‘Dumping’ is considered anti-competitive behaviour in a lot of places. This sounds a lot like that.

There are a number of 6-8GWe nuclear plants that dump 15+GW into the nearby sea (or in the case of Bruce, into Lake Huron). I don’t see it being much of an issue. Better than virtually any other cooling option.

The issues are maintenance, energy source, and equipment supply.

RAM’s main advantage over HDDs/SSDs is fast access times.

Needing to fetch anything over the internet would make it faster to just use HDDs.
