- Ethanol – Where Can I Find It?
Matthew Keegan asked:The growth of the ethanol industry has been a slow process, one where the automakers are way ahead of the game, building cars, trucks, vans, and SUVs which can run on either straight gasoline or a mixture of gas and ethanol, flex fuel vehicles (FFV) that now number in the millions. Lagging far behind are the number of available pumps able to dispense E85 fuel — which is a mixture of 85% ethanol and 15% gasoline — the most common blend being marketed.
Where Can I Find Ethanol?
Ethanol fuel is currently available across the US except in six states which are: Hawaii, Alaska, New Jersey, Rhode Island, Vermont, and Maine. To date, more than 1400 locations are dispensing ethanol fuel, but the majority of them are in the corn growing states of the upper midwest. As ethanol is currently derived chiefly from corn, those states producing this grain are also the ones pushing the hardest to see that ethanol succeeds. Unfortunately, ethanol’s capacity is woefully limited, especially outside of those states.
The U.S. Department of Energy tracks the spread of ethanol pumps on its website at http://www.eere.energy.gov/afdc/ethanol/ethanol_locations.html – There, visitors can view a map of the United States and click on their state to find where pumps are located. That list offers the name of the station, its address, type of access (public or private), and you can click on a link to a map that will show you where it is located.
In some cases, consumers are searching the internet themselves to find local E85 stations and comparing prices online. Please note this: even if E85 prices are 20% lower than the price of gasoline where you live, you probably will pay more for fuel over the long run. This is due to E85′s inefficient nature – you’ll achieve better performance by using this fuel, but it comes at a price. Specifically, running any car on E85 means a net increase in fuel consumption upwards of 30%.
Other Options For E85?
Because E85 is much less efficient then straight gasoline, there is a movement underfoot to sell different blends of this fuel to consumers. In Kansas, for example, one company is selling E50 fuel which is a 50-50 ethanol-gasoline blend. Government subsidies and introductory specials are keeping prices competitive, offering perhaps the best option for drivers.
Ultimately, thousands of more pump locations need to be set up across our country in order to make ethanol a viable option. Other methods of developing ethanol, cellulosic for example, can help drive down the cost which would make choosing an ethanol blend a wise one.
Until then ethanol is only widely available in four states and in blends that are simply fuel inefficient. True, the environment benefits every time a driver chooses E85, but with fuel costs at a higher amount than straight gasoline, few cash-strapped consumers will make the switch.

- Fuel Efficiency of Ethanol – What Are the Benefits of Using Ethanol?
Jonathon Winburg asked:If you drive a big vehicle like a Chevrolet Suburban you might consider the benefits of running it on ethanol. Most Suburbans that were manufactured in the past five years are flexible fuel vehicles that are capable of running on this type of alternative fuel.
Chances are good your Suburban costs you approximately $150 to fill at the gas station. This tank might get you in the city 300 miles if you are lucky. The fuel efficiency of ethanol provides a more affordable price per gallon at less than half. You might pay $70 to fill your tank with ethanol. In addition, you will also get over 350 miles to the tank. Not only will you save a lot of money when you use ethanol but you will not have to fill up your tank as often.
Another benefit you will benefit from is by running your vehicle with cleaner fuel. Gasoline burns very dirty. The fuel efficiency of ethanol burns clean with very little or no emissions at all. Although, you do still need to run engine oil in your vehicle when you use ethanol. The good news is you won’t have to change your oil as often anymore. Every time you check your oil you might find that it is clear and not black. Because ethanol burns so clean this means less maintenance on your vehicle also. You will have fewer problems and save money this way too.
The fuel efficiency of ethanol provides many benefits that are insurmountable. You already might be driving a vehicle like a Chevrolet Suburban and could really use the money in your pocket. Your vehicle will last you much longer by running cleaner and need less maintenance.

