Data Furnaces: Crazy Idea or Practical Solution?

Will the cloud live in your house, and heat your home? That's the unusual concept put forth by researchers from Microsoft and the University of Virginia in a paper published earlier this year,who suggested that large cloud infrastructures could be distributed across offices and homes, which would use exhaust heat from cabinets of servers to supplement (or even replace) their on-site heating systems. The research, which got an initial burst of publicity back in July, has now been picked up by The New York Times.

The ability to recycle server heat - using air from the hot aisle to warm nearby office space - is a proven concept being used in a growing number of data centers, usually to warm offices in the data center or adjacent buildings. The Times story acknowledges several of the obvious drawbacks - security of the servers and temperature control in the "server room" - but also examines the economics of the arrangement. The Times writes:

"According to the researchers’ calculations, a conventional data center must invest about $400 a year to run each server, or about $16,000 for a cabinet filled with 40 of them. (This includes the costs of building a bricks-and-mortar center and of cooling the machines.) Having homes host the machines could reduce the need for a company to build new data centers. And the company’s cost to operate the same cabinet in a home would be less than $3,600 a year — and leave a smaller carbon footprint, too. The company’s data center could thus cover the homeowner’s electricity costs for the servers and still come out way ahead financially."

The paper describes three types of Data Furnaces:
