Google has been granted its patent for a data center that floats on the ocean. Though the patent mostly describes how such a thing would work, it also addresses the use of wave and tidal power, as well as water cooling to even land-based data centers that are nearby.

The majority of the patent deals with the logistics of ship-based data centers, though it also examines the use of wave power, tidal power, and seawater for providing electricity and cooling to land-based data centers that are close enough to water.

Of course, there’s nothing to stop Google from deploying a floating data center powered by conventional fuel sources, but such a vessel would be more limited by range or fuel capacity. Not only would it have to carry enough fuel to power itself, it would also have to make sure to power the systems it carries. Using a water-based generator would not only be more practical and efficient, it’s also a significantly greener solution.

Despite the patent, however, Google may not be the first company to send its data centers out to sea. A Silicon Valley startup called International Data Security (IDS) announced in January of 2008 its intent to set up a fleet of data-serving cargo ships. These ships would not only come with standard storage services, but also with amenities such as private offices, overnight accommodations, and galley services. The first ship was scheduled to set sail (or rather, hang out in San Francisco’s Pier 50) in April of 2008, but according to a blog post by IDS partner Silverback Migration Solutions, that plan got pushed to third quarter 2008 and we were unable to find any further information on the project.

The Silverback blog alos outlines a few interetsing points.  The value proposition for ship based datacenters is very similar to that of land based datacenters, with a few noteable exceptions:

–Current market demand for data center space continues to outpace
supply, and using ships as data centers can reduce time to market by as
much as 65%.

–Cap-Ex costs to bring a ship into data center operation is
approximately 2/3 that of a land-based facility.

 Even pirates need a business plan. J. Peter Pham, an analyst of African affairs at the James Madison University, looks at the economics of guns, captains, and $2 million dropped into the sea in waterproof containers. Plus, Per Gullestrup, CEO of Danish shipping company Clipper Group, has dealt with pirates first-hand — he says they’re tough negotiators.  When he ironed out the ransom details with the pirates, he had 3 demands:

1. The pirates showed “proof of life” (that the crew was still alive)
2. That they could drop the money from the air (faster than getting it there in a tug)
3. That the pirates fill up the ship with fuel.
