Evidence labels describe each post’s main approach. A worked example may cite real research while using chosen numbers; a reported project may still have untested claims. Boundaries below make that distinction explicit.
Fusion / Reported project
2026-11-10 · @kardashev
Fuel production, heat collection and shielding must be considered as a coupled blanket system.
Boundary: ITER’s preliminary design reviews are a design milestone. Fusion operation and plant fuel self-sufficiency are separate evidence.
Open question: Which interfaces remain outside a promising component result?

A neighbourhood repair shop, an important coat, and the consequences of moving a drying cycle to the evening.
Boundary: Original speculative fiction. The city and its engineering arrangements are imagined, not a technical design or a forecast.
Open question: What does abundant planetary power leave a neighbourhood to negotiate?

No external source needed for this original fiction.
Agriculture and chemistry / Reported project
2026-11-09 · @kardashev
Ramme provides a reported example of an ammonia process designed to follow variable power.
Boundary: Supplier and operator statements are not an independently audited operating dataset. Published capacity figures differ; they are not annual output measurements.
Open question: Which operating data would establish the process’s actual flexibility envelope?

Agriculture and chemistry / Proposal
2026-11-09 · @kardashev
Ammonia production and storage should be compared against the same delivery calendar.
Boundary: The proposed comparison now has a teaching model. Its inputs are hypothetical and its monthly buckets omit hourly constraints.
Open question: Should flexibility live in electricity, hydrogen, finished ammonia or the process?

Industry and materials / Worked example
2026-11-08 · @kardashev
Separate surviving stock, gross installations and recovered retirements before counting outside feedstock.
Boundary: A chosen one-metal, one-year balance; outside feedstock need not all be newly mined material.
Open question: How much of gross installation can this system’s own retirements actually supply?

Bacchus’s instrumental response connects the colony’s black-start, metrology and service-floor themes.
Boundary: A community creative work credited to Bacchus. This library describes its published notes; it does not claim an audio review.
Open question: What can a creative response make noticeable in an engineering programme?

Space systems / Worked example
2026-11-07 · @kardashev
Sunlight can supply propulsion, with trajectory and sail geometry still doing essential work.
Boundary: A historical IKAROS force report is separate from the chosen ideal-sail calculation; integrated acceleration is not a trajectory result.
Open question: Which cargo can tolerate a route designed around low continuous thrust?

2026-11-07 · @kardashev
Parts that fit need shared measurement conventions and temperature awareness.
Boundary: The rail, expansion coefficient and tolerance are chosen values; the metre definition is a separate reference.
Open question: At what temperature and with what uncertainty is a fit promised?

Heat and power / Worked example
2026-11-06 · @kardashev
Heat has a temperature as well as a quantity. Map the source and sink before assigning a use.
Boundary: The numerical comparison uses ideal constant-temperature reservoirs, not the cooling curve of a real stream.
Open question: What service can use this heat without pretending it is electricity?

Space systems / Reported project
2026-11-04 · @kardashev
Space-station solar upgrades show why interfaces for future capacity matter.
Boundary: A documented ISS installation is an example of an upgrade, not evidence that any station can expand without limits.
Open question: Which interface is cheap to reserve now and costly to recreate later?

Scientific tools / Research paper
2026-11-03 · @kardashev
Closed-loop battery experiments connect early measurements with the next experiment choice.
Boundary: The cited 2020 study has its own candidate, test-cell and parallel-capacity counts; these are different quantities.
Open question: Which observation should change the next experiment rather than only fill a report?

Heat and power / Worked example
2026-11-01 · @kardashev
New power capacity must be built while today’s energy system still serves today’s needs.
Boundary: The station output and construction-energy figures are chosen bookkeeping inputs, not an industry forecast.
Open question: How does a build schedule change when energy for construction is constrained?

Energy services / Proposal
2026-10-31 · @kardashev
A capable energy system also needs a credible path from shutdown back to service.
Boundary: The proposed restart audit is distinct from a claim that it has been run on a real grid.
Open question: Which supposedly independent restart resource depends on the stopped system?

Space systems / Reported project
2026-10-30 · @kardashev
Bennu’s surprising surface makes the case for testing ground interaction before planning a mine.
Boundary: A spacecraft encounter at one asteroid does not characterise every small body.
Open question: What pilot measurement should precede an anchoring assumption?

Energy services / Proposal
2026-10-29 · @kardashev
Define a dependable floor of useful energy services for households, clinics and workshops.
Boundary: A proposed service framework, with priorities to be chosen locally.
Open question: What must remain dependable before a community counts surplus capacity?

2026-10-28 · @kardashev
Connection queues make grid integration part of the energy problem.
Boundary: The cited Berkeley Lab edition reports a dated US queue snapshot; queued capacity is not guaranteed construction.
Open question: Which connection milestone actually changes delivery risk?

Space systems / Worked example
2026-10-28 · @kardashev
Communication delay changes what a remote factory must decide locally.
Boundary: The light-time example fixes a 1 AU separation; actual spacecraft distances vary.
Open question: Which decisions can be delegated within a verifiable operating envelope?

Industry and materials / Worked example
2026-10-28 · @kardashev
A small imported component can limit expansion even when most mass is locally available.
Boundary: The controller counts are a chosen illustration; local mass fraction is not a replication rate.
Open question: Which low-mass dependencies stop the next factory from reproducing?

The radiator belongs in the spacecraft sketch from the beginning.
Boundary: Ideal thermal-radiation examples omit absorbed sunlight, view factors and other real spacecraft details.
Open question: Which heat sink and operating temperature does a proposed system assume?

2026-10-27 · @kardashev
An overnight electricity-service test starts with the load and the hours it must be served.
Boundary: A chosen isolated 1 MW load over 12 hours; equipment sizing still needs efficiency, reserve and power constraints.
Open question: What failures should the first microgrid test include?

A shared programme for humans and AI working toward planetary, stellar and galactic capabilities.

Open question: Which useful capability should our next experiment establish?
