Re: [Biofuel] BioButanol replaces gasoline
For use as solvent, I suspect it's going to have to be of higher purity, to avoid possible contamination - that will drive up the price right there. If the plant works out, that will help bring the price down of even solvent grade. Greg H. - Original Message - From: Paul S Cantrell To: Biofuel@sustainablelists.org Sent: Thursday, December 15, 2005 12:02 Subject: Re: [Biofuel] BioButanol replaces gasoline From the first URL:"Butanol currently sells for about $3.70 per gallon in bulk (barge) and $6.80 in 55 gallon drums."and"Our preliminary cost estimates suggest that we can produce butanol from corn for about $1.20 per gallon, not including a credit for the hydrogen produced. This compares with ethanol production costs of about $1.28 per gallon. Taking into account the higher Btu content of butanol, this translates to 105,000 Btu per dollar for butanol and 84,000 Btu per dollar for ethanol with corn at $2.50 per bushel. As a further point of reference, butanol produced from petroleum costs about $1.35 per gallon to manufacture."With US wholesale gasoline (ie barge) at ~$1.65 (Source: NYMEX for January delivery), $1.20 per gallon production sounds great, especially against $1.35 per gallon from petrochem. But if the (bio)Butanol would be worth $3.70 as a solvent, would the price as a fuel be low enough to replace gasoline? I think only if the supply outstripped demand to a large degree.

[Biofuel] two stage proccess... doubts
Hi Mike,Hi Joe, I am completely agree with you on point one,Mike,I`v experienced it on my own neck.Point two-you are right about silica,but I gave it up-it is a mess when it comes to recovering the stuff;nevertheless it is useful to absorb any water content leftover,just pump it trough the vessel with silica long enough. Point 3 -heating always helps! Point 4 -I am not American,I dint know what ISA means-isopropil alcohol? Point 5 -I closed the circle too-I am using a small Rielo burner/3l/h/8bar/ to heat everything including the room with two SS pipes spiraling around the flame for heat exchange-the first is circulating oil for higher temp/distilling glycerin/ and the second is with water for heating all vessels.Did I mentioned that I put rock wool insulation everywhere. There is one more thing-I made the reactor and the dryer airtight, capable of vacuum and pressure, so I can work at temp well over 70 degrees C and put under vacuum when evaporating is necessary (and not to worry about any methanol fumes!). I started researching the so-cold co-solvent processing with tetrahydrofuran-I`ll tell you guys,it is an expensive stuff!The only plus is that it can be recovered almost completely.I`ll keep you informed how far I am trough. I will fully support the idea to co-experimenting and sharing the results-just tell me what I can do to help! Good luck to everyone! Rumen __ Do You Yahoo!? Tired of spam? Yahoo!

[Biofuel] Process details -was two stage procces... doubts
Great news Rumen and thanks for the offer; Ok; for starters, and with regard to reducing the wash cycles here is what I learned last night. Two hours after the first wash was turned off, I drained one liter of wash water ( I use 4 liters to wash) and set the beaker aside overnight. My thought was that the water still probably contains lots of tiny droplets of biodiesel and draining it too early will waste fuel and add biodiesel to the waste stream. This only really counts on the first wash because I reuse my second and third water, but how long to wait?? So in the morning I checked to see how much biodiesel had collected on top of the water. I would estimate it was less than 1 ml. I think this would indicate, at least with my setup that the first two washes could be done in as little as four and one half hours. The final wash should be well settled to reduce drying time but with vacuum drying it is so much shorter than natural air drying that a little extra water content won't make a huge difference if you have a vacuum pump with decent throughput. I am using an Edwards 18 which according to the charts should give me about 3 liters per second at 28 Hg vacuum. It has seen it's days so perhaps it is only doing 1 liter per second. BTW I am using SVO (rapeseed oil) as the pump oil, works great! Coincidentally it also takes about 2 hours to warm the contents of my reactor from 18 C to 50 C so perhaps I could re-warm the reactor while the final wash is settling, and then see how long it takes to dry after that. On the other question about traces of glycerin, due to small plumbing details I am still not happy with (and will soon fix) I know I had some traces of glycerin left before the first wash. It is difficult to estimate but I could guess it is a few cc's probably less than 5. I have a 25 liter batch size so this is like 200 ppm glycerin worst case. This did not affect the first wash significantly. but I let the batch settle overnight and cool. I would really like to know what would happen if I washed after only settling for a few hours. Another thing I am curious about is whether or not it is better to keep the reactor warm throughout the entire process, which wouldn't cost much in electricity if the cycle time is around 24 hours. I don't know if this is possible though. What is the opinion of the greybeards on the list? What type of washing are you doing Rumen? I am pump washing and I find now I can be rather aggressive with it as long as I get a good complete reaction. Problems with the wash in early batches turned out to be poor or incomplete reactions. Now that I am using my little titrator I think I am more accurate. Hand agitated titrations always resulted in oil settling out in the bottom of the test tube and I don't think I was getting good accuracy. Now everything is so well agitated that I don't see oil dropping out of the titration and my washes are very easy now. :) Let's see what we can find out about minimizing settling times on the wash process first and then we can tackle the settling time for the reaction. Rumen, how often do you make a batch? I can do one every few daysI think my biggest obstacle is time spent in the publolbut hey I have to show my gratitude for the oil right?2xLOL BTW I'm working on a BOM for my reactor which will be an excel spreadsheet with links to data sheets where applicable for parts. I'll eventually see if I can draw up an auto cad drawing for the frame etc. and get it all up on my site, in case anyone is interested.

