Warming up…
Follow a drop of water and a speck of heat on the journey from a humming server… all the way to a strawberry in January.
Start the journeyYou're about to follow them everywhere a data center's leftover warmth goes. Say hello first.
Calm, steady, and proud to go in circles all day — on purpose. Demi is the courier. She carries heat from place to place and never, ever quits her route.
Warm, fast, and — let's be honest — a lot. Every time a computer thinks a thought, another Jimmy is born. He just wants one thing: a job to do instead of being thrown away.
Demi represents a drop of water moving through a sealed pipe loop. Jimmy represents a joule — a single unit of heat energy. Between them, they carry a data center's leftover warmth next door to a greenhouse, and out comes food. Everything ahead is real, standard equipment: district heating and commercial greenhouses have each been built this way for decades. Intelligent Harvest simply joins the two.
A data center turns almost all of the electricity it draws into heat — that's basic physics, not waste in the bad sense. The servers run at roughly 35–50°C: warm, not scorching. That warmth is real, usable energy. There is simply an enormous amount of it, produced around the clock, every day of the year.
Roughly two-thirds of the energy humanity produces ends up rejected as low-grade waste heat — the largest untapped energy source on the planet. Most data-center heat has simply been vented into the air through cooling towers or chillers. Not because the heat is worthless, but because no one had built it somewhere useful to go.
Instead of venting it, a sealed loop captures the heat from the data center's existing cooling system and carries it to the energy center — a small plant room beside the building. The loop only collects warmth; it never touches the servers themselves. This approach is cooling-agnostic: it works with whatever cooling the data center already uses.
High-fives: 0
Two separate water circuits meet at a heat exchanger but never mix. Heat passes through a thin wall from one side to the other; each loop keeps its own water. This is the firewall of the whole system — the only thing that ever crosses into the greenhouse side is warmth. Nothing that touched the data center ever reaches a plant.
A buffer tank stores warm water so a steady, around-the-clock heat supply can meet a greenhouse's changing, hour-by-hour demand. On the coldest nights, a small, optional heat pump can nudge the water a little warmer — but it's a helper for edge cases, not the main act. The system runs on the heat that already exists.
Warm water flows through hydronic heating pipes along the growing beds — the same idea as a home radiator — delivering gentle warmth tuned to roughly 28°C at the beds, then cooling as it gives up its heat. The plants drink their own separate, clean irrigation water; Demi only ever brings the warmth. "Low-grade" heat isn't a flaw here — it's exactly the temperature a winter greenhouse wants.
After giving up its heat, the now-cooler water (about 28°C) loops back to be re-warmed — around the clock, the same sealed water, indefinitely. As a bonus, returning cooler water can lighten the data center's own cooling job a little. Nothing is consumed but the warmth, and even that came from energy that was already being spent.
Real strawberries in January. Year-round greenhouse jobs. A place to bring the kids. The same building everyone was fighting about now feeds the neighborhood — using only the warmth it was already throwing away.
Everything Demi and Jimmy just walked through is standard, proven equipment — district heating and commercial greenhouses have each been built this way for decades. Intelligent Harvest simply joins the two, next door to each other.
Demi and Jimmy keep it friendly. The research brief keeps it rigorous — the mechanism, the proof, the graveyard of farms that failed, and why we’re built to do the opposite. In the open, no NDA required.
