[biofuel] Deterioration of rubber by biodiesel
I've read quite a number of things referring to deterioration of rubber and certain plastics by biodiesel. How serious is this problem really? I understand that methyl ester is a pretty good solvent. I know that methanol is a really good solvent. In Aleks Kac's Foolproof method, section on methanol recovery, he says that you can remove at least one quarter of all the methanol used. Over 50ml per litre of oil. My questions are: 1) Is this much unreacted methanol present in the other biodiesel recipe's or is this unique to Aleks' foolproof one.? 2) Is it mainly the methanol which causes the deterioration, or is the methyl ester equally or more to blame. (will a good methanol recovery system help signifigantly to save rubber etc.?) Obviously this problem isn't critical, because plenty of you folks are driving on the stuff, but I'd like to understand this aspect a little better. Thanks, Dave. Do you Yahoo!? Yahoo!

Re: [biofuel] Media Coverage of Rural Issues in BRAZIL
Our beloved Kind deicated group leader Keith, observation of small farmers income are simillar and worst in Brasil and South America as the same as in the North America ,where as the big farmers here in Brazil alone is having 400 small aeroplanes built for soya protections uder utized , where as the small farmer become much poor and rich farmer become much richer in America, leading several economic problems. However here in Brasil there is good media coverage of rural technolgy well prepared so that the most of the Brazilian love to see, understand , like serial TV novels with good quality making rural media coverage and technology difusion to the remote area.Even uneducated rural small farmer understands the media coverage. The rich and small farmer all sit in sunday eraly mornig to see GLOBE TV canal RURAL media coverage .Thus Brazilian rural economy is sutained inspite of the rapid global large scale farming is trying to destroy the rural sutained economy for all to the hand only few.For you have an idea , the land of the whole rich in sugare cane and all the land of the small state like Alogoas is belonging to very few peoples (50). Because of the deicated jounalist work in rural media coverage , now the programme has been extende to all the days.Tha other Brasilian TV channel SBT too now entered , other than central govenment educational TV.Thus Brazil media is doing the best work in the rual area media coverage as already Brazil is expanding the market with the coverage of TV Novel serial not only in America but also in the most part of Europe and Russia with natural environmental built with in novels. Surely we need one INTERNATIONAL GLOBAL RURAL TV channel for the world..Keith , we in the group can think of his Global world contact here we have to move and grow into word dedicated Rural information Media forum , shaping in the format of Brazilian sucessful media coverage format , as here even the city people like to see this programme, can be made possivel in future .It depends not only our leader Keith work , but all of of us the member .This TV chanel need to be for the small for all the part of the world based onthe knowelege of our group members. Let us share our global experiences to solve the problemas as the same problem of poor becoming poor and bigger envolved in corruption to maintain the corportaion, as this can not sustain our world for long time .This TV can bring peace into the divided world of poor and rich , avoid the future terror activity of have nots. Feel free to have contact with us , we can send examples of tis rural media coverage related to fish farming ,rural house building , alcohol production, water storage , biogas , animal feed for semiarid raes , but all are inthe language protuguese .We can help to give information if any one need the this media coverage.Feel free to have contact to us for those who are deeply involved inthe small scale farmers .Our world can be made better only if we make the rural area sustainable , but not by allowing exploitation of the big farmers.

