- Participants examined the physics of black-hole propulsion, noting that smaller black holes evaporate faster and emit more Hawking power, making mass-feeding a stability mechanism rather than a thrust source, and speculated that dense “strange matter” cores in asteroids could serve as superior fuel for such drives.  
- The continuous nature of Hawking radiation was contrasted with the external observer’s perception of infalling matter freezing at the event horizon, raising practical doubts about 1,000-year payback schemes for black-hole energy projects.  
- A long-term vision was sketched of converting asteroids into rotating, glass-enclosed habitats that could host more old-growth forest acreage than Earth ever possessed, while acknowledging the structural fragility of rubble-pile asteroids and the need for artificial magnetospheres.  
- Links to the dormant “Abundance: Journal of Post-Scarcity Studies” and an upcoming abundance conference were circulated, alongside criticism that solarpunk aesthetics amount to “crayon art nouveau” enforcing frugality rather than embracing true post-scarcity abundance.  
- Early-2000s mailing-list archaeology surfaced proto-cryptocurrencies including eCache, opencoin, Ripple’s original commit-block-chain design, Nick Szabo’s “bit gold,” Adam Back’s Hashcash, and Hal Finney’s RPOW, providing historical context for today’s crypto landscape.  
- A new “webcash” bearer-certificate scheme was demonstrated, with discussion focusing on using decentralized mining solely to avoid issuing a security under the Howey test, echoing earlier debates around e-gold and digital bearer certificates.  
- A DeepFunding proposal requesting $40 k for a “self-evolving” DAO was dissected as buzzword-heavy and lacking simulations or smart-contract code, highlighting broader skepticism toward speculative crypto-fundraising.  
- Cold-flow test footage of a pintle injector whose cone angle varies with oxidizer-to-fuel ratio was shared, illustrating complex annular-ring dynamics and representing an incremental step in open-source liquid rocket development.
