Chapter 6: The First Winding

The coastal site was not what Maren had expected, and she was not sure what she had expected, but it wasn't this. The decommissioned agricultural station was a cluster of low stone buildings on a hillside above the Adriatic, overlooking a bay that would have been beautiful if she had been in any state to notice beauty. The buildings had walls and roofs and not much else. The water supply was a hand pump connected to a well that someone had tested two weeks ago and declared "adequate," which was the kind of word that meant something different to an engineer than to a person who wanted to wash her face.

They arrived in the late afternoon. Thin November light that turned the stone walls gold and showed every crack. The trucks pulled into what had once been a courtyard and was now a square of packed earth with weeds growing through the cracks. Someone had set up a folding table with a camp stove and a pot of coffee, and Maren loved that person, whoever they were, without needing to know their name.

The flywheel came off the flatbed with the help of eight people and a set of ramps that flexed in ways that made Maren's knees want to leave. It was heavy. Someone's foot slipped on the ramp. Someone shouted "left, LEFT." They set it down in the largest of the stone buildings, which had been a drying barn and still smelled like old hay and dust and the sweetness of grain that has been stored too long.

Davorka walked the site that evening with Maren and a structural engineer named Luka from Velden. He ran his hand along a foundation wall and said, "This one's carrying more than it knows." He pointed at foundations and corners and drainage lines and said things like "this will hold" and "this won't hold but it will by March" and "this is interesting." When Luka said something was interesting, it meant he didn't know what it was and was planning to find out at five in the morning.

The first night they slept in the buildings on cots and sleeping bags. There were no phosphorescent panels yet; Davorka had ordered them but they hadn't arrived. The darkness after sunset was total in a way Maren had not experienced since a childhood camping trip. She couldn't see her hand. She lay on her cot and heard the building settle, the wind off the bay, three other people breathing, and the distant sound of the sea.

She did not sleep well. Her back hurt from the drive. Her hands smelled like metal from the flywheel. The cot was too short by about ten centimeters, which she discovered at two in the morning when her feet hit the crossbar and she woke up thinking she'd walked into something.

The assembly took six days.

Davorka had specifications. Luka had structural intuition. A woman named Petra, who had been a mechanical engineer before she'd read Davorka's proposal and quit her job in Zagreb, had the technical knowledge to translate specifications into bolted reality. The rest of them had hands and a willingness to use them, which turned out to be what most of the work required.

The cranking station was simpler than Maren had imagined and more complicated than it looked. The core was the flywheel: a steel disc, ninety centimeters across, mounted on bearings in a housing that Petra anchored to the concrete floor of the drying barn with expansion bolts. The crank handles attached through a three-stage gear train that stepped up slow human effort into fast rotational speed. The gears were the part that mattered most.

"The gears are the soul of the thing," Petra said on the third day, while she was filing a tooth profile that didn't meet her standards. She had a file in one hand and the gear blank clamped to a workbench that they'd built from scrap lumber and a stone they'd found behind the building. "Every tooth that's off by a tenth of a millimeter is someone's effort gone to heat."

"How precise do they need to be?" Maren asked.

"More precise than I can get with a file and a prayer. But this is what we have, so this is what we'll use." She blew metal dust off the tooth. "The first machine is always terrible. The first machine is the one that lets you build the second machine, and the second machine is the one that starts to work. That's how it goes."

Maren watched her file for a moment, then went to help unload the bearings.

The gear train connected to an output shaft that could be coupled to different loads. For now, the only load was the flywheel itself; the station's job was to spin the flywheel up and store kinetic energy that could be released in controlled bursts through a clutch mechanism. Later, Petra said, they would add a gravity battery: a stone counterweight on a chain, wound up through the cranking and descending slowly through a second gear train to power the water pump. Later, they would add a spring bank for household tools. Later, they would add a lot of things. For now, the flywheel.

They ate their meals outside when the weather held, camp-stove food that was better than it had any right to be because one of the twenty-nine turned out to have been a cook before she'd been a biologist. Bean stew, mostly, with bread from the village down the hill. Maren ate with her hands raw from bolting and her knees cold from kneeling on stone, and the food was warm and unremarkable and she was grateful for all of it.

The bearings were the problem. The flywheel needed to spin freely once it was wound, which meant the bearings had to be good, which meant they needed machining that the camp didn't have. Petra had brought two sets: one fabricated in Ljubljana with the cranking station, and one she'd made herself at Velden, which she described as "functional but humiliating." They installed the Ljubljana set. The spare went into storage.

"When the Ljubljana bearings wear out," Petra said, "we'll need to make our own. That means a lathe. That means a forge to make lathe components. That means solving three problems before we solve the one we actually have."

"Recursive infrastructure," Maren said.

"Exactly. Everything you need requires something you don't have yet. The trick is finding the longest chain you can build from what you do have and not dying of frustration before it reaches the thing you need."

