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.

S17 E35: Vinny Lingham on Bitcoin Post-Maximalism, Scaling Regrets & Saylor's Endgame • Aug 1
- Vinny Lingham expresses concern that when Bitcoin's block rewards diminish in 8-12 years, insufficient transaction fees, coupled with price stagnation below $100K and hash power fragmentation across forks, could compromise network security against state-actor attacks.
Also from this episode: (12)
Protocol (7)
- Vinny Lingham co-founded Praxus Capital and has been involved with Bitcoin for 15 years, starting in 2012 when his company, Gift, accepted Bitcoin for gift cards to mitigate high payment chargebacks and international fraud.
- Vinny Lingham contends the 2017 scaling wars and subsequent block size constraint led to the proliferation of the altcoin ecosystem, as Bitcoin's fees became prohibitive and the community resisted scaling to become a global payment system.
- Vinny Lingham criticizes Bitcoin Core's centralization, claiming Blockstream effectively controls it by employing developers and pruning dissenting voices, leading to a lack of diverse thought and divergence from Bitcoin's original white paper vision.
- Vinny Lingham describes Michael Saylor's consolidation of Bitcoin through MicroStrategy as creating systemic risk, potentially enabling him to crash a minority fork by selling his holdings.
- Vinny Lingham notes Solana handles 3,000 transactions per second, significantly more than Bitcoin's 7 transactions per second, making it suitable for high-volume use cases like World Series of Poker buy-ins.
- Vinny Lingham reports Elon Musk disengaged from Bitcoin around 2021 after conversing with Adam Back and others, perceiving they had "lost the plot," and has not spoken about Bitcoin in five years.
- Vinny Lingham believes August will be a challenging month for Michael Saylor due to potential network disruptions from upcoming hard forks like BIP 110 and eCash, and MicroStrategy's unverified reserves.
Payments (1)
- Gift processed 100,000 Bitcoin transactions over 2-2.5 years with zero double spends by accepting zero-confirmation payments for values up to $2,000, before RBF was implemented in 2015.
Lightning (1)
- Vinny Lingham states Lightning Network, despite 10-11 years of development, does not work at scale, nor do Ethereum's Layer 2 solutions, as they economically deprive the Layer 1 of necessary security fees.
BTC Markets (2)
- Vinny Lingham believes Bitcoin is a "store of liquidity," not value, experiencing significant price swings due to market liquidity shifts and underperforming Nasdaq and gold over the past few years.
- Vinny Lingham postulates Bitcoin's price would exceed $100,000 with a stable, consistent 12-15% annual growth if it had scaled as a global payment system, fostering deeper liquidity and mitigating boom-bust cycles.
Macro (1)
- Vinny Lingham cites gold as a true store of value, noting 1 ounce could buy a tailored suit 100 years ago and still costs approximately $4,000 today, demonstrating consistent purchasing power.
AI Unwinds, Bitcoin Decides & the Middle East Realigns | Simon Dixon Hard Talk LIVE (Part One) • Jul 31
- 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.
- 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.
- 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.

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.
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.
Cathedral VI: The Carbon Group • Jul 28
- 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.
- 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.

Longevity (1)
- 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.
Biology (4)
- 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.
- 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.
Physics (1)
- 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.
Climate (1)
- 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.
