Kevin Hassett put forth an interesting view on Ethanol claiming that its promotion and use is really a political racket: " The fact is, ethanol is a scam that allows farm states to extract resources from everybody else and pretend to be virtuous while doing so. We would all be better off if Congress just wrote these states a check with no strings attached. At least then we wouldn't be wasting all that energy." (source )
Hassett claims that not only does Ethanol take more energy to produce than it generates but it also produces waste through pesticides and herbicides and is ultimately not a viable replacement for oil. Ultimately, Hassett feels that congressman see Ethanol as a "cash cow for their constituents."
As Ethanol becomes more known through recent promotional efforts from GM and with President Bush touting the need for alternative fuel sources, the debate on fuels such as Ethanol and hydrogen will certainly continue to be of interest to those interested in renewable energy and alternative fuels. |

Currently, researchers are hoping to alleviate the US’s addiction to oil by transforming sawdust and wood chips into bio-oil. This thick black liquid could very well become an environmentally friendly substitute for the majority of our current petroleum products.

In the eternal search for cheaper fuels, and a way to eliminate the use of fossil fuel from our environment, some clever researchers have come up with a way of making your own biodiesel fuel. But while it is often promoted as something you can "make at home", there are a number of things to consider, first.

Biodiesel is generally considered to be cleaner than traditional or "dino" diesel. It can be used in any diesel engine without the need to modify the engine or fuel delivery. Many diesel engines actually run better and tend to last longer when used with biodiesel. |

Hydrogen is the most perspective energy source to be used in future probably and thus economics of hydrogen fuel cells is quite an important issue today. This paper targets the above issue and considers the following aspects: opportunity cost factors, supply and demand, role of government and impact on USA taxes concerned with economics of hydrogen fuel cells.

Hydrogen fuel is used to power vehicles in much the same manner as tradition internal combustion engine powered cars. Additionally, hydrogen produces nearly three times the energy per pound; however, it has only about 1/10 the density in a liquid form. Therefore, a hydrogen fuel talk has to be much larger than a traditional gasoline tank.
In order to use hydrogen in a car, it has to be produced as it does not occur naturally in a quantity worth using. There are several methods for producing hydrogen including pulling the hydrogen out of water. The process to create hydrogen Unfortunately, this process required a good deal of energy. A recent study completed at MIT found that "Even with aggressive research, the hydrogen fuel-cell vehicle will not be better than the diesel hybrid ( a vehicle powered by a conventional engine supplemented by an electric motor) in terms of total energy use and greenhouse gas emissions by 2020."

WVO stands for Waste Vegetable Oil. It can be used in place of diesel fuel with some modifications to the vehicle. Generally, WVO needs to be heated before it can be used as a fuel. Modifications to your car usually include an additional tank for the WVO or some way to preheat the oil before it reaches the engine. Additionally, the oil must be filtered before you put it in your tank. Most WVO users feel that the best level of filtration is down to 5 microns or better.
