Many vehicles are fueled by diesel, but with the increasing demand for environmentally safer fuels many diesel users are asking for better alternatives, too. Biodiesel is the name of a clean burning alternative fuel. It’s a vegetable oil-based fuel that can run in an unmodified, or slightly modified, diesel engine. It is produced through a chemically-refined process called trans-esterification. Essentially, biodiesel is a renewable fuel made by a chemical reaction of alcohol and vegetable or animal oils, fats, or greases, that seaparates the glycerins in the oil from the methyl esters. It is methyl esters which form the biodiesel and they can be merged with regular diesel or it can be used alone. Biodiesel is biodegradable, nontoxic, and free of sulfur.

Pros Of Using Biodiesel

Contrary to popular beliefs, biodiesel is not raw vegetable oil. As an alternative fuel, biodiesel must be manufactured according to strict industry specifications in order to insure proper performance and is the only alternative fuel to have fully completed the health effects testing requirements of the 1990 Clean Air Act. Biodiesel is nearly carbon-neutral, which means it contributes almost zero emissions to global warming.

Biodiesel has fewer emissions than standard diesel, is biodegradable, and is a renewable source of energy. The exhaust emissions of sulfur and its related compounds contribute to the formation of acid rain; carbon monoxide is a widely recognized toxin; and carbon dioxide contributes to the greenhouse effect. There are also some lesser known emission compounds that cause concern, such hydrocarbons that have been linked to the formation of certain types of cancer. Particulate matter has negative health effects upon the lungs, and unburned hydrocarbons contribute to the formation of smog and ozone. These are basically eliminated when biodiesel is used instead of regular diesel. Biodiesel also lubricates the engine better than petroleum diesel, which helps reduce engine friction and wear and extends engine life.

Cons Of Using Biodiesel

Of course, as with any other fuel source, biodiesel has its downsides. Pure biodiesel gets slushy at a little under 32

The truth is oil and automobile companies are creating alternative fuel expansions to help with the escalating prices of gas and oil, and global warming. The companies are at the point where they realize it is time to do something because consumers are fed up, the environment is in danger and there are cheaper methods.

Alternative fuels are not made from crude oil, which would end the United States dependency on foreign countries. Such alternatives fuels are made from corn, wheat, vegetable oil, pretty much anything that is organic. Companies have even used old car parts to create fuel. These types of alternative fuel expansions are amazing because it is taking natural products that can be grown anywhere, or garbage that needs to be disposed of and using it in a productive, cost efficient manner.

It isn’t all about the money either. The global warming problem has received international attention as of late and many countries, citizens and people are taking a stand to help the environment. The alternative fuels burn cleaner and produce less CO2, which is a major culprit in global warming. Less garbage, less CO2 and cleaner air. Alternative fuel expansions sound like a winning combination.

Major car companies are taking the biggest leaps when it comes to alternative fuels expansion. With the price of oil, car companies have taken the biggest hit. Consumers are looking for more fuel efficient vehicles or even those that don’t require the gasoline that is available at the pump these days. Car companies are creating cars that run on electricity, ethanol, E85 and biodiesels. With the new wave of technology these car companies are creating also come the growth of jobs. Some of the alternative expansions are still in its infancy stages, but many vehicles such as E85, ethanol and biodiesel are already on the road.

Australia and Sweden have been developing alternative fuel expansions. Those countries already have E85 vehicles on the road. E85 means the fuel is 85 percent ethanol. It also becoming popular in the Midwestern part of the United States where large crops of corn are grown.

Big oil companies are taking notice and are now putting different kinds of pumps at gas stations where there is a demand. As a child, when you used to think about how electric cars would run in the future, you probably never thought it would happen in your lifetime. Well, buckle up because the future is coming. Alternative fuel expansions are changing the way people think and changing lives.

Things have been heating up all over the world with the rise in the price of crude oil and ever increasing awareness of global warming. People are wondering if the oil prices will settle down and whether this is just a taste of things to come.

There is great tension between major oil consuming countries and major oil producing countries over how to meet the ever-growing demand for oil. Considering all this, there is also a growing sense of urgency in discovering or developing alternative sources of energy that would reduce the dependence on conventional fuels. And it may surprise you to know that water is seriously being considered as one of the sources of alternative fuel.

What are alternative fuels?

Conventional fuels are fuels that have been traditionally used to provide energy in a variety of applications like powering vehicles or heating up buildings. Conventional fuels known to us are fossil fuels like petroleum, natural gas, propane and coal; and nuclear fuel.

There is a growing concern about the environmental effects that these conventional fuels are having, not to mention their economic effects. Burning of fossil fuels is known to hugely increase the emission of greenhouse gases, one of the major contributors to global warming. Production of oil is expected to go into a decline sometime, leading to demand hugely outstripping supply and leading to a major energy crisis.

These geopolitical concerns have led to many governments actively encouraging the development and use of alternative sources of fuel. The alternative fuel sources you may have already heard about are biodiesel, hydrogen, bioalcohol like ethanol and butanol, stored electricity, non-fossil natural gas and methane, vegetable oil and others. There are also sources of renewable energy like wind energy, solar energy, geothermal energy and even tidal energy. But, how about water? Can water be a serious alternative fuel for cars and other vehicles?

Water as an Alternative Fuel For Cars

With the abundance of water, especially sea water staring us in the face, it was not surprising that people have always experimented with water as an alternative fuel for cars and vehicles in general. While they may have met with some success, nothing could be developed on a sustainable scale, certainly nothing that could make an economic impact.

People however, never gave up and lately, there has been renewed talk of how water could prove to be our ideal source of alternative fuel. There are reports of some inventors who in the process of removing salt from water discovered that the water actually started to burn and generate energy. With a similar idea in mind, the HTA company developed Aquygen, a gas generated from water and which is to be used as a fuel additive. What makes this so striking is that this additive decreases greenhouse emissions and increases the overall fuel efficiency of the car, without the vehicle needing any special changes in its fuelling system! There are also reports of a Japanese company having manufactured a car that runs only on water, without emitting any CO2.

While it is obvious that all these ideas and projects are still being developed and have to be tested on a large scale, they give hope to all of us that our dependence on conventional fuels may soon be over.
