10. The M/S Sergey Oil Tanker

Year: 2009

As the last announcement made at Google's Data Center Efficiency Summit in 2009, Senior VP of Operations, Urs Hoelzle, informed attendees that the company had purchased an oil tanker: the M/S Sergey. Obviously a pun on Google co-founder Sergey Brin, this ship was to serve as a data center building that featured an oil-based cooling system. Get it? Google was launching an OIL-BASED cooling system at its EFFICIENCY SUMMIT! HAHA! Nevermind.
