Evaluate the Advantages and Disadvantages of Electric Cars Before You Purchase

Posted by on Monday, 9 May, 2011

Thinking about purchasing a new electric car? Even more people are investigating the right way to convert a car to electric.

There are some definite positive factors about driving an electric car. And, in case you research it long enough you will also find some disadvantages. Before you decide one way or another, take into account a few of these issues.

Electric Car Advantages

1) Reduced emissions. Electric cars are “green” and will not pollute the environment. Gas powered vehicles use just about 15% of their fuel to move the car; the rest of the fuel creates heat and polluting gases. An electric car uses nearly 80% of it’s energy to move the car.

Electric cars can be powered by renewable energy such as solar or wind power. Most electric vehicles are recharged by means of power from electric utilities. Power plants typically have well regulated emissions and can be found well away from populated areas.

2) More Affordable Fuel Costs. Compare the cost to drive 100 miles. It may take a couple dollars worth of electricity. Most gas powered cars would require $15 or more for sufficient gas to drive 100 miles. And, while gas prices fluctuate wildly according to international political conditions, electricity prices are fairly steady and normally controlled by state public service commissions.

3) Less Complex Technology. A typical electric motor might have five moving parts. A typical gas powered engine has hundreds of moving parts. Gasoline engines require systems to regulate fuel and air flow to the engine and control exhaust gases. Electric vehicles require a controller to manage power flow to and from the batteries.

4) Reduced Cost of Maintenance. Because the gas powered car has more moving parts, it requires more wide-ranging, thus more expensive, maintenance. After 7 years or so an electric car would require replacement batteries which are costly. Until then, maintenance entails rotating the tires and filling up the windshield washer fluid.

Electric Car Disadvantages

1) Higher Initial Price. At present electric cars are more costly, mainly because of the lithium-ion batteries used in most vehicles. Lithium-ion batteries are used instead of typical lead-acid batteries for their greater storage capacity which provides an increased driving range.

2) Range Restrictions. Our current battery technology can only store enough energy for a vehicle to go 50 to 100 miles before recharging. The range mostly is dependent on the type of battery, car weight, and transmission (manual or automatic). The vast majority of electric vehicles are used for neighborhood driving and are recharged at home. An auxiliary gas powered generator can be used to charge the batteries.

3) Recharging Infrastructure. There are a growing number of recharging stations around, mostly in urban areas. They are by no means as ubiquitous as gas stations. Without an auxiliary generator your driving range often restricts you to neighborhood errands.

4) Battery Replacement Expenses. The cost of batteries may range from several thousand dollars to ten thousand dollars or more based on the type and number of batteries required.

5) Time to Recharge the Batteries. You can fill up a gas powered car in only a couple of minutes. An electric vehicle may take hours to recharge. Charging duration is dependent upon several factors including the kind of batteries, the controller used as well as the current and voltage available. Changing can take as little as 20 minutes or could require 8 hours or more.

Is an electric vehicle in your future? You have now got an idea regarding the major issues involved in making the best decision.


Methods To Keep Your Self Made PC From Over Heating

Posted by on Monday, 9 May, 2011

If you’re planning on creating your own computer, I highly recommend you do so. Building your own computer is great because you get to custom select everything you want and you may even end up paying less. On top of this, your new PC will look a lot more stylish. When you look at it, you’ll be proud of it. With all of the great computer towers for sale, it won’t be hard to choose something that looks just the way you want it to.

I should mention however that if your computer isn’t built just right, it will overheat regularly. People that create their own computers make them super strong. This is because a person can make a great computer with the same amount of money they would have spent on something that doesn’t have much power at all.

Sadly, a lot of new computer creators don’t realize that their new and powerful pcs will need cool computer cases to house them. When you create your computer in a cool computer case, it really helps to keep it a good temperature.

The way cool computer cases work is through a system of good air flow. They do this by creating enough space that you’ll be able to move air in and around the inner components of the computer. This is especially important when you build up the areas around the processor.

Cool computer cases will also have great fans inside of them. Many times they will have multiple fans in different areas to make sure everything stays cool all of the time.

While investing in cool computer cases is a great way to keep your computer running smoothly, you should also note that there are other factors that come into play. One factor is how clean the computer is. It is very important to keep your computer clear of dust and debris. Dirt will only create a layer of heat insulation that will lead to an increase in internal heat.

Another thing you can do is to keep things away from the computer that block air vents. Your fan will not be very useful if it doesn’t have a place to push the hot air out of.

The Basic Functions of a Radiator

Posted by on Monday, 18 October, 2010

Radiators essentially function by circulating incoming hot liquids (or in the case of vehicles, coolants) and releasing their heat through aluminum fins so that the liquid/coolant is at the correct temperature. In automobiles, coolant reaches the correct temperature and is then suitable for recycling through the engine block and back into the radiator. If coolant gets too hot and expands too much, it causes the radiator to boil over.

Radiators are structured with aluminum tubes that connect to the fins. This structure drains the heat of the coolant into open air flow. There are several smaller components attached to radiators that may fail and cause problems with normal radiator function. Radiators are fairly simple to diagnose as symptoms are very noticeable in most instances. For example, if your car tends to overheat when you are idling, the probable suspect is head gasket failure. This problem causes air to flow into the water jacket of the engine throwing off the circulation of coolant through the radiator. This specific issue is to blame whenever air bubbles are fond in the coolant or foam is inside the expansion reservoir.

The seals on the radiator cap can allow excess air into the system when they become damaged. This negatively affects the very sensitive internal pressure systems of the radiator. The radiator is not able to cool the engine block down effectively when the pressure levels aren’t normal. Once the control over the flow of air is lost, corrosion as a result of pollutants in the air and uncontrolled coolant expansion often induce boiling over in the radiator.

Automotive radiators have fans that are designed to keep the engine block cool when your car isn’t moving. When you are driving through the desert in the summer and you get caught behind an accident, forcing you to come to a standstill in traffic, this fan becomes an important ally. One the common problems that affect the radiator fan is corroded wiring that links the fan and the radiator.

Consider quality when purchasing new coolant for your radiator. The use of silicate-based coolants may significantly affect the amount of build-up you get in your radiator over time. This build-up can eventually clog your upper and lower radiator hoses causing the coolant to back up or leak. Is just as crucial to watch coolant levels. When you consistently see low coolant levels, check the head gasket and radiator cap for damage.
