Last November, in our "Top 20 Econudrums," we asked whether it was more environmentally friendly to read the paper in print or online. It's a question with a surprising answer: As it turns out, it's often greener to read dead trees. This is true largely because of the giant environmental impact of servers. But thanks to some techies in Zurich, that could change soon.
Here's a little background: Server farms—also known as data centers—are the enormous housing facilities that make the internet possible. A single Google data center, in Oregon consumes as much energy as a city of 200,000. That's because servers not only have to be on 24/7, they need to be kept cool 24/7. Up to 50 percent of the power they use is just to keep them from melting down. Overall, the internet is responsible for 2% of global carbon emissions, about the same as the aviation industry. And as the internet becomes increasingly prevalent in China and India, well, that means a whole lot more Xiaonei pages and Orkut accounts that will need hosting.
So it is good news, nay, great news, that the IBM lab in Zurich has developed a new cooling technology by attaching teeny-weeny water pipes to the surface of each computer chip in a server. Water is piped within microns of the chip to cool it down, then the waste water is piped out hot enough to make a cup of Ramen, heat a building, or keep a swimming pool warm. The new cooling system will reduce the carbon footprint of servers by 85 percent and the energy use by 40 percent. If this technology were in MoJo's office we could ditch the electric tea kettle and just go to the server closet to steep our chai. Check out a video of the technology after the break.
