I don't know about this idea - I think it's weird, but it might work - still, it's weird - The ocean as watercooler: floating data centers stay cool in ars technica:

"…A new Silicon Valley startup called International Data Security (IDS) has sent some big waves through the data storage industry by announcing (PDF) its intent to set up a fleet of data-serving cargo ships. These floating data centers will come equipped not only with standard storage services like SAN (Storage Area Network) and NAS (Network Attached Storage), but also with amenities such as private offices, overnight accommodations, and galley services."

"…To save money, IDS is purchasing decommissioned ships that were scheduled to go to the scrapyard, then refurbishing them in drydock. According to founder Ken Choi, the first ship—which will also house the new IDS headquarters—is scheduled to come online in April, and it will be parked at San Francisco's Pier 50 along with its sister ships. Each ship has approximately 200,000 square feet of usable space. The company plans to deploy as many as 22 ships in North America and 50 ships worldwide.
