Alternative energy development

Japan is a densely populated country, and that makes the Japanese market more difficult compared with other markets. If we utilize the possibilities of near-shore installations or even offshore installations in the future, that will give us the possibility of continued use of wind energy. If we go offshore, it’s more expensive because the construction of foundations is expensive. But often the wind is stronger offshore, and that can offset the higher costs. We’re getting more and more competitive with our equipment. The price—if you measure it per kilowatt-hour produced—is going lower, due to the fact that turbines are getting more efficient. So we’re creating increased interest in wind energy. If you compare it to other renewable energy sources, wind is by far the most competitive today. If we’re able to utilize sites close to the sea or at sea with good wind machines, then the price per kilowatt-hour is competitive against other sources of energy, go the words of Svend Sigaard, who happens to be president and CEO of the world’s largest wind turbine maker, Vestas wind systems out of Denmark. Vestas is heavily involved in investments of capital into helping Japan expand its wind turbine power generating capacity. It is seeking to get offshore installations put into place in a nation that it says is ready for the fruits of investment into alternative energy research and development.

The Japanese know that they cannot become subservient to the energy supply dictates of foreign nations—World War II taught them that, as the US decimated their oil supply lines and crippled their military machine. They need to produce energy of their own, and they being an isolated island nation with few natural resources that are conducive to energy production as it is defined now are very open to foreign investment and foreign development as well as the prospect of technological innovation that can make them independent. Allowing corporations such as Vestas to get the nation running on more wind-produced energy is a step in the right direction for the Japanese people.

The production of energy through what is known as microhydoelectric power plants has also been catching on in Japan. Japan has a myriad rivers and mountain streams, and these are ideally suited places for the putting up of microhydroelectric power plants, which are defined by the New Energy and Industrial Technology Development Organization as power plants run by water which have a maximum output of 100 kilowatts or less. By comparison, “minihydroelectric” power plants can put out up to 1000 kilowatts of electrical energy.

In Japan, the small-scaled mini- and micro-hydroelectric power plants have been regarded for a considerable time as being suitable for creating electricity in mountainous regions, but they have through refinement come to be regarded as excellent for Japanese cities as well. Kawasaki City Waterworks, Japan Natural Energy Company, and Tokyo Electric Power Company have all been involved in the development of small-scale hydroelectric power plants within Japanese cities.

History of Magnets and Their Uses

Magnets have been in use at least as far back as the 4th Century BC and likely even earlier. A Chinese tome from that era titled “Book of the Devil Valley Master” details the magnetic properties found in certain types of rock. It wasn’t much later that Chinese sailors were taking advantage of magnets by developing compasses.

Ancient Uses for Magnets

As knowledge of magnets and their properties spread around the world, some of the applications proved quite unusual. Magnets were at one point believed to restore youthful properties to skin, so much so that Cleopatra is rumored to have slept on a bed of magnetized rock. In the middle ages, various practices arose centered around magnets; some were merely superstitious and some have been found to have merit to this day.

The Chinese continued to find practical applications for magnets, including within the realm of medicine. In ancient China, heated magnets were often placed along the spine in order to align the spirit, and this belief is still practiced by some to this day. There is even currently work being done examining the curative effect that magnets and magnetic pulses can have on brain function, pain reception, blood properties, and nerve damage.

Magnets in Today’s World

The use of magnets in modern medicine continues as magnets are sometimes used in reflexology and even play a large part in modern medical technology such as the magnetoencephalography devices used to monitor brain activity.

Today, magnets are commonly used in thousands of mechanized applications. Electric motors and generators are entirely based around magnets. In such devices, magnets surrounded by electrical coils are moved by the current being passed through the coils, generating energy. Variations on this electro-magnet technology can be found in dozens of common modern devices and appliances, including cell phones, doorbells, computers, video game systems, and others.

And it’s not just the tiny magnets. Massive magnets play an integral part in construction and industrial applications. Large truck-mounted magnets are commonly used to clear construction sites of debris. Giant crane-mounted magnets are responsible for heavy lifting at construction and shipping sites. And large industrial magnets are installed in factory conveyor belt systems to separate materials.

Ironically, the “ancient” technology of magnets is responsible for one of the most futuristic of modern conveyances-the magnet train. As popularized in Japan, the magnet train relies on a field created between two magnets’ north poles (one on the train itself and one along the tracks) to lift the train, causing it to “hover” on a cushion of air. This in turn allows the train to travel safely at incredibly high speeds while providing an uncannily smooth ride. This technology, known as MAGLEV (magnetic levitation) is now making its way to America.

In fact, there are various plans in the works to build a MAGLEV train connecting large US metropolitan areas. This MAGLEV train will reach speeds up to 300 miles per hour, delivering passengers in a fraction of time compared to the same trip by car. As concern grows over energy efficiency and environmental responsibility in transportation, MAGLEV trains truly look poised to be the transportation of the future.

