Spud: A potato powered Web server
The instructions for making one are here, if you want to make/build one yourself. Of course, you will still need to figure out how to stop the potatoes from rotting.
Every once in a while we hit something so geeky that it blows our heads, this time Spud blew our potatoes. Because, Spud is the name for the world's lowest power consuming web server that runs on raw potato power. That's right Spud uses potatoes for power, about 5-6 of them and serving around 0.2 hits/sec, which means it will not survive any kind of digg effect unless it uses toothpicks ;)
