Protein Skimmer?

[nano10]

I was talking to a guy at work about my need for a Protein Skimmer and he said to build this one, he uses it and said it works great for him. Unforunitly I didn’t ask him enough questions and now he's on vacation for two weeks. Does anyone know how the Protein Skimmer works? Does it require a powerhead? Does it go into a sump or outside of it?
