Oil-Cooling 802.11 Infrastructure
gomoX writes "A group of 802.11b fans in Tordera, Spain, are running a wireless node on the roof of a building, with the idea of a free wireless network for everyone on the neighbourhood. Its a system running linux with a home made can antenna, mounted on a plastic tool box in the roof. To keep it cool under the sun and protect it from rain, wind, they have immersed it into vegetable oil (yes, the whole thing). As oil is non-conductive, everything should run fine. The site is in Spanish, here is the google translation and the google cache."
In Australia our major power supplier here does that for all of their high-tension cables that go underground - they're encased in a layer of plastic, but the rest is oil. It not only is cheaper and lighter than other sheathing forms, but it insulates and dissapates heat at the same time
