i am really liking the homebrew biodiesel processors for sale over at biodiesel warehouse. for the price of a new laptop ($2,000) you can get a complete biodiesel processing system that generates 55 gallons of biodiesel fuel in just 3 hours of hands-on processing time. if you’re not liking the hands-on approach, they offer a fully automated biodiesel processor model costing $7,000 but there’s no measuring or mixing of materials required (processes 50 gallons of fuel in about 60 hours). so nice to see these alternative fuel systems becoming much more accessible to the general public.
