Bitcoin miners turn farm waste into carbon-negative power
- Bitcoin miners use biomass gasification to generate off-grid power, monetizing waste and soaking excess energy.
- Biochar byproduct rebuilds soil carbon, creating a 1,000-year fertility reservoir and locking away emissions.
- Projects like Cathedral aim to outlive civilizations by closing energy, carbon, and financial loops.
Bitcoin mining is no longer just a consumer of energy - it’s becoming a regenerative force. At the Cathedral Project, a long-term silvopasture experiment, the Carbon Group uses gasification to convert wood chips and walnut shells into syngas. This isn’t open-flame burning. It’s controlled pyrolysis in low-oxygen retorts, cracking biomass into hydrogen, carbon monoxide, and methane - fuel for modified internal combustion engines.
The farm doesn’t just avoid disposal fees - it earns tipping fees for accepting municipal wood waste. Waste heat from the gasifier, generator, and even the Bitcoin miners themselves dries incoming biomass in ag-silos, closing the thermal loop. Electricity powers farm operations first; excess flows to a one-megawatt mining container, turning stranded energy into liquid capital.
"Mining acts as a flexible load, converting excess wood-gas electricity into liquid capital."

But the real legacy isn’t electricity. It’s biochar - a porous, carbon-rich byproduct that acts as a magnetic sponge in soil. Industrial farming has depleted topsoil carbon from 17% to 2%. The Cathedral Project aims to push it to 25%, creating a nutrient reservoir that survives droughts and heavy rains. This is the "cathedral" vision: carbon locked in earth for a millennium, outlasting institutions.
The model flips ESG critiques of Bitcoin on their head. Instead of energy waste, it’s a closed-loop system: biomass in, power and coins out, biochar back into the land. The financial return from mining subsidizes century-scale land regeneration - a project designed to outlive its creators.
"This is the 'cathedral' aspect of the design. Rebuilding that soil profile takes decades of consistent application."

While other stories dominate headlines - BIP-110 governance fights, Coldcard vulnerabilities, Saylor’s debt bets - the Cathedral Project represents a quiet, tangible shift. Bitcoin mining isn’t just surviving in the energy debate. It’s evolving into a tool for carbon-negative infrastructure, one farm at a time.

AI Unwinds, Bitcoin Decides & the Middle East Realigns | Simon Dixon Hard Talk LIVE (Part One) • Jul 31
- Bitcoin's BIP 110 proposes reducing the mining consensus threshold from 95% to 55% for activation, with an approximate deadline for miner signaling around August 7th.
- A Coldcard hardware wallet entropy flaw affected seed phrase generation for specific versions issued approximately between 2021 and 2023, leading to compromised wallets.
- For Coldcard users potentially affected by the entropy flaw, Simon Dixon recommends updating firmware, generating a new seed in a calm environment, and moving funds with test transactions.

Fed (1)
- Simon Dixon alleges Citadel used insider information about Federal Reserve decisions, then bought substantial AI stock positions from a liquidated $25 billion leveraged hedge fund after an AI market crash and subsequent rebound.
Mining (1)
- Ionic Digital, a former Bitcoin mining company spun out of the Celsius bankruptcy, pivoted to AI infrastructure and went public on NASDAQ; Citadel was an early cornerstone investor.
Markets (1)
- US 10-year Treasury yields reached 4.6%, impacting mortgage and auto loan rates; Simon Dixon notes mortgage rates above 7% cause significant financial stress for consumers.
AI & Tech (1)
- Simon Dixon suggests AI will lead to widespread job displacement and increased wealth inequality, potentially necessitating a Universal Basic Income issued via stablecoins or CBDCs.
Diplomacy (2)
- Netanyahu's recent White House visit lacked customary red-carpet treatment, which Simon Dixon interprets as Israel's diminishing role as a 'Military Industrial Complex node' amid regional realignment.
- The Iran-Saudi normalization agreement, mediated by China in 2023, signifies a shift towards West Asia alignment and away from the 'Forever War' model, with proposed investments like $300 billion in Iran.
War (1)
- Simon Dixon views current Middle East conflicts, including actions in Gaza, Yemen, and Iraq, as strategic 'escalate to de-escalate' maneuvers leading to regional deals and a reduced US military footprint.
Politics (1)
- Control over critical choke points like the Strait of Hormuz, Bab al-Mandeb, and the Suez Canal is central to the emerging global order, with China seeking energy security and stability in the region.
Education (1)
- Simon Dixon's upcoming book, 'Game of Money,' aims to guide readers from 'subordinate to sovereign' across 21 chapters in three parts, covering financial, military, and technical industrial complexes.
Cathedral VI: The Carbon Group • Jul 28
- David Bennett's Cathedral Project is a 1,000-year modified silvopasture thought experiment in agriculture, designed to be a legacy system that no single generation expects to complete.
- The Cathedral Project operates under three core laws: yearly land fertility increase, maximized productivity without violating the first law, and minimal use of synthetic chemistry only when necessary to obey the first two.
- The Carbon Group, a central component of the Cathedral Project, processes biomass to generate energy, heat, electricity, carbon, and other products, all designed to cycle back into the wider system rather than creating waste.
- Feedstock for the Carbon Group includes on-site pruning waste, black walnut shells/hulls, and external municipal wood waste, which can incur tipping fees as revenue, with careful quality control to exclude contaminants like heavy metals from treated wood.
- Biomass is prepared by chipping it to a consistent size (e.g., 3 inches) and drying it to 12-15% moisture content in agricultural silos, utilizing waste heat from the gasifier, generator, and Bitcoin miners.
- Gasification, or pyrolysis, heats dried biomass in a low-oxygen environment (500-800°C) to produce syngas (60% hydrogen, 15% carbon monoxide, 5-10% methane), biochar, and wood vinegar.
- The cleaned syngas fuels a modified internal combustion engine that generates electricity for system operations, with excess power directed to Bitcoin miners as a flexible load to support the network and create revenue.
- Biochar, pure carbon produced from gasification, is a critical long-term soil fertility product, increasing water retention and nutrient availability, and providing habitat for beneficial soil microbiology.
- Wood vinegar, a condensed liquid from the gasification process, offers benefits for plant growth (e.g., increased seed germination) and can be used as a topical antimicrobial/antifungal for humans or mixed with biochar for soil application.
- David Bennett suggests that feeding 10% biochar to ruminant animals improves their performance and health while significantly reducing methane burps, addressing environmental concerns.
- The Cathedral Project aims for 20-25% carbon content in its soils, a level projected to take at least a quarter-century to achieve, enabling potential revenue generation through carbon credit sales due to biochar's long-term sequestration.
