# Key Points from #hplusroadmap IRC Discussion

• Participants discussed NanoEngineer-1 (NE-1), a molecular design tool for atomic-level DNA modeling and DNA origami, debating its utility for visual modeling versus sequence-based approaches while troubleshooting installation issues related to outdated dependencies.

• The concept of utility fog (introduced by J. Storrs Hall in 1993) was explored as a potential safety technology using molecular-sized robots that interlock to form protective solid structures during accidents.

• Researchers debated resolution requirements for CAD systems at nanoscale, questioning whether 32-bit systems (limited to 4 billion integer resolution) are sufficient or if 64-bit systems are necessary for precise molecular manufacturing.

• The SKDB (Skill/Standard Parts Database) project was discussed as a platform for multi-scale CAD modeling, with interest in bridging the gap between boundary representation models and atomic-level structures.

• Practical manufacturing challenges were addressed, including MakerBot 3D printer modifications to achieve 0.1mm positioning accuracy and the lack of Linux drivers for Epilog laser cutters.

• Participants envisioned hierarchical design approaches where "atoms make the DNA and the DNA makes the parts," potentially enabling higher-level engineering of materials like kilometer-scale solar-collecting roadways.

• Novel health technologies were mentioned, including color-shifting contact lenses for diabetics that provide visual glucose level indicators.