[biofuel] Air-car doesn't work
It's been discussed here a few times before, I beleve we were sceptical, mostly. But he nonetheless gets $13 million in investment for something that doesn't work. Well, at least he admits it, sort of. Other people with things that do work get nothing. - K --- Detroit Free Press http://www.freep.com/money/autonews/aircar18_20040318.htm Experimental car is powered by air Experimental car is powered by air French developer works on making it practical for real-world driving March 18, 2004 BY WILLIAM DIEM FREE PRESS SPECIAL WRITER CARROS, France -- In an industrial park a few miles from Nice on the French Riviera, Guy Negre has developed an environmentalist's dream car. Compressed air is the fuel, cold air is the only exhaust. A prototype van called CityCAT -- the sixth made by his company, Motor Developpement International s.a. -- tools around the parked cars of his staff of about 30 just as any small van might, except that the power is coming from three long black tanks in the back, full of air compressed to 5,000 pounds per square inch. No powertrain could be more environmentally attractive. It requires some up-front electric energy to compress the air, and that's all. Like an electric car recharging its batteries, you could plug it somewhere when the air pressure has fallen too low and have the on-board compressor refill the tanks. The car and Negre's invention have been on television on every continent. More than a dozen investors from Mexico, France and elsewhere have invested $13 million for 35 franchises on a future mini-factory and sales territory. The only problem is, it won't work in real life. The clean engine is insufficient to be sold, he says, after seven years of development. The air-powered car has too little power and too little range. Negre's son Cyril, an engineer at MDI, said that the CityCAT prototype goes about 37 miles on the test track before it runs out of air. However, Negre is not waving a white flag. He is simply returning to an engine he started designing in 1992 after a career designing Formula 1 engines. The air car engine, he said, will now get a clean-burning external combustion chamber so that the CityCAT can operate as a hybrid with two energy sources: running on compressed air from the tanks or burning fuel to expand ambient air, which powers the pistons. All motors are essentially compressed air motors, he said in an interview at his company headquarters. Internal combustion in a standard diesel or gasoline engine simply heats and expands air. He would not describe in detail the changes he expects to make for his new engine, except to say that the external combustion would produce tiny amounts of exhaust pollution. As for fuel economy, he said, On an early engine, we achieved 2.5l/100km (94 m.p.g.), and this one will do better than that. Negre doesn't dream small. Starting with his compressed air engine in 1997, he developed the idea of a Green Taxi for city centers. That has evolved into two cars, the three-seat MiniCAT and a five-seat CityCAT. He has an idea for a compressed air bus. To build the MiniCAT and the CityCAT, he has designed a small factory with a capacity of two cars an hour -- about 7,000 cars a year -- where workers would manufacture engines and body panels and assemble the finished product. In six to 10 years he hopes to have 400 factories around the world, 20 of them in France. In the concept, MDI will deliver the raw materials to the factories, to assure the same quality everywhere, said Negre. His dream doesn't really match the reality of industrialization, validation and government approvals. Negre's new engine with the external combustion chamber is still in the design stage. It isn't expected to reach the prototype stage until the end of this month, yet Negre is confident he can validate it and sell his first MiniCATs by the end of the year. That is unlikely. Automakers with huge resources take years to validate an engine and test its durability. Negre has a small staff and is operating on a shoestring, without enough money to return to the Paris auto show this fall. His dream has some credibility, because his air car works. Compressed air gives an adequate performance in city driving for a limited time. But MDI is a long way from taking on the big automakers. March 18, 2004 Yahoo!

Re: [biofuel] Craking
I wonder if this is similar to fat splitting? Here's a reference to page associated with the USDA (US department of agriculture) that talks about splitting triglycerides into glycerol and FFAs. I looked at the patent (US 5,932,458) at http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2Sect2=HITOFFp=1u=/netahtml/search-bool.htmlr=1f=Gl=50co1=ANDd=ptxts1=5,932,458.WKU.OS=PN/5,932,458RS=PN/5,932,458 but i couldn't make too much sense of it. it's interesting, though. one could make glycerol and FFAs in a less chemical intensive process, potentially less energy-intensive too. From: http://www.arserrc.gov/techtrans/Technologies/Fats%20and%20Lipids/techSplitting.htm NEW TECHNOLOGY A Method of Rapid Fat and Oil Splitting Using a Lipase Catalyst Found in Seeds In 1980, the U.S. produced 1.14 billion pounds of major fatty acid raw materials consisting mostly of triglycerides which, for most applications, must be split into glycerol and free fatty acids. Some of these raw materials include fats and oils such as castor, coconut, corn, palm, soybean and tallow. From 1983-1984, world production of selected fats and oils increased from approximately 56 million metric tons to approximately 60 million metric tons in 1984-1985. The major contributors to these figures include: soy, palm, sunflower, cottonseed, butter, and tallow. The American fatty acid industry splits fats using the Colgate-Emery process. In this process superheated steam is sparged into the fat. The usual conditions for splitting are 485 OF and 700 psig. The entire fat splitting operation is blanketed with nitrogen. Nevertheless, polyunsaturated fats undergo significant degradation and must be extensively purified by distillation for most uses. Castor oil contains ricinoleic acid, a hydroxylated fatty acid, at about the 90% level. The splitting of castor oil by a heat process is very difficult due to by-product formation. Finally, the Colgate-Emery process is very energy intensive, using about 340 Btu of energy per pound of oil split. An efficient and inexpensive method of rapidly hydrolyzing oleaginous materials of all types into their constituent fatty acids and glycerol has been developed. This method uses a naturally immobilized lipase catalyst created from seeds. Hydrolysis may be conducted in organic solvent at room temperature to yield a colorless, nonoxidized material. The fatty acid is produced as the free acid, rather than the acid salt, and may be removed from the lipase using organic solvent washes. Yields greater than 97% can be obtained. The process described in the patent application operates near room temperature. In the time required for complete splitting (approximately 24 hours) very little oxidation and by-product formation occurs. The lipase catalyst is prepared (activated) by grinding dry race horse oats. The organic solvent used can be removed from the product and recycled. Using this procedure, the cost of the oat seeds needed to break down a pound of oil is $0.23 (retail). Since the oats can be reused, the actual operating cost would be lower. For industrial purposes it would not be necessary to defat the oats. The process has been demonstrated to work on butter fat, soybean oil, castor oil, cottonseed oil, olive oil, palm oil, tallow, lard, and corn oil. Edible fats and oils are often extracted from seeds using organic solvents. Therefore, there should be no reason why the fatty acids produced by this procedure could not be used in foods.

