The company behind the plan has already begun pilot testing in preparation for a 100-home trial run this year.The “distributed data center solution” announced by the San Francisco startup SPAN would deploy thousands of XFRA nodes that contain liquid-cooled Nvidia RTX Pro 6000 Blackwell Server Edition GPUs operating with minimal noise, according to apress release.By harnessing excess power capacity among US households, SPAN aims to quickly expand the available compute for AI workloads without thecosts and delaysassociated with trying to build warehouse-sized data centers.“Data centers are loud, ugly, and often drive up local electricity bills,” said Chris Lander, vice president of XFRA at SPAN, in correspondence with Ars. “[This] is quiet, discreet, and makes energy more affordable for the host and community.”SPAN’s approach could avoid thesignificant land useandwater consumption issuesthat come with huge data center projects, which may help sidestep growing communityoppositionto such developments. In aCNBCinterview, SPAN also claimed it could install 8,000 XFRA units at a cost five times lower than building a typical 100-megawatt data center with the same compute capacity.Starting in 2027, SPAN plans to scale up to 80,000 XFRA nodes across the United States and provide more than 1 gigawatt of distributed compute. This network would not replace the centralized data centers being built by hyperscaler companies such as Google and Microsoft for the intensive training of AI models, but would instead be more suitable for supportingcloud gaming, contentstreaming, and AI inference, in which trained models are applied to real-world tasks.A SPANwhitepaperdangled the possibilities of retrofitting existing homes and installing larger node configurations for commercial customers. But the initial push would involve installing such nodes in newly constructed homes, with all the necessary equipment paid for and operated by SPAN.The homeowner experienceSo what does this mean for people who sign up to live in homes with attached data center nodes? SPAN would take on responsibility for paying the electricity and Internet bills for each household while offering residents either a flat utility fee—the company floated the example of a $150 fee—or possibly no fee at all, according toRealtor.com. The company is also still working out the specifics of household Internet service plans.Residents can generally expect to use household electrical appliances without interruptions, according to the company. SPAN’s main strategy is to tap into excess power capacity in each home, with 200 amps of electrical servicecapacityrepresenting thestandardfor most modern US homes built in the last 30 years.“Virtually all homes with 200-amp utility services have 80 amps available at all times, so we set that as the maximum power consumption for a single XFRA node,” Lander said. He described how the XFRA nodes would “operate as always-on loads within verified residential capacity,” meaning they would run around the clock under normal circumstances.A video animation distributed by SPAN suggests that an individual XFRA node would hold 16Nvidia RTX Pro 6000Blackwell Server Edition GPUs along with 4AMD EPYC ServerCPUs, backed by 3 terabytes of memory.The node installations alongside each house would be paired with a wall-mounted SPAN smart panel and a 16 kilowatt-hour battery—overseen by SPAN’s proprietary PowerUp software—to help manage overall energy consumption. Rooftop solar panels may also be available in certain areas.If “rare residential peaks” in electricity usage occur, the system is designed to first use the home battery backup to keep the node running as usual, according to SPAN’s white paper. In extreme cases, the system would temporarily reduce “non-critical flexible loads” like electric vehicle charging. However, homeowners would supposedly be able to use the PowerUp software to set priorities for what electrical loads can be curtailed and in what order—and Lander emphasized that such events would be “rare and brief.”Only events such as power outages, utility demand response events or safety-triggered shutdowns would lead to node interruptions. In those cases, the system would quickly
