decent HTS tape, in 600m rolls. Up to 2.3T mag fields, so good for turbine generators and MRI, but not high end stuff like fusion

BNL Newsroom | Breakthrough Iron-based Superconductors Set New Performance Records
New high current/high magnetic field/high temperature superconductor that is iron based that beats the pants off of existing iron and cuperate superconductors. Demonstrated 1MA/cm2 critical current, 200KA/cm2 at 30T at 43K (not quite LN2 temps but close), and they think they can up the temperature by further tweaking the layering.

Room-Temperature Superconductivity in a Copper Oxide
Not in manufacturable quantities, but this might be the first room temperature superconductor? Somebody needs to confirm this...

Furukawa Electric acquires SuperPower Inc., U.S. manufacturer of 2G HTS wire | SuperPower
Will be interesting if Furukawa makes a big push into medical MRI magnets, based on the cost/benefit of LN2 versus LHe2 (since helium is getting scarce). Now if the Sea of Japan grid intertie proposed by Softbanks's CEO Son would choose HTS...

Compact High-Temperature Superconducting Cables Demonstrated at NIST
Interesting that they have gotten over some of the manufacturing issues, by picking a HTS with a slightly higher strain capability but using it as a tape wrapping a simple copper core. Since this uses an HTS tape, it is comparatively easy to manufacture. It also seems that by using a higher strain capable HTS, they can reduce the cross section of the HTS cable for a given amperage. Now the next trick is figuring out a core former that is hollow to allow coolant to run through it.

Sumitomo Electric Develops Superconductive Cable With 50% More Efficiency - Bloomberg
1G HTS cable amperage improvement. I suppose that's good, but it's still first generation type HTS. I guess they have to get their investment back on the 1G production line before committing to more 2G HTS cable production.
