The beauty of the phrase is that it’s universal.
Is it? I want to talk with aliens as much as the next guy, but so far it seems like the vast majority of the universe is a vacuum--biologically speaking.

> is it significant or is it insignificant Then a study (ideally multiple studies) should be commissioned to find this out. We shouldn't just do it because we can, and because armchair physicists are pretty sure that it's insignificant. Because, that's what Microsoft (and their partner) did. They did it because they could. Remember when we, as a global society, believed that CFCs would have an insignificant impact on…
I doubt these would add more heat than a single new volcano does, but I’m all ears. According to research[1] tectonic activity adds about 3 cubic km of magma/lava each year to the oceans (that’s 100 times the annual production by mauna loa.) [1] http://volcano.oregonstate.edu/book/export/html/138
In which case, we'll just end up talking past each other, so I'll wish you a good day.
It seems an additional hurdle is anti-fouling. Those barnacles and algae act as an insulator, making the cold-water cooling advantage less and less of an advantage.
If the surface were that hot, would sea creatures still want to live on it? I have no idea what their range of tolerance is, but I'd assume that they're well adapted for living on relatively cool rocks. And if it's not that hot, then it seems like there's not a cooling problem. (To be clear, I'm speculating without any real knowledge of this subject, and welcome the inevitable corrections.)
Microsoft patented the way to power these data centers using tidal energy in ocean itself. They patented in 2017. http://www.whatafuture.com/microsoft-underwater-data-centers...

The ocean is host to a very wide number of creatures and bacteria, some live in arctic cold waters, others on volcanic vents, and every range in between. There's a good saying for this, roughly translated, that nature doesn't love an empty spot — if one type of plant or bacteria won't live in an area, someone else will quickly settle in.
We have "nature abhors a vacuum" in English
I was left wondering whether they were referring to the project, or just Azure Availability in general. /s

This sounds a whole lot like the "global warming couldn't possibly be our fault (because: volcanoes) so let's not change anything" line of thinking, just applied to oceans instead of the atmosphere. In which case, we'll just end up talking past each other, so I'll wish you a good day.

I'm sorry but this is such a 'goalpost' movement here that simply takes away a lot of context. The whole point of doing a dc underground is to reduce the hvac energy consumption which has a much larger ecological impact in terms of heat generated, power usage, potential greenhouse gas usage. The name of the game here is energy efficiency and conservation. Use less power by reducing power distribution loss at scale. W…
I don't think jacquesm is off the mark in asking these questions, especially: > what is the direct ecological impact of doing this at scale What is the impact on sea creatures if we put these giant heated cylinders in their territory? Is there any impact? I really doubt we have the answers yet. > at scale ...also implies that there will be more than one. So if one heat cylinder doesn't do anything, what about 10? 100…
Asking the questions here on HN instead of in a place where the designers are likely to read them makes it seem it's more of a karma grab than a reasonable "I have concerns" type situation that he really wants to do something about. Nor are random HN commenters very likely to have big, fact-backed contributions btw. It's just alarmism under the pretense of innocently asking questions.

> the only way it leaves the planet is by black body radiation But, if you're heating the oceans, you're putting an entire other mass (the atmosphere) between yourself and space. So you're heating the water, the water is heating the atmosphere, and the atmosphere is radiating that into space. It's adding a step to the overall cooling process.
That's not really how it works. The land and ocean radiate their energy directly into space. This works through emitting mostly infrared frequency light for which, just like visible light, the atmosphere is mostly transparent.