- How To Make Ethanol – The Secrets Of Making Ethanol
Allen Walker asked:Making ethanol is something that has grown in popularity over the last few years. If I were to guess it would be the record high oil prices doing the job, but that’s just my opinion. Much more of those high prices and there will be a number of people making ethanol in their own backyards.
Making ethanol is something that has actually been done for centuries. There were traces of alcohol found on a piece of pottery that is over nine thousand years old. It took until 1796 for the ethanol that we know today to be created. Johann Tobias Lowitz happened upon this by filtering distilled ethanol through charcoal. So obviously people have been making ethanol for quite some time. It wasn’t until we kept hearing the words oil shortage over and over again that we finally took action to try running it in our engines.
Ethanol is actually nothing more than moonshine. The same moonshine that was illegal in the days of prohibition is now being mass produced to power vehicles. I always thought people were kidding when they said that you could run a car on moonshine. Turns out that they were onto the right idea all along. Those that made moonshine probably didn’t know that they were really making ethanol. Actually the only difference between the moonshine that is created in backyard stills, and ethanol, is an additive. Without that additive those who made ethanol would have to pay alcohol taxes on the ethanol that they produce. But with an additive, such as gasoline, they are out of the alcoholic beverage category and into the gasoline category.
When making ethanol you will need basically two things aside from a little know how. You will have to have a working still and some corn. Actually you can use other grains such as barley or oats but many people use corn because of its high abundance. Once you have your still you will need to ground the corn or other grain so that it looks like corn meal. Place the meal, along with some enzymes, into your still with some water so that you have what looks like a watered down corn bread mixture and turn up the heat. When making ethanol you will have to turn up the heat on your still so that this mixture is on high heat.
When the time is ready the mixture will need to be removed from heat and thoroughly cooled. This is necessary for all the elements to work together properly. Yeast will also need to be added so that the fermentation can completely take place. The mash will need to be allowed to ferment for forty to fifty hours and stirred occasionally. Finally you will strain out the grains, leaving the liquid to be a nice alcoholic mixture, Ethanol.

- 6 Steps To Making e85 Ethanol At Home
Frederick Musser asked:Step One: . . . The Conversion Process
We have to break down carbohydrate sugars, such as the starch from corn. Create it into “Mash”. Grind or crush the feedstock (corn, soybeans, wheat, etc…). Then dilute and add an enzyme (alpha amylase) to turn the mixture into a liquid. Once liquified a second enzyme is added(glucoamylase) to convert the starch into sugar. (If the source is mainly sugar, i.e…rotten fruit, molasses, etc…, the conversion step can be skipped.
Step Two: . . . Fermentation
Add yeast and make it into a beer (wine) type solution.
Step Three: . . . Distillation
The beer (wine) type solution needs to be run through a still to extract the alcohol from the solution.
Step Four: . . . Filtration
The ethanol now needs to be filtered to get rid of excess organic volatiles.
Step Five: . . . Dehydration
The ethanol needs to be “dried”. After the distillation process there will be a certain amount of water in the ethanol you have just created – this can be dried running the ethanol through Zeolite a readily available product for drying ethanol.
Step Six: . . . Ethanol Into e85
Now simply convert the pure ethanol into e85 by adding 15% unleaded gasoline to your ethanol. e85 is nothing more than 85% ethanol mixed with 15% gasoline.

- Cannabis DNA Modification for Use to Produce Ethanol
Lance Winslow asked:Cannabis of course is known as marijuana and pot. It is associated with drug users and stoners. But if we can put away that stigma, we find that cannabis has four times the cellulose value as corn, making it a potentially good plant for ethanol production.
Now then, personally I do not do drugs or smoke pot so this article is without consideration of the stoners in the world or their potential support of this plant for ethanol. If cannabis grows so well all over the world it does make sense to look into its use for the making of ethanol.
If cannabis can be made into Ethanol then we need to modify it to make it work better and use those genetic differences which allow for low water in production to insure that we do not get price spikes in times of drought in the ethanol we use for fuel. Additionally if the plant can be used to “get high” then we need to modify it so that will not occur or that the leaching into the soil or waterways does not contain high levels of THC as it would be problematic.
If we further modify this cannabis weed then we need to make it with terminating seeds until we know what we have done, other wise it will become a “super weed” and take over natural cannabis and other close genetic species of weeds. In an online think tank recently a gentleman mentioned that;
“Ethanol/bio diesel is going to be the fuel source of the future for the rotary, eccentric crank, 4 and 2 cycle engines that run our cars boats trains and generator sets etc. I understand it burns far cleaner than the crude oil based hydrocarbon heavy fuels we use at present, and will minimize the pollution.”
So, it seems that we have another potential plant for cellulose ethanol production and this is a good thing, as the more options available the better for our goals in growing a percentage of our own fuel. So consider this in 2006.