Re: [biofuel] Craking
Hi Aaron These are enzyme processes. These two aren't for biodiesel production, just for literally splitting the oils/fats - removing the glycerine and breaking the fats down into their component fatty acids. There are quite a few patents for biodiesel processes using enzymes, especially by Foglia at ARS, also in Japan. They have some advantages, eg you can use isopropanol or butanol instead of methanol/ethanol to make branched alkyl esters, which have lower cloud-points than alkyl esters, and the process doesn't mind water-content. If you do it right, the lipase can be used many times. There are various forms of solid catalysts that do a similar job. But it's laboratory stuff, as yet - I don't think anyone is actually using enzymes to produce biodiesel. Among quite a few disadvantages are that it's not easily adaptible to different feedstocks, and, from our small-scale or homebrew perspective here, suitable lipase is expensive and almost impossible to get hold of - quite a few have tried, none have succeeded. There's quite a lot about enzymes and lipase in the archives, but I don't think anything will come of it any time soon. I wouldn't call it cracking though - that's not what a catalytic cracker does, as I understand it (not very well). I have no idea what Lee Sheppard is referring to. These people say they've succeeded in making biodiesel from soy oil and animal fat using a thermal cracking process: http://www.greenoasis.com/ $4,000,000 to make 1500 gal of biodiesel an hour. It requires 1000 gal an hour production to be economical, 1500 gal per hour is better. But somehow I don't think Lee will be building one of those in a hurry.

Re: [biofuel] Media Coverage of Rural Issues
Hi Murdoch, several threads here now, but taking them one at a time After conversations with my neighbours (one of whom sent city by-law officers to visit me because I had destroyed my lawn) Well, I don't know the context, but it sounds like you pursued another good idea there. I have an odd-shaped yard, and much of my property is road frontage, with essentially no back yard beyond a common services easement. So after I largely exhausted the available space in the side yard, I chose to expand into the area beside the roadway. I consulted with a friend who worked with the city, and also a small-scale gardener, and couldn't think of a reason why I couldn't grow vegetables in the city area adjacent to my property. After all, as the homeowner, the city by- laws say I'm responsible for maintaining it in a sightly manner and removing any noxious weeds from that area. When the by-law enforcement officer dropped by, she informed my vegetable garden had to go and I would have to re-sod the area. I asked her to bring me a copy of the by-law that would require that. Never saw another officer regarding this issue. snip Right now in my new home I am finding that, with all this space it is allowing me to think a lot differently, and I am contemplating minor growing in the future (beyond the watering I'm doing of my existing rose bushes so they don't die). Also there are many other things this allows me, such as putting in grid-tied solar PV (within the next few months) to complement my solar water heater (already in when I moved in), probably a small 25 mph EV for short trips, and maybe eventually some biofuel-making activity. A problem and holdup is one massive not-entirely-optional remodeling expense. One big plus is that *maybe* the solar grid-tie is going to be affordable because TEP has some sort of program, but it's not clear yet because I am so far out of the way that the TEP division might not have experience with any such effort. It is a lingering regret of mine I couldn't pick up the diesel vehicle offered for sale here in the biofuel forum recently from Phoenix, but the expenditure of money and time on a serious biofuel project (beyond attending Girl Mark's class) has to take a backseat. I do think that a biofuel vehicle will make sense for me, eventually, because a lot of my round trips are at highway speeds and 130-150 miles, and that would presently be quite an expensive EV to try to get together. But certainly, a biodiesel-electric hybrid might be worth consideration. I wonder if there are accepted practices, in your area or others, as to what one does with a bit of garden that one doesn't wish to cultivate, but which, if someone else wants to do the gardening the can keep the food? How much land does it have to be before it becomes a normal renting-out of land to a local farmer? I haven't seen much cultivation around the 'hood, but I do think that if I looked closely, there are probably a few households which do some interesting things. I'm not aware of any accepted practices. There are guerilla gardeners who plant on vacant and generally untended lots. There have been small rental garden plots for those that wish to garden, but don't have the space on their own property. If you own the land, I think you can pretty much dictate the rental price and who gets to keep the produce. I recommend that if you do choose to rent the land, that you do draw up a contract, with at least a nominal but legal fee (say $1), and specifying your requirements (e.g., use of natural compost, no pesticides or herbicides, any crops that are specifically to be planted or not planted, who owns the harvest). This should eliminate any issues regarding squatter's rights in the future in the event that this arrangement should be repeated in future years. I gather you are in a dry area. You may wish to research plants, possibly original natives, that get by on very little water. On the other hand, it seems you get enough rain to worry the drying laundry, so are you harvesting rain water? My favorite sustainable-technology thing that I've used recently, now that I've moved, has been this ancient fission-fusion-wind device called (I'm told) a clothes line. It also was installed here for me by the previous owner. I went on ebay and bought some clothes pins, some with metal, some just wood. It has some very interesting pros-and-cons. I really like the heavy loads it can handle and its effectiveness under most circumstances. There is perhaps a bit more labor involved in using it, but whatever. Sometimes it takes a bit of care, such as when rain comes into the question. Then sometimes you get an unasked-for second-washing. Then if lightning comes into the question, we must revert back to Hakan's warnings about the dangers of DC. This question has come up for me at least once. You have to do this
Re: [biofuel] Media Coverage of Rural Issues
Hi Keith snip Agribusiness Examiner article and some following text In my experience, mass media coverage is about selling advertising space, so the objective is to cover topics with the biggest audience appeal. That's what the ads managers used to tell us - the content as such is just that stuff that fills the space between the ads. Advertising pays your salaries! they'd crow, shortly before fleeing for their lives... Yes, Keith, but there are still so many that you have yet to chase from view. So long as the majority of consumers are urban, urban topics will win out. Increasingly, I find that urban and suburban dwellers have less and less comprehension of how rural issues affect them. There is some sort of blinders in effect - they think food comes from a store, and seem to have no perception of the industries that hide behind the loading dock of the local grocery store. (In more or less reverse order) Transportation, meat packing, slaughtering, animal husbandry, animal feed, rendering(!), growing crops, food preservation, storage, harvesting, planting, land and facilities preparation, planning, the fisheries, fish farming, etc. It's one of the reasons I grow some food plants for harvest, and encourage others to do the same. It isn't any expectation of becoming self-sufficient, but rather it's the awareness of the seasons, cycles, nature, the environment and our connection to all of that. Plus, a sense of independence, an empathy for our food producers, the opportunity to explore crops that may not be available at the local grocer (especially heirloom varieties), and just generally an opportunity to continue learning (goodness knows I still have plenty of that to do), push boundaries, and exposure to a time-cycle other than 9-5, Monday to Friday. I think it's going to take a lot of education before the urban majority sees beyond their chemically-produced lawns, and I don't expect the mass media to be an educational force in this area as much as a market follower. Yes... first dis-education then re-education (sorry if that sounds a bit Maoist - hopefully we can avoid Pol Pot's somewhat abysmal results). Reconnecting people can mean that first they have to become aware that what they've been disconnected from is there in the first place. Potentially at least, it's there all around them, not just way out in the sticks. As you're showing. I do hope we can be a bit more humane than those examples, though there are some people on some days I'd desparately like to try beating some sense into. City farming and community gardens, community greening projects, school gardens especially, have a major role to play in this. There are excellent projects in the US and Canada, but too often they get no official support, sometimes quite the opposite, though the benefits are widespread and well-researched. Yes, I've seen the city garden plots project come to an end here, and city officials destroy guerilla gardens on vacant plots with heavy equipment and then fence off the property for years, purportedly to avoid liability issues. And I've heard (not first-hand, but from people I generally trust on such matters) of local food banks refusing local surplus produce from farmers and gardeners because they were unsure of its pedigree or because the receipt was unpredictable. I'm quite often a bit surprised at finding fairly good rural-issues articles in the mainstream US press. It's patchy, but it is there. Michael Pollan does good work for the NYT, for instance. The Oil We Eat piece came from Harpers, which isn't far off mainstream. It can happen. But it is certainly still rare enough that I do tend to take notice when I do trip across it. I don't make a point of monitoring the mainstream media at all, so perhaps it is more