## Summary

Hosts Elliot Williams and Dan Maloney review a week of hardware hacks, highlighting Gilliam de Charpentier’s CNC-milled ‘Carpentopod’ coffee table with custom Strandbeest-style linkages and Daryl’s solar-powered water heater that uses thermal mass instead of lithium batteries. They also discuss The Thought Emporium’s potato-based cyanotype photography, Lisa Fagan Davis’s multi-spectral analysis of the Voynich Manuscript, and Joe Bernard’s cross-sectioned Solid Propellant Rocket Motor (Simplex V2). The episode concludes with commentary on the ‘Small Web’ via the Gemini protocol and the scalability challenges of biomass energy.
