plus they can even go super-deep bore holes and extract heat from down below, geothermal power anyone?
the only issue is costs, its far more cheaper to sink a water-proof vessel, than to dig deep underground.
It's not going to raise the water temperature. Maybe it they cover the entire sea flow in server rooms... maybe? No polar bears will die because of this.
About putting it underground doesn't sound entirely good either. First, it's quite warm under the surface of the Earth. I think around 12 -16C. Don't know if that's a constant around the globe. I just know that from a mine I visited recently (135m below the surface). Depends on the depth we go too. At a certain point, the further we go down, the warmer it will get. Second, it's a constant temperature with a lot of earth. There is also a lot of thermal mass. If you don't have proper ventilation for the heat generated by the servers, it's just going to bake down there. So if we put them underground, beyond the cost of mining the facilities, you would still need proper ventilation.
If they can use that heat for well... heating up on the surface, that would be good too. Again, you would have to develop a system to transfer that heat.
Putting them on the sea bed (if it's cost effective) sounds like a great idea. Just make cradles that can hold them down there safely. There are a lot of materials that are corrosive resistant so that won't be a problem. I think the problem is logistics. Now you have to run deep sea cables to connect to these drivers. Also, there are probably a lot of regulations from Countries / Municipalities saying how far out in the sea you have to place these. I'm sure they can't just be on the coast. Another thing to consider, as is mentioned in the article is maintenance. It would probably be a pain in the butt to go down and retrieve the drivers or do inspections. However, they claim it can last five years before an inspection is required.
I think it's a really great idea and a step in the right direction but there is a lot to work out.Edited by Slaughtahouse - 2/1/16 at 4:47pm
