here.....

Sometimes they don't pan out, sometimes they do.

My young pre-school grandchildren were watching a streaming movie on a wireless tablet a little while ago.

That was science fiction in 1990.

It will be interesting if they can redefine 'high temperature' to 'room temperature' instead of liquid nitrogen temps.

That's a good thing. You won't have to unlearn anything if you decide to look into it.

They are NOT talking about room-temperature superconductors.

Room-temp superconductors are the holy grail of electrical engineering. That’s what the unobtainium was that they were mining in the sci-fi film “Avatar”

These materials they are talking about are still at very low temperatures.

Those drones are not supposed to get close to the ground at any time.

People picture the thing swooping down and landing on the front walk..lol

With dogs and kids playing in the yard there would soon be fur and blood flying... and huge lawsuits emerging.

They are to let the package down on a cord and release it from the end....staying well away from the ground. If by some chance the ground does get too close the engines halt immediately and the rotors freeze. Also some sort of near-instant inflatable safety device will deploy to soften the falling gizmo... a drone air-bag of sorts.

It’s all still a few years off anyway.

Yup, I pictured playful cats waiting beneath the lowering packages..lol

I also recommended fisheye cameras digitally record every flight as evidence if anything went awry. Even so, I’d hate to be in charge of such a scheme.

Yes, but compare that to the discovery of aluminum so many years ago and how expensive it was at the time to refine it.

Untill some enterprising young genius came up with a way to refine the aluminum oxide he had to almost pure aluminum metal using a totally new electrical application to do so.

Times change, and faster and faster it seems.

Actually, on a semi-related thought; I have to smile when I remember the old saying: "Any sufficiently advanced technology is indistinguishable from magic."

He says on a device that allows him to communicate almost instantly to people all across the planet. For example on a bus in the Middle East.

I’d love to play with room temp superconductors.

I believe we will one day have them.

Imagine the powerful static magnetic fields you could create in a small coil! Similar to what an MRI machine does with its super cooled coil.

Self sustaining magnetic fields of several T and at room temp.

It’s already done so. Giant magnetoresistance is a spintronic effect.

Apparently you did not see the 60 Mins. piece on Bezos where he demoed the drone landing on customer’s front walk, leaving the package and zipping away.

I’m with you, and probably Amazon’s lawyers, landing could prove troublesome.

That was just a publicity demo...that’s not what they are planning on doing. Only an idiot would do it that way..lol

There is no need to approach the ground other than back at the warehouse.

I remember well when we used lead at liquid helium temperatures to achieve superconductivity. In the case I’m familiar with it was used to seal out external magnetic fields from affecting Masers working at liquid helium temperatures. These devices were capable of achieving Noise Temperatures of the order of 10 degrees Kelvin. Amazing stuff.

Nice to see the slow but steady progress towards room temperature superconductivity. Very slow. But still moving forward. It is a potentially revolutionary technology.

I have a steep driveway and the UPS truck stops in the road then the driver/delivery person jumps out and runs up to place my packages on the porch. If nothing else, the drone could allow a delivery vehicle to station itself centrally to several deliveries, then drone the packages to the exact locations. I see great potential with this. ... Isn’t it a shame that we humans are not better ‘regimented’ to live in neat rows on broad streets, in high towers to concentrate the dwelling spaces and free up the earth for resourtces/food production? (/sarcasm)

I think it won’t be long until it is unusual for a person to actually drive somewhere, shop, and then bring the goods home.

As I unloaded those fifteen bags of shredded rubber mulch from my mini-van last night, I might have taken comfort in that thought ... but not really, since ‘labor/exercise’ is what the body was designed to do.
