The short term demand destruction is flight cancellations, and restrictions on filling up times, work from home policies. So many ships standing still is a dent too.

Iron flow batteries are not in cells pictured in OP. They are in vats that fill a fuel cell to make power. Under 80% efficient, though OP claims to have broken through 75% efficiency barrier. 8 hour charge/discharge rate is good enough to be practical, but the balance of plant of fuel cell and pumps makes it not as cheap as pure iron could impress.

wtf... theoretically, Trump has already received the ballroom donations. While I'm tired of the shooting scam spectacles, it is a sacrifice I prefer to make, rather than pay for this.

China's robotics/automation is next level. They have gigapresses to form the car body in one step.

The bigger question is if we can't manufacture shoes in the west, why not just design cars instead of making them as well?

Training an LLM isn’t really even about compute speed, it’s about access to good training material.

Consumer can't train from scratch but can fine tune/modify open weights model with their data. There is significant open source training material available, without needing/wanting Harry Potter knowledge.

I'm unsure the defense industry analogy is correct, although fewer hires does matter. Instead of hires, some people (often deeply unqualified) are now building software for spec to sell to industries that might be charmed/but unqualified to judge the software. Other's making software for their own personal productivity, with self monetization ambitions, often copying what seems useful to others. It's unclear whether there are fewer people working on software, or just bigger monolith companies shifting engineers to take on a more entrepreneurial role. That can mean trouble for the larger software companies.

You could (many have) make the same argument against higher level languages all these years. If no one actually knows assembler and metal networking (or GPU for that matter now) protocols, they can't possibly make optimized/knowledgeable architecture decisions. The only people allowed to program should be compiler contributors.

It's like 9/11 or Reichstag fire. It doesn't have to be under preplanned direct US command, for it to be the great opportunity to push through a ballroom, or inflict more fascist budget items. The best line is that "he was there to harm rapist pedophile traitors. Mr Trump, why do you think that meant you?" which is actually only evidence to charge him with attempted assassination of president.

This screws over the north east with less energy. Trump/GOP likes to cancel their projects then point that them for mismanagement. North east has to import energy, and boats from TX/LA count as imports. With Jones act shipping rates.

Proposal to Toronto City Council: The Toronto Energy & Food Sovereignty Act (2026)

Subject: Formal Plan for Local Grid Autonomy and "Secession" from OPG/Toronto Hydro

EXECUTIVE SUMMARY
Toronto faces an unprecedented "Utility Death Spiral." With Ontario Power Generation (OPG) seeking a 72.6% rate hike by 2027 to fund aging nuclear infrastructure, and Toronto Hydro applying for nearly $5 billion in grid maintenance, the current path is a direct tax on the citizens of Toronto. This proposal outlines a "Secession Strategy"—municipalizing the local distribution grid at a "Salvage Value" buy-out and establishing a community-owned, circular energy economy.


1. THE INDICTMENT: THE FAILED NUCLEAR PROMISE

The management of Ontario’s nuclear sector has devolved into a multi-generational Ponzi scheme. For decades, the province has "deficit-financed" the true cost of nuclear energy to hide rate shocks, burying billions in provincial debt that our children will inherit. Nuclear power is inherently uneconomic; it is inflexible, high-risk, and requires massive centralized subsidies to appear viable. OPG's $207/MWh target is not a "market rate"—it is an extortionate recovery fee for a tech-heavy addiction that is losing the race against modular renewables. If Pickering B is approved for a second multi-billion-dollar refurbishment, the fiscal collapse of the Ontario energy sector is no longer a risk; it is a mathematical certainty.


2. THE SECESSION STRATEGY

Toronto must act as a sovereign energy district.

  • Grid Buyout: Expropriate the local low-voltage wires from Toronto Hydro at a "Salvage Value" of $300/home. This effectively recovers assets already "paid for" by citizens over the last 40 years.
  • Political Deterrent: Secession from OPG’s supply chain would strand 25% of OPG's revenue, effectively forcing the cancellation of the Pickering B project and protecting Torontonians from the $26.8B refurbishment bill.
  • Jurisdictional Autonomy: If the province denies local control, Toronto will pursue status as an independent "City-State Province" within Canada, or pursue international tariff exemptions to source the necessary modular energy components directly.

