[biofuel] Senior Research Project
Hello, I haven't submitted much to the list lately, but I would like any input you have on this subject: I'm preparing to do my senior research project/thesis in Chemistry this next semester (Spring 2003) and I have chosen to do it on biodiesel. My plan is to try different methods to see what can improve the biodiesel cloud point by trying different alcohols (such as my chemistry professor suggested the use of 1-methoxy-2-propanol as a possibility for the alcohol since it has a higher oxygen content.) I plan to experiment with different ratios of ethanol and methanol, and maybe trying isopropanol or another branched alcohol. There are other plans such as your basic viscosity, calorimetry and instrumental analysis that I have available in the lab. I have many options of where to go on this one, and will most likely narrow my options as the experiment goes along. Any suggestions would be appreciated.

[biofuels-biz] Chemistry internships in biodiesel/ethanol production
Hi, I have been a member of the biofuels for about a year now, and biofuels-biz list for about a month, as some of you may know, and I am currently a senior studying Chemistry and I am looking for an internship opportunity for next summer. I plan to do my senior research/thesis on something related to biodiesel or ethanol and believe that an internship in that area would assist me greatly, and would also like to work in this area to see if this is really where I would like to go with my career path. If any of you know of any opportunities, I would greatly appreciate any information. Please send any email to: [EMAIL PROTECTED] and use "Chemistry Internship" as the subject line so I don't end up deleting it (I have a problem with junkmail) Thank You, JEFF Yahoo!

[biofuel] switchgrass to ethanol/other topics
How much starch or fermentable material is in switchgrass when it is fermented. I have been looking into switchgrass but they don't say how they process it to ethanol. Is there a cellulosis process for doing this? Corn for silage (whole plant) typically yields 5-7 tons of dry matter per acre in WI, and I would assume that switchgrass would yield close to the same in this colder climate. Last summer, sugarbeet farmers in MN were letting their piles of beets rot since the sugar market was so low last year. With MN being one of the top ethanol producers in the nation, why aren't they fermenting the sugarbeets for ethanol too and saving these farmers their rear ends? I'm sure it would be better than letting them rot! Secondly, the mention of using vinegar vs roundup for organic farming is very intriguing, but household vinegar actually only contains 3% acetic acid. How do you get stronger concentrations of vinegar and how hard is it to make via fermentation? JEFF Yahoo! Groups Sponsor -~--> Buy Stock for $4 and no minimums.

[biofuel] reverse osmosis of alcohol
Has anyone ever considered using reverse osmosis to remove water from alcohol? I am not talking about the distilled product which is 90% alcohol, but when it is done fermenting and contains 10-20% alcohol, would you be able to get enough water out to make it worthwhile to do so? I suppose that since water is H2O and is a very small molecule compared to ethanol CH3CH2OH, that there would be a permeable membrane selective enough to not let the alcohol pass through. JEFF Yahoo!

[biofuel] why aren't there ethanol plants in CA and NY...
I would actually make more sense to ship the ethanol to CA or NY than to build plants there since the raw ingredient: corn would then have to be shipped in instead and the shipping costs from the midwest would then result in the grain prices going down in the midwest (the economy essentially recoups the cost of transportation by making the product worth less so it is cheaper to transport - just look at the milk industry in America and you'll see what I mean.) The result of all this would also make the grain prices higher in CA and NY instead and cause even more strife for the Midwestern farmer. If you just make the ethanol and ship it from MN or IA or wherever else it is manufactured, you can ship the concentrated product to the end location - it makes sense to make cheese in WI before you ship a whole tanker truck of milk to Florida and it should also make sense to ship the final product... If the MTBE is not made in CA they have to ship that in anyway don't they? So what they heck is the problem? MTBE is actually only half as effective as Ethanol as an oxygenating agent since by molecular weight, MTBE has only about 18% oxygen and Ethanol is about 35% - that's not including density but it seems to me that you would only need 5% ethanol to get the same oxygenation as 10% MTBE JEFF thoughts?

