Turyshev's preprint (April 2026) treats radiator area as part of its base-case mass model, with about 2,500 m2 of radiator for 1 MW of IT power, and concludes that general compute for terrestrial users closes only when several conditions hold together.

Paraphrase

for a 1 MW IT-power case the base case gives a radiator area of 2.50 × 10^3 m², with 29.4 kg/kW for photovoltaic, storage and radiator mass.

Check notes: Candidate pack passage, compute, power and orbit (research/compute-power-orbit). The quotation (22 words) matched the text retrieved for the candidate pack on 2026-10-28 and again at admission on 2026-10-30, in a fresh retrieval whose SHA-256 equals the pack’s. Matching ignored differences of whitespace, case, quotation marks, dashes and Unicode compatibility forms, so the source’s typography can differ.

Status and meaning

Editorial status. Not reviewed by an editor. An exploratory record that no editor has accepted. This status does not say whether a person has read any linked passage. Each evidence record above shows how it was checked.

Relation. A passage of the document meets the proposition’s criterion. The record documents what the text states, in its register (fiction and satire are labelled); it is not evidence that the proposition is true and implies no influence on or from another text.

Date. Date of publication, as the source gives it.
