Drawing on economics and accounting, Stewart gives his settings a standard cargo unit scaled far beyond a present-day twenty-foot equivalent unit. Shared dimensions let freighters, heavy shuttles, holds, and orbital infrastructure be designed around loads whose mass and volume readers can compare. Water may itself be frequent bulk cargo, making the logistical scale tangible rather than an unspecified number of crates. The same passage adds a useful engineering reversal: spacecraft usually struggle to reject heat, but a ship with its main reactors offline may instead lack enough heat to keep operating safely.

Cargo standards and thermal budgets make fleet scale concrete
Standard cargo units connect ship capacity with infrastructure and economics, while thermal balance can fail through too little heat as well as too much.