Peculiar "Farming for Fuel" oversights was Re: [biofuel] Re: Is it now time to talk to your congressman?? again
I agree that much of the grain produced in the world is directly fed to livestock and there are advantages and disadvantages here: advantages: a)the nutrients found in meat are more available to our bodies than those found in plants (especially proteins and fats) b)dairy cows fed distillers grains will produce more milk with higher protein (the stuff is extremely expensive because of that by the way) c)animal manure is the most efficient fertilizer compared to those made from oil! (and this should be the #1 consideration for renewable fuels since not all oil becomes gasoline but a major chunk is converted into ammonia and other fertilizers which increase yield while sacrificing the microorganisms which are the "lifeblood" of organic farming. disadvantage: a)except for feeding to dairy animals for milk production, the use of grains to feed cattle for meat is a very inefficient one. my conclusion: BALANCE --- In [EMAIL PROTECTED], "Appal Energy" <[EMAIL PROTECTED]> wrote: > No Motie...no confusion here. > > Are you aware that distiller's grains are fed to livestock? > Are you also aware that the vast majority of arable landmass is > dedicated to livestock? > Are you aware that the primary product of low-oil yielding > soybeans is feed meal for livestock? > > In a nutshell, the vast majority of all agriculture is dedicated > to livestock - even in the midst of "farming for fuel" issues. > Just from the total caloric inputs vs. caloric yield equation, > you might consider taking a look at Rifkin's "Beyond Beef" or > Robbin's "Diet for a New America." > > The simple facts of the matter are that most of what you and > others call "energy crops" at present are actually primary > livestock feed sources.

[biofuel] Re: what could it be?
35% HCl (muriatic acid) is roughly 14.8 Molar (14.8 moles/Liter solute) If you aren't familiar with the concept, 14.8 Molar is extremely concentrated and is powerful enough to take the biodiesel fatty acid esters and break them back into ffas and methanol. That is why you don't want to wash with a strong acid, and that is why once you add too much acid, you can't regenerate the biodiesel by adding NaOH to neutralize the pH. In fact, if you add too much HCl, it will even react with the methanol present (alcohols can act as weak bases in the presence of a strong acid) and the methanol will become methyl chloride Basically, adding NaOH will neutralize the excess HCl and the FFAs which are weak acids but this doesn't help you any and by add The vinegar is not strong enough at 3% acidity to break any of the ester bonds but will react with the excess sodium methoxide remember acetic acid is a VFA-volatile fatty acid meaning that it is a short chain fatty acid and behaves similar to LCFAs-Long chain fatty acids like oleic and palmitic that are found in fats, except VFAs are soluble in water, and their esters are also soluble in water, so a methyl acetate formed by reaction of acetic acid and sodium methoxide will be soluble in water and can be washed out... and excess acetic acid (vinegar) will not react with the biodiesel but since it is water soluble will be washed out and not remain in the biodiesel level... I think the "guk" formed is the reaction of ffas with chloride to become acyl chlorides... I'm not sure about this but if the -OH group is replaced with a -Cl, Chlorine which has a higher affinity that Oxygen will be harder to convert into biodiesel, but the Sodium Methoxide should be strong enough to do it. (H + Cl break and the H goes to the Methoxy group to reform methanol, while the -Cl goes with the acid to create an acyl chloride). Once all the FFAs have been acylated with chlorine, the HCl turns to methanol and reacts to form water and methyl chloride which will dissolve in the nonpolar ffa layer. It would not be a buffer system, just the HCl reacting with the biodiesel which raises the pH to neutrality as it neutralizes the HCl and creates the acyl chlorides and methyl chloride which are not terribly acidic. Once all the biodiesel and methanol been reacted, the excess HCl has nothing to react with and the pH drops sharply. I've never made biodiesel, but I'm relating to my knowledge of chemistry but I may not be 100% correct.

Nitric acid would work good because it is a strong acid and as a strong acid has the capability to break the ester bonds, but that isn't the problem. Nitric acid (HNO3) when added to the mix breaks into an -OH group on the acid, and an -NO2 group on the glycerol molecule. NO2 is nitro and w/glycerol is nitroglycerin and you know how unstable it is.

