Solar Powered Cars

Wednesday, January 3rd, 2007

In the 1990’s, emissions laws were being enforced throughout the United States. Many colleges and universities began looking at the possibility of solar powered cars. The finding were that the solar collectors for the cars to run were too large to be put into the vehicles. Development continues on the solar collections to make it possible. For those skeptical, don’t be surprised if it doesn’t all come together in the near future. There are many organizations throughout the world working on doing just that.

Students are aware that using fossil fuels for cars has a negative impact on the environment. Students investigate the amount of pollution a car creates. Students have the opportunity to work together with their research and other students to investigate how to use solar energy for cars. They research the challenges involved and work to find solutions. (more…)

Portable Solar Power

Wednesday, January 3rd, 2007

Solar energy is a clean and efficient for of energy. The demand for it is greater than the supply. The cost of supplying electricity to remote locations is expensive and time consuming. Solar power is an excellent alternative. Portable solar power has been referred to as packaging sunlight. The concept is using an adapter to allow you to use solar power that has been accumulated during times when you do not have enough solar energy. They are mainly used at night.

Battery chargers with solar power are very popular. They simply plug into your cigarette lighter and charge your car in minutes. On a larger scale you can purchase portable generators that will allow you to use energy produced by sunlight when sunlight is not available. These power sources are used by corporations, small businesses, and individuals. They are used to supply power to entire networks or simply to operate your DVD player. The type and size of generator you want to purchase will depend on your individual needs. Within the next three years, it is believed solar panels will be made that can supply power to cell phones as well. However, the cost of such phones is anticipated to be high because it is expensive to design that type of solar panel. (more…)

Podcasting

Wednesday, January 3rd, 2007

Podcasting is audio content, such as a MP3 Player, that is sent over a RSS feed. It is a file that is downloadable for use over the internet. The name is misleading though, as it infers that you must have an iPod to use it. You only need a computer or laptop to access podcasts. This process is fairly new, becoming popular in 2000. Technology allowed it to be used by multiple components as early as 2001. However, it wasn’t until 2003 that podcasting became very popular on everyday websites.

The process of podcasting is very simple. Computer files in multimedia format are downloaded to a server. The customer can then download them in a matter of seconds from the server onto their own system. It allows the user to see the audio and have sound at the same time. Downloading can be frustrating for users who don’t have the proper bandwidth to view them. This can be easier fixed by downloading software online or having a computer installer do it for you at a reasonable cost. Basically, the faster your connection, the better you will be able to view podcasts. (more…)

Solar Power

Wednesday, January 3rd, 2007

Solar power is the process of using the light from sun and turning it into an energy source. It has become a reliable alternative to regular power sources in remote areas. It has even been used in outer space. Solar power is used in homes, lighting, architectural projects, and cooking. It has become even more popular as the cost of fossil fuel continues to rise. Solar panels are designed to collect the power from the sun.

Once solar energy is collected by the solar panels it has to be converted into energy. This can be done by a process called solar thermal application. It involves using the energy from the sun to directly heat air or liquids. The process of photoelectric application involves the use of photovoltaic cells to change the energy into electricity.

American Flag

Tuesday, January 2nd, 2007

On January 1, 1776, the Continental Army came under the control of George Washington. In May of that year, Betsy Ross sewed the first American Flag, consisting of 13 stripes, alternating in colors of red and white. George Washington had it hoisted at Prospect Hill. She was a struggling seamstress who knew George and Martha Washington from Church. George Washington showed her the layout, which included stars with 6 points. She cut out a star with 5 points, and George Washington is said to have liked it and went with the design.

The first flag act was passed in 1977. Congress declared that the official flag of the United States would have 13 stripes, alternating red and white. It would also have 13 white stars on a blue background to represent each of the states in the Union. The stars each had 5 points, and were designed in a circle, representing the unity of the states. This flag act was updated several times through 1960. Congress added to it each time new states joined the Union. (more…)

Flag Displays

Tuesday, January 2nd, 2007

While types and colors of flags vary by country and organization, there are some universal rules for properly displaying flags. It is customary to only display the flag from sunrise to sundown. When flying a flag at half-mast, it should first be taken all the way to the top, and then slowly lowered to half-mast. This is usually done to represent a time of mourning, a death, war, or other similar issue. Flags in the United States were at half-mast after the terrorist attacks of 09/11.

The flag of the country should be dominate where a display has more than one flag. For example, a display with a state flag and the United States flag should have the United States flag flown higher than the state flag. The country flag should always be hoisted first and lowered last out of respect. When flags are at half-mast, the country flag should be flown at half, with the state flag slightly lower. (more…)

Flag Poles

Tuesday, January 2nd, 2007

Flags have been used for various reasons for over 4,000 years. Wooden poles were hand carved to display the flag on. The poles were later made of metal. A decoration is sometimes added to the tip of a flag pole, called a finial.

Flag poles today continue to be made of wood or metal. In addition, some are made of fiberglass. The flag pole is generally erected very high so that the flag can be seen waving freely in the sky for all to see. Flag poles vary is height from 10 feet to 80 feet on average. At a height of 525 feet, the flag pole in Gijeon-dong, North Korea, is the highest in the world. On a similar note, the largest flag in the world is in Basilia, Brazil. It weighs 1,300 pounds! A flag is raised onto the flagpole by the use of a pulley. Proper flag displaying is to raise the flag at sunrise and lower it at sunset. Flag poles should be securely cemented into the ground.

State Flags

Tuesday, January 2nd, 2007

Each of the 50 states that make up the United States has their own state flag. While they are all united under the American Flag, the individual flags represent their own ideals as well as freedom and individual rights. Every state also has a song, state bird, and state flower. Each state flag has a unique design.

Alabama and Florida have very similar state flags. Both are white with a big red X across it. Florida’s also has an emblem in the middle while Alabama’s is white. Georgia, Mississippi, Hawaii, Missouri, North Carolina, Ohio, Tennessee, and Texas all have flags that are a variation of the America flag. The colors are a combination of red, white, and blue. Several of them have stripes as well. (more…)

Flags

Tuesday, January 2nd, 2007

The first known flags were those used around 3,000 B.C. in Ancient Greece and Egypt. They were called vexilloids. Today we call vexillology the study of flags. These first flags were carvings on top of metal or wooden poles. It wasn’t until 2,000 years ago that the idea to use material with a design on top of the pole was introduced. Flags are used to give a message, represent your organization, and celebrate events.

Today, a flag is described as a colored fabric that symbolizes something or that sends a signal. In medieval times, Knights carried flags to easily tell their friends from their enemies because they all looked alike in their armor. Most everyone is familiar with surrender flag, a plain white flag waived to indicate to your enemy that you give up. (more…)

Coffee Machines

Monday, January 1st, 2007

Drinking coffee is a pastime of millions of people all over the world. Coffee machines make it possible to meet the demand of all these people. Without coffee machines, it would not be possible.

The first coffee machine was invented in 1818 by Mr. Laurens. The machine was continually modified. New versions of the coffee machine continued to emerge until 1960. This is when the first paper filters for coffee machines were put into place. This simple change created an unbelievable increase in coffee machine sales. People had always wanted the product, but didn’t like the time it took to clean up and prepare with the cloth filters. (more…)
