- Explored the idea of using the solar wind’s charged particles as a giant lens to focus solar radiation, but concluded the energy required would likely exceed any harvested gain.  
- Debunked the Bussard ramscoop concept: the drag from scooping interstellar hydrogen exceeds the thrust generated by fusing it, making net propulsion impossible.  
- Discussed the EmDrive and Woodward’s “MEGA drive” as fringe propulsion topics; participants agreed both lack experimental support and are generally considered dead ends.  
- Outlined a speculative path to RGB-tunable hair color via triple-gene constructs activated by distinct co-activators, noting that CRISPRing living human cells remains risky.  
- Argued that near-term “nanotech” will be biological: ML-designed proteins, ribosome-based nano-assemblers, and engineered enzymes already outperform hypothetical diamondoid machines.  
- Shared detailed personal experiment with low-dose selegiline (MAO-B inhibitor) for severe ADHD and depression, reporting improved executive function, mood, and libido with minimal side effects.  
- Warned that combining selegiline with phenylethylamine yields meth-like pharmacology and that selegiline’s irreversible MAO-B inhibition creates long-lasting receptor changes.  
- Proposed alternative, safer reversible MAO-B inhibitors such as the experimental compound ladostigil and even garlic-derived organosulfur compounds.  
- Presented a concept for cheap orbital access: use a sub-orbital rocket to 200 km altitude, then employ eddy-current braking on an orbital track to reach orbital velocity without chemical burn.  
- Linked two new cryptography papers: threshold ECDSA for decentralized custody and blockchain-based secret storage/retrieval schemes.
