A step nearer to understanding superconductivity

A step nearer to understanding superconductivity

$this->bbcode_second_pass_quote('', 'T')ransporting energy without any loss, travelling in magnetically levitated trains, carrying out medical imaging (MRI) with small-scale equipment: all these things could come true if we had superconducting materials that worked at room temperature.

Today, researchers at CNRS have taken another step forward on the road leading to this ultimate goal. They have revealed the metallic nature of a class of so-called critical high-temperature superconducting materials. This result, which was published in the 31 May 2007 issue of the journal Nature, has been eagerly awaited for 20 years. It paves the way to an understanding of this phenomenon and makes it possible to contemplate its complete theoretical description.

Superconductivity is a state of matter characterized by zero electrical resistance and impermeability to a magnetic field. For instance, it is already used in medical imaging (MRI devices), and could find spectacular applications in the transport and storage of electrical energy without loss, the development of transport systems based on magnetic levitation, wireless communication and even quantum computers.

Just because you can explain how something works in terms of Physics does not mean you can duplicate it cheaply and easily. Fusion for power production is just one example of this situation and I beleive room termperature superconductors are just as likely to drop in any day now and save the world.

Moved earth and heaven, that which we are, we are;
One equal temper of heroic hearts,
Made weak by time and fate, but strong in will
To strive, to seek, to find, and not to yield.

As painfully slow the progress in this field has been over the last fifty years, like, as you say Tanada, fusion, I do see a working superconducter arriving sooner than working a working fusion reactor for one important reason; universities and labs around the world can study and experiment with superconductivity using relatively cheap hardware whereas fusion research requires huge multi billion dollar reactors that can take upto decades to built.

Even though I don't see superconductivity around the corner, we can expect a huge uptick in funds invested into this research as superconductivity understanding and possibilities at ever higher temperatures will bring us closer to the eventual reward.

Mass-producing room-temperature superconducting wires would suceed in increasing electric energy efficiency by 100 or 200%, but let's not forget we would STILL need to get that energy somewhere the first place.
