[biofuel] Bacterial Batteries
The journal Nature reports that bacterial batteries may be possible. What's undecided is how mankind may exploit the phenomenon. Ted Swarts Kelowna, British Columbia Bacterial batteries clean up Researchers name the microbes that could produce power by munching pollution. 18 January 2002 PHILIP BALL The sea bed could be one big battery. Bacteria could clear up oil spills and generate electricity at the same time. US scientists have identified microbes that produce power as they digest organic waste1. The bacteria strip electrons from carbon in ocean sediments to convert it into the carbon dioxide they need for metabolism and growth. Usually the organisms just dump the electrons onto iron or sulphate minerals on the ocean floor. But the bugs will just as happily pile electrons onto one electrode of an electrical circuit. As researchers at Oregon State University in Corvallis discovered early last year, you can make a battery by planting an electrode in sea-floor sediments and leaving the other in the sea water above2. This discovery raised hopes that the seabed might be exploited as a natural low-level power source for the equipment that monitors water current and temperature, which is widely used to guide navigation. The bacteria could be put to work in aquifers contaminated by oil or sewage Derek Lovley, University of Massachusetts The Oregon team knew that the electrical energy was coming from microorganisms, but they didn't know which creatures were involved. Now Derek Lovley of the University of Massachusetts at Amherst and colleagues have identified the culprits by making sediment batteries in the laboratory and analysing the bacteria clustered on one of the electrodes. The organisms belong to the family Geobacteraceae. Lovley's team also found that some freshwater-dwelling members of the family can do the same thing. These might be put to work in aquifers contaminated by oil or sewage, Lovley suggests. Freshwater Geobacteraceae can break down petroleum in polluted groundwater on their own, but are often hampered by the lack of sufficient electron acceptors (such as the iron minerals). By providing these bacteria with an electrode that carts the electrons away, researchers could help bioremediation to proceed - and can capture a little electricity into the bargain.

[biofuel] Ethanol Plant Polluters?
Some people trying to start an ethanol plant near Oshkosh, WI are running into pretty stiff opposition from local residents, city council, chamber of commerce, etc. Their main arguements are that those of odor, impact on ground water, and quality of life.

Re: [biofuel] Solar History
The Most Rational Source (subtitle)* The aforementioned solar pioneers were only the most notable inventors involved in the development of solar thermal power from 1860 to 1914. Many others contributed to the more than 50 patents and the scores of books and articles on the subject. With all this sophistication, why couldn't solar mechanical technology blossom into a viable industry? Why did the discipline take a 50-year dive before again gaining a measure of popular interest and technical attention? First, despite the rapid advances in solar mechanical technology, the industry's future was rendered problematic by a revolution in the use and transport of fossil fuels. Oil and coal companies had established a massive infrastructure, stable markets, and ample supplies. Also, besides trying to perfect the technology, solar pioneers had the difficult task of convincing skeptics to see solar energy as something more than a curiosity. Visionary rhetoric without readily tangible results was not ell received by a population accustomed to immediate gratification. Improving and adapting existing power technology, deemed less risky and more controlled, seemed to make far more sense. Finally, the ability to implement radically new hardware requires either massive commitment or the failure of existing technology to get the job done. Solar mechanical power production in the late nineteenth and early twentieth centuries did not meet either criterion. Despite warnings from noted scientists and engineers, alternatives to what seemed like an inexhaustible fuel supply did not fit into the U.S. agenda. Unfortunately, in many ways, these antiquated sentiments remain with us today. *Excerpts copied from; History of Solar Energy รท Revisiting Solar Power's Past By Charles Smith Technology Review: July 95: Solar Power http://www.solarenergy.com/info_history.html Yahoo!

