Discovering The Right Alternative Fuel Is Only Just Around The Corner

Saturday, September 24th, 2011

There is a really big force for people to use some type of alternate fuel instead of gasoline, right now in the United States. There can be a lot of reasons why this is going on at this time. With the concerns about the issue of global warming, people are looking for ways to slow this down and think that using alternative fuels will help. Operating a vehicle has become very expensive, and this price continues to rise at an alarming rate.

Consequently, individuals are researching ways to minimize their fuel bills. Scientists are constantly looking for ways to find alternative fuel sources that are not only good for the environment, but also that ever important checkbook of the consumer. Consumers want to have faith in new fuels, because they are sick and tired of paying such high gas prices. Yet the concern about being ripped off prevents many from trying new technologies that could actually work.

Customers are really aiding themselves, when they choose to not only heat and cool their homes, but use alternative fuels to fill up all of their vehicles. The environment is assisted as well, when the choice is made to not use gasoline, and the resulting toxins are kept out of the atmosphere. These as well as other fuels have been observed to bring heated weather to the globe, to where winter will continue to get warmer. Whatever is simply not made from crude oil is the simplest way to explain what alternative fuel is. Which implies any fuel that will power a car or truck other than gasoline.

With the launch of the 1990 Clean Air Act, expansion of alternative fuels has been pushed since these fuels can lower pollution and conserve energy. Ethanol is easily the most well-recognized alternative fuel and appears to have been used for a long time. As it originates from corn, it not only benefits buyers and the earth but also many farmers. Ethanol, which is also also known as grain alcohol, can also be produced by organic waste materials such as paper and logging debris.

Unlike the alcohol that you get if you order a drink from the bar, the ethanol used in motor fuel is denatured. The objective of that is to add a poison so people will never drink it. A significant amount of energy is required to produce ethanol defining it as questionable as to whether it is actually worth producing. Sometime soon, ethanol is likely to become more economical due to what advancing technology. Seeing that education increases and lots more people understand the damage being done to the planet, there will be a growing trend to using alternative fuels. The time is without question fast coming when we won’t be able to wait to make changes. Other energy resources will be used up.

Is Vegetable Oil Diesel A Viable Fuel Option?

Sunday, September 27th, 2009

In the late 19th century, French born Rudolph Diesel invented an engine without spark plugs, and he used vegetable oil diesel to fuel it. Fossil fuels were cheaper than vegetable oils and so petroleum became the preferred fuel for the diesel engine.

Interestingly, in 1912, Diesel was quoted as saying “The fact that fat oils from vegetable sources can be used may seem insignificant today, but such oils may perhaps become, in the course of time, of the same importance as some natural mineral oils and tar products are now.”

Vehicle enthusiasts played around with using vegetable oil to fuel a diesel engine throughout the 20th century, but serious research into it’s use was largely prompted by shortages in petroleum, from time to time, in that same period. Biodiesel often proved to be a preferrable option because it didn’t rquire modifications to the vehicle.

Both new and used oil can be utilized as a diesel fuel. Waste or used vegetable oil (WVO) comes from restaurants and food processors, after it has been used for frying food. Unused oils are called straight vegetable oil (SVO) or pure plant oil (PPO) to avoid any confusion with the blended fuel called biodiesel.

The main plant crop used is rapeseed, also known as canola, and research has been conducted using sunflower oil, which has a lower freezing temperature. Some South Pacific nations are using cocnut oil in an attempt to reduce their dependance on oil-producing countries. Coconut oil appears to work in diesel engines if the air temperature stays above 17 degrees Celsius.

Vegetable oil diesel is not without its problems. Because of its thickness or viscosity, it may cause damage to the engine, especially in colder climates. Engine conversions and kits are available to make it possible to use the fuel safely and efficiently, and blends of regular diesel and vegetable oil diesel are also used.

There has been a varied response from different governments around the world to the use of vegetable oil as diesel fuel. The issue seems to centre around the taxation of the fuel, rather than the legality of using it. Some countries have pilot schemes running to test the viability of the oil as a fuel, others have no legislation to cover it, while others seem more concerned about fuel taxes being paid than the fuel’s viability.

The availability of vegetable oil diesel remains a short-coming. There would appear to be many sources of waste vegetable oil, but straight vegetable oil has a variety of uses and so is in short supply for use as diesel fuel on a large scale. There remain a number of issues that need to be addressed before vegetable oil diesel fuel will be readily available.