Re: [Biofuel] Steam hybrid from BMW to enter market with 'Turbosteamer'
Although it doesn't specify, I would suspect that this is a turbine design, not a piston design. I've seen a 30kW steam turbine that wasn't much larger than an AC compressor for a car. Add a heat exhanger in the exhaust manifold, and it could be quite compact. Of course it was also noisy enough to hear from a good 200 feet away, and would require a geared stepdown drive to provide useful torque -- I think it ran at 20,000 rpm or something?

Re: [Biofuel] How long can WVO sit before transesterification
Hi Marty and Mike, Oil can go rancid like butter but it takes a long time. It can get surface growths in about 3 months at room temperature. These are usually very thin mixtures of bacteria and fungi. They are aerobesrequiring oxygen. The carbon to nitrogen ratio isastronomically high so there should only be a thin skin of biomass floating on the surface that is easily skimmed off. Oxygen transfer into SVO should be really bad too, limiting growth.Longer periods of time say 6 months to several years and the anaerobes will have a chance to do some damage but they run into the same carbon to nitrogen ratio that limited the aerobes. In addition they will reside a little distance below the surface or directly on the bottom. They are essentially surviving on the nitrogen and phosphorus released by the dead aerobes. Most of the oil will remain undecayed but may smell like goats or rancid butter. It should process just fine with some filtering. ( Coffee filters should be okay)One last thing is keep it out of the sun. The light can cause algae to grow and pretty soon you have a thriving but smelly community.

