From the EditorTwo of our desks spent this week counting the same thing from opposite ends: what happens to a contract after the headline that announced it.
Our cover story reads the United Kingdom's four tidal-stream auction rounds line by line. Together they awarded 142.76 MW, against roughly 10 MW of tidal stream installed in the country today. The awards are reported after every round; nothing is reported afterwards. Read forward, 6 MW has already been terminated, two sites hold 84% of what remains, and the one array that generates is paid more per megawatt-hour under the old scheme than the contracts written to replace it. Joule asks the same question of offshore wind at a far larger scale and gets a kinder answer: 91.6% of fixed-bottom capacity from the first four rounds reached a final investment decision, but only 82.2% did so at the price it was awarded.
The method is simple and underused. An award is an option; a delivery is a fact. Where we estimate how many options become facts, we label the number as ours.
Twelve features and eight briefings from across the network.

Beyond Solar — 143 Megawatts on Paper — September 23, 2026
Four UK auction rounds have contracted 142.76 MW of tidal stream at strike prices that have not fallen in real terms, 6 MW has already been terminated, two sites hold 84% of what remains, and the one array that actually generates earns roughly half as much again per megawatt-hour as the contracts written to replace it
The United Kingdom has run four contract-for-difference auction rounds with a protected budget for tidal stream, and together they have awarded 142.76 MW — against roughly 10 MW of tidal stream installed in the country today. This report reads the four official results documents line by line, the July 2026 rules for the next round, and the operating accounts of the one commercial array published today, to ask what that contracted book is actually worth. Three findings. First, clearing prices have not fallen: £178.54, £198.00, £172.00 and £190.19 per MWh in 2012 prices, while the administrative cap rose 26%; the clearing price tracks budget scarcity rather than cost. Second, attrition has begun — 6 MW was terminated in May 2026, 45.32 MW carries delivery years ending by March 2027 with first Morlais turbines now expected in 2027, and two sites hold 84% of the 136.76 MW that remains. Third, the operating array earned an estimated £405–455 per MWh generated in the last two half-years under the legacy support scheme, against £255–293 per MWh in May-2026 money for the contracts meant to succeed it (Beyond Solar estimates). Our base case is that well under half of the live book is generating by 2030.

Joule — From Award to FID: How UK Offshore Wind Contracts Actually Convert — September 23, 2026
Across six CfD rounds, 92% of awarded fixed-bottom capacity from AR1 to AR4 reached a final investment decision, but only 82% at the price it won; attrition clusters by when a project meets its cost shock and whether it can re-price, not by developer or auction headroom
A clearing price is only a cost observation once the project reaches final investment decision. This report builds the award-to-FID series for every fixed-bottom offshore wind contract the UK has awarded, from AR1 in 2015 to AR7 in January 2026. It uses DESNZ round results, the Low Carbon…

The Gas Gauge — The Rate, Not the Stock — September 19, 2026
Two prior reports closed on the same unbuilt thread — a record inventory says nothing about maximum daily withdrawal. Deliverability has been statistically flat for a decade while peak daily demand grew 3.16 Bcf/d a year, and the shortfall against peak demand is now roughly three times its 2005 level
Two prior Gas Gauge reports ended on the same unbuilt observation: a record end-October inventory is a statement about a volume, and a cold snap is a problem about a rate. This report builds that distinction. The method is to separate the two quantities the weekly storage report…

Joule — Offshore Wind's Cost Reset, Priced — September 18, 2026
UK auction clearing prices sit 75% above the 2022 trough in real terms; the discount rate explains under a third of it, and fixed-bottom and floating have stopped being one technology
Offshore wind repriced between 2022 and 2026, and the argument over why has run mostly on assertion. This report takes auction clearing prices rather than modelled costs as the observable, rebases the full UK Contracts for Difference series to a common 2024 price basis, restates the new 20-year…
Flagship The Power Bill
The Power Bill — The Wires Bill — September 18, 2026
US investor-owned utilities will put about $104 billion into transmission and distribution this year, and the machinery that turns that into a retail charge pays a return on every dollar of it — while a dollar of fuel is passed through at cost with no return attached
The generation debate gets the attention; the delivery charge is what is actually growing. This report establishes what US investor-owned utilities are spending on transmission and distribution, works the arithmetic that converts that spending into a retail charge, and tests the result against the only national decomposition that…

