For this reason, this field of research has always generated enormous interest, and considerable resources are utilised on techniques that can transform these materials into good energy conductors in technical components.
Today the industry preheats huge meter-long aluminium cylinders known as billets in induction heaters with copper conductors. When the temperature reaches 500 °C, the billet is extruded to profiles.
“This heating process leads to large losses in energy,” says Runde. “Only half the energy supplied is used to heat the billet. The remaining 50 percent is waste energy. This is something super conductors can improve.”World’s largest
In the basement laboratory, Magnusson and Runde proudly show the two large super conducting coils, with a 1.5m diameter. The super conducting material, magnesium diboride, is in thin, brittle filaments enclosed by a nickel matrix.
“These will be the world’s largest super conducting coils made from this special material,” says Runde.Generating interest
Magnusson and Runde have continued with the research in a parallel and competing race with Zenergy Power. In an EU project with eight other partners, SINTEF now has a model under construction that is expected to be cheaper than the German model. In this model, the Trondheim research scientists designed and built the super conducting coils.
“We have deliberately kept a low profile to see if Zenergy Power succeeded in building a complete model,” says Magnusson. “We now believe the time is right to mark that it is in fact a SINTEF invention behind the product.”
With around 500 extrusion lines in Europe, the super conductors will be a typical niche product. However, given that the industry stands to make energy savings of up to NOK 1 million for such induction heaters, the energy researchers believe there is a market for the product.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
