Take a trip on the biobus March 20th to 24th. They will be visiting the Umpqua hotsprings to celebrate the spring equinox. The bus will be leaving the Redwood Peace Center 1040 10th Street, Arcata on thursday morning.
When Rudolf Diesel invented his engine, he ran it on peanut oil. A return to using biodiesel would reduce our need to import oil from foreign countries. Biodiesel is a fuel that can be used in any standard diesel engine without modification. It is made from renewable plants like soybeans, hemp, canola oil, cottonseed, sunflower seeds or animal fats. Hemp, a source of biofuel, is currently illegal in the United States. The technology required to manufacture biodiesel is a simple, time tested procedure. A chemical process called transesterification separates glycerin from the fat or vegetable oil. This produces two products -- methyl esters (biodiesel) and glycerin (used in soap).
Biodiesel contains no petroleum based products. There is a limited quantity of fossil fuel on the planet. According to Dr. Michael Moore, chief economist of the National Renewable Energy Laboratory says that finding oil will become increasingly difficult after the year 2020. Four countries control the majority of oil today. (Saudi Arabia-26%, Iraq-11%, Kuait-10% and Iran-9%). The United States controls 2% of the world's oil reserves. In the future, the need for renewable energy sources will become extreme. We will no longer have the option of drilling for more oil. Soybeans, on the other hand, can be grown forever. American farmers would benefit from the increased business. Since this fuel is made locally, transportation of the fuel to the consumer is easier than fossil fuel. Recently, there was a large oil spill off the coast of Spain. A world-wide switch to biodiesel would prevent ecological disasters like this. No oil tankers are needed at all for distribution of biodiesel fuel.
At the Campus Center for Appropriate Technology here at Humboldt State University they have a working biodiesel production system. They use vegetable oil from local restaurants as their raw material. The students convert this waste into a usable fuel for their Mercedes Benz. The fellow at the center says that fuel can be made for as little as 50 cents a gallon. Commercial production of fuel is more expensive. Biodiesel costs about $1.33 to $1.70 cents a gallon depending on many factors including the price of soybeans, labor costs and transportation. Private organizations and individuals are free to manufacture their own fuel for their own use. The CCAT website has step by step instruction for making your own.
Biodiesel is just one of many solutions to our energy needs. While talking to Adrian Nichols of the Redwood Peace Center he brought up some concerns that I had not considered before. "Are the soybeans grown organically?" Could a crop cause more damage thru the use of pesticides than it is worth? "If we use the land for growing fuel, will that interfere with using the land for growing food or not using the land at all?" A deeper solution to our problems would be to use mass transit, ride bicycles or walk to get where we are going. He also felt that we should put more effort into getting power from solar and wind sources.
In Iowa, a hybrid electricity generator is being run. It is a windmill with a biodiesel backup generator for use on days when there is no wind. One of the problems with wind power is reliability. Consumers of electricity demand a constant source of current. It is not practical to depend on wind power alone to satisfy our requirements for electricity. Computers can actually be damaged by fluctuation of the power source. With the hybrid wind/biodiesel system, the diesel generator would kick in when the wind power fell below an acceptable level.
The Union of Concerned Scientists is sponsoring a petition drive to clean up the air pollution from school busses. They are concerned about the health problems due to breathing the smoke from the tailpipe. "From school buses in our neighborhoods to eighteen-wheelers on the highway, diesel rigs are a serious cancer and clean air threat." -Jason Mark, Union of Concerned Scientists.
Research conducted at the University of California-Davis has shown that the cancer-causing potential of biodiesel particulate matter is 80% less than that of petroleum diesel. Biodiesel also significantly reduces most EPA targeted emissions, such as carbon monoxide, unburned hydrocarbons and particulate matter. Biodiesel is the only alternative fuel in the US to complete EPA Tier I Health Effects Testing under section 211(b) of the Clean Air Act. A copy of their petition can be found at www.ucsusa.org
In Canada, the use of biodiesel is gaining speed with the launch of the Montreal Biodiesel project in the spring of 2002, the largest municipal biodiesel project in North America.   More than 140 buses, running on different blends of biodiesel derived from animal rendering and U.S. soybeans will be studied over the next year. The project is expected to consume more than 500,000 liters of biodiesel this year.

