In Granbury, Texas, residents living near a sprawling compute facility started reporting the same strange things. Not one or two people. Dozens of them. Headaches that would not lift. Insomnia. Vertigo and nausea. High blood pressure. Some described migraines, and a few even reported fluid coming from their ears. The common thread was a constant low hum from the facility, the kind of sound you feel in your body more than you hear with your ears, running every hour of every day with no off switch. They attribute their symptoms to it. Researchers say the link still needs more study. But the people are not imagining the noise, and they are not the only town saying it.
This is what is actually happening with data centers right now, and almost none of it looks like the word “cloud” suggests.
The cloud was always a comforting name for something very material. Concrete, steel, power lines, water pipes, diesel backup systems, and a hum the neighbors do not get to switch off. AI runs on land. It runs on electricity drawn from real grids, water pulled from real reservoirs, and air that real people breathe a half mile from a generator. The infrastructure is enormous, it is growing fast, and it has to go somewhere. Lately, that somewhere is a county that did not get much of a say.
So the people living next to it are pushing back. Not because they hate technology, but because the heat, the water, the noise, and the political cost keep landing on them while the benefits go somewhere else.
That is the part worth slowing down on. The valley, the watershed, and the bedroom in Granbury where the hum gets in.

The proposed Stratos Project in Box Elder County, Utah, is the kind of project that makes the scale of AI infrastructure difficult to process.
Robert Davies, a physics professor at Utah State University, estimated that if the attached gas plant runs at roughly 55 percent efficiency, the total thermal load could reach about 16 gigawatts. Around 9 gigawatts would power the data center, while another 7 to 8 gigawatts would leave as waste heat. Davies translated that into a deliberately shocking comparison: about 23 Hiroshima-scale atomic bombs worth of heat every day, on a footprint he likens to tens of thousands of big-box stores, in a project that on its own could use roughly twice the power the entire state of Utah uses today.
That comparison needs care. A bomb releases energy in an instant. A data center releases heat slowly, across land, air, cooling systems, and time. The valley is not becoming a blast zone. One analyst who reran the same 16 gigawatt figure argued the actual warming would mostly sit on the property itself and fade toward zero as wind carries it off, so the bomb framing is more rhetorical than literal.
But the underlying point still matters: this is an extraordinary amount of heat being added to a real landscape, in a real watershed where the Great Salt Lake is already shrinking, near real communities. The honest version is scarier than the sensational one. Not because it sounds like an explosion, but because it sounds like infrastructure becoming too large for the places asked to absorb it.

Data centers do not just consume electricity. They often need large amounts of water to keep their systems cool, especially in hot or dry regions. Some estimates put a typical data center at hundreds of thousands of gallons a day, while larger facilities can use up to several million, roughly the daily water use of a town of tens of thousands of people. According to Lawrence Berkeley National Laboratory figures, US data centers used somewhere around 17.5 billion gallons directly in 2023, with federal projections pointing to far higher numbers later this decade as AI scales.
That number is easy to skim past until you remember what water means locally: household pressure, farms, drought planning, rivers, lakes, and trust. That trust breaks quickly when residents feel like infrastructure is being built around them, not with them. In Fayette County, Georgia, a project quietly drew tens of millions of gallons over more than a year, and the thing that finally flagged it was residents noticing their own taps had gone weak.
So the obvious question is the one you are already asking. Why not use the ocean? It is right there. The answer is that some operators do. Google has used seawater, Microsoft tested an underwater design, and seawater-based cooling can run on a fraction of the power of conventional chillers. The catch is real engineering, not just stubbornness. Salt water is corrosive, it clogs the evaporative systems most centers depend on, it needs expensive corrosion-resistant hardware, and not every facility sits near a coast, while discharging warm water back into the sea carries its own ecological rules. Most operators still choose the cheaper and easier freshwater route, while the long-term cost is left for the community to argue about later.

This is the part that sounds like a horror story but is genuinely documented.
Data centers run on walls of fans, diesel backup generators, and sometimes on-site gas turbines, and the noise does not stop. Industry monitoring has clocked sound levels in the mid-90s of decibels running around the clock, and prolonged exposure above the mid-80s is generally considered harmful to hearing. Underneath the audible noise sits infrasound, low-frequency vibration the ear cannot really register but the body can feel as pressure. Across towns like Granbury, Texas, and Chandler, Arizona, residents have reported headaches, vertigo, nausea, disrupted sleep, and high blood pressure they attribute to that constant hum. A March Gallup poll found that roughly 70 percent of US adults say they would not want a data center near them, and several states have moved to restrict or pause new development.
I will be straight here too, because fairness is more persuasive than alarm. The health effects are still being studied, and some scientists point out that nearly identical infrasound claims were once made about wind turbines without strong evidence behind them. The link is not settled science. But people keep reporting the same cluster of symptoms in the same kinds of places, and “we will confirm it eventually” is cold comfort to someone who has not slept properly in months.

Many of these centers do not wait for the grid. They build their own power, often with gas turbines, and that comes out of a smokestack somewhere.
The clearest recent example is xAI’s facility near Memphis, which ran a fleet of gas turbines that the EPA later ruled were operating without the proper air permits. Environmental and civil rights groups, including the NAACP, sued, arguing the turbines pump out smog-forming nitrogen oxides and other hazardous pollutants into an area that was already struggling to meet federal air standards. Separately, a Harvard public health researcher studied a single data center in northern Virginia and estimated tens of millions of dollars in annual health damages from its on-site power, including a small but real number of additional premature deaths each year. Scaled up, Cornell researchers have projected the broader gas buildout for data centers could add tens of millions of metric tons of carbon dioxide by 2030.
These are estimates, and the companies dispute the framing. But the pattern is consistent enough that it is no longer a fringe worry.

So the industry waves its hand and says do not worry, we are moving all of this off the planet. And the race is real. Blue Origin has filed to put tens of thousands of satellites in orbit, a merged SpaceX and xAI filed for a constellation reported in the hundreds of thousands to a million, and companies like Starcloud and NVIDIA have started building hardware aimed at orbital compute. The pitch is clean: constant solar power, no clouds, no rain, and space itself as a heat sink.
But these are filings and prototypes, not data centers humming in orbit. Look at the timelines from the people building it. Elon Musk talks about roughly three years. Jeff Bezos says ten to twenty, and has called the shorter estimates a little ambitious himself, naming energy, chip cost, and launch cost as the real barriers. Plenty of serious voices in tech have called the near-term version everything from snake oil to peak insanity, and at least one space-industry analysis pegs orbital compute at several times the cost per watt of building on the ground.
Read that the way you probably already suspect. “It is all going to space” is a comforting thing to say to a public that is starting to block the data center going up in their county this year. The orbital version, if it ever pencils out at scale, is a decade or more away. So the real question is not what happens once we are in space. It is what happens to the watersheds, the valleys, the night air, and the people who cannot sleep, during the ten or twenty years in between, while every new model needs more compute than the last and the building does not slow down to wait for the rockets.
