As Silicon Valley grapples with a burgeoning energy crisis and fierce community pushback over massive, warehouse-sized data centers, a California startup believes the solution to the artificial intelligence (AI) revolution lies in your backyard.
Span, a smart-home technology firm, is pivoting away from the traditional centralized model of computing infrastructure. In a strategic partnership with AI chip giant NVIDIA Corp., the company is launching “distributed data centers,” miniature server units designed to be installed outside single-family homes.
The units, dubbed “XFRA nodes,” are roughly the size of a standard air conditioning condenser and are designed to blend seamlessly into residential exteriors.
The logic behind the move is simple: existing electrical grids are tapped out, but individual neighborhoods have a surplus of “ghost” capacity. Span estimates that the average American home only utilizes about 40% of its available electrical capacity. By networking thousands of small units together, Span aims to create a virtual data center that provides the same computing power as a massive facility without the heavy industrial footprint.
The efficiency gains are impressive. Span told CNBC that it can deploy 8,000 XFRA units six times faster and at one-fifth the cost of building a traditional 100-megawatt data center.
“The ability to leverage existing locations that have access to power makes a lot of sense,” said Marc Spieler, NVIDIA’s senior managing director of global energy. He noted that the decentralized approach could bring AI solutions to market faster while improving housing affordability.
For homeowners, the incentive is financial. In exchange for hosting a node, Span plans to cover the homeowner’s entire electricity and internet bill, charging instead a significantly lower flat monthly fee — potentially around $150, or in some cases, nothing at all. To address noise concerns, which are a primary grievance for residents living near industrial data centers, the units use NVIDIA’s liquid-cooled, fan-less technology to ensure silent operation.
The concept is currently moving from theory to reality. PulteGroup, one of the nation’s largest homebuilders, has begun testing the technology in new developments. A 100-home “proof of concept” is slated to launch within the year, focusing initially on new construction before expanding to retrofitting existing houses and small commercial properties.
If successful, the model could solve two of the tech industry’s biggest headaches: the insatiable demand for AI processing power and the “Not In My Backyard” (NIMBY) resistance to large-scale infrastructure. By turning the American suburb into a decentralized supercomputer, Span and NVIDIA aren’t just building technology—they are rewriting the blueprint for the modern home.