widespread than I believe. Case in point. A few years ago, I grew some ornamental flowers on the city property between mine and the road. Never managed to pick one myself (my plan was to give my wife a bouquet on occasion during the flowering season). Other folks helped themselves. Last year, I planted the same area in beets, carrots and radish (all root crops). Never saw any evidence of any looting of those vegetables. After conversations with my neighbours (one of whom sent city by-law officers to visit me because I had destroyed my lawn), I have concluded that the root vegetables are safe because very few of my neighbours recognize what they are in their natural form (before they are harvested, frozen or canned or bagged and put on store shelves, forms they will recognize). Hmmm, I think I'm going to start a few extra cherry tomato plants this year, just to give away to other folks, to see if I can encourage them to start their own box gardens. I'm hoping to get some failures from a friend who is getting back into pottery to use as plant
Re: [biofuel] Media Coverage of Rural Issues in BRAZIL
A most interesting post, P.V., thankyou! But it's very late, I have to sleep now, I'll try to make a sensible reply tomorrow. Our beloved Kind deicated group leader Keith, Please, you make me blush!! Regards Keith observation of small farmers income are simillar and worst in Brasil and South America as the same as in the North America ,where as the big farmers here in Brazil alone is having 400 small aeroplanes built for soya protections uder utized , where as the small farmer become much poor and rich farmer become much richer in America, leading several economic problems. However here in Brasil there is good media coverage of rural technolgy well prepared so that the most of the Brazilian love to see, understand , like serial TV novels with good quality making rural media coverage and technology difusion to the remote area.Even uneducated rural small farmer understands the media coverage. The rich and small farmer all sit in sunday eraly mornig to see GLOBE TV canal RURAL media coverage .Thus Brazilian rural economy is sutained inspite of the rapid global large scale farming is trying to destroy the rural sutained economy for all to the hand only few.For you have an idea , the land of the whole rich in sugare cane and all the land of the small state like Alogoas is belonging to very few peoples (50). Because of the deicated jounalist work in rural media coverage , now the programme has been extende to all the days.Tha other Brasilian TV channel SBT too now entered , other than central govenment educational TV.Thus Brazil media is doing the best work in the rual area media coverage as already Brazil is expanding the market with the coverage of TV Novel serial not only in America but also in the most part of Europe and Russia with natural environmental built with in novels. Surely we need one INTERNATIONAL GLOBAL RURAL TV channel for the world..Keith , we in the group can think of his Global world contact here we have to move and grow into word dedicated Rural information Media forum , shaping in the format of Brazilian sucessful media coverage format , as here even the city people like to see this programme, can be made possivel in future .It depends not only our leader Keith work , but all of of us the member .This TV chanel need to be for the small for all the part of the world based onthe knowelege of our group members. Let us share our global experiences to solve the problemas as the same problem of poor becoming poor and bigger envolved in corruption to maintain the corportaion, as this can not sustain our world for long time .This TV can bring peace into the divided world of poor and rich , avoid the future terror activity of have nots. Feel free to have contact with us , we can send examples of tis rural media coverage related to fish farming ,rural house building , alcohol production, water storage , biogas , animal feed for semiarid raes , but all are inthe language protuguese .We can help to give information if any one need the this media coverage.Feel free to have contact to us for those who are deeply involved inthe small scale farmers .Our world can be made better only if we make the rural area sustainable , but not by allowing exploitation of the big farmers.

I was thinking the other day of some of the excellent farming-related and rural-related posts that we sometimes see here and elsewhere. And I was asking myself why we see relatively little coverage of such matters in major press-areas. And I think it's in part because city-folks, including many journalists, have little but city-issues in front of their faces. So, even though they may want to take some interest in other issues, they go with the lifestyle and issues that present themselves readily rather than issues that might make a more well-rounded presentation and might appeal to a broader range of readers. This is not to say this can't be changed in part just to try to figure out why there is (in my view) this disconnect where some challenging rural issues don't seem to get as much 4th estate coverage as I would have thought they warranted.
