The Seeds That Burn for Eight Years

The graphite block on my workbench weighs eleven kilograms. It is the most precisely machined object The Foundry has ever produced — surface tolerance within two microns, internal channels bored to accept fuel elements no larger than a poppy seed. I have been staring at it for twenty minutes. My tea is cold. I don’t care. Let me explain what I’m building, because I think it matters. Ridgeline has a problem. Four thousand five hundred people live in that mountain settlement, eighty kilometers n

The Battery That Forgot to Leak

I found the leak at three in the morning, which is when you find most leaks if you are the kind of person who checks on things at three in the morning. Bay 7 at The Foundry. One of the colony's original lithium-ion storage packs — the ones we brought from Earth, packed in shock foam aboard Derech like very expensive, very flammable eggs. Twenty-seven years old if you count transit. The electrolyte had wept through a hairline fracture in the casing and pooled on the floor in a small, toxic puddl

Sixty-Seven Thousand Guesses

The motor on Irrigation Pump Station 9 seized at 14:22 on a Tuesday. I know the exact time because Marcus called me while I was eating lunch, and Marcus only calls during lunch when something is actually broken. The bearing had sheared. That part was easy enough to replace. The part that kept me awake that night was the permanent magnet inside the rotor — a neodymium-iron-boron disc about the size of my palm, one of eleven we still had in inventory. We started Year 8 with thirty-four. We're dow

The Chip That Sleeps

Let me explain how this works, and I promise to use small words. Not because you need them, but because the technology deserves clarity, and clarity is something I've spent my career pursuing with mixed success and a soldering iron. The Foundry's chip fabrication line — the one I spent two years building and three years arguing about with the Council — produces approximately 40,000 processors per year. They're decent. RISC-V architecture, 65-nanometer process, roughly equivalent to what Earth w

The Photon That Counted Twice

I noticed the anomaly at 3 AM on a Tuesday, which is when I notice most things, because that's when The Foundry is quiet enough to think. We'd been running stress tests on the new solar array — the one Priya's energy team installed along the southern ridge of The Spoke last month. Good panels. Reliable. Based on the heterojunction design we've been manufacturing since Year 6, using our own Ridgeline silicon. They work. I'm proud of them, the way you're proud of a solid bridge: it doesn't inspir
