Google Building Something on a Barge in San Francisco Bay

Maybe a floating data center, or a Google Glass store

The mystery surrounding a large structure built on a barge docked in San Francisco bay is deepening. Is it a floating Google data center? A floating Google Glass store? Or something else altogether?

On Friday, I reported exclusively that a company, very likely Google, has set up shop on Treasure Island, located between San Francisco and Oakland, and has been building a large structure made from shipping, or cargo, containers on a barge. Some evidence suggests it might be a floating data center, including the fact that Google itself has a patent for such a concept.