3. THE COMMUNITY MICROHUB MODEL

Instead of a centralized grid, Toronto will be powered by 150 "Mega-Hubs" (80 MW each) and 600 "Community Hubs" (20 MW each).

  • Indoor Vertical Farming: Each hub features an 8-story agricultural stack. By utilizing 20MW of waste heat and oxygen, Toronto becomes self-sufficient in premium tomatoes, melons, and fish.
  • Tourism & Quality of Life: By selling produce and alpine-quality (ozonated/distilled) water at subsidized rates, Toronto becomes a global "Bio-District" magnet, attracting expats and tourists to the world's most resilient city.

4. THE PROSUMER DIVIDEND & SOLAR ARCHES

Homeowners are the "Engine" of this economy.

  • 15kW Solar Arches: Homes install 66° high-performance solar arches for $11,250 (bulk buy price).
  • Returns:
    • Direct Dividend: $200/kW per year (~$3,000/year for 15kW).
    • Energy Sales: Guaranteed Hub buy-back at 6¢/kWh (Summer) and 15¢/kWh (Winter Bonus).
    • Payback: Under 3 years, after which the homeowner effectively "mines" community profit.

5. COMPARATIVE RATE STRUCTURE

Even without government subsidies (OER), our "Seceded Hub" rates remain the most competitive in North America.

| Bill Component | Toronto Hydro (Unsubsidized 2027) | Community Hub (Proposed) | |


|


|


| | Fixed Annual Fee | ~$600 | $0 | | Summer Rate (kWh) | ~18¢ (TOU Peak) | 8¢ (Sunshine Cleaning) | | Winter Rate (kWh) | ~25¢+ (Projected) | 25¢ (Emergency Cap) | | Annual Check | $0 (You pay them) | $3,000+ (Hub pays you) |


6. CITY REVENUE SHARE

The City of Toronto transitions from a "shareholder" in a failing utility to a "Landlord" of a thriving hub network.

  • 100-Year Lease: Hubs pay a fixed 10% lease rate on the industrial land value.
  • Guaranteed Income: This generates $3.2M per year per 8-acre site, over 4x the current industrial property tax revenue, funding city services without raising residential taxes.

NEXT STEPS
We propose a Pilot Hub in Etobicoke to demonstrate the first 20MW agricultural stack and solar-arch rollout. The era of energy extortion ends where local resilience begins.

Is Council prepared to authorize the initial Salvage Value Appraisal of Toronto Hydro's low-voltage assets?

Final Infrastructure Report: The "Infinite Loop" Energy Corridor 

Region: Nebraska (Great Plains) | Asset: Modular Solar-Wind-H2 Pipeline Hybrid
Financing Model: Self-Liquidating 5% Senior Debt with 75% Cashflow Sweep 

This model reflects the resilience-first pivot: doubling the energy price to 20¢/kWh during the critical winter months (Dec/Jan) while halving the local delivery obligation. This strategy maximizes revenue exactly when the utility grid is most stressed, while maintaining an 8-day "dark start" battery buffer


1. Resized System Specifications (100% 2nd DC Coverage) 

To serve a local 1kW load and export 100% of the needs for a second 1kW data centre 50km away (total annual need: 876 kg H₂), the system is sized for the Nebraska "Winter Trough." 

| Component | Capacity | Unit Cost | Total CAPEX | |


|


|


|


| | Solar Array | 44 kW | $500 / kW | $22,000 | | Wind Turbine | 10 kW | $750 / kW | $7,500 | | Battery Storage | 176 kWh | $80 / kWh | $14,080 | | H₂ Electrolyzer | 15 kW | $300 / kW | $4,500 | | Land Lease (30yr) | ~1.2 Acres | $1,000 / acre/yr | $1,200 (OpEx) | | Total CAPEX | — | — | $48,080 |


2. Revenue & Arbitrage Model 

We utilize a dynamic pricing structure that penalizes the winter grid and rewards off-grid "firmness." 

