- Discussion of ultra-high-pressure (170 GPa) requirements for current room-temperature superconductors, contrasted with steel’s 250 MPa tensile strength, highlighting the impracticality of such containment.  
- Proposed alternative: graphene or graphite dispersed in oil, noted to exhibit Meissner effect as a surface rather than bulk property, with limited quench current but potential for long-distance, high-voltage, low-current power transmission.  
- Concept of “superconducting litz wire” introduced—many parallel, widely spaced graphene conductors to reduce magnetic field and current per wire while mitigating corona losses.  
- MIT’s July 2021 discovery of “magic trilayer graphene” cited: three graphene layers with the middle layer twisted 1.56° relative to the outer layers, forming moiré structures that enable superconductivity and magnetism at low temperatures.  
- Participants explored stacking limits and performance scaling of magic-angle graphene layers, with one user generating moiré patterns at 54.7356° in Inkscape to visualize the effect.
