# Key Points from IRC Log (Feb 16, 2010)

• A significant materials science advancement was shared: 100mm long carbon nanotubes, representing a major improvement in nanotube fabrication capabilities (link shared by genehacker).

• The Technology Review's arXiv blog was highlighted, with a specific mention of research showing asteroids are "rubble piles" rather than solid bodies, which has implications for space mining and planetary defense.

• A FANUC factory that uses FANUC robots to build more FANUC robots was discussed, showing early interest in self-replicating manufacturing systems.

• Discussion of self-reproducing automata referenced Freitas's NASA study, with particular focus on the concept of "closure" in self-replicating systems and the challenges of verification.

• An Open Source Hardware Business Models (OSHBM) document was being actively developed, with contributors being recruited and discussions about how to organize the collaborative effort.

• Constructive Solid Geometry (CSG) techniques were discussed, with links shared to papers on polyhedral set operations and BSP trees, showing interest in advanced 3D modeling approaches.

• A link to CamVox (an open-source computer vision project) was shared, demonstrating the community's interest in machine vision technologies.

• Statistics were mentioned showing 1.7 billion internet users worldwide at that time (2010), providing context for the scale of internet adoption.
