Quick post today. The Kyoto Wheel has been around since 2007, so it is fair to assess this technology in cooling data centers as a 'mature' concept. Those of you who are already using it know the answer already: Yes, amazingly this somewhat cumbersome brute is actually quite effective in using outside air to cool your data centers.

Techtarget have written a sort of review of the Kyoto Wheel, giving an overview of the workings of this slow-moving, hulking monstrosity. It has some great strengths (low energy consumption, efficiency) as well as mighty drawbacks (space, not very usable in the warmer parts of the year). But the general conclusion remains that the Kyoto Wheel is a very viable and mature solution for data center cooling.
