Nvidia and Span is turning homes into small AI data centers, using spare household electrical capacity to run compute nodes while giving hosts cheaper power and internet.

The idea starts with a mismatch: many homes are wired for 200 amps, but they often use far less than that, so Span wants its smart panel to measure unused capacity and feed an XFRA Node without overloading the house.

Each node is serious hardware, with 16 Nvidia RTX Pro 6000 Blackwell GPUs, 4 AMD EPYC CPUs, and 3TB RAM, which means this is not a hobby server but a rented slice of AI infrastructure.

The battery matters because AI workloads hate interruptions, so it buffers demand spikes, supports demand-response events, and shifts work away if a home loses power.

The business claim is that distributed nodes can avoid the slowest part of data center growth: getting land, permits, utility approval, grid upgrades, and power access.

Span plans a 100-node proof of concept in Q3-26, then aims for more than 1GW of annual capacity from 2027.
