- Feasibility of nuclear-electric rockets for Earth launch was questioned; participants concluded that low thrust-to-weight and atmospheric constraints make them unsuitable, favoring nuclear-thermal rockets or high-temperature superconducting/fusion concepts instead.  
- Discussion of orbital mechanics showed that a 1 N ion thruster could launch a 1000 kg satellite from a 3500 m-diameter, 2000 kg/m³ asteroid whose escape velocity is only 1.85 m/s—raising the half-serious idea that a human jump could initiate departure.  
- DIY solid-phase synthesis of spiroligomers and DNA via hacked inkjet printers was explored; key hurdles identified include handling corrosive deprotection reagents (95:5 trifluoroacetic acid/triisopropylsilane), inert-gas enclosures, and cartridge material compatibility.  
- POSaM (Parallel Oligonucleotide Synthesizer and Microarrayer)—an open-source inkjet DNA synthesizer—was referenced along with community build attempts that stalled on solvent-fume extraction and safety issues.  
- A 2013 paper on iodine-mediated neutral N-Boc deprotection was shared as a possible route to avoid strong acids in peptide synthesis, though solvent-free conditions may complicate inkjet implementation.  
- Wiki housekeeping notes revealed efforts to reorganize diyhpl.us documentation, moving amino-acid data tables out of an unused “FAQ” and adding proper MIME types for YAML goal/tech lists.
