Ehh, it could sound that way (green washing). I remember an article from 1 or 2 years ago where Microsoft did a "pilot" test of this and the general consensus is that in a datacenter

• while you fix part a you break part b of the identical server next to it.
• Moore's law means that every 5 years or so you spend more on electricity and storage than you would for the smaller more efficient hardware
• having 0 human interaction and 0 added dust and 0 oxygen and the ocean at 40 decrees farenheight meant that no additional cooling required. (Maybe some cpu airflow to the external 40° air)

Time (and investments) will tell if this is the solution to costly land based air heat pumps to cool datacenters with human interactions.
