This was just posted by Keith on the "Australian Preppers" FB page www.projectworldawareness.com/2010/09/life-on-this-earth-just-changed-the-north-atlantic-current-is-gone/As I said there, I aren't qualified to comment on the science, but I did see a show a year or two back where they stated that the Gulf stream is all that keeps the UK and parts of Europe habitable. If that's correct and the stream has gone they (and to a lesser degree us) are in deep shit. I'd better add an extension for my UK family and friends  Anybody know if it's for real? No, I don't know much about this stuff. I've read that one of the fundamental concepts of the earths climate is that the Southern Hemisphere is warmer than the Northern Hemisphere however.... and that when this ocean conveyor stuff was being theorised circa 100 hundred and fifty years ago correct conclusions were being drawn from incorrect rationale... I will try and find the link I got this from. I posted it to the guardian website about a week ago so it should be on my profile if I dig around a bit! I don't really understand the 'THERMOHALINE' concept but that could be a good keyword to plug into google to get you started. (um, yeh- got it all backwards btw ;>) |

Isn't water a good conductor of heat compared to the atmosphere? That could be true.. out of pure interest Background[edit]
Before the development of modern thermodynamics, it was thought that heat was an invisible fluid, known as the caloric. Bodies were capable of holding a certain amount of this fluid, hence the term heat capacity, named and first investigated by Scottish chemist Joseph Black in the 1750s.[2] Today, the notion of the caloric has been replaced by the notion of a system's internal energy. That is, heat is no longer considered a fluid; rather, heat is a transfer of disordered energy. Nevertheless, at least in English, the term "heat capacity" survives. In some other languages, the term thermal capacity is preferred, and it is also sometimes used in English.
i found on wiki: 'heat capacity' !??!Personally I am led to believe that 'heat' is the last form of energy- i.e. everything ends up as heat! |

Daniel, you ate correct. That's why water coolers in computers are always leaps and bounds ahead of a fan/heatsink coolers in performance. there's a big computing project going on in western australia that is using a certain aquifer to water cool its bits... ... someone said that there might be a problem but how would anyone confirm it? |

Going back when I first looked at liquid cooling for computers (early p4) The concept was great for over clocking your CPU, but the system worked super well with a lot of power (from memory, you needed a 750w+ power supply) the largest concern was plumbing, the man group of early public use was nerds with $10k plus computers playing computer games... At the time the setup was a little expensive, they done a computer tower around liquid cooling (roughly 1/4 the size of modern computer that was great) Never herd a real issue outside the thought of using liquids to cool valuable electronics is a disaster waiting to happen |

The only real issue is if you bust a leak XD I saw a guy use a line to and from his pool for his water cooler system! Plus side is it was silent, no fans needed as it didn't have a radiator. Lol

Yep, can't remember the difference but it's significant. That's why it's important to not get wet in the great outdoors if it's cold.