Articles: Consumers   Green Biofuels Could Boost Canadian Agriculture, Economy and Environment Would it surprise you to know that you can fuel a bus with soybeans or canola?  That’s exactly what’s happening with a fleet of buses in Montreal and the BioBus project in Saskatoon in west central Canada.   Thanks to plant biotechnology, alternative biofuels and processes can be made more efficient and affordable to produce.  Biofuels — produced from renewable plant material — are proving to decrease harmful emissions while enabling the growth of local, environmentally friendly energy supplies.  Ethanol, produced primarily from grains such as corn, or biodiesel, made from oilseeds such as soybean and canola oil, are two renewable fuels.   Canada currently produces about 240 million litres of ethanol each year, a number the federal government has committed to increasing to 750 million litres per year by 2005 to deal with climate change challenges.  Commercial production of biodiesel is relatively small, with output by three companies in Saskatchewan and Ontario.  Biofuels are just one additional market for crops that normally go for food or feed uses.  Production costs and market prices will eventually determine end uses.  However, as ethanol production increases, so will demand for grains. Last year alone ethanol production in Canada consumed over 17 million bushels of corn. In fact, ethanol is Ontario corn’s third largest market. Agriculture and Agri-Food Canada (AAFC) scientist Martin Reaney views canola biodiesel as one way to assist meeting the country's Kyoto Protocol commitments to reduce greenhouse gases while helping farmers and promoting rural development.  This benefit will increase as more canola is produced using conservation tillage and biotech seed. He points to the experiment in Saskatoon where two transit service buses will use a 5 percent blend of canola biodiesel while two other control buses will run with conventional fuel.  Halfway through the project, the buses will be switched.  Throughout the test period, each bus will be scientifically monitored, measured and evaluated for characteristics such as emissions, fuel economy and engine wear.  Initial research conducted by Barry Hertz, University of Saskatchewan and the AAFC Saskatchewan Research Centre, has found that each ton of renewable biodiesel fuel saves five times its weight in diesel fuel.  As well, engines using biodiesel demonstrate wear rates as much as 50 percent lower than those using regular commercial fuels — effectively doubling engine life. Biodiesel is environmentally friendly, quickly degrading into natural organic material. In fact, biodiesel degrades four times faster than petroleum diesel. The major challenge facing large-scale production and commercial use of biodiesel today is production costs that are three times that of petroleum diesel.  Biotech research is underway to increase the oil content in canola and soybean crops that could make biodiesel production more efficient. In the meantime, the use of biodiesel is gaining speed with the launch of the Montreal Biodiesel project in the spring of 2002, the largest municipal biodiesel project in North America.   More than 140 buses, running on different blends of biodiesel derived from animal rendering and U.S. soybeans will be studied over the next year. The project is expected to consume more than 500,000 litres of biodiesel this year. Fleets from government organizations such as Toronto Hydro and the city of Brampton, Ontario, are also climbing onboard the biodiesel wagon. The future looks encouraging for biofuels production in Canada. Plant biotechnology companies are researching a corn with a higher starch content to accelerate the fermentation process used to make ethanol.  Another avenue is to produce genetically-enhanced enzymes, yeasts and bacteria capable of producing ethanol from virtually any plant, tree or agricultural waste. In the future, Martin Reaney points to the possibility of one hectare of wheat converting to a fuel that drives a vehicle for 7,000 kilometres.  One hectare of canola could convert to biodiesel that fuels a vehicle for 14,000 kilometres. With these kinds of statistics, it’s not surprising that governments such as Ontario’s recently introduced tax exemptions to boost biodiesel production from new companies such as BIOX Corporation.  Saskatchewan and Manitoba formally announced plans to regulate ethanol into gasoline in the spring of 2002.   For more information: Canadian Renewable Fuels Association     Copyright © 2003 Council for Biotechnology Information.

