- Ichor Life Sciences, a “garage biotech” startup profiled at https://ichorlifesciences.com/about/, was highlighted as an example of grassroots transhumanist entrepreneurship.  
- A detailed thermodynamic discussion compared the latent heat of CaCl₂ hydration: initial claims of ~2.6 MJ per 100 g were corrected to ~0.4 MJ kg⁻¹ for the dihydrate→hexahydrate transition, still ~1.6× better than Glauber’s salt and ~16× water evaporation per unit mass of water involved.  
- Participants explored using reversible salt hydration as a compact, wearable cooling medium, noting corrosion risks with most metals except silver.  
- Entropy-sink engineering ideas were proposed: confining NaCl or diamond nanocrystals in spherical cavities to force high-entropy disordered states, then releasing them to low-entropy crystalline forms to extract heat—leveraging the phase-space bottleneck created by geometric constraints.  
- The conversation linked to a personal notebook (https://derctuo.github.io/notes/muriate-thermal-mass.html) containing step-by-step enthalpy calculations for CaCl₂ hydrates.
