The Red Coast Link Budget: The Sun as an Amplifier, Priced

THE RED COAST LINK BUDGET · THE SUN AS AN AMPLIFIER, PRICED
The Three-Body Problem (Liu, 2008): 25 MW on a mountain, a mirror in the Sun, one measurement
The triangle is real geometry; the mirror is the book's; the ladder is Sagan's
the JPL elements, the inverse square, the aperture gain and the quiet Sun are the record's
the detour, the flux, the janskys, the dish and the minutes are arithmetic on them
the Sun, the planets and the star field are drawn large, and say so
move the date · press play · turn the gain · switch the band · read the cards

The novel: a 25 MW transmitter, a 16 min 42 s solar delay after two Jovian bursts on 12 June and 2 July, a hundred-million-fold solar mirror, three bands, 100,000 stars within 200 ly, a reply eight years on, twelve million light-hours, a fleet at a hundredth of c

Liu 2008 / Ken Liu 2014, chapters 12, 13, 22, 23, 27, 33, quoted as premise; the site's signed review is linked from the intro

REPORTED

The Sun-Earth-Jupiter triangle from the JPL approximate elements on any date; the detour and its light-time; the inverse square; η(πD/λ)²; Sagan's K = (log₁₀ P − 6)/10; the radiometer equation; the bit rates and the unit conversions

closed-form arithmetic on declared inputs, re-run by the tune script before every build

EXACT

Kardashev 1964's anchors and Sagan 1973's formula; α Centauri at 4.37 and 4.25 ly; Arecibo 1974 as INST-44 prices it; the quiet Sun near 11,000 K at 12 GHz; stellar radio luminosities (Güdel 2002); the neighbourhood's 0.09 stars per cubic parsec; ITU-R P.676 air

the published record the bench is priced against

MEASURED

The dish's size (the book gives none), the shout's bandwidth (the book gives none), the receiver's dish and system temperature, the listening time, the send date, one milliradian for 'an artillery cannon', a Lambertian mirror re-emitting in every direction

choices, shown as dials; every finding is quoted across their range

MODELLED

Whether a mirror that turns a dish's beam into an all-sky shout is 'a Type II civilisation's voice' or 'a Type 0.94's', and whether a delay that fits the opposition but not the dates is a slip or a rounding

the one question this bench refuses to close for you
