An Underwater Data Center in San Francisco Bay? Regulators Say Not So Fast | EUROtoday

CommunityOcean isn’t alone in its ambitions. Founded in 2021, US-based Subsea Cloud operates about 13,500 pc servers in unspecified underwater places in Southeast Asia to serve shoppers in AI and gaming, says the startup’s founder and CEO, Maxie Reynolds. “It’s a nascent market,” she says. “But it’s currently the only one that can handle the current and projected loads in a sustainable way.”

Subsea secured a allow for every website and makes use of remotely operated robots for upkeep, in response to Reynolds. It plans to fireside up its first underwater GPUs subsequent yr and likewise is contemplating personal websites, which Reynolds says would ease allowing complexity. Subsea claims it isn’t considerably growing water temperature, although it hasn’t revealed unbiased critiques.

CommunityOcean additionally believes it would trigger negligible heating. “Our modeling shows a 2-degree Fahrenheit change over an 8-square-fot area, or a 0.004-degree Fahrenheit change over the surface of the body” of water, Mendel says. He attracts confidence from Microsoft’s discovering that water just a few meters downstream from its testing warmed solely barely.

Protected Bay

Bay Area initiatives can enhance water temperatures by not more than 4 levels Fahrenheit at any time or place, in response to Mumley, the ex-water board official. But two biologists who spoke to WIRED say any enhance is regarding to them as a result of it may incubate dangerous algae and entice invasive species.

Shaolei Ren, a University of California, Riverside, affiliate professor {of electrical} and pc engineering who’s finding out the environmental influence of AI, compares plans for an underwater knowledge middle of CommunityOcean’s introduced capability, when working totally utilized, to working about 300 bed room house heaters. (Mendel disputes the priority, citing Project Natick’s apparently minimal influence.) Just a few years in the past, a challenge that proposed utilizing San Francisco Bay water to chill an information middle on land didn’t win approval after public issues have been voiced, together with about temperatures.

The San Francisco Bay is on common round a dozen ft deep, with salty Pacific Ocean water flowing in from beneath the Golden Gate Bridge mixing with contemporary runoff from an enormous swath of Northern California. Experts say it isn’t clear whether or not any location within the expanse could be appropriate for greater than a tiny demonstration between its muddy, shallow, salty, and turbulent components.

Further, securing permits might require proving to not less than 9 regulatory our bodies and several other crucial nonprofits {that a} knowledge middle could be worthwhile, in response to spokespeople for the businesses and 5 consultants within the bay’s politics. For occasion, beneath the legislation administered by the Conservation and Development Commission, a challenge’s public profit should “clearly exceed” the detriment, and builders should present there’s no appropriate location on land.

Other businesses take into account waste emissions and hurt to the area’s handful of endangered fish and birds (together with the notorious delta smelt). Even a brief challenge requires signoff from the US Army Corps of Engineers, which critiques obstruction to ship and boat visitors, and the water board. “For example, temporarily placing a large structure in an eelgrass bed could have lingering effects on the eelgrass, which is a critical habitat for certain fish,” the water board’s Lichten says.

CommunityOcean’s Kim tells WIRED that the corporate is cognizant of the issues and is avoiding delicate habitats. His cofounder Mendel says that they did contact one of many area’s regulators. In March, CommunityOcean spoke to an unspecified US Coast Guard consultant about testing on the backside of the bay and pumping in seawater as a coolant. The firm later shifted to the present near-surface plans that don’t contain pumping. (A Coast Guard spokesperson declined to remark with out extra readability on whom CommunityOcean allegedly contacted.)

For everlasting installations, Kim and Mendel say they’re eyeing different US and abroad places, which they declined to call, and that they’re participating with the related regulators.

Mendel insists the “SF Bay” take a look at introduced final month will transfer ahead—and shortly. “We’re still building the vessel,” he says. A group of marine scientists will probably be holding their thermometers shut.
