[Q]: (CNN) -- Google has finally broken its silence on the mysterious structure atop a barge floating in the San Francisco Bay. "Google Barge ... A floating data center? A wild party boat? A barge housing the last remaining dinosaur? Sadly, none of the above," the company said in a statement e-mailed Wednesday to CNN and other news outlets. "Although it's still early days and things may change, we're exploring using the barge as an interactive space where people can learn about new technology," the statement continued. The barge, docked at a pier on Treasure Island, houses a four-story structure made from shipping containers. Speculation about its purpose has been swirling since discovery of the vessel -- and of three similar barges across the country -- first made headlines early last week.Google: Mysterious barge in San Francisco Bay will house an 'interactive space'Statement: Barge structure will be "where people can learn about new technology"CNN affiliate KPIX has reported structure will be high-end showrooms for Glass eyewearThree similar barges, including one in Maine, have been spotted
