- A debate over whether open, distributed manufacturing can match or exceed the quality assurance of profit-driven industry concluded with the claim that non-commercial products are often superior in practice.  
- The 1995 essay “Agalmics: The Marginalization of Scarcity” (http://www.openverse.com/~dtinker/agalmics.html) was introduced as a conceptual framework for post-scarcity economics beyond money-based exchange.  
- A student paper on a low-Earth-orbit atmospheric scoop to harvest O₂ and N₂ was critiqued; participants proposed turbomolecular-pump or charged-particle braking as superior alternatives to the paper’s propeller/balloon deceleration scheme.  
- Concern was raised that algal-biofuel researchers ignore the energy cost of liquid-nitrogen cell lysis, potentially rendering the process ecologically counter-productive without full energy accounting.  
- Transcranial magnetic stimulation hardware links (Brainsway, Neuronetics) and coil-optimization papers (Eaton 1992) were shared, along with the idea of field-programmable coil arrays to steer stimulation patterns inside the brain.  
- Fab-lab self-replication was highlighted: universities are not using fab-labs to manufacture their own stepper motors, circuit boards, and other components, missing the chance to bootstrap a fully self-contained tool chain.  
- Mindat.org mineral-deposit data (mindat.zip) was circulated to analyze whether a high-tech city like São Paulo could achieve material self-sufficiency without inter-regional trade.  
- VOICED (Virtual Organization for Innovative Conceptual Engineering Design), an NSF-funded ($82 k) multi-university reverse-engineering repository, was discussed; its data quality was judged poor and its interface is being rebuilt from a crude web form to an Ajax front-end.