- Home Ethanol Production – How is Ethanol Good For the Environment?
Jonathon Winburg asked:Ethanol is a clean burning fuel that barely burns any toxins into the air. Gasoline burns carbon dioxide into the air and harmful emissions that are responsible for the increase of global warming. It actually can reduce carbon monoxide emissions as low as 30%. As a matter of fact, it is the cleanest burning fuel on the market today. Home ethanol production is an excellent solution because you are making a clean fuel.
Harmful toxins are often emitted into the air through tailpipes causing fine particulate matter to go into the air. You can stand right in front of a tailpipe and breathe in the air of a vehicle running ethanol and it will not harm you at all. This is because there is nothing harmful coming out of your tailpipe anymore.
Ethanol is biodegradable. This means that you can accidentally spill it and it will not be harmful to the environment. It will not kill plants or cause water pollution. This is because it is made from natural elements. It is also not harmful to you if you spill it on your clothes or get it on your hands. This is what makes home ethanol production so safe.
Home ethanol production is an excellent solution to giving back to your environment in so many ways. There are thousands of people who can begin using ethanol today and stop emitting harmful fumes like carbon monoxide into the atmosphere. The emissions are clean and not harmful to the environment because they are biodegradable. Ethanol cannot harm you either if you touch it or if you inhale the fumes from the fuel.

- Ethanol Still – Discover How to Make an Ethanol Still
Allen Walker asked:Many people are wanting to learn more and more about how they can make their own ethanol. Basically you will need two very important things. Corn and an ethanol still. Of course there are other grains that you can use aside from corn but corn just happens to be grown in more places and so is a little easier to access. With gasoline prices reaching all time highs once a month it seems, the thought of having your own ethanol still to make ethanol just seems like good logic.
People have been making ethanol for centuries in ethanol stills that they constructed out of what they had. The ethanol that we know today was actually created way back in 1796 by filtering distilled ethanol through charcoal. Johann Tobias Lowitz discovered this process and if he knew what he would be doing for so many people two hundred years later, I bet he would be thrilled. Actually he probably would have celebrated by drinking a little of his creation after it went through his ethanol still. Ethanol, or ethyl alcohol, has been made in backyard ethanol stills for decades. But it had a different name then. Then it was referred to as moonshine, or by some, white lightening. Moonshine was illegal in the days of prohibition but that didn’t stop those who loved their brew. They would make an ethanol still and hide it in the woods so that it wouldn’t be discovered. Some were lucky and never got caught while others had to face jail time. Men of all ages would make moonshine runs with cars that had to be fast so that they could outrun the law if need be. How times have changed. And people always said that you could run a car on moonshine, I just thought they were joking. Who’s laughing now?
An ethanol still is a very important part in the making of ethanol. In days gone by people would put together any type of contraption they could so that they could make their homemade ethanol. Now ethanol stills have been perfected so that they do just what is needed. There is still some disagreements as to which material is better to use. A lot of people prefer to use copper for the ability it has to heat evenly all over. Others like to use stainless steel for its corrosion resistance with each party assured that their way is the best. A lot of commercial stills are made out of copper as they want the uniform heating ability that is necessary to make it the same each and every time.
The ethanol still is necessary to heat the corn mash mixture but once its job is complete the mixture will then be transferred to a fermenter that will allow the mash to ferment. This is the place that the ethanol is made. Fermentation is necessary for proper ethanol production.
Having an ethanol still is going to be something that more and more people will see necessary. Many are starting to feel the crunch of the high gas prices and soon will have to do something different in order to live like they have been accustomed to.