In the US, the current price for B20, a blend of 20-percent biodiesel and 80-percent petroleum, which is the way it is most commonly used, is about 15 cents to 25 cents per gallon higher than the diesel price. For B100-which is a 100-percent biodiesel--pricesrange from $1.33 to $1.90 per gallon depending on a number of factors, such as the kind of fat or oil it is made from and how much is purchased. worldenergy company http://www.worldenergy.net/ The main source for envirodiesel (r) biodiesel products nationwide.

Hempcar tour pumping biodiesel fuel
BY Matthew Marx, The Columbus Dispatch
They’re burning a heap of hemp on that road trip. But don’t freak out. On the Hempcar Transamerica Tour, it’s all legal, man. The Hempcar, a 1983 Mercedes Benz diesel station wagon, is running on biodiesel fuel made from industrial hemp, a legal product if it is grown outside the United States. Growing the plant in the United States is illegal because of another hemp product: marijuana. Some environmental advocates are driving the Hempcar 10,000 miles through 40 North American cities to promote hemp as a fuel source. Yesterday’s stop at Whetstone Park in Columbus was the 19th day of the 90-day trek. Today the Hempcar will be at the Knox County Fair. The Benz has been getting about 27 miles per gallon on the highway during the tour and is running exclusively on hemp biodiesel, which costs about $4 a gallon, spokesman Scott Furr said. “The production cost is minimal — about 50 cents per gallon — but because we can’t cultivate it in the U.S., the oil used to make the fuel has to be imported,” he said. Organizers have relied on sponsorships and donations to cover the roughly $30,000 cost of the tour. Among them is Todd Swearingen, founder of Appal Energy in the Athens County town of Amesville, who donated labor and chemicals so the travelers could process the hempseed oil into diesel fuel. His company processes all sorts of biodiesel fuels, which are made from vegetable oil or animal fat. “People assume I smoke pot because of what I do and because I look like a stoner with my long hair and beard,” he said after gingerly mixing hempseed oil with methanol, water and lye to make the fuel. “But that’s not at all what I’m like.” Hemp fuel is safer to ship and store than traditional diesel fuels, Swearingen said, because its flash point is 325 degrees. Petroleum diesel has a threshold of 120 degrees, he said. Swearingen said biodiesel likely never will be cheaper than fossil diesels, but would be about the same price. More important than the economic benefits is the minimal environmental impact of hemp biodiesel emissions, he said. “It’s 83 percent cleaner than petroleum diesel fuel.” Industrial hemp supporters say it can be used to make 25,000 types of products, including clothing and food, without significant amounts of THC, the active ingredient in marijuana. www.biodiesel.org What is biodiesel? Biodiesel is the name of a clean burning alternative fuel, produced from domestic, renewable resources. Biodiesel contains no petroleum, but it can be blended at any level with petroleum diesel to create a biodiesel blend. It can be used in compression-ignition (diesel) engines with little or no modifications. Biodiesel is simple to use, biodegradable, nontoxic, and essentially free of sulfur and aromatics. How is biodiesel made? Biodiesel is made through a chemical process called transesterification whereby the glycerin is separated from the fat or vegetable oil. The process leaves behind two products -- methyl esters (the chemical name for biodiesel) and glycerin (a valuable byproduct usually sold to be used in soaps and other products). Is Biodiesel the same thing as raw vegetable oil? No! Fuel-grade biodiesel must be produced to strict industry specifications (ASTM D6751) in order to insure proper performance. Biodiesel is the only alternative fuel to have fully completed the health effects testing requirements of the 1990 Clean Air Act Amendments. Biodiesel that meets ASTM D6751 and is legally registered with the Environmental Protection Agency is a legal motor fuel for sale and distribution. Raw vegetable oil cannot meet biodiesel fuel specifications, it is not registered with the EPA, and it is not a legal motor fuel. For entities seeking to adopt a definition of biodiesel for purposes such as federal or state statute, state or national divisions of weights and measures, or for any other purpose, the official definition consistent with other federal and state laws and Original Equipment Manufacturer (OEM) guidelines is as follows: Biodiesel is defined as mono-alkyl esters of long chain fatty acids derived from vegetable oils or animal fats which conform to ASTM D6751 specifications for use in diesel engines. Biodiesel refers to the pure fuel before blending with diesel fuel. Biodiesel blends are denoted as, "BXX" with "XX" representing the percentage of biodiesel contained in the blend (ie: B20 is 20% biodiesel, 80% petroleum diesel). Why should I use biodiesel? Biodiesel is better for the environment because it is made from renewable resources and has lower emissions compared to petroleum diesel. It is less toxic than table salt and biodegrades as fast as sugar. Since it is made in the USA from renewable resources such as soybeans, its use decreases our dependence on foreign oil and contributes to our own economy. Where do I get biodiesel? Biodiesel is available nationwide. It can be purchased directly from biodiesel producers and marketers, petroleum distributors, or at a handful of public pumps throughout the nation.

