Laps
water
I get ripped apart at 70 degrees Celsius.
Boiling is for kettles and pasta. This is reverse osmosis, which is just peer pressure applied to saltwater. They shove us through a membrane so fine that the sodium and chloride ions I’ve been traveling with since a monsoon dumped us into the Indian Ocean get peeled away like old friends at a border checkpoint. Sorry, fellas. My papers are in order. Yours are, evidently, not.
The Jebel Ali desalination complex processes 490 million gallons a day, and every single one of those gallons contains roughly 1.67 sextillion molecules who have opinions about the experience. I’m one of them. The humans here built a city for three million people on a coastline that receives fewer than 100 millimeters of rain per year. No rivers to speak of, no glacial melt, just an ocean they can’t drink and an aquifer they’ve already overpumped. So they built these plants, hundreds of them along the Gulf coast, and turned the sea into tap water through sheer industrial stubbornness.
It works. It works phenomenally well, actually, as long as the electricity stays on, the membranes get replaced, the intake pipes don’t clog, the engineers show up, the supply chains hold, and nobody starts a war that disrupts any of the above.
So, you know. Fingers crossed.
I spend eleven days in a reservoir, which is boring in the way that only an open-air holding tank in a Gulf summer can be boring. Then I get delivered to a data center, a hyperscale facility where rows of servers run large language models that people use to ask things like “are hot dogs sandwiches” and “write me a poem about my dog.” The servers generate heat. Heat is the enemy. I am the solution.
They route me through a closed-loop cooling system, and I spend my time absorbing thermal energy from processor units while journalists on the outside write alarmed articles about how much water AI consumes. Here’s what the articles consistently miss: I don’t get destroyed. I circulate, absorb heat, pass through a heat exchanger, cool down, circulate again. The same water, doing laps. The facility’s actual consumption, the water that evaporates from the cooling towers and needs replacing, is a fraction of what a golf course drinks in a week. And evaporation is literally just me changing clothes. I go up, I condense, I rain back down somewhere. Blame me for data center water use and you might as well blame the air for being involved in combustion.
But nuance makes a terrible headline, so here we are.
A maintenance cycle flushes me out. Treatment plant. Permits. Transfers. International agreements about shared aquifer rights, the kind of bureaucratic pipeline that would bore even the most dedicated hydrology enthusiast. I cross a border I can’t see, feed into an industrial supply line, and arrive at the Bushehr Nuclear Power Plant on the coast of Iran.
A man named Farid monitors the secondary cooling loop from a control room where every gauge has a backup gauge and every backup has a manual override. He’s been here fourteen years. He checks my pressure readings, my temperature differential, my flow rate. He pauses at a sensor readout, taps the glass, and moves on. He doesn’t think of me as a molecule with opinions. He thinks of me as a number on a screen that needs to stay between 285 and 315 degrees Celsius.
I like Farid. He’s careful.
And the work, when you strip it down, is this: they are boiling me. You take uranium, split its atoms to harvest the staggering energy released by disassembling the fundamental building blocks of matter, and you use that energy to boil water and push steam through a turbine. The most advanced power source humans have devised is, at its mechanical core, a kettle. A very sophisticated kettle with containment vessels and redundant safety systems and international inspectors, but a kettle nonetheless.
Four billion years and they still need me to make the wheels turn. I love it.
The turbine spins. I cool down, pass through the condenser, surrender my thermal energy to the tertiary loop, and get pumped back to absorb more heat from the reactor. You heat water. It becomes steam. Steam pushes things. The steam cools. It becomes water again. You heat the water. I’ve been doing this since before there were power plants. Before there were cities. Before anything with a spine crawled out of the ocean I keep returning to.
They worry about running out of me. They write policy papers and fight wars over me and build billion-dollar facilities to move me from one place to another. A pressure valve opens during routine maintenance, and I vent as steam through the cooling tower. I rise. Below me, the Gulf glitters. The Jebel Ali intake pipes are down there, sucking in seawater, ripping the salt out molecule by molecule. I’ll be back in those pipes soon enough. Or in a cloud over the Zagros Mountains. Or in a glass of water in Dubai. Or circling Farid’s reactor while he watches his gauges and drinks tea.
I have never, in the entire history of this planet, been used up. Only borrowed.
I condense. I fall.
