I’ve found the discussion of alcohol power and stills very interesting. Building a still has been something on my list of things to do, but I never seem to get around to making it happen. Here’s a link to [a PDF of] the [still building] plans I’d like to follow. 
The plans are concise, relatively simple and, best of all, free. I think the web site says you can build one of these for about $65, less if you have access to an inexpensive stainless steel milk can.- Tim R.
