Most electronics endure a debilitating aquaphobia. At the ­littlest­ spillage—heaven forbid Dorothy’s bucket—of water, our depraved widgets shriek and soften.

Microsoft, it could appear, missed the memo. Last June, the corporate put in a smallish information middle on a patch of seabed simply off the coast of Scotland’s Orkney Islands; round it, roughly 933,333 bucketfuls of brine flow into each hour. As David Wolpert, who research the thermodynamics of computing methods, wrote in a latest weblog put up for Scientific American, “Many people have impugned the rationality.”

The concept to submerge 864 servers in saltwater was, in truth, fairly rational, the results of a five-year analysis undertaking led by future-proofing engineers. Errant liquid may fritz your telephone, however the slyer, far deadlier killer of expertise is the opposing elemental power, hearth. Nearly each system failure within the historical past of computer systems has been brought on by overheating. As diodes and transistors work tougher and get hotter, their susceptibility to degradation intensifies exponentially. Localized, it’s the nice and cozy iPhone in your cheek or a wheezing laptop computer providing you with upper-leg sweats. At scale, it’s Outlook rendered inoperable by distant server meltdown for 16 excruciating hours—which occurred in 2013.

Servers underlie the networked world, continually refreshing the cloud with droplets of information, and so they’re as precious as they’re susceptible. Housed by the tons of, and sometimes the hundreds, in hundreds of thousands of information facilities throughout the United States, they price billions yearly to construct and shield. The most vital quantity, nevertheless, could be a single-digit one: Running these machines, and subsequently cooling them, blows by an estimated 5 p.c of whole vitality use within the nation. Without that energy, the cloud burns up and you may’t even fact-check these stats on Google (an operation that prices some server, someplace, a kilojoule of vitality).

Savings of even a couple of levels Celsius can considerably prolong the lifespan of digital elements; Microsoft reviews that, on the ocean flooring 117 ft down, its racks keep 10 levels cooler than their land-based counterparts. Half a yr after deployment, “the equipment is happy,” says Ben Cutler, the undertaking’s supervisor. (The solely exceptions are a number of the facility’s ­outward-facing cameras, currently blinded by algal muck.)

Another Microsoft worker refers back to the effort as “kind of a far-out idea.” But the reality is, most hyperscalers investing in superpowered cloud server farms, from Amazon to Alibaba, see in nature a dependable protection in opposition to ever extra refined, heat-spewing circuits. Google’s first information middle, inbuilt 2006, sits on the temperate banks of Oregon’s Columbia River. In 2013, Facebook opened a warehouse in northern Sweden, the place winters common –20 levels Celsius. The information firm Green Mountain buried its huge DC1-­Stavenger middle inside a Norwegian mountain; pristine, near-freezing water from a fjord, guided by gravity, flows by the cooling system. What Tim Cook has been calling the “data-­industrial complex” will rely, if it’s to sustainably broaden to the farthest reaches, on a nonindustrial technique of survival.

Underwater facilities could characterize the following section, a reverse evolution from land to sea. It’s by no means been arduous, in any case, to waterproof massive gear—consider submarines, which get extra watertight as they dive deeper and strain will increase. That’s actually all Microsoft is doing, swapping out the payloads of individuals for packets of information and hooking up the trucklong pod to umbilical wiring.

Nonetheless, Cutler says, the idea “catches people’s imagination.” He receives enthusiastic emails about his sunken middle on a regular basis, together with one from a person who builds residential swimming swimming pools. “He was like, you guys could provide the heating for the pools I install!” Cutler says. When pressed on the feasibility of the enterprise mannequin, Cutler provides: “We have not studied this.”

Others have. IBM maintains a knowledge middle outdoors of Zurich that actually does warmth a public swimming pool on the town, and the Dutch startup Nerdalize will erect a mini inexperienced information middle in your house with guarantees of a heat bathe and toasty front room. Hyperlocal servers, a part of a transfer towards so-called edge computing, not solely present recyclable vitality but in addition convey the community nearer to you, making your connection speeds sooner. Microsoft envisions sea-based amenities just like the one in Scotland serving population-dense coastal cities all around the world.

“I’m not a philosopher, I’m an engineer,” Cutler says, declining to supply any quasipoetic contemplations on the upcoming fusion of nature and machine. Still, he does notice the climate on the morning his staff hauled the servers out to sea. It was foggy, after every week of clear skies and vibrant solar—as if the literal cloud, reifying the digital, had been peering into the shimmering, unknown depths.
