The Fjord-Cooled Data Center

1sockchuck writes "A new data center project in Norway plans to use a fjord-powered cooling system, drawing cold water from an adjacent fjord to cool data halls. The fjord provides a ready supply of water at 8 degrees C (46 degrees F), eliminating the need for an energy-hungry chiller. The Green Mountain Data Center joins a small but growing number of data centers are slashing their cooling costs by using the environment as their chiller, tapping nearby lakes, wells and even the Baltic Sea."

From what I've been able to tell by talking to these 'greenies', any environmental impact is bad. It's not enough to be carbon neutral, or conserve energy, save the whales, or whatever else is currently in vogue in their movement. It is a political movement that is based on a sliding scale of "purity". I can easily see one of them extolling the virtues of living in a house that has no electricity, is built entirely out of clay, and they don't cook their food (because fire releases carbon). What's worse, they feel guilty about having any modern conveniences, and so they try to buy indulgences like "carbon credits" or "EVA cars" ... which when you look into the total lifecycle of the vehicle and it's total environmental impact, you don't wind up any better off than a conventional car. A lot of environmentalism is just a shell game... it's moving the responsibility around so they can claim they're "carbon neutral" or whatever while someone else (usually the government, or some corporation) are the bad guys.

    The bottom line is, the problem with the movement is that they can't see that progress towards environmental goals are only achievable by being economically competitive. I mean, everybody right now is going crazy about living "grid free". But the problem isn't the grid. The 'grid' is just a collection of wires and transformers. It's the management and production of that resource that is the problem; If the environmentalists wanted to "save the planet", they'd come up with a way to transport electricity over very long distances with minimal losses. That, right there, is the kind of tech we need to reduce our dependence on coal, oil, etc. Until we can cheaply move energy to where it's needed on demand, we're stuck with dino fuel because it's the only thing with a high energy density that can be built right now -- you can't build a nuclear power plant anywhere in this country right now even if you wanted to... and even if you could, nobody wants it near a city, which is where it needs to be to be useful.

    Avoiding the problem of hot water in the Fjord can be done even with GW heat sources by using a combination of holding dams and distributed outlet pipes - that's the sort of thing that's done with nuclear power plants on rivers. The "passive heat exchangers" would be cooling towers,

    With those dams and outlet pipes, is there a heat transfer to the surrounding environment, particularly air? Yes - you have your heat exchange.
    Is there a high energy mechanism (fan, pump, etc) set up to increase the transfer rate? No - you have passive.

    That's a form of passive heat exchange.

    The people in charge of designing and running the plants are not the problem. I've known a lot of people in that field. Very smart, very thoughtful.

    The problem is the politicians who make the decisions don't have a fucking clue. They then decide to cut budgets, put things in bad locations, etc. The people designing, building and running them don't have the options or resources available to alleviate the issues. They can write reports and make suggestions, but the politicians and bureaucrats tend to ignore these.

    Put a plant away from any place that's got an active fault line, and at least 20km from an ocean (with some adjustment for altitude), and you shouldn't have a problem. A modern plant least has triple redundancy and safety features that quash the reaction is they lose power (or are told to do so).

    I wonder if someone would calculate how much power/heat would be needed to raise the temperature enough to affect it.

    Considering that this "Fjord" Is actually the east side of a small island which has the North Sea on the west side - a huge amount!

    This is a really good and valid concern, we have a small spring fed pond that is ~20 acres that has native brook trout, they thrive in this cool water (this species no more than 55F for happy fish, water ~48F fresh out of the ground in the middle of the summer). I did the math on what it would take in energy to kill them because we wanted to run a circulator and exchanger for low cost air conditioning. There really isn't anyway we could actually kill them given the thermal mass of the water and how fast it is refreshed from the ground. But if you keep going with the math, something like a datacenter could easily kill all the fish, or at the very least greatly hinder there lively-hood.

    Economically competitive is just a cop out. What it really means, is that you have a limited commitment towards change. In my personal view, which has had heated debates, we are fucked already. Leave economics out of it and make the hard decisions now. That does mean start building as many nuclear reactors as possible right now because they are the most immediate solution to massive amounts of power generation that can be used immediately for heating, cooling, industry, etc.

    I suspect you misunderstand economics. Throw out any ideas of economics being about $'s, the $ is only used in economics as a unit of measurement, and even then only a proxy. Economics is concerned with "the distribution of scarce resources", leading to the principle objectives being improving efficiency (of allocation) and/or increasing the availability of resources (i.e. reducing scarcity). There is no stated time constraint, the implication is you should consider the entire period that it is possible to do any kind of planning for.

    When people try to argue against environmentalism using "economics", they generally either misrepresent the problem as being entirely the unrelated moral issues, or constrain economics into a short timeframe and selfish perspective. This is to totally ignore the problem. Aside from moral considerations, the entire human aspect of the environmental problem is an economic one.

    Pure economic argument is almost entirely on the side of rational environmentalism (emphasis on rational, since "environmentalism" is a generalisation almost to the point of absurdity; there is no common standard of where the balance lies between pro and anti, there is no common standard of values).

    If you consume 100 units of scarce resource now at the cost of 100u of same later it is a net nil on the "scarcity" objective, all you've done is decided the allocation. So what is the net position for allocation objective then? This is where it gets more interesting. If the future is going to be more plentiful then it is reasonable to assume the better allocation is to consume those resources now, but if the future is going to be bleak then we should save those resources. Everyone knows a tin of beans is more valuable to a starving man than the same tin is to a well-fed one. I dare say men of science agree that the future is looking relatively bleak.

    Pretty much the entire situation can be thought of using that principle. Oil obviously fits easily into the above illustration, but it's fundamentally the same when we're talking about cooling data-centres now at a cost of fish in future. Cheap energy now at a cost of clean air and other pollution effects. "Resources" is meant very generally, encompassing all bringers-of-utility whether it be oil, fish, clean air or much less tangible things.

    Now, there's two big caveats. Well, not caveats, but important factors that are bloody difficult to incorporate into the planning. Firstly, technological innovation. This can lead to both increased absolute availability of resources and improved allocation. For example, cheap, efficient solar panels may result in a greater power availability, particularly for dispersed settlements where plants are ill-suited, while freeing up oil for other uses. However innovation generally requires resource consumption now, not just consumption in the course of research but also for the economic conditions to spur research investment. While the Bush administration argued it to a ridiculous extreme, it's still totally valid to put some weight on the importance of the present over the future. The difficulty is how much weight to place on so much uncertainty?

    Secondly, economic competitiveness. This is actually a valid factor for consideration, not just for selfish reasons but because it impacts both the allocation and scarcity of available resources. It's not so much economic competitiveness per se, but how it ties into economic efficiency. An economy that is not economically efficient is n