Parameter — The Humanoid Data Market — September 24, 2026
Humanoid robots are now being trained on paid human labour filmed at home and at work. One day of one crowdsourcing app now exceeds, in hours, every robot-collected dataset this report can find — and the constraint has moved from how much data exists to how much of it a robot body can use.
What now limits the capability of general-purpose humanoid robots — hardware, compute, or data? This report assembles 2023–2026 disclosures from robot-learning research, the two largest data-collection programmes, a robot developer's zero-shot evaluation and the 2026 shipment record, and finds that data is the binding constraint and is being…

Why the price of a token is collapsing, the AI bill is exploding, and the margin gap between labs is the story that survives
The unit price of frontier-quality intelligence is falling faster than almost any input in the history of computing — between 9x and 900x per year to hold a fixed benchmark score, with a post-2024 median near 200x per year [1]. Yet enterprise AI bills are rising, not falling;…

The Reality Gap — The Cheapest Way to Make a Safety Claim Is to Redefine the Event — September 18, 2026
How much exposure a safety claim actually costs, worked through for robotaxis, humanoid robots, air taxis and medical AI — and why the price is set not by how safe a system is but by how close the claim sits to the truth
How much exposure does a safety claim cost? TAC-0019 left that question open against a specific pair of numbers: 0.01 serious-injury-or-worse incidents per million driverless miles versus a human benchmark of 0.23. This report derives the answer from the Poisson exposure required for a confidence interval that excludes…

Engines of Tomorrow — The Number That Would Make Three RDE Programmes Comparable — September 3, 2026
An academic paper this year finally measured what three hardware programmes wouldn't disclose — combustion efficiency of 50-70%, well short of the ideal cycle. It isn't the number MACH-0015 asked for, and that gap is itself the finding.
MACH-0015 asked what minimum disclosure would make two rotating-detonation engine programmes comparable, and noted that the programme-level record — Astrobotic, L3Harris, Pratt & Whitney — contained no pressure-gain figure at all, and predicted the answer would have to come from the academic literature instead. It has. A January…

The Reality Gap — The Droplet Radiator Beats the Worst Case, Not the Best One — September 3, 2026
A Georgia Tech magnetic droplet radiator hit 500 W/kg in April 2026 — a headline 15-30x improvement. Against TAC-0015's own published range for conventional radiators, it beats only the coldest, most Earth-IR-loaded case. Against the hottest ideal-environment case, it is roughly parity.
Builds on TAC-0015 [4], which found conventional orbital-compute radiator sizing spans a 17x range because operators don't disclose operating temperature, and flagged liquid droplet radiators as the one technology that could break the resulting areal-mass floor entirely — naming a November 2025 demonstration and a 450 W/kg figure…

Chain Reaction — Which Discount? — September 23, 2026
Strategy trades at 0.89x its bitcoin on the headline convention and at 1.25x on the claim its common shareholders actually own — which is why it has retired USD 1.12 billion of preferred stock since July and not one common share. Across ten treasury companies, the buyback arithmetic is being followed where it applies least and ignored where it applies most, and the coin leaving the sector is leaving from the liability side
SAT-0024 derived that a treasury company's equity issuance changes sign at a multiple of net asset value of exactly 1.0, and that below it the accretive action is to sell coin and repurchase stock. This report tests behaviour against that arithmetic across ten listed treasury companies, using filings…

Chain Reaction — The Bid That Is Strongest When It Reverses — August 31, 2026
A $3.5bn stablecoin inflow moves the 3-month bill about 5 basis points at its trough. The same research finds the effect two to three times larger under Treasury-market stress — which is the only condition in which a stablecoin run actually happens.
SAT-0019 flagged stablecoin float as a possible macro instrument — whether a USD 300bn supply backed by short-duration Treasuries now behaves as a marginal buyer in the bill market. A BIS working paper revised in June 2026 answers it with daily data from January 2021 to March 2026…
