New Type of Superconductivity Spotted
sciencehabit writes with this excerpt from a story about research into an unusual form of superconductivity:"Superconductors, materials that carry electricity without resistance, can be divided into two broad groups depending on how they react to a magnetic field — or so physicists thought. New experiments show that one well-studied superconductor actually belongs to both groups at the same time. The advance may not immediately lead to new gadgets and applications, but it suggests that superconductivity, which has already netted four Nobel Prizes, may be an even richer phenomenon than previously thought."
The shade will heat up, then emit IR radiation, which is the light that causes that heat in the first place. All bodies radiate, how much depends on their temperature.
Not a sentence!
Temperature is the wrong problem to focus on. Liquid nitrogen is relatively inexpensive & easily handled. With a good insulation system, it costs very little to keep it liquid. The real problem is that despite lots of industry & government involvement, high temp superconductors are still expensive to manufacture & not easily turned into wires.
