Just don't plan on being able to move your desk.

Copper would be a waste of money tho. Use one of the many types of plastic hose already made for this application.

Yes, because plastic is a muuch better conductor for heat than say, copper.

since those aren't degrees.

Without proper thermal throttling, your roof could come off, even with a passive heatsink.

I think Antec makes a two-story-high fan that might work perfectly in such a situation, but the neighbors might be bothered by the LEDs.

If it was really an issue... plug up the holes and don't tell anyone? They're 6 meters long, not 6 meters wide; it shouldn't be too difficult.

Oh you definitely want to tell the new owner what it is. Though, the thought of someone finding the tubes and digging up the foundation to find out where they're connected to the water main only to find out they are just a giant loop is kinda funny.

That first link is so bizarre, sitting within a post which otherwise seems very logical. My brain is short circuiting as it tries to find the connection between underground piping and spinach pizza.

I got a bunch of raised eyebrows when I had two four-gang electrical outlets (one from either leg of the house power) and an exhaust vent fan installed in one of my closets when we built our house. I wanted it for a server farm but couldn't convince anyone that I wasn't going to be farming something else.

I assume you meant to use a period. Commas haven't ended sentences since; well. ever?

Or sell the house to Ted Stevens and tell him that's where his Internet comes out of.

We did the same thing with WiFi.

Depends on what it gets filled with.

damn SE always ruining an Architects fun .... :)

I dunno; I've been in two houses where the floor slab has been ripped open and partially re-poured.

My parent's house, when we put a basement bathroom in, needed the slab ripped out around the drain lines for the new drain connections.

My current house has new slab in the front 1/3d of the basement, where the furnace and hot water tank are. I don't know what was wrong with the old concrete, but in the rest of the basement, you've got to be careful with the broom or you sweep up concrete instead of just dust and dirt.

It's only the slab, not the foundation (footings and wall). Breaking the footings open, that's bad. Undermining the footings, that's bad.

Floor slab? This way to the drains....

Besides, if the pipes fail, cut the ends flush with the slab, plug with mortar, and get on with your life. That's what they did with the old natural gas supply pipe; it's cut and plugged on both the inside and outside, where it used to go to the city main.

Come to think of it, they did the same thing with the oil tank fill and breather pipes at my parents when we had the oil furnace removed. (Very important to plug the filler side, especially if the oil company doesn't get the cancel notice to the delivery truck....)

There. Fixed that for you.

P.S. No, I don't think I'm clever.*

* I preemptively agree that I'm not clever.

exchanging the heat through plastic into a concrete biomass should work just fine.

For the typical house built on top of a concrete mass, exchanging heat with it may work fine.

But if your house is built on on top of a concrete biomass, RUN! IT'S ALIVE!! RUN!!!

While we all appreciate the thoughtful and incisive commentary on the appropriate symbol for "feet", I must humbly point out you misspelled "apostrophe", which has the unfortunate effect of putting your credibility as a master of punctuation in some... doubt.

But yes, since Slashcode fails to recognize ANY of the HTML4 entities for "prime" , we will have no choice but to fall back on that ancient artifact of the bygone typewriter era: the apostrophe key. I blame GP commentor's lamentable faux pas in choosing the wrong key on a lack of training in typewriter keyboarding. This modern computer keyboarding is an anarchic madhouse of unregulated freedom and undisciplined overabundance of choices. It's good to have the leadership and mentorship of those who know better, in order to provide guidance to youngling slashdotters. Thank you, evilbessie.

And you'll need to make sure you cover the entire ground-foundation interface with a paperthin layer of Artic Silver. Remember, the tip of a credit card works well for this, though it might take you a little longer than on a processor...

I'm maybe moving to a house that has a cellar with a well in it, an active one that water flows through, so the cellar is damp and maybe slightly cooler than normal.
Would the cellar not automatically act as a sort of cheap ground source heat pump, in terms of equalisizing the temperature of the rooms above it?

You're an idiot.

Seriously.

Don't post here anymore.

Whoa damn, Brigadier (12956), you just got served!

Air-source systems have the advantage of constantly circulating air moving the dumped heat away from the building.

Then you just need to find a way to get the ground you're dumping heat into to move about and do the same. The solution is quite simple, really: build your data center around, or on top of, a volcano! The constantly circulating lava in the underground magma chambers will dump all the heat you can put out far away from your now smoldering data center.

Let me guess: This guy worked on NASA's Mars orbiter.
