Re: [Biofuel] Donation Info
Gustl, Just in case you (or anyone reading this) ever find yourself needing to avoid usurious local exchange rates, I have used https://www.xe.com/fx/ to trade Canadian and US currency online, and I have saved 4-5% over bank rates. I just recently bought CAD for .81 USD, and my bank would have charged me .85 USD -- they charged me less than 1 cent USD over the market rate. YMMV, my experience only. -Tyler Message: 17 Date: Fri, 17 Dec 2004 06:59:37 -0500 From: Gustl Steiner-Zehender [EMAIL PROTECTED] Subject: [Biofuel] Donation Info To: Biofuel [EMAIL PROTECTED] Message-ID: [EMAIL PROTECTED] Content-Type: text/plain; charset=ISO-8859-1 Hallo Friends, Martin lives in the state is my assumption.

[Biofuel] Biodiesel Available in Northern Va
at 7:30 a.m. to 6:00 p.m. and Sundays 9:30 a.m. to 6:00 p.m. We are located on the Pentagon Reservation at 801 South Joyce Street, Arlington, Virginia. After more than two years and lots of hard work by many of you, it is now official - effective 15 December, 2004 the Biodiesel facility at Quarters K opened for business. The Navy Exchange is very proud to offer this new member of our alternative fuels family of products at Quarters K. Along with E-85 and Compressed Natural Gas, Biodiesel is another way to Fuel the Future. The facility was constructed using a state-of-the-art above ground storage tank supplied by Clayton Enterprises, LLC Bryant Tank Systems out of Bakersfield, CA. The dispensing system is a Tokheim H322 dispenser tied to the existing point of sale system and capable of doing pay at the pump services. The construction was brought to us in cooperation with the Navy's ROICC Office at Naval District Washington. The construction was performed by McGrath Contractors, LLC and it took 40 days, start to finish. The product is B20 biodiesel supplied by Tri-Gas Oil Company, Inc. out of Federalsburg, MD. B20 is a blend of Biodiesel B100 and petroleum diesel (petrodiesel). B100 or neat biodiesel is manufactured from vegetable oils, recycled cooking grease or animal fats, and petroleum diesel. The B20 offered at Quarters K is a blend of 20% soy oil from soy beans and 80% petrodiesel. The Navy Exchange uses the American Society for Testing and Materials (ASTM) standard ASTM D 6751 for biodiesel and ASTM D 975 for petrodiesel when purchasing B20. Biodiesel is a cleaner-burning fuel for diesel engines. It greatly reduces the amount of carbon monoxide diesel engines produce. The ozone forming potential of the hydrocarbon emissions of biodiesel is nearly 50% less than that of petroleum fuel and biodiesel contains essentially no sulfur, therefore reducing sulfur dioxide exhaust from diesel engines. Biodiesel provides significantly higher lubricity as compared to conventional diesel and B20 specifically has demonstrated similar fuel consumption, horsepower, and torque as petroleum diesel. While the price of biodiesel is higher than conventional diesel, the price gap continues to narrow. The Navy Exchange price today is $2.389 per gallon. Quarters K is the first gas station in the Navy Exchange System to offer three alternative fuels, and the first location to offer Biodiesel. This project supports the Executive Order 13149, Greening the Government Through Federal Fleet and Transportation Efficiency - another way for the government to exercise leadership in petroleum reduction. The project is the dream of many with participation from both government and industry partners. The cost to develop the project was $114K. We want to thank the following departments and organizations for their insight, persistence and financial contributions to see this worthwhile project through: Department of the Army United States Department of Agriculture Commonwealth of Virginia Iowa Soybean Promotion Board Nebraska Soybean Board Maryland Soybean Board Department of Energy Department of the Interior National Biodiesel Board We look forward to seeing all of you there.

What would you *have* to run if the electricity was out? A few lights, the gas/oil furnace, a radio, a freezer? Take this into consideration if sizing a generator. Most households wouldn't need more than 5kW to run whatever is required. My parents' house in northern New York ran the essentials from a 2.5kW generator without much trouble. We get blizzards and ice storms up here, and have power outages every few years. In 1994 some areas didn't have electricity for over two weeks during the winter.

