Want to make vegetable oil

I have a homestead in Alaska, and would like to run a small tractor and generator on biodiesel. Because of the VERY high cost of transporting fuel (must be flown in by charter plane), I want to make my fuel completely at the homestead.

I have found great sources for how to make the vegetable oil into biodiesel, but none on how to make vegetable oil (small, home, production). I think soy beans are a high producer of the oil, but how is it extracted? Is there a better crop. It needs to grow well during rainy, cool, summers.

I think it would be very cool to make my own fuel from scratch. I suspect it would be cheaper too. (Diesel costs 3.35 per gallon + 2.50 per gallon shipping)

 

I think Stephen Gaskins Farm in Tennessee is doing that and actually has courses they give.... Maybe look into that?

 

I believe you need yourself a cold-press. Unless you have more resources at your disposal.

didnt really read this site, but could be a good place to start.

Now you should be able to run the generator on straight oil, making biodiesel is only nessesary for running the motor cold, once the temp rises, then the oil will combust on its own. Either a warm motor with cold oil, or a cold motor with warm oil should run just fine.
Last time I made biodiesel was a good 10 years ago, I think the methanol at the time was our only expense, ended up costing us about 45 cents a gallon to make biodiesel. Of course prices were cheaper then.
