WATERWORLD!!!
It's not a terrible idea actually, cheap to setup, low operational cost... Compared to massive solar powered data centers in the middle of a desert, Water-based data centers actually make financial sense. Of course you know this is the start of the "gMIL" Google's own private military to protect these floating fortresses.
To everyone saying satellite communication is the only practical method of data transfer... How do you think satellites communicate in the first place... same way WiMAX works... its all MICROWAVES different ranges for different distances, I doubt Google would have any problem setting up a point to point microwave system to communicate directly with the mainland (you don't have to worry about mountains on the ocean). That would cut down on latency quite a bit...