- What is Ethanol Fuel and How Ethanol Fuel Works – Environment Friendly Fuel
Sanjay Kak asked:One of the alternative fuel sought for oil or gasoline is Ethanol fuel . Any feed stock, which is based on carbon and after going through conversion process gives Ethanol. There is long list of carbon based items, such as sugar beets, corn, sugar cane, switch grass etc. The Ethanol fuel came in picture as clean alternate fuel and is environment friendly.
Currently Ethanol fuel is used as blend mixture with gasoline and is common at pump station across north America. It is also being used as oxygenate additive for gasoline and replacement for MTBE ingredient. The MTBE is a fuel compound which is responsible of contamination of ground water. Many states in America have put ban on use of MTBE and is being replaced by Ethanol.
Advantages of Ethanol fuel
The Ethanol fuel is a renewable, safe fuel and it can be used in cars with few modifications in car engine. Since crops such as corn, maize and sugar beats are used in making Ethanol fuel, it provides stable market to farmer community. This can be developed in any country without dependence on oil producing nations. The fuel is environment friendly.
Disadvantage of Ethanol FuelThe cost of producing Ethanol as fuel is high, more research is needed in this regard. Although research is underway, the Ethanol fuel burns more for same distance as oppose to gasoline. Since Ethanol fuel is based on crops, vast land is needed to cultivate the crops and it puts pressure on other crops which are needed by humans for daily consumption. The waste product from ethanol production is toxic

- How Ethanol Car Engines Work
Craig F Stevens asked:Ethanol cars work in a way very similar to normal gasoline cars, and are a great viable alternative fuel option because of current high gas prices. The only real difference is that ethanol car engines are able to utilize the biofuel ethanol instead of oil based gasoline.
Ethanol fuel itself is extracted from plants such as corn or sugarcane, and refined into an alcohol. This alcohol is suitable to be used as a biofuel in cars and other vehicles. Most hybrid automobile engines that use ethanol can also use gasoline, and are also called “flex-fuel” engines. The ethanol is injected into the engine in the same way as a non-hybrid automobile engine. Though ethanol gives slightly less miles per gallon than gasoline, it doesn’t create as much air pollution when it is burned.
The similarities between ethanol “flex-fuel” engines and standard engines make ethanol cars cheaper than most alternative or hybrid vehicles, because they are built in much the same way as a regular engine. Ethanol is actually cheaper in some cases than gasoline, and thus a hybrid that runs on ethanol can be less expensive to operate than a gasoline based vehicle.
Most standard automobiles can even run on a 10% mixture of ethanol in gasoline. Many gas stations around the world offer ethanol as an alternative to gasoline, and in some countries cars are required to run on ethanol.

- Understanding Bioalcohol and Ethanol Alternatives
Levi Quinn asked:When it comes to the various types of fuel available for operating vehicles, it can be more than a little confusing. We all hear several terms and phrases used on TV and in the news but when you have no personal involvement; it’s hard to really understand it all. Ethanol is a word that most of us have heard many times. However, bioalcohol is a new term to most people. These are both viable alternatives to the regular petrol fuel most drivers are consuming today.
Bioalcohol is alcohol that is derived from natural resources, similar to ethanol. It does not come from petroleum in any way. It’s just one of the latest alternatives being considered as a replacement for petroleum which is both expensive and very hard on the environment in terms of emissions.
Ethanol is usually produced from corn. It is quite readily available in most places and in some places it is actually mandated. It lowers emissions efficiently by increasing oxygen levels. Ethanol is used by some petrol companies now as part of their regular fuel.
For several years now ethanol has been used in addition to regular fuel. It makes a large difference when compared to using petrol without ethanol. However, ethanol is not as widely used as it needs to be in order to make a greater difference.
With the use of biomass, any plant fibre can be converted into ethanol. This makes it a completely natural alternative whereas petrol is not. Natural energy resources are ultimately better for both the earth and humanity.
Ethanol and bioalcohol burn much cleaner than regular fuel. This greatly reduces the numbers in terms of harmful emissions that are released into the environment. Fewer emissions are just one of the main things that modern science and technology is striving for. It is an important part of making a real difference in the long run.
Bioalcohol and ethanol are renewable resources. Due to the sun’s conversion of plants into energy, there is nothing chemical about it at all. The best fuel alternatives are easily the ones that come without a price. Of course, one setback is that there simply are not enough filling stations with bioalcohol or pure ethanol fuel options. Considering how many vehicles are on the road worldwide, that is something that really needs to be changed.
There are many things that create ethanol or bioalcohol. It does not only come from corn. Potatoes, barley and sugar cane are all fantastic and natural products that create ethanol, with a little help from the sun. There is no reason not to be investigating this option further.
For those that truly want to use ethanol fuel, many mainstream gas stations are offering ethanol blended fuel. Of course, petrol is still involved in this type of fuel. However, ethanol blended gas is still better than strictly petrol only. It certainly is a positive step in the right direction. Making the switch to a petroleum alternative is a personal choice as well as a global one. It’s understandably complicated but it is something we all have to learn to work together at.

