Google confirmed on Friday that it had sold one of its mysterious barges that was idle and floating at the Port of Stockton's Rough and Ready Island in Stockton, Calif.

During the last quarter of 2013, Google sparked different rumors when it started building barges in between San Francisco and Oakland. In November, the tech giant confirmed that the floating barges will serve as interactive learning centers, but others believed that it will be used as showrooms for Google Glass. It was then moved to Stockton in March this year, after failing to secure permits from the U.S. Coast Guard and the San Francisco Bay Conservation and Development Commission.

But even before the alleged traveling showrooms were officially launched, the Portland Press Herald reported that one of the four barges was sold. Terminal owner, Roger Hale, said that the barge was bought by an unnamed international barging company and will be transferred to an undisclosed location. The containers, however, will go straight to the scrap yard.

Google released a statement on Friday regarding the sales.

"We can confirm that the barge has been sold," Google said.

Google did not reveal the cause of abandoning the project and its other plans for the rest of the barges, but it undoubtedly cost the company a fortune, as it usually costs $4 million to construct a new barge.

On the other hand, the Stockton officials were also waiting for updates from Google.

"It just sits there like it did on the day it arrived," said Stockton Port Executive Director Richard Aschieris to Mercury News. The officials didn't see any signs of work on the floating barge since its transfer.

Plans for Google Glass remained unclear after the company started doing random sales of the Google Glass. According to The Verge, Google might have thought that floating showrooms are costly, and it would be more economical if they put up retail stores for new products instead.
