In the next few years the impact of petroleum (fossil fuel) burning vehicles on the environment will only get worse. We need to reduce our dependence of imported oil, we can do this by utilizing alternative fuels that are derived from resources other than petroleum. Some of these resources are renewable and can be produced here in the United States. With all of the technology we have available today we have to start using it. We need alternative fueled vehicles more than ever with rising fuel costs, and a dwindling fuel supply, because gasoline engines omit emissions which aid in Global Warming. As the temperature continues to rise, sea levels rise, the oceans temperature rises, echo-systems will fail, agriculture will suffer, disease will spread, and natural disasters will increase such as: floods, droughts, hurricanes, wild fires will all be at record highs. To ignore the devastating effects possible from global warming would be futile. Green house gasses have to be lowered now to avoid catastrophe. It is imperative new alternative fuel sources emerge immediately to avoid the inevitable. There has been consistent research and development to help diminish our dependency on foreign oil. Some of the ideas presented are new while some are out of the past such as: steam, air, electric, robotic, hydrogen, solar, flying cars, under water cars, and computer cars. Once auto makers get on board in full stride and emerge, competition erupts between automakers, and we finally see the results of their efforts. In the near future automobiles with internal combustion engines will still dominate our roads, as auto makers continue to improve fuel efficiency in these cars everyone drives. The EPA estimates an increase in fuel efficiency of 30% over cars produced 15 years ago. The advance in technology has led automakers to build engines 63 percent more powerful than cars built 20 years ago. The fuel used to transport most of us is petroleum based, gasoline and diesel account for over 90 percent of the fuel used. Alcohols – Ethanol and Methanol A) Ethanol- an alcohol based fuel also called grain alcohol 6) Liquefied petroleum gas (LPG) (also called propane) - hydrocarbon gases under low pressure. 7) Liquids made from coal - gasoline and diesel fuel that doesn't come from petroleum. 8) Biodiesel - a lot like diesel fuel, but made from plant oil or animal fat. (Transportation Energy) E85 a blend of ethanol (85%) and gasoline (15%) used in flexible fuel vehicles. {draw:frame} A battery electric vehicle uses batteries to power an electric motor to propel the vehicle. BEVs do not produce emissions, these are a natural choice for enthusiasts. The batteries are located {draw:frame} in the rear of the vehicle and recharged from the grid. These vehicles regenerate power from coasting down a hill and from braking, called regenerative braking. The need to improve the batteries used in these vehicles to prolong trips from short trips to longer trips is under way. The diagram on the right provides some insight of the lay out of components used in this type of vehicle. Hydrogen is being explored as a fuel for passenger vehicles. It can be used in fuel cells to power these vehicles by generating power for electric motors or burned in conventional engines. {draw:frame} The innovation of this technology is environmentally friendly and helps reduce emissions from petroleum burning vehicles. A few hurdles will have to be addressed before it is widely available and in use. This energy source can be produced domestically from several different sources. No greenhouse gasses are produced while being used in fuel cells. Hydrogen provides less energy as opposed to gas or diesel, so storage becomes an issue. Being able to store enough hydrogen on...
