# Key Points from IRC Discussion on #hplusroadmap

• Lunar manufacturing technologies were debated, with participants critiquing Gregory Chirikjian's Crookes radiometer proposal (which fails in vacuum conditions) and discussing alternative energy production methods including sterling engines, solar fields, and creating mirrors from lunar regolith.

• Economic implications of automated manufacturing were explored, referencing Kevin Carson's work on desktop manufacturing and raising concerns about how automation might lead to wealth concentration and economic restructuring.

• Several upcoming transhumanist conferences were highlighted, including events in the Netherlands, Colombia, Utah (Mormon Transhumanist Association), Italy (TransVision 2010), and Los Angeles (H+ Summit 2010).

• The FDA's reclassification of piracetam from supplement to drug status was noted as concerning for cognitive enhancement advocates, with discussion of alternative racetams including oxiracetam, aniracetam, and pramiracetam of varying potencies and solubility properties.

• Technical challenges in 3D printing rocket components were discussed, particularly issues with porosity in Direct Metal Laser Sintering (DMLS) for stainless steel parts, alongside a conversation about rocket engine clustering with reference to SpaceX's Falcon 9 design.

• Information was shared about OpenCog, an open-source artificial general intelligence project led by Ben Goertzel that evolved from Novamente, representing current work in AGI development.
