Salmon Biodiesel at Oceans Festival June 7th Anchorage

Come down to the Anchorage Parkstrip Saturday Afternoon for the Alaska Oceans Festival and visit the Alaska Biodiesel and SVO Network booth. We'll be sharing space with our non-profit sponsor, the Alaska Chapter Sierra Club.

Salmon oil biodiesel demonstrations will be offered every hour or so throughout the afternoon, but be sure to stick around for the evening beers and music.

Son Volt is playing a free show 7:30pm, with Fairbanks jam-Americana band Sweating Honey opening at 6pm. The 4pm keynote speaker is Alexandra Cousteau, granddaughter of legendary explorer Jacques-Yves Cousteau.

As a side note, we're in need of clear 2-liter soda bottles (with caps) for upcoming biodiesel events. If you have a few please drop them off at the booth!

Book Review: Do It Yourself Guide to Biodiesel

Reading the "Do It Yourself Guide to Biodiesel" by Guy Purcella was like having a long conversation with someone who is very knowledgeable about biodiesel, but on a different page.

Purcella sells a plastic-cone based biodiesel processor and obviously believes in safe, quality homebrew made in his design. Thankfully the book isn't a 230 page advertisement, but it does go to lengths to describe why the plastic cone-processor is a good idea.

Personally, I am opposed to mixing heated flammable chemicals in plastic.

He also strongly encourages folks to buy a pre-made processor or at least a kit. Now, the kit and DIY resources he recommends - Utah Biodiesel Supply, the Infopop Biodiesel-SVO forums and the Collaborative Biodiesel Tutorial are the same ones I point folks too, so I'm not sure where our paths diverged.

This may be the book for you if you want to buy a processor and have it "just work." Which, interestingly is the conversation I've been having recently with a few local folks.

Purcella goes into great detail describing everything except building a processor: the standard personal story, why petroleum is bad and biodiesel is good, oil collection, storage and titration, and quality testing homebrew, as well as storing, filtering and pumping the final product.

It's got a lot of information. Perhaps a little too dense for those just interested in biodiesel, but good for folks who are thinking about buying a pre-built reactor. This is probably the only book that lists a "buyers guide" to pre-built systems, and really lays out the big picture of what's required beyond the processor.

Of course, for those hardcore DIY types, my favorite book for actually building a processor is Home Brew Biodiesel from b100supply.

I adore biodieselSMARTER

All the information you need to home-brew biodiesel is floating somewhere out there on the internet. It's finding the right information with the angle you want that's difficult.

Issue number 6 of biodieselSMARTER showed up in my mailbox yesterday and I couldn't put it down. First of all, it's written by folks with sustainability in mind. The full-page ad inside the front cover reads "The greenest car you own? Mass transit. Try not to drive at all. Icebergs will float in your honor... Respect the Biodiesel." Nice.

In addition to the regular columns, this edition includes glycerin composting trials and horror stories of illegal glycerin dumping. There are articles on desert thriving moringa and snow-planted camelina as feedstock crops. Also in the mix are a couple of farm-scale case studies, a bicycle-powered reactor built by high school students, and a piece on PrairieFire Biofuels, which serves both the SVO and biodiesel scene in Madison, Wisconsin.

The camelina article is especially pertinent for us Alaskans. In fact, Hans Geier - the Delta Canola biodiesel farmer - sent me a small packet of camelina for a little test plot I've got going in the orchard. Much to my chagrin, Hans and some other local farmers have been really keen on blending unheated oils with diesel and/or other thinners. Interestingly, these Albertan farmers are doing exactly that, with locally grown and crushed off-spec canola. Although in general I'm not a proponent of blending, I'm glad to see biodieselSMARTER embracing the larger sustainable biodiesel-vegoil community.

Don't have a subscription yet? It's a little 'zine, but filled with quality information, and it's only TEN BUCKS for a year-long subscription.

37 degrees and light.

Yep, May 1st marks the start of the outdoor biodiesel brewing season. It's also the day we're supposed to take the studs off the tires, but since there was a big snowstorm the last few days of April the state is letting us keep them on until May 15th.

There's little bit of snow on the shady side of the house, and a few of the big dumb mosquitoes flying around. Thankfully their tiny, fast and numerous cousins haven't hatched yet.

It's only 37 degrees out, but I pulled the clear frying oil cubies out of their cardboard boxes and let them sit in the sun all day. They flowed smoothly out of the boxes and through the paint strainer into my 55 gallon drum. Although the little harbor freight clear water pump was a little slow moving the oil from the drum to the appleseed. This year's new addition is a refrigerator compressor that pulls some suction to prime the pump. That priming feature is a very, very nice addition.

I've got the first 2008 batch drying in an open top drum with a bubbler in it, but I don't know how much drying it will do in the wet, heavy, almost-freezing air.

I'm also just about out of the few hundred gallons of SVO (Straight Vegetable Oil) that I filtered for 2-tank SVO driving all winter. It's time to get busy!

