# Key Points from #hplusroadmap IRC Discussion

• Participants debated energy collection methods, comparing space-based solar collectors to terrestrial installations, with detailed discussion of microwave transmission safety, environmental impact, and material durability challenges in harsh conditions.

• High-altitude wind power was analyzed as an alternative energy solution, with calculations suggesting a 100m diameter rotor at 13km altitude could generate 300MW, though significant engineering challenges remain for tower construction and maintenance.

• Material science limitations were highlighted through examples of rapid degradation in solar applications, where even UV-resistant materials like mylar failed to last a single summer in real-world conditions.

• The conversation touched on RNA abiogenesis research, referencing laboratory creation of RNA molecules, though some expressed skepticism about RNA being the first self-replicating molecule in evolution.

• Technical discussion covered automated design systems, particularly "a-design" software using "terminators" and "correlators" to create complete designs by ensuring proper variable bounding and dimensional analysis.

• The Golem project (Genetically Organized Lifelike Electro Mechanics) was mentioned in the context of evolutionary robotics, with speculation about using supercomputers to design printable robots.

• Participants explored computational approaches to cooking, including structured recipe formats like Recipe Exchange Markup Language (REML) and RXOL, which uses postfix notation to make recipes computer-processable.