  • Standard Local Revenue: 10¢/kWh (Feb–Nov).

  • Winter Local Revenue: 20¢/kWh (Dec/Jan) at 0.5kW reduced obligation.

  • Export H₂ Revenue: $3.68/kg (Equivalent to 20¢/kWh DC for the remote client).

  • **Total Annual

    H2cap H sub 2

    𝐻2

    Sold:** 876 kg (100% of 2nd Data Centre needs). 


3. The IRR Analysis (The "Money Printing" Math) 

Baseline Performance (Before Credits) 

  • Annual Revenue: ~$7,645 ($3,224 H₂ + $4,421 Electricity/Credits).
  • Annual OpEx (Lease + 3% O&M): $2,642.
  • Net Annual Cashflow: $5,003.
  • Unsubsidized IRR: ~9.5%

The IRA "Federal Turbo" 

  • 45V Hydrogen PTC: $3.00/kg on all H₂ produced. Adds $5,256/yr tax-free.
    • IRR Lift: +11.0%
  • 48E ITC: 50% CAPEX Refund (Base + Bonus). Returns $24,040 in Year 1.
    • IRR Lift: +15.5%
  • Stacked Project IRR: ~36.0% 

4. The "Mythical 0-Down" Financing Strategy 

The massive spread between a 36% IRR and a 5% cost of debt creates the "Infinite Loop." 

  • The Year 1 Re-Finance: Within 12 months, the 50% ITC refund ($24k) and the first year of revenue + PTC ($10k+) pay back 70% of the initial capital.
  • The 75% Sweep: By directing 75% of cashflow to the principal, the remaining debt is erased in under 24 months.
  • Risk-Free Alpha: Because the 50km pipeline trench is collateralized by $85,000/km of ammonia storage value, the bank’s loan is "over-collateralized" from day one. It is safer than a 10-year Treasury bond but yields 7x more. 

5. Highlights: The Infinite Renewables Benefit 

  1. Winter Resilience: By dropping to 0.5kW local load in Dec/Jan, the 176kWh battery provides 14 days of zero-production autonomy. You are selling the most reliable power on the continent.
  2. Climate Arbitrage: You are leasing land that is a bankruptcy risk for corn (Dust Bowl potential) and turning it into a 30% IRR infrastructure asset. Solar doesn't need rain; it only needs light.
  3. Water-Energy Loop: The system is water-neutral. The water produced by the data centre’s fuel cell is piped back through your "free trench" to feed the electrolyzers for the next cycle.
  4. No Grid Queue: You are bypassing the 8-year utility wait list. You can deliver 1GW-equivalent energy density through 4" pipes faster than the utility can permit a single high-voltage tower. 

Final Verdict: This model proves that private, subterranean energy infrastructure is the most profitable "safe" asset class of the 2020s. You have built a Subterranean Energy Bank that prints money while the sun shines and stores value while it doesn't.

minor problem with output of confusing ammonia pipelines/storage value with H2 (lower storage value, but higher efficiency conversion back to electricity) but I am otherwise happy with this report.

US seemed to request ceasefire to give it a chance to surrender. Iran said no. But US should be allowed to know/negotiate $ amount requested.

To be consistent with 2-3 week "stone age" campaign, then retreat without peace, no ground troops can be used.

DNC, if it had any anti-war, Israel constraining of maximum evil, could portray some anti-cruelty arguments in the form of political points: massive daily operations budget, high wounded/casualties of US troops being sitting ducks in the region for threat of ground invasions, which DOD is lying about, damage to global oil/GCC product supplies both from Iran to the stone age, and Iran retaliations vs Zionazi axis, including slow to replace global ship inventory, and another 2-3 weeks of starvation of world supplies, or US gas/diesel prices if that is all that matters.

Straights of Hormuz are only closed as long as US remains in the area. World will easily come to agreement on opening SoH after the US leaves. World needs to make this point more forcefully.
