We are not talking about gasoline, diesel fuel, or kerosene right now. An alternative fuel is defined as the choice of any fuel other than the traditional selections; gasoline and diesel.

What are the choices?

1.    Ethanol. Ethanol is a high-octane, low-emission fuel that has been used in racing for a long time. It is now made from renewable plant materials and can be used in normal vehicles. The bad thing about Ethanol is that it gets lower fuel economy ratings as opposed to gasoline.

2.    Methanol. Methanol has a high octane rating and a low emission of pollutants. These characteristics make it a great fuel to use in engines in cars. Since the 1960s, the cars in the Indianapolis 500, which is a big race that is held annually, were powered with methanol.

3.    Natural gas. Natural gas is a by-product of oil drilling and also coal mining. You can also harvest natural gas from natural gas fields.

4.    Propane is another type of alternative fuel. Another name for this kind of gas is liquefied petroleum gas. Propane is the gas that is made when natural gas and crude oil is refined.

5.    There are also blends of fuels. This is how we get fuels known as E-85 where it is a mix of 85% Ethanol and 15% gasoline. These are defined as mixtures between traditional and alternative fuels. Another blend is B20.

6.    Hydrogen is one of the more popular alternative fuels. Hydrogen is made commercially by refining it from petroleum. You can also make hydrogen by passing electricity through water. This process is known as electrolysis.

7.    Electricity is another alternative fuel. We consider electricity as an alternative fuel choice because it has been used to power the motors in electric vehicles. Electric vehicles are becoming more and more popular nowadays and they will be mass-produced in late 2009. Most people think this is the answer to our economy problem but what most people don’t realize is how expensive these electric vehicles are.

8.    Biodiesel is another popular alternative fuel source. This is an additive or even a replacement for diesel fuel. biodiesel is made from animal fat and sometimes vegetable oil.

9.    Biomass. Biomass is derived from materials that are biological, predominantly vegetation, these include biofuels such as ethanol and biodiesel.

10.P-series. This is a colorless, clear liquid fuel which have between a 89 and 93 octane rating. P-series fuels are designed to be used in flex-fuel vehicles. This will become more and more popular as we see more flex-fuel vehicles.

This is just one list of the alternative fuels. There are many more out there we just need to discover them. Once a good alternative fuel is discovered that we can mass-produce very cheap which gets better gas mileage than our traditional fuel, the economy should start booming again.

Biodiesel becomes more and more popular every year. It’s popularity probably derives from the fact that biodiesel is so cheap and relatively easy to be made. You can make it in your own backyard or kitchen. It is far better than the original petro-diesel, it’s cleaner and better for the environment and your health. Let’s talk about the three options you have when running a diesel engine on biofuel.

All three options can be used with vegetable oils, animal fat or both (it doesn’t matter if you use fresh or used oils):

- You can use the oil as it is

- You can mix the oil with another chemical supplement like kerosene, or gasoline or petroleum etc.

- You can convert the oil to biodiesel

Using the oil as it is can be clean and effective. Not to mention cheap also. But you have to make modifications to the diesel engine so that it is optimized for vegetable oil. You can find pre-modified diesel engines where you can use petro diesel, biodiesel and pure vegetable oil in any combination. There are engines with separate fuel tanks and a switch, you fill one tank with vegetable oil and the other tank with original petroleum diesel. Then you just turn on the engine using the tank with the original petroleum diesel and after a while you switch to the tank with the vegetable oil.

Mixing the oil with other supplements is your second option. Because vegetable oil is thick you mix it with a different type of fuel to make it thinner so that it flows easily into the combustion chamber of your diesel engine. Remember that using petroleum or kerosene to mix the vegetable oil, is not a clean option though. You can make various mixes (for example 20% vegetable oil and 80% of another diesel fuel). Some claim that if you use such a mix you have to preheat the engine, others just start the engine and go without preheating.

Your final option (and by far the best, in my opinion) is to convert the vegetable oil into biodiesel. Because biodiesel works in any diesel engine without the need to make any conversion or modifications to the fuel system or the engine itself. Just fill and go. Biodiesel is a much safer, clean, ready to use fuel that’s well tested. This option unlike the other two is backed by thousands of short-term and long-term research and tests by scientists around the world.
