The main environmental concern about ocean-based data centers involves the seawater used for cooling. Discharging warm or hot water can potentially affect oxygen levels, pH and marine life in the surrounding waters.
That heat is already apparent at the few seaborne data centers now operating. HiCloud, the engineering contractor for China’s Hainan underwater data center, has reported a temperature increase of less than 1 degree Celsius (1.8 degrees Fahrenheit) in the seawater near the facility. SIN01 in Sines, Portugal, also returns seawater about 1 C warmer.
Many marine species depend on stable water temperatures for breeding, feeding and migration, raising concerns that heat released by multiple underwater data centers could create localized thermal pollution and alter marine ecosystems. And the ocean is already under pressure. UNESCO, the United Nations agency for international cooperation, including in conservation, estimates that about 60% of marine ecosystems are already degraded or used unsustainably.
The idea has been around for quite a while now
And sure enough, the maintenance costs proved too much for it to have caught on, conveniently making the whole thing obscure enough to pull out for another round of hype.
speaking of hype cycles I heard on the radio news this morning that some researchers have figured out how to send odors digitally, so prepare for another round of “smell-o-vision” “news”
Who needs the oceans anyway. It’s just empty space with no life in them at all.
I swear. These wanks are trying to kill us all.
They might want to put themselves in the ocean first, but great idea: sea water is famously friendly to machinery and accessing things on the sea is very easy and cheap at all times of the year.
