I still check this out occasionally, missed the notification this time. I'm not very close to Duluth, much closer to Iowa. I know of permie groups in the twin cities and there has been a get together around labor day at harmony park north of Albert Lea for several years now. I'll mention to that they hosted the north american permaculture convergence in 2014 in case you missed it.

Biofuels like vegetable oil, biodiesel, or ethanol are generally not economical except where an individual happens to have ready access to the required resources. For diesel fuel this means inexpensive vegetable oil, and for ethanol this means inexpensive fermentable sugars. In general, the process is not cost effective unless one can get these resources at virtually no cost... and this is rare. It's all really fascinating, but rarely practical. Wood seems to be (to me) the most practical biofuel. It will heat a home, heat water, and can even be used to fuel internal combustion engines via gasification. If one desires to live off grid and achieve energy independence, then a combination of photovoltaics and wood gasification is the best system I've considered. A gasifier can be used with wood fuel to provide space heating and water heating, and it can power a generator for battery charging during inclement weather when the solar system is unable to generate sufficient electricity. In some settings (such as a cold climate) it can be practical to use a wood gasifier exclusively for heat and power generation. It's also possible to use wood to power automobiles.
This video might interest you: https://www.youtube.com/watch?v=jz2v4f2UNL0 . This individual was using vegetable oil to power his engine while collecting the heat from the engine. It's a very efficient system when most of the energy is put to use. Interestingly, Mr. Boak experienced difficulty in acquiring vegetable oil shortly after this video was taken. He then modified his system to be fueled by wood chips using a gasifier. Here is a link to his web site where this conversion is discussed: http://www.powercubes.com/listers.html .
This video features Mr. Wayne Keith who has done amazing things with wood gasification for automotive use: https://www.youtube.com/watch?v=JlNACAEa3vo

But they didn't say how they did it, I mean how do you just make an engine that runs off that? I actually thought it was illegal because why isn't everyone doing it then? lol
The folks I know locally who use reclaimed veg oil get it from a guy who collects it, processes it and resells it. It's my understanding that you have to modify a diesel engine vehicle (the folks I know both drive old Mercedes). You can make it yourself but you have to have the right setup.
The Dervaes family (Path to Freedom) in Pasadena makes their own biofuel - you can see a list of related blog posts here: http://urbanhomestead.org/journal/category/homebrew-biodiesel/
I find it fascinating what alternatives people come up with!

It truly does all depend on location and application. Use what is in abundance locally, especially if it's a "waste product".

The answer is simple. Buy a south facing plot with a spring fed river running through it with sufficient fall to make a hydro scheme economic.

There are lots of permie folks all over the country and the world who need help with their projects. You could sign up, drive the RV to a farm, spend time learning and sharing and get to travel at the same time.
Check out some of the posts here...

In fact I think my spot in Wyoming is the best !
I have known many folks who wouldn't even think of setting foot in Wyoming. I would never live in a place that gets too hot.( I get heat exhaustion very easily.) Even if it was the garden of eden.
So for me it is up to the individual and what they are looking for.
It seems like the beauty of permaculture is that it can be applied to every setting on earth.
So what is it that you are looking for in a place to live?