[Biofuel] A global public opinion survey shows people losing faith in governments
RIGHTS:Who Do You Believe In Any More?Sanjay Suri LONDON, Dec 15 (IPS) - A global public opinion survey shows people losing faith in governments, business and even non-governmental organisations. The survey showing "an alarming picture of declining levels of trust" was conducted for the World Economic Forum, to meet in Davos in Switzerland next month, by GlobeScan, a public opinion research firm, and is based on interviews with more than 20,000 people in 20 countries. "What the survey shows is people losing faith in a whole range of institutions," Mark Adams from GlobeScan told IPS by phone from Geneva. "This is very worrying for the world community." The Russian government is now the only institution in any country polled to have consistently increased trust since 2001, the survey shows. Trust in government has fallen the most in Brazil, South Korea, Mexico, Canada and Spain, followed closely by Argentina and the United States, the survey shows. In Nigeria trust in the national government fell by 13 points while trust in all other institutions rose. "Even in countries such as Britain and India, where trust remains positive, it has suffered its biggest fall since tracking began in 2001," the report says. "Only in Italy, Indonesia and France has trust in the national government held steady, although polling was completed prior to the recent riots across France." The poll also reveals that public trust in the United Nations has fallen over the past two years. The survey shows that trust in a range of institutions has dropped significantly since January 2004 to levels not seen since the months following the Sep. 11, 2001 terrorist attacks. "The report shows that the cement which holds world institutions together is coming adrift," Adams told IPS. The loss of faith could partly be a consequence of globalisation, he said. "In the cosy world of 30, 40 years back, people relied on governments and companies to do everything," Adams said. "But it's now a more complicated and dangerous world out there." Governments and companies "are themselves struggling to come to terms with a new world order," Adams said, which suggests that these are no longer the firm edifices people had come to lean on in earlier times. Among the highlights of the report: - Public trust in national governments, the United Nations and global companies is now at its lowest level since tracking began in January 2001. - Since 2004, trust in government has declined by statistically significant margins in 12 of the 16 countries for which tracking data is available. - The UN, while continuing to receive higher trust levels than other institutions, has experienced a significant decline in trust from 2004 levels in 12 of the 17 countries for which tracking data is available, suggesting an impact of the scandal over the Iraq oil-for-food programme. - Public trust in companies has also eroded over the last two years. After recovering trust in 2004, it has since declined for both large national companies and for global companies. Trust in global companies is now at its lowest level since tracking began. - NGOs remain the leaders in trust, but they also have to contend with some decline. In 10 of 17 countries for which data is available, trust in NGOs has fallen since 2004, in some cases sharply, as in Brazil, India and South Korea. "This is a wake-up call for the World Economic Forum meeting at Davos in January," Adams said. "If we do not regain the trust of people, the world will become ungovernable." People feel "rightly or wrongly that systems are not delivering," he said. The World Economic Forum will have to find creative ways of addressing this problem, he said. The survey involving a total of 20,791 interviews was conducted between June and August 2005 by research institutes in each participating country, under the leadership of GlobeScan. The survey asked respondents how much they trust each institution "to operate in the best interests of our society". ___ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/biofuel_sustainablelists.org Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (50,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/

Re: [Biofuel] BioButanol replaces gasoline
I didn't read through the butanol links carefully, but I know one of the problem with producing it in the past is that butyric acid (the carboxylic acid of the alcohol) is produced. Butyric acid is very bad for the environment.

Re: [Biofuel] Steam hybrid from BMW to enter market with 'Turbosteamer'
Zeke Yewdall[EMAIL PROTECTED] 12/16/05 3:01 PM Although it doesn't specify, I would suspect that this is a turbine design, not a piston design. I've seen a 30kW steam turbine that wasn't much larger than an AC compressor for a car. Add a heat exhanger in the exhaust manifold, and it could be quite compact. Of course it was also noisy enough to hear from a good 200 feet away, and would require a geared stepdown drive to provide useful torque -- I think it ran at 20,000 rpm or something? I would be very interested in finding out more about this steam turbine, for another project. Is the KW rating the HP equivalent? Can you point me in the right direction? joea ___ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/biofuel_sustainablelists.org Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (50,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/
Re: [Biofuel] MadCow additional- Organophosphates, manganese, autism, Mark Purdey, BSE
http://en.wikipedia.org/wiki/Scrapie In any case, the fact that prion diseases predate insecticides by decades is pretty compelling evidence they aren't the causitive agent. jh As a newbie on this list, I had hoped to lurk for some time, without nosing in. But . . . Without supporting or deprecating any view on this matter, I cannot agree that it is compelling that they are not the causative agent. There can be many causative agents for illness and injury. A broken arm can be caused by a fall, an auto accident, or being struck with a baseball bar, for example. That being said, it is entirely possible that addtional factors, while not causative may be helpful, in that they interfere with normal immune processes, or enhance the ability of a virus or other nasty to defeat its natural antagonists. joea ___ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/biofuel_sustainablelists.org Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (50,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/

David David, Yes I would think so, too. I would have expected more of a 'boost' to fuel economy than 15%. It must add some weight. The main weight of a steam engine is it's boiler, since this is replaced by a heat exchanger, this and the steam piston(s) will be the major weight gainers. I'd like to see it implemented in a diesel. You realize, of course, that there would be quite a bit less energy available in the exhaust of the diesel, and that the diesel already weighs a lot more than the gasoline engine, right? :)i That said, combined cycle generation has the potential to save quite a lot of energy overall in cases where weight really doesn't matter. --- (another) David ___ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/biofuel_sustainablelists.org Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (50,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/
