We recently discussed using fish oil for biodiesel, and the pdf file on UniSea's project in Alaska was mentioned then: http://www.aidea.org/Unisea.pdf Discussion here: http://archive.nnytech.net/index.php?view=29516&list=BIOFUEL "The assessment of any impacts on the engines' operability and maintainability will not be completed until after test operations conclude in October 2002. Results to date have been very encouraging, however, with no apparent adverse effects on the engines." More than a year ago, and nothing since. Fish oil has a high iodine value - sardine oil: 185, that's higher than linseed or tung oil. That means it's a drying oil, it polymerises: "the oil irreversibly polymerises into a plastic-like solid". Biodiesel made from fish oil will also polymerise. See: Iodine Values -- High Iodine Values http://journeytoforever.org/biodiesel_yield.html#iodine So maybe they use it quickly, before it dries. I didn't find anything in that UniSea file about iodine values, drying, or polymerization. I think, Steve, if you're going to encourage people to make biodiesel from fish oil, it needs a warning that it might polymerize. There's also been previous list discussion of UniSea and their project, lots of info here, with discussion on fish fat etc.: http://archive.nnytech.net/index.php?view=12829&list=biofuel&related=1 Biodiesel from algae is not a ready-to-use technology, certainly not for backyarders, it needs more work for that. List members have investigated it, run up against problems for practical application, and abandoned the idea; some have tried it but never reported any results. That's not to say it's not worth further investigation, of course it is, but it's not yet a viable technique people can use.
