'Something big and mysterious is rising from a floating barge at the end of Treasure Island, a former Navy base in the middle of San Francisco Bay. And Google's fingerprints are all over it,' Terdiman writes. 'Whether the structure is in fact a floating data center is hard to say for sure, of course, since Google's not talking. But Google, understandably, has a history of putting data centers in places with cheap cooling, as well as undertaking odd and unexpected projects like trying to bring Internet access to developing nations via balloons and blimps.'"