Oh yeah, today I sent my $1.72 in taxes to the state for my April SVO use. I'll have to have a talk with my representative about personal-use exemptions. He lives a couple miles down the road, and Alaska is very familiar with subsistence and personal use issues.

All this and I'm working by the twilight at 11:00 pm.

Yep, May in Alaska.

Earth Day biodiesel and SVO on AK radio.

AK radio ran a nice 5 minute segment on Alaskans burning vegoil and biodiesel during their Earth Day program. You can download the entire 04/19/2008 program from the archives at akradio.org.

Here's the summary for the show:

April 22nd is Earth Day, and on this week's AK, we'll pay tribute to the planet. We'll learn about sustainable agriculture, and visit a hotel that runs on the same stuff you use to cook your French fries. Plus, recycling old Crocs, and figuring out which plastic bottles are safe, and which ones might land you in hot water. It's all on AK from the Alaska Public Radio Network.

If you're looking for just the biodiesel segment, a low-quality (32k mp3) version is available here.

Book Review: Home Brew Biodiesel - a fabulous DIY manual.

B100supply has put out Home Brew Biodiesel, a unique and extremely helpful guide to brewing your own biodiesel. It reads a lot like a lab manual or a build-it-yourself guide: lots of pictures, lots of detail, lists of tools and supplies needed to build and operate a water-heater based biodiesel setup.

The Appleseed processor plans, wash tank plans, misting set-ups, overflow systems, basic electric control panels and more fill the first half of the guide. The second half provides step-by-step instructions to operating your new processor, and the appendices cover quality testing procedures, a few intermediate-level processing methods and waste stream management techniques.

Much of this information is free on the internet, but B100supply has done a wonderful job of wading through the crap to bring you the gems.

Most DIY biodiesel books spend a whole lot of time telling personal stories and explaining why petroleum is bad and how biodiesel is going to save the world and our pocketbook. Home Brew Biodiesel skips all the fluff and tells you how to build a processor, make your fuel, and test it for quality.

It's remarkable that the book not only covers collecting and testing oil, but goes into such processing details as how long to heat, how long to mix, and how to test if your batch is done. With the wide range of opinions on the internet, it's nice to have an authoritative guide to start you on your way.

This book does not go into acid-base reactions or methanol recovery, but even advanced brewers will find some of the testing techniques, waste stream treatments and wiring setups interesting.

Unfortunately for Alaskans, B100supply usually ships by UPS, which makes even little parts quite expensive. But they do offer their Home Brew Biodiesel book through cafepress, where the shipping is a reasonable five bucks.

It's definitely the best guide I've read for actually building a processor.

Biofuels [kind of] Blamed in Food Crisis

The Anchorage Daily News ran a New York Times article at the top of the Nation and World section today that the ADN retitled "Biofuels blamed in food crisis."

Other than the inflammatory title, the article itself is pretty good. It admits that biofuels - especially corn-based ethanol - does have an impact, but that it is "relatively small and that energy costs and soaring demand for meat in developing countries have had a bigger impact."

The article goes on to report that "grocery prices in the United States increased about 5 percent over the last year."

A decade ago we were lamenting that family farms were failing because of low crop prices. The soybean growers had a market for their meal, but the oil was terribly undervalued. They went ahead and formed the National Biodiesel Board to create a market for their soybean oil. It looks like they succeeded.

That being said, it's easy to take a good idea and implement it poorly. The giant Three Gorges Dam in China is a terrible example of hydropower. Altamont Pass in California was built in the middle of a raptor migration route, giving a wind power a bird-killing reputation that has been hard for it to shed.

There's no way we can grow ourselves out of our fossil fuel addiction. Biofuels, however, can be a sustainable part of our future energy mix.

Capturing waste fryer oil and oil from discarded fish carcasses could provide over 13 million gallons of biodiesel in Alaska every year. Combine this with the Canola production potential of the old barley farms in Delta, and we will have a significant impact on our local energy needs - sustainably - and without completing with global food supplies.

P.S. If you want more insight on the food vs. fuel arguments check out Clayton's post over at gas2.org.

Dr. Diesel and Peanut Oil - Myth or Legend?

Ah yes, Rudolph Diesel's 1893 compression-ignition "diesel" engine was invented to run on peanut oil, so it's okay to burn old fryer grease in our diesels, right?

I've seen this peanut oil story published in books and spread widely across the internet. Unfortunately, the real history isn't as clear as all that.

Gerhard Knothe, one of the USDA's top biodiesel researchers, found passages in "Chemical Abstracts" 6:1984(1912) and 7:1605(1913) in which Dr. Diesel writes:

at the Paris exhibition in 1900 there was shown by the Otto Company a small diesel engine, which, at the request of the French government, ran on Arachide (earth-nut or pea-nut) oil, and worked so smoothly that only very few people were aware of it. The engine was constructed for using mineral oil and was then worked on vegetable oil without any alterations being made.

So yes, a early unmodified diesel engine did run on peanut oil, but it wasn't Dr. Diesel's first engine.
