Super Conductivity achieved at 130° C/400 Kelvin

aaaaaactually 130 C is 403.15 K. just sayin

"Room temperature"

Was that necessary?

There will be some time before anyone can recreate this, since the sheer forming of the alloy is probably extremely difficult judging by the instructions in the website of how the material was made. Either way, do not forget that there are some amazing scientists like Nicola Tesla who were declared liars and madmen by their contemporaries out of jealousy, so I wouldn't be surprised if someone comes up with a fake reproduction of the experiment just to prove them wrong without actually trying to make it work.

 

 

 

If a backyard scientist says he can do it then I highly doubt it is going to be harder for a well resourced university to do it too.   Whilst what you are saying about discrediting is true and did happen in the past, in this day and age of data retention and communication coupled with the fact that we have significantly more higher educated people means that such "faked" research is typically kept out of respected universities and peer journals,  and essentially restricted to blogs, forums and lobby group homepages.  Nowadays credibility is at stake for any scientist who dares promote that which he knows is flawed or not true.  Just look at Andrew Wakefield.

[ErickS89]

wow thats amazing

soon we will have super efficient computers that dont need cooling!

 

Actually that was achieved in the 1980s and even for the most part of the 1990s, tdp has to come to a point where the cpu can say "bring it on!" 

I think we're a bit a ways from desktop PCs running with no colling "No fans, heatsinks, waterblocks, etc"   You can however run a PC passively which at this time is the closest thing to no cooling PCs.  The Macbook achieved it recently and yes a desktop can do it to, hell even the old PowerMacs were passive but had quite a bit of fans...

 

Maybe in 5-10 years we can do it more effectively.

by soon i mean within the next 50 years...

 

and computers that use superconductors would mean almost 0 energy lost to heat, so no need for cooling

this wasnt possible for a long time because superconductors needed to be at extremely low temperatures, but now we can make some progress

[Dabombinable]

From my understanding, for a superconductor to be useful in everyday use, it needs to work at temperatures from about -10^oC to +100^oC.

[AHaskin14]

Was that necessary?

yes

[Takata]

Even if you have a material that superconducts at "room temperature", I don't think that implies you'll be able to make computer chips out of it. Might see some use for power transmission, or in your computer's PSU, but I don't think it's going to reduce the amount of heat your CPU puts out, unless you can make transistors out of this material.

[swifty7]

yep!!  making billions of transistors out of superconducting material will achieve that.

TinAntimonyTelluriumBariumManganeseCopperOxideium(not really) or TATBMCO rearrange and you get BOLT CTO a really fast chief technology officer. 

 

Corrected..

[_MMM_]

It says "low volume fraction of the superconductive phase", which means there are regions within the material which are superconducting but as they are not connected throughout the chunk of material (which you can read from their graphs, otherwise they wouldn't measure any resistance below the critical temperature Tc), you can't use it for macroscopic superconductivity. You'd have to find a way to make the regions connect to have the material as a whole be a macroscopic superconductor. 

 

So, while the website seems legitimate: Sorry, no superconducting wires/chips for you today. 

[foxhound590]

now this is very interesting 

[The Crazed Child]

I can't complain about this, at least we're getting somewhere.

[werto165]

Corrected..

Some reason I thought lead was Sb, buts it's Pb.... anyway...  

[swifty7]

DAMN IT!!!  I really wanted a hover conversion made to my car next year......oh! well!!!!!

[The Last MeMe]

Someone mind explaining this for me?

[RatedBlam]

I know this isn't anyway important and it has been said before but 400 kelvin. Why.

It's so easy to convert Celsius to Kelvins. You just add 273,15.

Are you sure you read the title of the topic properly? If you think you have and are still wondering why there isn't a Celsius measurement, let me explain it to you: 130° C stands for 130 degrees Celsius, which roughly equals 400 degrees Kelvin. Both of these are in the title

[godsarmy]

if true this would be epic

And 130C isn't room temperature, as the post appears to say.

Regular conduction of electricity comes with losses, largely due to internal resistance of materials used (copper, etc). You can minimize some of those losses by adding insulation, but it's still fairly significant. The reason high voltage transmission lines transfer power at such a high voltage is to reduce resistance losses, which is proportional to current. (Electrical power = Voltage * Current, Power is constant, increase voltage, decrease current).

 

Superconductivity eliminates that resistance loss, but typically requires extremely low temperatures for it to occur, too low for it to be practical in consumer electronics. The proposed material is promising, but if the process of actually creating it is cumbersome, then it's not economically viable for consumer electronics. 

 

The ideal material would need to achieve superconductivity within ranges of around 20-100C (typical operating conditions for electronics, depending on application) and be easy to produce in mass quantities (and cheaply). Until both happens, we won't see the benefits of the science.

Even if this works, I can't be the only one thinking that it doesn't matter for any general use purposes as it uses Te, which is incredibly rare. As rare as Platinum, which is more rare than gold.

[Pyrolizard]

Correct me if I'm wrong, but I think their jargon means that the materials are superconductive at or below 130C?  That's the critical point/transition temperature, which seems to mean that they resist current above that.
