Hitachi's Water-cooled Laptop

surfacearea writes "The Register has an article about the new Flora 270W Silent Model, a Japan-only 1.8GHz water cooled laptop. Apparently the pump and piping is all held behind the LCD in the lid. I wonder how much extra weight that consumes." But best of all, it means now laptops have a chance to spring a leak!

Re:Water?

Pure (distilled) water is actually a very poor conductor. It's all the impurities in solution that make most "water" into a conductor.

Close, but not quite. The rate that heat is generated isn't a function of the cooling system; it's a function of the heat-disappating components (and, true, only a high-power processor would have a water-cooling system).

Given an insulated enclosure and non-stopable heat generation, the second best you can do is to evenly distribute the heat among all components (actually, the best you can do is distribute more heat to components that can take the heat - i.e. heat the aluminium just to the point of melting at the same time silicon reaches its melting temperature). A water cooling system would better distribute the heat (as opposed to when I did this- my poor little fan was running, but there was no air in my bag to move).
