Is Google's ocean powered data center finally setting sail?

Recently, there has been a great deal of speculation into two mysterious structures built on barges located off the east and west coasts of the United States. Allegedly, these structures belong to Google but the company has declined to comment on any details.  One theory is that these structures will be used as a floating retail stores for Google products, however most believe these barges will be hosting data centers at sea – a concept which Google patented in 2009. 


In 2009, Google was granted a “water-based data center” patent which would utilize seawater as its primary power source and cooling method. Tide-powered generators would capture energy via wave motion while sea-powered pumps and “seawater-to-freshwater heat exchangers” would be used for cooling.


According to Google, their water-based data center would be capable of producing plenty of wave energy at a distance of 3 to 7 miles offshore and in 50 to 70 meters of water. The wave energy machines, which are approximately 11 feet in diameter and approximately 492 feet long, can connect end-to-end to form a farm of machines. Each machine is able to generate approximately 750 kilowatts of power and approximately 40 machines spread over a square kilometer could produce around 30 megawatts of power.  


What are the advantages of building on the water?


In their patent application, Google states the following:

"A military presence may be needed in an area, a natural disaster may bring a need for computing or telecommunication presence in an area until the natural infrastructure can be repaired or rebuilt, and certain events may draw thousands of people who may put a load on the local computing infrastructure. Often, such transient events occur near water, such as a river or an ocean. However, it can be expensive to build and locate data centers, and it is not always easy to find access to necessary (and inexpensive) electrical power, high-bandwidth data connections, and cooling water for such data centers." (Click here to view the United States Patent for Google's Water-based Data Center)


Another advantage is the energy savings incurred by powering the servers with wave energy and cooling the servers with sea water rather than traditional air conditioners.


What’s the catch?


While there are numerous advantages to Google’s water-based data center, they may not necessarily outweigh the risks. Storms and other natural disasters are inevitable and it’s common knowledge that water and electricity don’t mix. What happens if major electrical components of the data center become damaged in the same natural disasters they are supposed to be assisting with? What about the threat of pirates? A Google data center would be the ultimate treasure chest.


For now, the purpose behind these structures & barges remains a mystery.  As we wait to see whether or not this floating data center theory holds any water, tell us your opinion.


Is wave energy a truly cost-effective renewable energy resource?  Would a water-based data center be a smart economical & environmental move for Google or other companies with similar ideas?

Very interesting post - I enjoyed reading it for a number of reasons.  One, I have family who works at Google and even she has no idea what is going on with those barges!  Two, I really want to know what those barges are! :) And three, I enjoyed the perspective that they might be useful in the event of a natural disaster.  Considering that Google is located in an earthquake zone it only makes sense that they would be coming up with contingency plans incase of disaster.  Having one close to home (SF bay) and across the country (incase of a unthinkable disaster with the headquarters and SF bay is compromised, probably makes sense.  The addition of this back up plan also utilizing wave energy is SO GOOGLE!  It makes me think even more that it is a Google project.  I like there outside the box thiinking.  While I don't know much about wave energy so really can not comment on if it is cost effective or not, I think if it is able to be used, it is simply a secondary benefit to Google's (or whoever's) contingency planning.  I do like the fact though that they are not thinking narrowly and thinking outside the box and trying to incorporate as many things as possible into this project.  As for a water based solution being good for Google or other companies, I say, why not.  In the end someone has to be the first to dip their toe in the water.  Maybe the first few trys might not be successful but eventually they will be.  Someone has to be the trailblazer.


I enjoyed the post - would be interested to hear if you, or anyone has any comments to my post.