[biofuel] acid catalyzed...
oils and fats are basically a combination of long chain acids plus short chain alcohols (esters). (glycerine is an alcohol) Just like when you add a base like sodium hydroxide to an acid like hydrochloric, you get a salt plus water as products. The stronger the acid/base reaction NaOH + HCl are both strong respective base/acid so their reaction goes to completion and the products are neutral. Any time you add a stronger acid/base to the original ester, you get a reaction because fatty acids become amphoteric (meaning that they can behave as an acid or base depending on the situation) If you add sodium hydroxide to a triglyceride, a reaction takes place which breaks the ester bond and creates water and an organic salt (you get free glycerol plus a salt of free fatty acids and Na+) If HCl is added, the fatty acid becomes a base since the fatty acid is much weaker than HCl so you also break the ester bond between the glycerol and free fatty acid, but you get a fatty acyl chloride (which is a -Cl replacing the -OH of the carboxyl acid group and is undesirable and which is why you don't want to use HCl as a catalyst.) If you know the properties to Sulfuric and Phosphoric acids, they bind hydrogens via H-O- bonds so when the acid is added to the oil, the free fatty acids become phosphorylated or sulfated (depending on the acid of course) and this is a phosphoester or sulfoester bond since the -OH is replaced by -OSO3(1-) or -OPO3(2-) I hope this is making sense. As long as there isn't an excess amount of acid or base catalyst added, none of the glycerol will react with the catalyst (since alcohols also have an -OH group, they too act as amphoteric meaning they can be acid or base depending on the reaction. In soap making, Sodium Hydroxide is so basic that it deprotonates the glycerol to create sodium glyceride (not glycerate which not the same as glycerol) And if a strong acid such as Hydrochloric were used, the - OH group would once again be removed in favor of the -Cl (remember that in both cases, water is also formed.) In using the catalyst method, a small amount of the acid is added to the oil which breaks a few fat molecules into glycerol and ffa's. When the sodium methoxide is added, it reacts with the weak acid formed by the phospho/sulfoester and releases the sulfate or phosphate to attack another fat molecule. Another thing... the reason why you don't want a free fatty acid without a phosphate group when reacting the methoxide is simple. A FFA has an -OH group on the end, and a phosphorylated FFA has an -OPO3 (2-) group on the end. When the methoxide goes to attack, the -OH would theoretically be removed in favor of the -OCH3 (methoxide) group but this reaction would result in Sodium Hydroxide being formed as a product. A weak acid and a strong base cannot result in a weaker acid and an even stronger base so this is not favorable and will not occur. With the Phosphoester, the product of the methoxide added is a Sodium salt of phosphate which is neutral compared to NaOH which is more basic than NaOCH3 (methoxide). A phosphate salt being neutral means that the reaction does take place since Na3PO4 is less basic than methoxide and the biodiesel ester is less acidic to the ffa. (a little basic chemistry) I'm sure some of you already know this but I thought I'd write it up as a note to all those who are curious. JEFF Yahoo!

[biofuel] Sustainable Agriculture ----- was: $7.5 Million Feedstock Subsidy for SSPC
The problem is that the bankers convince the farmers that they need the most modern equipment, and operating practices to compete, and any farmer who has debt will tell you that it is not fun... In my own experience, I can tell you that if a farmer wants to make money, he must not conform to what the bankers and universities tell him to do to make money, but see for himself what the animals and soil are telling him. A farmer who abuses his animals will not make any money that is obvious... but if a farmer feeds his animals high protein, high corn, low forage diets, in essence he's doing the "right thing" according to the university and banker to get the high yield in milk, or meat, but the animal isn't designed to eat that diet, it will get sick, and "burnout" so why isn't this considered abuse? Notice the dairy farms in California where they feed the hell out of the animals, give them all the modern drugs and hormone treatments, then wonder why they are culling out animals after only one year of milking, creating a huge shortage of youngstock (if the cows don't have calves, where do new cows come from?) It has been proven that a cow will give more milk with less inputs as it gets older and has more calves. But it is easier, with super large herds (and seems to be the general philosophy with large businesses) to just get what you can now and who cares if the animal's immune system goes to hell, and whether it has a heart and liver 4 times the size it should be? That's the problem with modern agriculture! Man wants it now... and will do anything to get it. To take care of your animals, and not listen when the banker/university study says you have to expand will be the best way to go because healthy animals will give you healthy milk/meat, and they will also reproduce healthily! More cows= more money, and if you can do this with less inputs, then you make money (but the key is that you have to resist the urge to borrow money and get in debt because once you're in debt, the tendency is to borrow more to get out of debt and you just get deeper. I ask you: Look for a farmer who is not in debt and tell me if he isn't making money (sure not millions, but he's making a living).

