The cheesy joke to serious post ratio of this thread is about 1:1, LOL.

you can end up with heating up a small portion of the sea near the coastline, affecting it immensely.

this one is actually from a power plant discharge, but you get the idea.


so to be specific, those hot waters have less oxygen levels where most intolerant species will die from.
and algae blooms will occur more often originating from those hot plumes of water, further killing more marine life.

Interesting, but surely they have planned for this, being as big as they are, Microsoft would have had to hire people to look into these kind of things.
Maybe there will be some way of ensuring that the warmer water is being circulated into larger volumes of water, ie, the out going piping for the heated water leading well out into the ocean rather than outputting in the same area as the datacenter.

Thread Starter 
About the heating, here is a quote from the article:
Quote:
One aspect of the project that has the most obvious potential is the harvest of electricity from the movement of seawater. This could mean that no new energy is added to the ocean and, as a result, there is no overall heating, the researchers asserted. In their early experiment the Microsoft engineers said they had measured an “extremely” small amount of local heating of the capsule.

“We measured no heating of the marine environment beyond a few inches from the vessel,” Dr. Lee said.

So, no heating problem.

Another interesting stuff from the article is the "refactoring". Considering the change of environment, they could rethink the way the data centers were made from scratch. It's something in the lines of instead of making a humanoid robot to clean your house like you do yourself, you can just build a R2-D2.

uhhh, they're transforming tidal forces directly into heat, the total energy is unchanged, but the local heating will be present.
if this is a large scale farm, it would have a noticeable impact.

Microsoft technician: uhm, hard drive failure on a server. Server located at... HELP ME GOD!


Future Datacenter technicians job requirements:
- Certified in advanced networking;
- Certified with previous experience in hardware troubleshooting;
- Scuba diving.

they won't actually need to scuba-dive, they'll have to pull up the entire capsule up.
they can't open the capsule underwater and risk seawater getting in.


i'd like to bring up a point, why haven't they thought up of using the municipal water supply as cooling, and directly contribute to district heating?
all that wasted heat can be used to heat up my shower water, i would even gladly pay up some incentives so long as it's cheaper than my gas/electric costs.

thermal pollution is actually very damaging to nature.
copper-nickle alloys lasts quite a long time in sea water.
copper alloys are also resistant to biofauling.
and lastly, copper is a much better heatsink than most other metals.
Diving has tough me that sea water will eventually screw everything, be it a wreck or your own equipment. Just saying.

that gives us 20,000L + 5ºC = 117kWH
20,000L = 20cubic meter

How did you determine the volume of water? 20 cubes is not a lot of water.
The submerged unit will probably displace more than 20 cubes of water

That is an interesting idea, I was even thinking if you had to tap directly from a main line and dump the return back into it. A line moving a few mega liters a day of water may not see much of a temp increase if you only heating a few cubit meters of water. I doubt this would scale well though

Don't you reckon they'd just have a lift going down into the structure from above sea level?

What...? Microsoft doing something good? Or trying to even.
