Ethanol powered still

[DarkSotM]

I'm new here so feel free to put me in my place.

I was wondering about using alcohol to power a still. I have use the heads cut off various thing to power my camping stove (Simple pop can alcohol stove) and it got me wondering if I could power a still off of all the undrinkable head cuts. While I'm sure it can be done, I guess the real question is it worth the effort, and how might someone go about this?
