flexfuel is gay. hydrogen and flexfuel and hybrids should be abandoned and we should stick with gasoline direct injection and deisels. gdi is coming soon, and already is around in europe. its crazy ****

alright well here it is..
Alternate Fuel Sources to Fossil Fuels
Introduction
Global warming is a major problem with the world today. Temperatures are slowly starting to rise because of the growing amount of carbon dioxide in the atmosphere. “To reduce the greenhouse gas emissions that contribute to climate change, we must reduce our dependence on fossil fuels such as coal and natural gas†(Ein Publishing). Something needs to be done to help reduce the amount of carbon dioxide that is presently increasing. That something is researching alternative sources of energy for vehicles and looking into more efficient internal combustion engines. In this report, I will analyzing a few alternate fuels and the current use of fossil fuels, to conclude on what is the best choice of action.
“By putting energy efficiency, renewable energy, and vehicle technology solutions in place at the federal level, we can reduce our contribution to global warming while creating a stronger, healthier, and more secure nation.†(http://www.ucsusa.org/clean_vehicles/)
As the world is becoming more advanced in technology, more energy is being used to keep up with the changing demands for energy. At the current rate at which energy is being used, the world will shortly come to an end of fossil fuels. Fossil fuels are the world’s primary energy resource and are not renewable.
There are three main types of fossil fuels, coal, oil and natural gas. After food, fossil fuel is humanity's most important source of energy. Coal is used mainly to produce electricity. It provides light, motive power from electric motors and many electronic devices. Oil provides mobility for cars, planes, trains, trucks and boats. Natural gas is used primarily to produce heat for buildings, hot water, and industrial processes. All three were formed many hundreds of millions of years ago. They are called "fossil fuels" because they have been formed from the fossilized remains of prehistoric plants and animals. (Cothran)
Fossil fuels provide around 66% of the world's electrical power, and 95% of the world's total energy demands (including heating, transportation, electricity generation and other uses). Coal provides around 28% of energy, oil provides 40% and natural gases provide about 20%. A concern is that the fossil fuels are being used up at an increasing rate, and that they will soon run out. If these fossil fuels were to run out now there would not be a suitable replacement for them that is equally as efficient at producing the same amount of energy. Therefore, other options for producing energy should be explored. (Cothran)
There are different kinds of alternate fuels that are being used in automobiles today. The types of fuels that are used are: Gasoline, Diesel fuel, Biodiesel, Ethanol (E85), and Hydrogen. Most of these fuels still use some form of fossil fuel such as crude oil, natural gas, or coal. The Advanced Petroleum-Based Fuels activity focuses on improving the technology of the compression ignition engine and meeting emissions standards. The activity aims to develop new advanced fuels and lubricants that will decrease consumption of imported petroleum, maximize engine efficiency, and improve emissions performance of existing and future vehicles. (http://www.eere.energy.gov)
Findings with Conclusions
Biodiesel
Non-petroleum based fuels and lubricants are produced from sources other than crude oil. These include the traditional alternative fuels such as natural gas or ethanol. As well as, other transportation fuels such as biodiesel, which is made from natural gas or other non-petroleum sources. Currently the U.S. Department of Energy is trying to identify fuels and fuel blending components that are suitable for advanced-combustion engines. These engines have the potential to reduce dependence of imported petroleum. These fuels and fuel components will likely come from non-fossil sources such as biomass, vegetable oils, and waste animal fats. As well as from fossil sources other than light, and sweet crude oil (natural gas, heavy crude, tar (oil) sands, oil shale, and coal). (http://www.eere.energy.gov)
In many ways, biodiesel is the perfect fuel for buses and trucks. It produces fewer polluting emissions, supplies of it can be renewed indefinitely, and because feedstock materials can be grown domestically. By using biodiesel, it can help bolster the United States’ economy while lessening the country’s dependence on foreign petroleum products. Biofuels, such as biodiesel and bioethanol, are made from plant materials, which are available in unlimited supply. Biodiesel fuel is a
“Liquid produced from such renewable sources as vegetable oils, animal fat, and used oil and fats. Biodiesel (mono alkyl esters) has physical properties very similar to conventional diesel, but produces lower emissions.†(http://www.clean-cities.org/pdf/afvguide.pdf)
Biodiesel is a biodegradable and nontoxic fuel that can be used in late model (after 1992) diesel engines without any modifications. Biodiesel is actually good for the diesel engines because it lubricates better than normal diesel fuel. The use of 100% biodiesel fuel reduces the fuel economy and the power of diesel engines by 10 percent, which is not that much. The use of biodiesel creates 78 percent less carbon dioxide emissions than normal diesel fuel. Carbon dioxide is one of the greenhouse gasses that contribute to global warming. The combustion of biodiesel also reduces hydrocarbon emissions by 56 percent. In addition, biodiesel emissions have roughly 45-90 percent lower toxic emissions compared to diesel. (http://www.energy.ca.gov/afvs/vehicle_fact_sheets)
In addition, biodiesel is produced from renewable recourses, such as soybeans and used restaurant grease. No petroleum is contained in biodiesel, but it can be mixed with petroleum to create a biodiesel blend. Common uses of a biodiesel blend are B20 (20 percent biodiesel by volume mixed with 80 percent petroleum diesel by volume), B2, and B5. Many fleet managers have determined that biodiesel is their most cost efficient way to comply with state and federal regulations. (http://www.energy.ca.gov/afvs/vehicle_fact_sheets)
A chemical process called transesterification produces Biodiesel fuel. Peanuts, cottonseed, sunflower seeds, rapeseed and canola are all potential oil sources for biodiesel. The fuel is then mixed with an alcohol (usually methanol) and a catalyst (usually sodium). The oil’s triglycerides react with each other to form esters and glycerol. These are then separated from each other and purified. Neat Biodiesel is the name of the chemical produced from the process. When soybean oil reacts with methanol or Methyl soyate, Soy Diesel is made. (http://www.clean-cities.org/pdf/afvguide.pdf)
“Use of biodiesel does not require major engine modifications. That means operators keep their fleets, their spare parts inventories, their refueling stations, and their skilled mechanics. The only thing that changes is air quality.†(http://www.energy.ca.gov/afvs/vehicle_fact_sheets)
Granted, replacing conventional diesel with B100 reduces most tailpipe emission pollutants. It also increases emissions of nitrogen oxides. Using B100 in diesel engines, results in the large reduction of hydrocarbons (HC) in exhaust emissions. There is a 10% increase in nitrogen oxide (NOx) emissions. This creates a small overall increase of smog forming pollutants. These pollutants are responsible for the urban smog that reduces lung function, increases incidents of asthma and can aggravate chronic lung disease. Engine modifications, fuel additives, or exhaust after-treatment devices can reduce the NOx in exhaust emissions. “Although the tailpipe HC emissions are reduced, in a full lifecycle assessment, smog forming HC emissions were 35% higher than conventional diesel. The emissions are attributed to the farm
