On: Want an energy efficient datacenter? Build it underwater

And how does data get into this data center? Where is the power comming from? All those connections still must go through penetrations. It can be done, i just question the worth.

Power from a seabed cable or nearby offshore power. Data by the same cable. Sealing a cable or a small container is not hard to do at all.

Penetrations are not necessary. It is possible to use electromagnetic radiation to transfer both data and power.

EM isn't going to travel very well or very far through water. You would want something exposed on the surface, and preferably in very close proximity. Every time you transform power, you're going to incur losses.