Re: [biofuel] $7.5 Million Feedstock Subsidy for SSPC
The major misconception with organic farming is what the chemical companies have to say about how it works overseas... you watch these promotion videos for Monsanto and they show how poor the crops grow in Nepal or Central Africa and they say how foolish they are for not using the most modern chemicals on the market... the truth however is much different: In the United States, it will typically take 7 years of Chemical-free farming to certify the farm organic... but what you must remember is that sustainable farming on land that has been intensely fertilized and the chemical use in general has been high, is that the soil is damaged... the soil microbes like some bacteria, and earthworms have been killed off by the pesticides, herbicides, and fertilizers used over the years, and to suddenly try to go no-input is like trying to get someone who's trying to quit heroin cold turkey to start living life normally again... I guess that's the best analogy... the idea that the chemicals used are like drugs and once the soil is addicted, the plants will only be able to take up what YOU put on them, and not be able to access the nutrients already in the soil. The transition to organic farming is a slow one, and it takes great discipline because it doesn't necessarily mean cutting cold turkey but reducing those things you use. For example, to start, there is no such thing as zero-input... that is foolish... grains and other feedstock do take from the soil... using manure, and organic fertilizers like Potassium Sulfate or Calcium Phosphate (not oil derivatives such as ammonium nitrate) will help the soil. The most common potassium fertilizer out there now is KCl which is a chloride salt of potassium... if you imagine, pour table salt on your tongue and feel the burn... that's what's happening to your soil. A plant will naturally use what it can by its own means. By putting a highly water soluble chemical fertilizer on your soil, you are in effect disrupting that balance. A water soluble fertilizer isn't the best source because the plant will take this fertilizer in with the water and in some cases, cause toxic effects in the plant. Sure, the corn won't be as green if you use more natural fertilizer _ BUT IT WILL BE HEALTHIER, and the vitamin/mineral content will be better, and remember, it isn't always the yield that makes the money because if you spend $100 per acre to get that extra 50 bushels per acre, are you really making it big if the corn price is less than $2.00 per bushel? It is all about inputs vs. outputs because the more you input, the more you must get out. And if you can put less in and get less out, but still make the same amount of money, why would you do it any other way (other than to go to the local feedmill to brag about your yields) And one last thing, it is foolish to feed all your corn to beef animals rather than to allow those animals to be healthy and pasture them. It may take longer for the animal to reach slaughter weight, but the animals will be healthier and it will be cheaper to feed them. once again input vs. output... And the surprise of all, no one ever mentions dairy, but this is the once situation where feeding corn will make money because a pound of corn will yield more milk $ than just selling the corn itself. Sustainable agriculture and dairy work hand in hand and of course, rotation of crops does is a big key. Notice how one crop grows, and in the process leaves something behind that is beneficial for another crop... and the pest problem is gone... studies have shown that even a crop like oats before corn will help increase corn yields over corn on corn on corn year after year... and sticking a new crop in the mix every year or two will also reduce the need for fertilizers because corn sucks everything out of the soil, while small grains and alfalfas take less maintenance and are good for soil organisms. Sustainable agriculture doesn't necessarily mean no input, but it means smart stewardship. Taking care of the soil because that's all you have. If you abuse the soil, it will not produce. If you take care of the soil, the soil will produce just as much as it would otherwise. In one example for my dad who is a dairy farmer in Wisconsin (I'm at college) we had 200 bushel per acre corn one year (1994), and about average yields in the past decade or so compared with those who use all the modern means of farming and all we use is dairy manure, and a good solid crop rotation. (in case you didn't know, 200 bushel corn is an enviable position to be in no matter where in the US you grow corn, not just NW wisconsin where the weather doesn't favor anything more than 100 bushel per acre corn. check out this webpage for any ideas... http://www.midwesternbioag.com --- In [EMAIL PROTECTED], Keith Addison <[EMAIL PROTECTED]> wrote: > Hello again George > > >Hello Keith > > > >I don't disagree as

[biofuel] removing water from alcohol
Hey, I know many of you on the list as well as I have been trying to find ways to dry alcohol without using zeolites, etc... there has been the suggestion of using metallic potassium or sodium (very dangerous) but what I was thinking is that maybe using a K2O or Na2O (potassium or sodium oxide - not hydroxide) to consume the water? Since when left out in the open, the two oxides will absorb water to become KOH and NaOH respectively, why not use them to make KOH or NaOH in the solution? JEFF Yahoo!

