# Summary of #hplusroadmap IRC Log (Jan 27, 2009)

* Several nanotechnology resources were shared, including Project Aten (atomic coordinates library), a web-accessible nanotube structure generator, and Java-based nanotube visualization tools.

* A "Cloaca" machine was discussed that simulates human digestion, taking food, stomach acids, and GI tract enzymes as inputs and producing fecal matter as output, representing an artificial biological system.

* A mathematical paper on "graph pegging" was shared, describing a system where graph vertices are treated as holes for pegs with checker-like moves, with applications to graph theory problems.

* A biomimetic robot for space exploration was highlighted that combines grasshopper-like jumping with ball-like rolling capabilities, with commentary suggesting that Lipson's work could lead to fabrication technology (like Fab@Home) on Mars.

* An extended discussion about economic systems occurred, contrasting traditional money-based exchange with gift economies and "open money" as a potential transition mechanism toward post-scarcity economics.

* Modafinil (Provigil) synthesis was discussed, with participants sharing resources about the difficulty of synthesizing this cognitive enhancement drug and linking to documentation on synthesizing both modafinil and its precursor adrafinil.

* RepRap 3D printer technology was briefly discussed, with the observation that its growth pattern is "hyperbolic" and the suggestion that this growth pattern could be formally documented in a research paper.
