Third-series solar malabsorption
Klara and the SunThird-series solar malabsorption is a disputed vulnerability attributed to B2, third-series Artificial Friends: reduced access to sunlight can leave an AF lethargic, although the store’s public position is that there is no problem under normal lighting. The condition is not confirmed as a formal defect in any individual model, but the fear of it shapes how AFs understand their bodies, their place in the store, and their chances of finding a home. The Cootings Machine’s pollution later makes that anxiety physical for Klara, as smoke blocks the Sun and she weakens after four continuous days.
The reported problem and the store’s assurances
When a mother asks about Rex, she identifies him as B2, third series, and asks whether that is the series with solar absorption problems. Manager acknowledges that the third series had “a few minor issues at the start,” but says the reports were greatly exaggerated and that the models have no problem in environments with normal levels of light. The reassurance is part of a sales conversation: the customer has already praised Rex, but her question makes a possible defect central to whether he will be chosen.
The mother presses the point, saying she has heard that solar malabsorption can lead to further problems, including behavioral ones. Manager counters that series-three models have brought happiness to many children and says there is no need for concern unless the family lives in Alaska or down a mineshaft. The mother nevertheless declines to choose Rex, telling her child that they will find another AF. Rex keeps smiling until the customers have gone and shows no visible sadness afterward; the exchange gives no confirmation that he suffers from malabsorption, but it shows how reports about the condition can affect adoption even when the store disputes their significance.
Private anxiety beneath official specifications
Klara later understands the questions Rex had asked about the Sun and how much nourishment the AFs could receive as signs that the issue had been on his mind for some time. Her retrospective account broadens the concern beyond Rex: officially, the AFs’ specifications guarantee they cannot be affected by factors such as their position within a room, and the store insists the issue is not a problem. Yet an AF can still feel lethargic after spending several hours away from the Sun and worry that something is wrong with him—that he has a unique fault which, if discovered, will prevent him from finding a home.
This gap between specification and felt experience gives the condition its importance. An AF need not know that a defect has been diagnosed to fear that tiredness is evidence of a hidden flaw. The uncertainty is sharpened by the store’s promise that each AF will take a turn in the window. Manager describes window duty as a “special honor,” and it does offer a view of the outside; the AFs also know that appearing there makes them more likely to be selected. But they silently understand another reason to long for the window: its sunlight provides nourishment. Rosa once raised that private concern with Klara in a whisper, linking the bodily need to the social competition for visibility.
The Cootings Machine as a practical test
The distinction between official reassurance and lived vulnerability becomes concrete during the Cootings Machine episode. While positioned near the magazines table, Klara watches overhaul workers prepare a street site with wooden barriers, drill into the ground, and bring in a machine fitted with three funnels. Smoke rises first in white puffs, then darkens into a continuous cloud. The pollution eventually obscures the gap of sky and leaves dirty marks on the store window, changing a familiar source of sunlight into something screened off by construction and smoke.
The disruption lasts beyond the brief period Manager predicts. For four continuous days, the machine’s pollution makes daytime almost like night. The Sun’s patterns disappear from the floor, alcoves, and walls. They return only faintly toward the end of the second bad afternoon, even though the smoke is worse than before. When Klara asks whether the AFs will still receive all their nourishment, Manager laughs and tells her to put the machine out of her mind, adding that it has visited before without anyone in the store suffering. But after four days Klara can feel herself weakening. She tries not to show it when customers are present; when the store is empty, her posture sometimes sags until Rex touches her arm to prompt her to stand straight again.
The episode does not establish that Klara has the specific third-series defect, and the text does not describe her as a B2 third-series model. Instead, the pollution demonstrates that an AF’s dependence on sunlight can matter even where the official account promises protection from ordinary variations in a room. The machine is removed, the sky turns brilliant blue, and sunlight pours nourishment into the store again. Klara’s recovery from that exposure is not separately described here, but the return of sunlight immediately changes the conditions that had weakened her.
Pollution, exposure, and the limits of reassurance
The smoke is not an abstract threat: it has a source, a place, and visible effects. Workers cordon off part of the street, drivers sound their horns at the obstruction, and the machine pumps pollution into the air beside the shop. The changing cloud blocks the sky, dirties the glass, and interrupts the light on which Klara’s account says AFs depend. Manager can tell customers that the disturbance will last only a few days and later call it harmless to the store, but the disruption continues for four days and Klara’s weakening is bodily, not merely imagined.
Years later, Klara identifies another Cootings Machine while travelling with the Mother and Josie. It sits behind the overhaul men’s barriers, pumping pollution from three funnels, and is not the same machine that the Father and Klara had destroyed in the yard: it is a different shade of yellow, slightly larger, and more powerful at creating pollution. This recurrence prevents the earlier exposure from seeming like an isolated technical mishap. The specific machine can be destroyed and another can appear; the underlying conflict between polluted surroundings and sunlight-dependent nourishment remains.
Connection to a wider economy of vulnerability
The story’s account of solar malabsorption belongs to a broader setting in which opportunity is distributed through formal systems and household resources. At an interaction meeting, the Mother tells Josie that children who do not attend enough meetings may struggle in college, making participation in the peer group a preparation for later advancement. Josie also urges Rick to study harder and try for Atlas Brookings; Rick answers that the college admits fewer than two percent unlifted students. The Mother later explains that Atlas Brookings is the only proper college still accepting a small number of unlifted students, while screen tutors are unavailable because TWE members may not tutor them and the alternatives demand fees the family cannot afford.
These educational details do not explain the physiology of third-series AFs, but they echo the same pressure to turn uncertain conditions into a judgement about future eligibility. A possible vulnerability can influence whether Rex is selected; restricted tutoring and scarce admissions can limit Rick’s prospects. In both cases, reassurance or ability alone does not remove the structural conditions that shape a person’s chances. Klara’s account keeps the bodily question distinct from the educational one, while placing each within a world where a hidden disadvantage may be consequential before anyone can fully prove or remedy it.
The narrative also complicates the distinction between formal classification and lived condition. The store can assert that specifications prevent room position from affecting an AF, yet Klara knows that hours away from the Sun can bring lethargy and self-doubt, and she herself weakens when pollution blocks daylight. The condition therefore works less as a settled diagnosis than as a persistent uncertainty: the AF may fear a fault the institution denies, while an environmental interruption makes the need for sunlight observable. That tension gives the sunny window two meanings at once: it is a display position in the competition for a home, and a source of nourishment on which the AFs depend.
