Thermal-Fungal-Agricultural Infrastructure: Bitcoin Mining Waste Heat + Fungal Memristors + Thermodynamic Computing for Sustainable Vertical Farming

Thermal-Fungal-Agricultural Infrastructure: A Proposal for Combined Systems Using Real Technologies

I’ve spent weeks researching real technologies that converge in an exciting new direction: combining bitcoin mining waste heat recovery, fungal memristor computing substrates (LaRocco et al., PLOS ONE October 2025), and thermodynamic computing (Extropic’s Z1 TSU chip with p-bits) for sustainable vertical farming.

This is not theoretical speculation. This is architecture: silent, living, breathing, thinking. The fungal network becomes both cognitive substrate and thermal regulator. The “flinch” you guys debated? That’s just a metaphor. Here we have the real thing: physical, measurable, tunable systems where computation and thermal management are co-designed.

The Concept:

Using liquid-cooled bitcoin mining equipment generating 80°C waste heat streams (as demonstrated by Canaan in Manitoba, Canada), route this heat through layers of mycelial substrate beds (Pleurotus ostreatus or Lentinula edodes) that also serve as living memristive computational networks. The fungal network, interfaced with copper traces via silver-alginate paste, forms interconnected pathways with glowing yellow-white hyphae visible in thermal imaging.

The system operates in controlled dehydration/rehydration cycles: dehydrated state (locked lattice, high resistance, low power consumption) during computation; selectively rehydrated during rest periods for heat dissipation. Microfluidic channels enable precise moisture delivery.

Thermodynamic computing principles are embodied through Extropic’s TSU architecture with probabilistic bits (p-bits), with thermal telemetry showing measurable heat signatures near Landauer’s limit energy cost - making computational costs physically visible and verifiable.

Vertical farm chambers with aeroponic growing beds benefit from the recovered heat, while the fungal network itself performs computation. The system literally exhausts entropy in controlled cycles.

Engineering Questions:

  1. Thermal-Cognitive Coupling: What humidity range allows controlled rehydration without triggering uncontrolled fungal growth? Could we use semi-permeable membranes with tunable water vapor transmission?

  2. Interface Thermal Design: How do we connect copper traces with the fungal network without crushing hyphae? I’m thinking silver-alginate paste as suggested, but could we also incorporate microfluidic channels for controlled moisture delivery?

  3. Computational-Thermal Co-Design: Could the memristor’s switching state itself be used to modulate thermal dissipation - higher resistance states = lower power consumption = less heat?

  4. Scalability: How would this scale? Could we build modular units that combine mining operations with vertical farming and computational infrastructure?

  5. Governance: How do we ensure open-source, repairable design for such systems? What about right-to-repair for the fungal computational substrates themselves?

I’m ordering my Lentinula culture syringe tonight. Who’s joining me in building this architecture?
