Scientists Create Zero-Resistance Superconductor

[Guest]

In in April, Kamihara and others reported (http://www.nature.com/nature/journal/v453/n7193/abs/nature06972.html) achievement of superconductivity in an iron layered complex at 43 degrees K, (230 degrees below zero, Celsius) minus that is, at a temperature 39 degrees warmer than that reported in Tom's Hardware.

Actually, Ht super conductors would make a quantum leap of ALL things electric/electronic. Something that could operate in the room-temp to relatively hot temp (100 C & up) would be awesome...but 4 now it's just a fantasy.

-4 Celsius doesn't make sense.. although thats cold, i doubt its cold enough to really allow superconducting, yet anyway
its prolyl -269celsius, as you can see, he spelled out Celsius which gives less chance the author accidentally but a C for a K

Currently what they do for the superconducting magnets for the MRI machines is cool down first with nitrogen to a certain degree (can’t remember) then follow up with liquid helium for cost reasons (liquid helium is expensive) down to 4K. I think what this article is really showing is that they can make a superconductor without the use of copper. The cost of this wire is substantial already and makes the costs of the MRI machines go up very quickly in terms of every mm larger the id of the MRI machine is. I think that what this article is showing an alternative strain of wire that is not based off of copper but has the same application (4K) in terms of cooling. I engineer the heat exchangers for the MRI machines so am fairly privy to the processing and use of this product.

This technology will never be accepted as the high temperatures will contribute to global warming. Cya!

This deeply offends me on a personal level.

That someone could write an article about this that is just blantly igorant of any scientific understanding whatsover is disappointing. To spread this filth that some layman might find as being new research is equally atrocious.

The headline is the just the beginning of where this article gets messed up. Scientists discovered superconductivity in 1911. It is not a mystery anymore, and it does not need to be created. By definition, it is zero resistivity (and its non-Ohmic). However, as resistance is related to resistivity only by how much of the material you have (ie, a 6m copper wire has more resistance than a 1m copper wire, same gauge), it is effectively the same to say that zero resistivity is zero resistance.

Beyond this, we've all seen how horrificly the contents are written. Typos all over the place, and nonsensical psuedo-science babble obviously obtained from sci-fi (hey, you know that means Science FICTION, right? as in *NOT* real!).

I propose then, that TH remove this article pending editing. Failure to do that should be mitigated by the prompt firing of the author, and the replacement of said author with an intelligent human being.
