Microsoft declares its underwater data center test was a success

Underwater pods can reduce latency by moving cloud services closer to customers.

Note that 100,000J/y is a very very small amount of energy, ~3.171 milliwatts. I don't know how much power these pods use, but I'm willing to bet it's at least a million times highter (thousands of watts)

I think I may also have messed up on my conversion of KM^3 to liters. I think it should have been ~5.6^e24.

So, 56,000,000,000,000,000,000,000,000 liters.

Let's call it 100,000 of these again. That's 56,000,000,000,000,000,000 joules you'd need, per container. Let's call it 100 billion joules per container per year. That's 56,000,000 years it would take to raise it one degree. Another way of expressing it is if you wanted to raise the ocean 1/10th of a degree, over the course of 100 years, it would take 5,600,000,000,000,000,000,000 joules per year to do so. If each unit puts out 100,000,000,000 joules per year, you would need 5,600,000,000 of these things. If each one is 10 meters squared space, you'd need 56,000,000 km^2 of space. Or approximately an area 10 times the size of Europe.

This is all if my calculations are correct. Which, again, they almost certainly are not.
In fact, my guess is that by the time I've finished editing this, they've already been proven wrong.

Edited words to make units more clear
Edited again to try fancy maths regarding number of units needed

A cubic kilometer is 1000^3 = 1 billion cubic meters. A cubic meter of water is one metric ton, 1000kg, 1000 liters.

A cubic kilometer of water is thus 1 trillion liters. That's less than one billionth of the ocean. It really is unfathomable.

I'm an engineer so I cannot do math. That's why there's Wolfram Alpha: https://www.wolframalpha.com/input/?i=volume+of+water+in+the+oceans+in+liters

If you want to be more accurate about the difference between seawater and plain water, you can also ask about that:
https://www.wolframalpha.com/input/...1+degree+celsius+difference+in+kilowatt+hours

And get an answer of 1.5 * 10^18 kWh of energy to move the temperature of the ocean by one degree.

https://www.wolframalpha.com/input/?i=worldwide+power+production gives worldwide power production as 2.2*10^13 kWh per year.

That brings us to https://www.wolframalpha.com/input/...erence+/+worldwide+power+production)+in+years for 70,000 years worth all of human electricity production to heat the oceans by 1 degree. Global warming, as we've been learning, is much faster at it than the world's largest aquarium heater could ever hope to be.