- Ethanol Biomass – What You Need To Understand At This Time
Ethanol fuel biomass may be defined as vegetable substances or plants currently in use to generate gasoline or sustaining energy. More particularly this is a biological origin that is extracted from the living matter. Ethanol has derived its alternative energy coming from plants like corn, switchgrasses, hemp, willow and sugar cane along with additional vegetation which provides or hold sugar. A large number of plant life either is made up of sugar or simply has a number of component inside it that can be converted to sugar. This valuable sugar is required for ethanol production which is done through fermentation, distillation coupled with dehydration. Non-renewable fuels do not fall into this category. They aren’t polar solvents as is ethanol, as a substitute they are hydrocarbons.
Extracting cellulose from specific plants like corn is a challenging practice. Cellulose consists of a component of strands which contain sugars and also all these sugars must be extracted so that they can make the carbs needed to create ethanol. The method employed is a mix of heat with pressure and particular basic acidic ailments. A chemical substance must be used in order to break up one of several chains of glucose and connects on the freely end of the chain and performs its way through the chain breaking down units of sugar (glucose). The closing step is to break up the sequence straight into two molecules and ferment this straight into ethanol. That is a costly strategy to get to ethanol. Researchers have offered a way of biologically engineering a bacteria that would certainly break down the actual components needed to make ethanol biomass.
Ethanol biomass is a controversial issue specially in the process of biologically designed microorganisms as well as the concern of it escaping to the atmosphere. On the other hand, there was significant hot debate around the usage of ethanol in the us. Controversy isn’t always a deterrent to continue no matter whether it’s industrially or even scientifically. We all view controversy as nothing more than thoughts and we all might need thoughts to better our own opinions, transform our system of doing anything and most of all as a means to advance forward, to improve. After all bio ethanol fuel is essential for the future of our planet.

- How Biodiesel Processors Can Can Save your Money
Muna wa Wanjiru asked:A biodiesel processor is a combination of a reaction vessel and a still for producing biodiesel from vegetable oil.
What is biodiesel?
Biodiesel can be distinguished from the straight vegetable oils (SVO) or the waste vegetable oils (WVO) which are used as fuels in some diesel vehicles. Biodiesel refers to a diesel which is equivalent to the processed fuel resulting from the biological sources such as vegetable oils which can be used in unmodified diesel engine vehicles.
Biodiesel can be prepared at home. To make biodiesel you will require the following ingredients namely any triglyceride fat or oil i.e. vegetable which is used in cooking, a relatively pure alcohol i.e. either ethanol or methanol and you will also require a strong base like sodium hydroxide (NaOH) or potassium hydroxide (KOH). A long carbon chain which is longer than that of isopropyl alcohol do not work so well. Used oil is often acquired from restaurants for processing.
There are various methods of preparing biodiesel. It is commonly prepared in the garages in small batch processors while some have adapted processors that fit in the backs of vans which makes it transportable. Home brewers face difficulty that they produce a mid-scale biodiesel which is too simple to be cheap, easy to make, safe and appropriate that the producers have sufficient quality for their requirements. There are many advices available on biodiesel forums which are dedicated to the producers and to the users of biodiesel.
How biodiesel processors can can save your money
Biodiesel is an alternative fuel that is prepared from renewable resources. It burns quickly and is safe to be used in any diesel engine vehicle. Biodiesels have many advantages and it is considered to be the fuel of the future. One of the biggest advantages of biodiesel is that it can be prepared at your own home.