Do you realize how dangerous adding potassium metal directly to an alcohol (or water) no matter how slowly is?

I am sure you can see already the dangers of this since it would ignite the alcohol.

oilseed content - was Re: [biofuel] rapeseed seeds
Corn has a very low percentage of oil in the seed so 129 lbs over an acre where the average yield in corn is about 150 bushels or 8400 lbs makes corn only about 1-2% oil which means that it is extremely hard to extract. An acre of palm would produce that much since each tree produces bunches of close to 30-40 lbs of fruit which contains about 45% oil. just remember that trees can produce more than one "bunch" of fruit, and that there is appoximately 200 feet x 200 feet area in an acre... (43,560 sq. ft. to be exact) so that if a tree takes up 20 square feet or so, you'd have 2000 trees per acre and if each produces only two bunches with oil produced at 30-40 lbs/tree, you quickly get 6000- 8000 lbs of oil in that acre. I don't know how many trees you can put in an acre, or their exact yield, all I'm saying is that it is possible.

[biofuel] Re: canola vs. soy oil... stuff...
Keith, I have made a couple jpg files showing the basics of the iodine test. I could also attach a text file or something to explain the whole procedure, but basically, what an iodine test does, is not to show the amount of double bonds, but how reactive those bonds are (the more double bonds are broken and saturated by iodine, the fewer double bonds remain, and the reaction rate slows down) The iodine number is actually the amount of iodine consumed by an oil expressed as the amount of iodine in centigrams vs. the amount of oil in grams. The number is expressed as a percent (since dividing centigrams by 100 will give you grams) Here is a website that shows basically what the iodine test entails (this is the modern procedure in an analytical chemistry lab) http://manuals.dot.state.tx.us/dynaweb/colmates/mtp/@Generic__BookText View/150943 > > > >I could draw up a diagram and post it to the files section if anyone > >has questions. > > That would be useful, but the Files section is closed for uploads.

[biofuel] canola vs. soy oil... stuff...
I decided to do a little research on the actual chemical structure of canola, soy, and linseed oil to see how each differed and to see if the chemical structure itself has something to do with the various properties of the oil, once it is converted into biodiesel. I hope I don't confuse anyone! I am sure that most people who read this list understand what it is that makes an oil (glycerol bound to 3 fatty acids). Animal tallow/lard, is saturated, meaning that in the fatty acid portion, all the carbons are bound to 2 hydrogens, and there are no double bonds. This allows the chains of fatty acids to be straighter, and more pliable so they harden at lower temperatures (that's why lard is a solid). As you increase the number of double bonds in a fatty acid, you reduce that ability for oils to gain a conformation that would make them solid, so they remain liquid. I can explain it by imagining that you put a bunch of strings in a line. Now tie knots in various places on the strings and see how they don't fit together tightly. To test a vegetable oil to see how many double bonds (how unsaturated it is) Iodine is introduced to the oil. The iodine will attach itself over a double bond to make a single bond where an iodine is now attached to each carbon involved in that double bond. The higher the iodine number does not refer to the amount of iodine in the oil, but rather the amount of iodine needed to "saturate" the oil, or break all the double bonds. So don't worry about an oil's iodine number being high to ruin an engine because oils for the most parts contain only trace amounts of it at best naturally. How does this translate to biodiesel? When the fatty acid chains are broken from the glycerol and then re-esterified to methyl or ethyl groups, those fatty acids still have their double bonds. That means that the more double bonds, the lower the cloud point because they resist solidifying more under lower temps. It seems obvious, that if you use lard or tallow, the biodiesel will solidify at a higher temperature because the fat it was formed from also solidified at a higher temperature. How this translates into combustion, I am not really sure. It seems to me that the more saturated an oil is, the more efficient it burns (because double bonds mean less hydrogen present). A double bond between 2 carbon atoms will however has more energy when broken (meaning more heat given off when burning/combustion) The reference to epoxifiying is where a double bonded carbon is oxidized so that an oxygen atom now has a bond to each carbon (an oxygen has 2 bonds to give unlike only 1 for iodine) these are also known as oxiranes, or cyclic ethers. In laboratory, the way these are created is by using hydrogen peroxide in the presence of a zeolite. I know for a fact that epoxides can be carcinogenic, however, I know from my knowledge of Chemistry since I am studying it in college right now, that an epoxide is also extremely unstable, and if exposed to the right conditions, it will either form a diol, or a ketone. I am sure that this will also lower the amount of CO emissions in an engine. In the case of a diol (2 -OH groups), it makes that once unsaturated double Carbon bond into a saturated bond, and that raises the flash point. In the case of a ketone (a -C=O double bond), I am not really sure how it affects the chemical properties of the fatty acid. I could draw up a diagram and post it to the files section if anyone has questions. I hope this helps anyone. JEFF Yahoo!

