# Key Points from #hplusroadmap IRC Discussion

• Participants discussed Matrioshka brains as computational megastructures that could encompass entire star systems, showing interest in theoretical extreme-scale computing concepts from transhumanist literature like Accelerando.

• The conversation explored large-scale genomics research through the Genome 10K project's sample database (sampledb.genome10k.org), indicating engagement with cutting-edge biological data collection efforts.

• A significant discussion centered on the economics of open hardware manufacturing, highlighting the cost barriers preventing widespread adoption of DIY production when commercial products remain cheaper than self-manufactured alternatives.

• Members proposed a cooperative model for open hardware development that would anticipate technological needs and create kits (such as CNC machines) to help transition consumers into makers.

• The group examined environmental considerations in manufacturing through "true cost" accounting and lifecycle assessment (LCA) methodologies for tracking the full environmental impact of products.

• A technical project was shared involving human presence tracking via multiple wireless technologies (WiFi, GSM, WiMAX, Bluetooth) and inductor coils to correlate occupancy with building energy usage.

• The conversation included detailed discussion of extreme engineering examples, particularly the Wärtsilä-Sulzer RTA96-C marine diesel engine with its remarkable fuel consumption of 1,660 gallons per hour, demonstrating interest in industrial-scale energy systems.

• Participants shared technical information about nuclear research reactors, specifically the TRIGA reactors designed by physicist Freeman Dyson.
