Ethanol (CH3CH2OH; also known as ethyl alcohol, grain alcohol, and EtOH) is a clear, colorless liquid. Its molecules contain a hydroxyl group (-OH) bonded to a carbon atom.
The chemical compound in ethanol is the same whether the fuel is made from corn grain starch (as it primarily is in the United States) or sugar cane (as it primarily is in Brazil) or from cellulosic materials. Corn and sugar cane are commonly used to make ethanol today.
Ethanol can also be produced from fibrous cellulosic biomass materials, such as grass, vineyard grapes, wood, crop residues, or old newspapers. Breaking these materials down to their component sugars for subsequent fermentation to ethanol is a major focus of U.S. Department of Energy research. Whether made from starch in corn grain or cellulose in corn stalks, ethanol is a renewable, domestic biofuel.
Ethanol works well in internal combustion engines. In fact, Henry Ford and other early automakers thought ethanol would be the world's primary fuel before gasoline became so readily available. A gallon of ethanol contains one-third less energy than a gallon of gasoline.
Ethanol is a high-octane fuel. Octane helps prevent engine knocking and is extremely important in engines designed to operate at a higher compression ratio, so they generate more power. These engines tend to be found in high-performance vehicles. Because ethanol has high octane, it is sometimes blended with gasoline in small amounts to boost octane rating. This mixture, in turn, can be used in high-performance engines.
Low-level blends of ethanol, such as E10 (10% ethanol, 90% gasoline), generally have a higher octane rating than unleaded gasoline. Low-octane gasoline can be blended with 10% ethanol to attain the standard 87 octane requirement.
Ethanol is the main component in E85, a high-level blend of 85% ethanol, 15% gasoline.

Getting Auto Moving Insurance
Any auto transport company that has a license for car moving activities should have cargo and liability insurance as well. You need to have a clear idea of it, for if your car gets damaged on the road you will probably want coverage. It is not that something will happen for sure, but it is better to be safe than sorry, isn’t it? The first thing you should do is make sure that your car moving company has an insurance certificate, don’t be shy to ask them to show it to you. You are not obliged to believe anyone until you see the proof with your own eyes. If you still have any doubts don’t hesitate to contact their insurance company so as to double check the information.
Some auto movers provide very limited insurance coverage, sometimes it is even less than your car is actually worth. Inquire at their insurance company as for the exact terms and rights that you are offered. The things that you need to know are:
· Can you buy additional coverage?
· What is the limited coverage amount (if any)?
· Are there any parts of the vehicle that are not covered?
· What type of damage is included in the insurance?
The car moving company should provide you with insurance against theft and damage. It is highly recommended that you have a hard copy of their insurance policy spelling out whether their coverage is secondary or primary to your car insurance. Remember to contact your own car insurance company as well in order to find out what kind of coverage is provided by your existing policy.
If you are not sure whether your home policy insurance covers any damage or loss of your personal items, it’s better to remove them from your car. Car movers don’t usually insure any contents of the vehicle except for such items as a jack and a spare tire that are necessary.
You should also make sure that your vehicle carrier is registered with the Department of Transportation, if you want to avoid any possible troubles with getting the coverage in case of an insured accident.
If there are any disputes, it’s better to try and resolve them with your auto moving company first. They are usually determined to workout any problems. However, if you did your best but still feel that you have been treated in an unfair manner you can file complaints to the Federal Department of Transportation, BBB or Interstate Commerce Commission.

Is auto transporting for me?
Auto Transporting is not free. With every service their is a cost. Depending on how far and the type of vehicle you wish to move, it may not be worth doing. For an example if you own a 1992 Honda Civic that leaks oil, that starts 50% of the time and is a rust magnet, you should not waist your money and time transporting it. Some companies will only move vehicles that are in good running order. You will also want to consider if you want to put the extra miles on your vehicle. When your vehicle is transported on a truck, no extra miles will added to the engine. Also the cost of gas and accommodations that you will have to pay out of your pocket will be costly, especially for longer moves. If your moving across the country, choosing an auto transporter to move your vehicle is a wise decision.
As you can see it is usually a good idea to choose an auto transporter over driving your vehicle yourself. The benefits of auto transporting usually always outweigh the costs. Remember to contact various auto transport companies and do your research. It will make your auto transporting experience go much more smoothly.

ELECTRICAL POWER SYSTEMS (ELP)
In line with its privatization efforts, the SAG brought about a merger between the Saline Water Conversion Corp. (SWCC) and Saudi Electricity Co. (SEC) to carry out independent water and power project (IWPPs) in partnership with developers. Reform in the electricity sector is advancing slowly in the need to re-price services, establish quality control standards, promote private investments, and protect consumer rights.
In May 2001, the SAG approved the formation of the Gulf Interconnection Authority (GCIA), which will be responsible for connecting the national grids of the Gulf Cooperation Council (GCC) states, which include Saudi Arabia, Kuwait, Bahrain, Qatar, Oman, and the United Arab Emirates. The company will develop the scheme on a build-operate-transfer (BOT) basis. The initial phase of the grid connecting the Northern Gulf region, including Bahrain, Kuwait and Saudi Arabia, will stretch some 1,200 kilometers and is expected to come on stream in 2008.

What is an electric vehicle?
In an electric vehicle (EV), a battery or other energy storage device is used to store the electricity that powers the motor. EV batteries must be replenished by plugging in the vehicle to a power source. Some electric vehicles have onboard chargers; others plug into a charger located outside the vehicle. Both types, however, use electricity that comes from the power grid. Although electricity production may contribute to air pollution, EVs are considered zero-emission vehicles because their motors produce no exhaust or emissions.
There are currently no light-duty electric vehicles available from the major auto manufacturers. Neighborhood electric vehicles (NEVs), on the other hand, are being manufactured by a variety of companies. These small vehicles are commonly used for neighborhood commuting, light hauling, and delivery. Their use is limited to areas with 35 mph speed limits or for off-road service on college campus or at airports or resort areas.
Because they can only reach speeds of 35 mpg, NEVs are not considered light-duty vehicles and are not eligible for fleet credit under the Energy Policy Act of 1992 Standard Compliance option and Federal Fleet Requirements. However, their versatility in moving people through limited commute areas makes them useful in a variety of applications. Other useful EVs in niche applications include electric scooters and bikes.