[biofuel] Re: Ethanol Plant Polluters?
My guess would be that the odor comes from the Drying process after the grains are used for fermentation. There is a noticable scent in the air even with small quantities. Small amounts of ethanol remain in the grain until it is air dried. There may be recovery systems available to capture and utilize this in large commercial operations. Then there is the waste water of the mash that is distilled away from the fuel. It is sometimes sent to a lagoon for storeage. The coolant water is sent to a similar lagoon. If proper facilities are not built with large scale operations a ground water issue might be present. But ethanol is 100 percent soluble in H 2 O and also naturally occuring in the open environment and inside a human body in minute quanties so I cant see it as being that high of a risk factor. My opinion anyway. --- In [EMAIL PROTECTED], Harmon Seaver [EMAIL PROTECTED] wrote: Some people trying to start an ethanol plant near Oshkosh, WI are running into pretty stiff opposition from local residents, city council, chamber of commerce, etc. Their main arguements are that those of odor, impact on ground water, and quality of life.

Then there's this: Earth Has More Oil Than Previously Estimated RESTON, Virginia, March 24, 2000 (ENS) - The latest U.S. Geological Survey (USGS) assessment of the world's oil and gas reserves estimates there is about 20 percent more undiscovered oil than previously believed. The agency also reports a slight decrease in estimates of undiscovered natural gas. The USGS World Petroleum Assessment 2000 estimates the volume of oil and gas, outside the U.S., that may be added to the world's reserves in the next 30 years. There is still an abundance of oil and gas in the world, said Thomas Ahlbrandt, USGS World Petroleum Assessment project chief. Since oil became a major energy source about 100 years ago, about 539 billion barrels of oil have been produced outside of the U.S. We now estimate the total amount of future technically recoverable oil, outside the U.S., to be about 2120 billion barrels. The assessment indicates that there is more oil and gas in the Middle East and in the offshore areas of western Africa and eastern South America than previously reported. There is less oil and gas in Canada and Mexico, and lower volumes of natural gas in the Former Soviet Union. The USGS World Petroleum Assessment 2000 is the first report to provide a rigorous geologic foundation for estimating undiscovered energy resources. The results have implications for energy prices, policy, security and the global resource balance. These assessments provide a snapshot of current information about the location and abundance of undiscovered oil and

my two cents is that I catalytic converter on my vw rabbity and it totally eliminated the smell of the biodiesel until I put a few tanks of dinodiesel thru it and killed it (sulfur poisoning, I think). I think in a stationary application, which would be 100% biodiesel (no need to take a long trip and get stuck buying dinodiesel) and a more constant operating speed and longer run times ( no short in town trips) the converter should last a long time. Also, if you are going to use a heat exchanger on the exhaust, you would be using the waste heat energy from burning the waste products in the exhaust, as in a wood stove with a catalyst. anton -Original Message- From: kirk [mailto:[EMAIL PROTECTED] Sent: Wednesday, January 23, 2002 10:52 PM To: biofuel@yahoogroups.com Subject: RE: [biofuel] Irish inventor says he's cracked world's energyneeds A high compression diesel, water cooled, with 20 feet of double wall heat exchanger on the exhaust.

[biofuel] Re: More WVO Refining experiments
Pu241 wrote: Interesting chemistry there! Any idea how the FFA are removed? Bound to the calcium silicate matrix somehow I presume! CaSiO3 is really CaO.SiO2. I believe the CaO actually acts as a base, saponifying the FFA's into the insoluble silicate crystal. I know research was also done on using Na2SiO3 and its variants (i.e., waterglass), but I didn't have much luck with that. The Celite Corp. actually does offer a MgSiO3 oil treatment powder (Celkate) but it seems to be intended to remove coloration more than FFAs. Wonder if a calcium meta silicate may work as well! Natural mineral, Wollastonite, much cheaper, cents/lb. As you said Talc, magnesium silicate is also cents/lb. Have you tried Talc? No, but these are all fine ideas to pursue... Wouldn't think the Ca vs Mg would make much difference! I have acess to both talc and wollastonite, both in commerical grades and very clean, made for the plastics industry. Material can be had in several partical sizes! Let us know! Just thought about zeolites (Magnesiun Aluminium silicates) or even clays (complexes of NA,K,Na,Mg,Al silicates) All wonderful materials which I'm already using in other areas. If you really want to make your head hurt, think about using any or all of these very same materials as basic solid catalysts to do a transesterification reaction without standard alkali OR acid.