Davorka listened to these conversations from the corner of the barn where she'd set up a desk made of a door laid across two crates. She made notes. She adjusted specifications. She did not hover. This was one of the things Maren noticed about her during the assembly: Davorka gave people the parameters and then let them solve the problems within those parameters, and she intervened only when the solution was about to violate a constraint she hadn't communicated. Once, she stopped Luka from mounting a secondary support bracket on a wall that she said would need to be removed for the gravity battery installation. He asked how she knew. She said, "Because I've been planning this building's layout for three years and that wall is in the way of the chain channel." He moved the bracket. She went back to her desk.

They wound the flywheel for the first time on a Wednesday. Maren remembered it was a Wednesday because Luka had been keeping a calendar on the barn wall by scratching marks in the stone with a nail, and she'd counted them that morning while waiting for Petra to finish her final bearing alignment. Six marks since arrival. Wednesday.

It was not a ceremony. Nobody gave a speech. Davorka did not believe in speeches at moments when the thing itself was the speech.

Petra checked the gear train one final time. She ran her hands along the tooth profiles the way she always did, which Maren had realized was not just quality control but a kind of listening; Petra could feel misalignment through her fingertips before any instrument would detect it. She nodded.

"It's as good as it's going to get," she said. "Who wants to go first?"

Nobody moved. Twenty-nine people stood in the drying barn that smelled like old hay and new metal oil, and nobody moved.

Davorka walked to the crank. Her knees cracked when she bent to adjust the handle height. She gripped the handles and looked at the room.

She pulled.

The crank resisted, then gave. The gear train engaged with a sound that Maren would hear in her sleep for weeks: a deep, mechanical click as the first tooth caught the second, a vibration that traveled through the frame and into the floor and up through the soles of her boots. The gears turned. The flywheel began to move.

It was slow. Davorka cranked with a steady, unhurried rhythm, and the flywheel turned, and the gears meshed, and the teeth that Petra had filed by hand did their job, and the steel disc began, imperceptibly, to hum.

The hum was the first new sound. Maren heard it rise out of nothing, a low tone that lived below the click of the gears, below the creak of the crank handles, below Davorka's breathing. It was the sound of energy being stored.

Somewhere outside, a barn door that hadn't been latched properly banged once in the wind and then was still.

Davorka cranked for five minutes. Then she stepped back, rubbing her hands, and said, "Next."

Luka went next. Then Petra. Then a young man named Emil who had been a physiotherapy student and who attacked the crank with an enthusiasm that Petra immediately corrected ("Slower. The gears don't care about your ego. Sixty RPM. Count it."). Then a woman Maren didn't know well, who cranked for ten minutes and then sat on a crate and cried.

Maren went seventh. She gripped the handles. They were warm from the six people who'd held them before her. The metal had the faint oil smell of machined surfaces, and underneath it something else, something biological: the residual heat of hands. Six people's hands.

She pulled. The resistance was firm and even, the work of a well-designed gear ratio translating her effort into something the flywheel could use. She felt it in her shoulders first, then her back. The rhythm settled in after a minute. The crank turned. The gears caught. The flywheel hummed, louder now, fed by seven people's effort, and the hum filled the barn with a sound that hadn't existed in this building until this moment.

She cranked for ten minutes. Her breathing deepened. Her heart rate rose. Her muscles warmed and settled into a rhythm that felt, after a few minutes, less like effort and more like a conversation between her body and the machine.

When she stepped back, the flywheel was spinning at a speed she could hear but not see. The hum had become a tone, a sustained note that resonated in the stone walls and in her chest and in the wood of the crates and in the concrete floor. It was not loud. It was present. It was not loud.

That night, the flywheel sang.

The bearings were not perfect. Petra had said they wouldn't be. At certain speeds the vibration found a frequency that the housing amplified, and the flywheel produced a low, steady, musical hum that carried through the stone walls and into the November air. You could hear it from outside the barn. You could hear it from the courtyard. If you were lying on a cot in one of the sleeping buildings, you could feel it in the frame, a vibration so faint that you weren't sure if it was the machine or your own pulse.

Maren lay on her cot (still too short; she had stuffed a folded jacket under the crossbar, which was an improvement in the way that bad solutions to real problems are improvements) and listened. Around her, people were settling in. Someone was snoring in the room next door. Outside, the wind came off the bay and moved through the buildings with the whistle of air finding gaps it hadn't found before. And underneath everything, the flywheel.

It was not ticking. That was a later problem. For now it was just a hum.

But it was there.

Maren listened to it. She thought about Tomas, standing in the loading area with his hands in his pockets. She thought about Josip's figs, which were gone. She thought about the chipped cup, which was in her crate, wrapped in a dish towel, waiting for a shelf that didn't exist yet.

The flywheel hummed. The wind came off the sea. Somewhere in the building, Petra was still awake, doing something that involved a file and a headlamp and quiet swearing. Someone else was making tea on the camp stove; she could smell it through the wall.

Her back hurt. Her hands smelled like metal. The cot was too short. She pulled the sleeping bag up to her chin and listened to the hum until she didn't.