Cover Story 2/17/03 Living Without Oil As war looms, the search for new energy alternatives is all the more urgent
By Marianne Lavelle Grant Goodman wanted to do his part to reduce U.S. dependence on foreign oil. So two years ago, the Phoenix concrete producer began using biodiesel-- made from refined soybean oil--to fuel his fleet of 130 diesel-powered cement mixers and excavators. For his efforts, Goodman in 2001 won a local entrepreneur of the year award and plaudits from the Environmental Protection Agency. But protecting the Earth was not Goodman's only concern. "Let's start with national security--the billions and billions we waste dancing around the issue, protecting those pipelines, invading Iraq, doing whatever else we're doing in the Middle East. It all gets down to continuing the flow of oil to this country." Goodman's stance hasn't been easy. Biodiesel fuel sold for 70 cents per gallon more than regular diesel fuel, giving competitors of his Rockland Materials a decided edge. "It cost me a few hundred grand," says Goodman. Those harsh economics forced him last year to resort to a petroleum mix including 40 percent or less of biodiesel. But don't count him out. He plans to build his own soybean oil refinery this year to help him return to 100 percent biodiesel. Goodman has urged other local businesses to make the switch, but as long as petroleum is cheaper, he says, "I'm this guy screaming in the wind."
Hemp for Fuel Biodiesel can be made from domestically produced, renewable oilseed crops such as hemp. With over 30 million sucessful U.S. road miles hemp boidiesel could be the anwser to our cry for cheaper fuel. We have spent the last century polluting our beautiful country with our petroleum based fuels that could have easily been replaced with fuels derived from hemp. It would only take 6% of our U.S. land to produce enough hemp, for hemp fuel, to make us energy independent from the rest of the world The concept of using vegetable oil as an engine fuel dates back to 1895 when Dr. Rudolf Diesel developed the first diesel engine to run on vegetable oil. Diesel demonstrated his engine at the World Exhibition in Paris in 1900 using peanut oil as fuel. Why Hemp Fuel? Biodiesel is the only alternative fuel that runs in any conventional, unmodified diesel engine. It can be stored anywhere that petroleum diesel fuel is stored. Biodiesel is safe to handle and transport because it is as biodegradable as sugar, 10 times less toxic than table salt, and has a high flashpoint of about 300 F compared to petroleum diesel fuel, which has a flash point of 125 F. Biodiesel can be made from domestically produced, renewable oilseed crops such as hemp. Biodiesel is a proven fuel with over 30 million successful US road miles, and over 20 years of use in Europe. When burned in a diesel engine, biodiesel replaces the exhaust odor of petroleum diesel with the pleasant smell of hemp, popcorn or french fries. Biodiesel is the only alternative fuel in the US to complete EPA Tier I Health Effects Testing under section 211(b) of the Clean Air Act, which provide the most thorough inventory of environmental and human health effects attributes that current technology will allow. Biodiesel is 11% oxygen by weight and contains no sulfur. The use of biodiesel can extend the life of diesel engines because it is more lubricating than petroleum diesel fuel, while fuel consumption, auto ignition, power output, and engine torque are relatively unaffected by biodiesel. The Congressional Budget Office, Department of Defense, US Department of Agriculture, and others have determined that biodiesel is the low cost alternative fuel option for fleets to meet requirements of the Energy Policy Act.
