Weird hybrid of a thermal concentrating foam, an IR transparent selective absorber cover, and clear bubble wrap cover to prevent heat leakage above the cover.

NC State News :: NC State News and Information » New Metallic Bubble Wrap Offers Big Benefits Over Other Protective Materials
Basically a very specific variant of metal foams (using large single bubbles), you can make stiff structures without a bulk material, and the bubble aspect is more controllable rather than a normal bulk foamed structure.

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.