Re: [Biofuel] test batches and the JtF quality test
not really trying to say that keith has made a mistake on his site. instead I was asking for more information on how to conduct the test in a reproducible manner. I have a lot of respect for keith and what he does. you seem to lack that and I would be interested to understand why. I think that it is probably a good test to weed out the grossly under reacted batches and the way too much catalyst batches. I couldn't figure out why I kept following the instructions to the letter and getting batches that failed the quality test. 'it is cold here' seems to be the answer. maybe also 'I have soft water' is the answer. also your generalized quest against all things JtF gives you very little veracity as I have found that JtF is an invaluable resource. you and the other one that contacted me off list and tried to direct me at some other site seem to both be on another planet than the rest of the community and the rest of the community seems to be happily functioning and making high quality fuel that works well. I wasted a lot of time listening to your advice, when see new people on the list I want to warn them not to listen. I am scientific and skeptical, unless someone can give me good reasons and solid instructions their advice is usually out the door (often to my own detriment, but at least I really learn things when I do). John tillyfromparadise wrote: Hello John, It takes a brave man to tell Keith he has a mistake on JTF You are correct. The water shake test has many problems and at best only picks up Grossly under-reacted batches. Passing the shake test is certainly NOT an indication that the fuel is *well within the standard specifications* as claimed on JTF, It is only an indication that the fuel is probably not grossly under-reacted. You are also correct that what is in the water makes a difference. Hard water seperates MUCH quicker than soft water. It is also important to allow the biodiesel to sit at least over night before doing the test. There is NO simple home made test for checking whether your biodiesel meets ASTM or not. I suspect very few people actually achieve ASTM standard biodiesel The best home test is a Viscosity test. These have limitations too as the viscosity of biodiesel varies slightly depending on what the original oil was. But it is a darn site better than the Shake-em up test on JTF. But then Keith has officially declaired that viscosity is not an indicator of quality so that is never going to be discussed. I wonder what the penality for telling Keith he has a mistake on his web site is?

Re: [Biofuel] test batches and the JtF quality test
the 70*F batch was mostly separated within about 5-10 minutes but didn't really reach completion until the end of 25 minutes. thirty seconds to a minute??? http://journeytoforever.org/biodiesel_vehicle.html#quality says Then let it settle. The biodiesel should separate from the water in half an hour or less, with amber biodiesel on top and milky water below. at 140 it separated right quick. I understand how volume could have such a big effect, bubbles of the fuel seemed to form and get stuck on one another's surface tension while the separation was happening. only problem is that 150mL is just about all of my test batch so I won't be able to perform the test multiple times and vary the parameters. what I was trying to suggest here is that there are some factors that drastically affect the results that aren't even mentioned such that they can be controlled. John Appal Energy wrote: John, It is reproducable if you use larger volumes than the 8 ml total volume that you're using. A couple of fluid ounces would be more appropriate.

If the reaction went to completion, you should be able to take a 50/50 sample of water and fuel, shake radically/vertically ten times, and get a clean separation within 30 seconds to one minute, using the first water that comes out of a cold tap (ambient temp).

Re: [Biofuel] test batches and the JtF quality test
If you're looking for reproducability, you need to follow baseline, not modify a test/experiment so as to suit your own preference or conditions. You've apparently neglected to consider increases in sampling error that occur when conducting tests at micro-levels/volumes. You compound any flaw in your final evaluations by conducting not only the wash but the esterification with miniscule volumes. Unless your preparations are made with electronic scales to the thousandth of a gram, your alcohol and feedstock volumes determined by weight using the same scale, rather than relying upon glassware that forewarns of + or - 5% error factor, not to mention the + or - 10% human error factor (whether you know what end of the miniscus to take your measurements from or not) you only compound the degree of errors that are or can be represented by your conclusions. There is an enormous world of difference between reproducablity/results achieved on 150 ml samples and samples no bigger than single liters, even when conducted by professionals with decades of experience. As to your questioning the time frame that I mentioned for separation of well processed fuel, you need to take notice of the difference between the agitation period stated in my post and the general guideline you opted to modify. You also need to take notice that the wash test is not represented as anything more than a quick and simple manner of determing how an operator may care or feel reasonably safe to proceed with what he or she may believe to be biodiesel. The guidelines that are offered on this list and at Journey to Forever are intended to assist the general public in getting their fuel near or to the level that would pass the scrutiny of spec fuel, despite the fact that they may be working on dimestore budgets. If you can afford the luxury and it's absolute guarantees of finished product quality that you seek, I would suggest that you establish a procedural regimen, produce what you have reason to believe is a well-crafted product and then submit the sample to the testing methods established in D-6751.

Re: [Biofuel] test batches and the JtF quality test
Understood. I will produce a batch large enough to make several runs at the 150mL test and post the results. I consumed the remains of my last test batch in a 125mL run (it was all that was left) and I followed your agitation (10 times up and down violently). it had seperated in to two clearly stratified sections within abbout 1 minute with 60*F water however it still had lots of tiny bubbles in both parts (sort of a milky yellow and a milky white). is that what you mean by clear seperation? I still think that temperature has a drastic effect on seperation time which I will test and post the results and methods of my experiment. I would like to state to the list in general and especially kieth that no one should take any of this personally. I am posting my results so that people can point out errors. I am pointing out a sticking point that people may have (if I am having this problem other people are probably having it too). any good science is a process of peer review. one posts methods and results others duplicate ones experiments and if they prove reporducable and consistant then they are seen by the community to be valid. one of the problems that I have with all of this is that the instructions are really general and I fear that there are factors that are important but are not mentioned such that they can be controlled.

The biodiesel should separate from the water in half an hour or less, with amber biodiesel on top and milky water below. at 140 it separated right quick. I understand how volume could have such a big effect, bubbles of the fuel seemed to form and get stuck on one another's surface tension while the separation was happening. only problem is that 150mL is just about all of my test batch so I won't be able to perform the test multiple times and vary the parameters. what I was trying to suggest here is that there are some factors that drastically affect the results that aren't even mentioned such that they can be controlled.