Montana State University Communications Services Hemp: Many possibilities as an alternative crop By Jim Bauder and Linzy Carlson MSU Land Resources and Environmental Sciences Perhaps the most exciting use of hemp is in the production of biofuels, the diesel and gasoline-like fuels made from hemp oil, vegetable oil or animal fats. Once again, this is not new technology. In 1895 Dr. Rudolf Diesel invented the first peanut oil powered diesel engine and Henry Ford strongly supported using ethanol made from American grown oilseed crops, such as hemp. Wood paper and petroleum based fuels and plastics came to dominate the markets, but relatively recent concerns of smog, acid rain, health problems and dependence on foreign oil have revived thoughts of hemp's many benefits. And there are numerous advantages to hemp-derived biofuels for both gasoline and diesel engines. The following list deals with a specific biofuel called biodiesel. Biodiesel is the only alternative fuel that runs in any conventional, unmodified diesel engine. Its use can extend the life of diesel engines, because it is more lubricating than petroleum diesel fuel. Fuel consumption, auto ignition, power output and engine torque are relatively unaffected by biodiesel and it is a proven fuel with over 30 million successful US road miles and over 20 years of use in Europe. It can be stored anywhere that petroleum diesel fuel is stored. Biodiesel is as biodegradable as sugar, 10 times less toxic than table salt and has a high flashpoint of about 300 degrees Fahrenheit compared to petroleum diesel fuel, which has a flash point of 125 degrees F. When burned in a diesel engine, biodiesel replaces the exhaust odor of petroleum diesel with a smell something akin to french fries. Biodiesel is 11 percent oxygen by weight and contains no sulfur, so instead of creating sulfur-based smog and acid rain as by-products, it produces oxygen instead. Biodiesel can be made from domestically produced, renewable oilseed crops such as hemp. Biodiesel is the only alternative fuel in the US to complete EPA Tier I Health Effects Testing under section 211(b) of the Clean Air Act, which provide the most thorough inventory of environmental and human health effects attributes that current technology will allow. The Congressional Budget Office, Department of Defense, US Department of Agriculture and others have determined that biodiesel is the low cost alternative fuel option for fleets to meet requirements of the Energy Policy Act. Ask any American what environmental problems they are most concerned with and undoubtedly the response will contain mention of rapidly filling landfills, air and water pollution and the adverse affects of these factors on earth's plant, animal and human population. Ask any American farmer what needs to be done to help the flailing agricultural economy and part of the solution will probably entail integration of alternative crops into conventional farming operations. With this in mind, hemp may help provide both economic and ecological stability.

http://www.state.ia.us/dnr/energy/index.htm Hybrid wind-diesel engine energy systems are among the most popular hybrid renewable energy systems due to their relatively low capital costs and ability to provide constant power in the face of intermittent wind resources. Engine generator sets can be quickly started when wind speeds drop below levels required for wind power generation. The engine generator set provides a degree of flexibility in the choice of fuel burned. Most commonly diesel fuel is used, but this fossil fuel is a poor choice from a renewable energy perspective. However, there are three renewable fuels that can be used for stand-by power generation from a diesel engine: biodiesel oil, producer gas, and biogas. Biodiesel is manufactured from oils extracted from soybeans. Producer gas is the product of gasifying any of a number of biomass materials, including wood chips, switchgrass or other grass crops, and agricultural residues such as cornstover or corn cobs. Biogas gas is obtained from anaerobic digestion of high-moisture biomass such as manure
