Heat Your Home By Hosting the Internet

As the internet continues its growth it consumes more and more electricity because larger server and data centres are required. Microsoft has come up with a brilliant idea to allow ‘the backbone’ of the internet to continue to grow while helping heat houses and providing a faster internet.

Microsoft has released a research paper that suggests that small data centers be put in people’s home and heat those homes using excess heat from the servers.

The research paper comes at a time where internet properties like Facebook, Google, and Microsoft are building huge data centers housing thousands of servers that simply pump their hot exhaust into the frigid air of Oregon, or other chilly states. There have been a few prototype data centers that use their waste heat to warm the houses in local towns, but Microsoft’s Data Furnaces take this idea to the next step: instead of building mega data centers that are efficient in terms of scale, Data Furnaces are micro data centers that are housed in the basements of regular homes and offices. These Data Furnaces, which would consist of 40 to 400 CPUs (between 1 and 10 racks), would be ducted directly into the building’s heating system, providing free heat and hot water.

The genius of this idea is that Data Furnaces would be provided by companies that already maintain big cloud presences. In exchange for providing power to the rack, home and office owners will get free heat and hot water — and as an added bonus, these cloud service providers would get a fleet of mini urban data centers that can provide ultra-low-latency services to nearby web surfers. Of course the electricity cost would be substantial — especially in residential areas — but even so, the research paper estimates that, all things considered, between $280 and $324 can be saved per year, out of the $400 it costs to keep a server powered and connected in a standard data center. From the inverse point of view, heating accounts for 6% of the total US energy consumption — and by piggybacking on just half of that energy, the IT industry could double in size without increasing its power footprint.

The main problem with Data Furnaces, of course, is physical security. Data centers are generally secure installations with very restricted access — which is fair enough, when you consider the volume and sensitivity of the data stored by companies like Facebook and Google. The Microsoft Research paper points out that sensor networks can warn administrators if physical security is breached, and whole-scale encryption of the data on the servers would ameliorate many other issues. The other issue is server management — home owners won’t want bearded techies knocking on their door every time a server needs a reboot — but for the most part, almost everything can now be managed remotely.
