Mark Zuckerberg has given a sneak peek into the advanced technology Facebook employs.

In a series of photos posted on Facebook, Zuckerberg shared information about some of the new technologies Facebook has been building, starting with a look at one of its data centres in Europe.

The shared photos are from Facebook's facility in Luleå, Sweden. He writes, "It's a key part of our global infrastructure, and it uses a variety of local natural resources to increase efficiency and save power."

Zuckerberg goes on to explain,“The temperature in the area is below 50 degrees most days, so we use large fans to pull in the outside air to naturally cool the thousands of warm servers that line the centre’s broad hallways. A dozen hydro-electric plants operate on nearby rivers, providing a reliable and renewable power source. The whole system is 10% more efficient and uses almost 40% less power than traditional data centers.”

Zuckerberg's post showcases one of the ways Facebook deals with the persistent problem of data-centre cooling. Data centers consume vast amounts of energy, and much of that is given off as waste heat.

Facebook isn't the first to use a natural environment to keep its processors cool. Microsoft has been testing an underwater data centre that uses seawater as a coolant.
