This year has seen the discovery of three new types of superconductivity, expanding the understanding of how electrons can pair to create a frictionless flow of electricity. These superconductors are all two-dimensional materials, which can be manipulated by stacking and twisting to exhibit various behaviors. The findings challenge existing theories of superconductivity, particularly with one instance being described as an "extremely unusual form" that many believed impossible. The discoveries stem from advancements in materials science, allowing researchers to explore a wider range of atomic arrangements and their effects on electron behavior. Notably, the research indicates that superconductivity may arise from diverse mechanisms, similar to how different species of birds fly. The recent breakthroughs include superconductivity in transition metal dichalcogenides (TMDs) and a novel form in graphene, suggesting that the field is on the brink of a deeper understanding of superconductivity. The ability to create and test various two-dimensional materials rapidly has opened new avenues for research, potentially leading to practical applications like lossless power grids and advanced transportation systems.

This article describes a new research result as a new research result, not as "trillion dollar industry by 2027". That helps credibility.
So a 1m3 7T magnetic field would be about 20MJ or 7KWh. That doesn't sound like much, but collapse times could be microsec to generate GW of EM.
If you ever wonder why these products using graphene aren’t commercially viable, it is insanely difficult to work with and prepare. Imagine trying to make a sandwich that’s 5x5 microns in area and about 2-3nm thick. Graphene is essentially atomic tissue paper subject to all sorts of contamination and small scale effects.
I came across another technique discovered many years ago, where they used scotch tape to alter the physical configuration of the material to make it superconduct. At room temperature, I believe.
This all sounds very ground breaking to me, yet we don’t hear about any big co doing any work on them.
Could reaction permutation and property testing occur in a more automated fashion than is currently?
