# Key Points from IRC Log

• A discussion about 3D printing questioned the assumption that 3D printers need to be ubiquitous, with a link to a high-quality student project video called "Solar Sinter" (vimeo.com/25401444) showing advanced solar-powered 3D printing.

• Participants discussed space colonization strategies, arguing that asteroid colonization is more practical than planets ("gravity holes"), with debate about using centripetal force or train tracks around asteroids to generate artificial gravity versus using electric bone tissue stimulation to counter calcium loss.

• A user shared a presentation about DIY biology and transhumanism being prepared for an FBI meeting, focusing on practical transhumanism, orphan diseases, and patient advocacy as motivations for biohackers working outside traditional regulatory frameworks.

• The group discussed gene synthesis costs and technology, sharing links to research on microfluidic platforms that could reduce reagent consumption 100-fold while maintaining synthesis scale, with references to a paper on high-fidelity gene synthesis using pyrosequencing.

• A suggestion was made to create "nootstack.org" to organize and rate nootropic stacks, as existing communities like Reddit's r/nootropics lack structured information sharing compared to sites like imminst.org.

• Notes from a DIYbio FBI meeting revealed that authorities had previously raided someone conducting lentiviral engineering at home, but the district attorney couldn't press charges, suggesting legal gray areas in DIY biotechnology.