[biofuel] hydrogen powered cars - am I missing something?
I always like to post those tough chemistry questions since I am a chemistry major in college right now, and the current one is one I believe I asked a while back, but got no response. In a car powered by a fuel cell where hydrogen is essentially the main fuel source, or solely the fuel source, what is used to burn it? It may sound like a dumb question, but the atmosphere is 80% nitrogen. If air was used to burn hydrogen, then some of that hydrogen would result in ammonia being produced. Along with the desirable water. Of course, if the oxygen used to burn were generated through hydrolysis there wouldn't be a problem there, or if the hydrogen was used in such a way that it never really escaped the engine and went back into storage as fuel (hydrolyze in some way to return it to free hydrogen gas). It seems to me that you would have to haul oxygen tanks with you, and the emissions from such a vehicle, if not burning hydrogen with pure oxygen, would have to be treated with a catalytic converter, so in the end, you've come full circle. I am not sure if ammonia and oxygen would revert to water and nitrogen gas if sent through a catalytic converter. Any ideas? Or am I totally off on my reasoning here? JEFF Yahoo!

[biofuel] Methanol/Ethanol/ and Chem research project
I don't have much scientific knowledge about this, but I would guess that since methanol is a smaller molecule than ethanol, it is probably more reactive and therefore will work better to make biodiesel even if there is more water present. Anyone else who can back this up? I might also use this opportunity to ask how well Calcium Chloride works as a drying agent for ethanol or methanol (we use it all the time in our organic chemistry lab at college so I figure it would work, but I wondered if anyone has personal experience out there with it. I thought you'd all also like to know that I'm a senior in college and I'm off for this semester (school can get very stressful if you're a chemistry major) And I went into Chemistry for the purpose of researching alternative fuels, and I have planned to return to school next spring to work on Biodiesel as a sort of research project/thesis. I'm not quite sure exactly how I'm going to go about it, but since I have made and used both Sodium Methoxide and Sodium Ethoxide in lab, I'm sure I'll do a little research on both, and if I have the equipment, I'll use a calorimeter to see what the energy levels are. Any other suggestions would be welcome. I have a until next spring to think this out. Also, I am at home on a dairy farm in NW Wisconsin, and I've talked my dad into trying out Canola as an alternative crop. If we can get a good quality oilseed expeller, we'll see how it works out.

Hi all, I thought I'd do a quick yahoo search to see if there was anything about the magnetic resonance fuel line thingys you guys have been talking about and all I could find other than a few sites that had them for sale was this one that discussed research: http://www.csicop.org/si/9801/powell.html the guy said that he couldn't find any credible research data on the technology.

