The public face of AI is something we are all too familiar with. Turn on your phone, tablet, or computer — hey presto — all the power of AI at your fingertips. However, the technology that powers all that AI requires a large network of data centers and network infrastructure.
The use and power of AI are both increasing exponentially, pushing the need for more data centers. However, this is not as simple as building a large shed, cramming it full of technology, and wiring it up. There are a number of constraints that prevent us from building adequate data centers. Among the factors affecting the industry are environmental impact, inefficient electrical infrastructure, and public concerns. The latter is reflected in the growing protests against AI data centers.
Now, one company believes it may have a solution that could help offset this impending shortage of computing power. San Francisco-based SPAN is not a tech giant; they are a clean energy solutions company for homes.
The company has released details of a plan that could ease the problem of computer power and the cost of your electric bill. The company plans to use the spare electrical energy available in many households to power a “small data center.”
The system, known as XFRA, may not be as small as Odinn’s portable data center, but it fits in about the size of a home air-conditioner, requiring no installation in a data center. Let’s take a closer look at XFRA, and what carrots the company is offering to entice you to install an air-sized unit in your garden.
What is Span’s XFRA program?
The XFRA SPAN system is a distributed, scalable computing cloud. To understand why such a system is being considered, we need to look at the constraints currently holding back the development of data center capacity. In particular, electricity distribution issues. In some cases, the grid cannot deliver power to new data centers, even if power is available somewhere in the network.
XFRA addresses this limitation by exploiting the fact that the residential electricity infrastructure has a lot of capacity left over. Actually, the grid is configured to operate at maximum capacity, but most of the time, it only needs half of this capacity. The XFRA program proposes to use this capacity to power its micro data centers.
Each XFRA node is a liquid-cooled “compute module” built around a bank of eight enterprise-grade GPUs. Importantly, controlling this is a smart SPAN electrical panel. This panel monitors the home’s power cycle and uses backup capacity when the home’s needs allow.
Along with the server and control panel, the whole house battery is part of the installation. Although homeowners should always consider a few things before installing a new home battery. The battery ensures that the computer hardware has a stable power supply that can withstand power outages or fluctuations.
Finally, each node is connected to the SPAN orchestration layer, which treats each distributed node as part of a single computing resource, similar to a cloud.
The company hopes to have a pilot program operational by 2026, with the next large-scale deployment in 2027.
What’s in it for homeowners?
The size of the units means that there won’t be too much interference from those installing them, at least aesthetically. However, very few people would rush to install such a system unless there were some incentives offered. From a hardware perspective, the most obvious benefit is the inclusion of a whole-home battery. While this supports the XFRA node, it also serves as a home power backup.
Although the company does not promise that the homeowners can do it completely just say goodbye to electricity bills, there are financial grants available. In particular, it provides a monthly fee for hosting XFRA space, essentially subsidizing energy and high-speed broadband bills on a large scale. In some cases, funding may be large enough to provide these services for free. There is also an optional solar panel scheme.
However, before we all rush out and install a data center on our premises, there are some potential downsides to consider. First of all, having such expensive technology in your backyard can raise questions about theft and vandalism.
There is also some uncertainty about the basic principles of the program. For grid planners, residual household capacity is not a luxury; an internally designed feature that is often used to smooth out peaks and valleys of power demand. Power issues may also occur in cases where there are clusters of XFRA nodes in close proximity. This can result in certain areas receiving more power than expected under normal conditions.
While everyone would love free electricity, the success of XFRA will depend on whether the benefits of having a small data server next to your grill are worth it.