[biofuel] Re: running a house from a generator
I was just thinking about the idea of converting excess energy to heat. Now if you eliminated your furnace and water heater, and ran a water heater-like reservoir off the genset instead of a radiator, then used that for a source of hot water, and maybe installed in- floor radiant heat and just pumped the antifreeze from the engine through there during the summer, you'd have enough "free" heat to heat your house. I wonder how using a small refrigerator unit would work to cool this radiant floor heating system to make it into a radiant floor cooling unit for summer. (rambling thoughts I guess) If you made your own fuel (let's say biodiesel) for cheap enough, you could run a fairly decent genset 24/7. If you were to assume that the typical 60 amp home service (@220 v.) would be about 13 kw (of course, that 13 Kw would be for peak usage, and if you cut it down to say 8 kw, and figured out a way to not have the dryer, or the oven, or some large appliance running at the same time, you could avoid this. Another way to do this could be to have 2 small 4-5 kw generators, then you could run one generator 24 hrs a day and have a switch on the other one to run at peak hours. Another rambling of thoughts... and probably not very cost effective. JEFF --- In [EMAIL PROTECTED], [EMAIL PROTECTED] wrote: > What I suggest about freezers is the good old way.

[biofuel] using an inverter
I'm curious, and slightly concerned about the use of inverters to turn DC to AC power. I've heard that the use of inverters causes extremely high magnetic/electric fields which are a cause of stray voltage (a concern here since we are a dairy farm and have paid dearly for it) and I've also heard that if you wish to use an inverter to power a house, they can damage electronic equipment. I am not sure if this is because the cheaper ones don't convert into a true sine wave but just a square wave (or if there is a high amount of feedback from the coils on those things). Stray voltage can be the cause of many illnesses and I won't go into that now... but another thing is that it is one thing to want an inverter to power a house, but how much to get the necessary equipment to synchronize the power to the grid? Just a few questions - enlighten me! JEFF Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Please do NOT send "unsubscribe" messages to the list address.

[biofuel] Re: Green Algae Producing Hydrogen : The 2nd Law of Thermodynamics
Yes, it is true that converting a starch such as corn grain does yield a positive energy balance, but what you aren't taking into account is how much energy the corn plant uses just to produce a bushel of corn (the amount is astronomical) The result of the corn's growth requires more energy than you'll get out of a couple gallons of ethanol, but since most, if not all of that energy used is actually sunlight, I guess you could call corn plants glorified solar panels, eh?

[biofuel] Re: Waste Veggie Oil in Home Heater
I'm curious as to how well waste oil (if properly filtered) would work if dissolved in gasoline, or diesel and used for fuel. How well would it work to use gasoline or diesel as a thinner to make the vegetable oil flow better and thus make it easier to burn in a furnace? Could this also make heating unnecessary, and make filtration easier since the liquid would be less viscous? Just a few thoughts...

[biofuel] using vo for hydrogen
I've read on this list that they're talking about the supply of hydrogen running out when oil runs out, but what is wrong with removing the hydrogen from vegetable oil instead? If the typical fatty acid chain on a saturated fat is 14-16 carbons, then the typical hydrogen content would be 27-31 hydrogens per chain and there are 3 chains per fat/oil molecule. I presume that since vegetable oil is an organic compound just as gasoline, and oil are, that the process would be the same, or at least similar, and the source would be renewable. But then there is a secondary problem: Hydrogen, unlike Carbon does not hold much energy in the bonds and it would take much more hydrogen to power a vehicle than it would ethanol. The only reason why hydrogen is so popular as an alternative fuel is that its exhaust is water. Another thing I was thinking about is the use of methanol or ethanol instead of natural gas in one of those liquid from gas fuel factories. Make octane from ethanol? Is it possible (or maybe octyl alcohol) Just a few thoughts... JEFF Yahoo!

[biofuel] glycerol soap waste conversion to fermentable product?
My question is directed toward any biochemists out there who would have knowledge of this idea: I have read up on the process of making biodiesel from Sodium Ethoxide (lye and ethanol) and vegetable oil, and I understand that a by-product from this reaction is a glycerine soap. My question is that is is possible to enzymatically convert this soap back to glycerol [HO-CH2-CHOH-CH2-OH] (remove the Sodium) and then convert it into a fermentable product such as pyruvate [ CH3-C(=O)-COOø ] via Dihydroxyacetone Phosphate or Glycerol 3-Phosphate? If this is the case, then all the glycerol can be converted into ethanol and create even more fuel from the process. Is the economically feasible if it could be done or would the costs outweigh the benefits? Yahoo!