And that’s not to mention the fun side of magnets. Refrigerator magnets have a long tradition as an entertaining and colorful method for posting up everything from important reminders to children’s artwork. And magnets also have a long history in toys; they can be found in everything from magnetic construction sets to “Magna-Doodle” art devices to wall-crawling Spider-Man action figures.

Magnets have even made their way into the arts. “Magnetic poetry” kits are a popular way to compose random poems by arranging magnetized words against a metal surface. Some professional artists, such as Sachiko Kodoma, have even taken to incorporating magnets into their gallery exhibits. The popular X-Men series of movies and comic books even feature a character, Magneto, who wields power over gravitational forces.

So magnets are truly a unique commodity. They are an ancient discovery that is still utilized in applications as diverse as brain wave analysis, construction, high-speed mass transit, navigation, decoration, and even poetry composition. You can’t say that for too many other rocks.

The Discovery, Creation and Uses of Electromagnets

Most people are not aware of the many applications electromagnets have in our modern day life. Though we may be awed to see a car being lifted, we may not realize there are much smaller applications that make our life easier and more productive, all thanks to a few ingenious engineers and scientist who made this great discovery just over two centuries ago.

How the Electro Magnet was invented

In 1820 a Danish physicist named Hans Christian Oerstead discovered there was a relationship between magnetism and electricity, concluding that electricity had the ability to create a magnetic field. Using this theory, three years later British Scientist William Sturgeon created the first electromagnet out of a simple horseshoe shaped core with copper wire wound around. This crude device became magnetized when current was run through it and demagnetized when the electricity was switched off. The only drawback was that the magnet was not particularly strong as the copper wire used to create the electromagnet was not insulated and therefore could not be very tightly wound around the core without short circuiting.

Four years later an American scientist named Joseph Henry found a way to overcome this problem by insulating the copper wires with silk thread, enabling the wires to be wound closer together. This simple advancement created a much stronger magnetic force capable of lifting over 2000 pounds when the electric current was switched on.

Making an Electromagnet

The principle of an electromagnet remains fairly simple -a core with magnetic properties such as iron with a conducting wire wound around it. At this stage the atoms within the iron are aligned in different directions, canceling the magnetic effects. However, when an electric source is connected to the wire and switched on the wire develops a magnetic field around the core, aligning the atoms in the core and amplifying the magnetic field.

At its essence, a magnet is created using electricity combined with a conducting wire and core. The minute the electric current is switched off the magnetic field disappears and the components return to a neutral state. The ability to turn an electromagnet on and off is a great benefit and one of the reasons they have so many industrial applications.

Modern Day uses for Electromagnets

The engineering, mining, and manufacturing industries use electromagnets for many applications, most commonly to hoist containers and freight. At the more individual level, speakers in your stereo, television, and even doorbell use electromagnets. Perhaps the most impressive applications can be seen in Germany and Japan with the maglev trains -high speed trains that travel up to 350 miles per hour, courtesy of electromagnets. Amazingly these trains actually levitate above the tracks because of an electromagnetic field. And, because there are no wheels and therefore no friction the trains run more efficiently and at far greater speeds than normal trains.

Advanced applications of Electromagnets

As the field has become more specialized, different types of electromagnets have been developed for advanced applications. Used in a wide variety of industrial applications, common flat faced electromagnets are used to hoist objects that have a similar smooth flat surface. Another common type is a polar electromagnet, characterized by two widely spaced poles that form a magnetic field, allowing objects with uneven surfaces to be lifted. Scientific applications use electromagnets in research labs for micro engineering and precision handling of materials and delicate processes. Additionally, different core materials and configurations enable engineers to vary the strength of the electromagnets, which allows for further specialized applications.

Electromagnetism is a fascinating property that modern engineering will continue to find more uses for. As additional applications develop, Oerstead, Sturgeon, and Henry can be thanked for the core principle that after more than two hundred years still remains the same. What would life be like without that stereo in your car?

Making The Cut

It is believed that scissors were invented in ancient Egypt about 1500. Early scissors appeared in the Middle East some 3,000 to 4,000 years ago. The scissors worked with a spring that comprised two bronze blades connected at the handles by a thin, curved strip of bronze. This strip served to bring the blades together when squeezed and to pull them apart when released. Cross-bladed scissors were invented by the Romans around AD 100. Pivoted scissors of bronze or iron, in which the blades were connected at a point between the tips and the handles, were used in ancient Rome, China, Japan, and Korea, but spring scissors continued to be used in Europe until the sixteenth century and the idea is still used in almost all modern scissors.

Today there are many different kinds of scissors, used to create a variety of styles and cuts. From thinning and styling shears, to tempered and left-handed shears; each pair of scissors is designed to perform a specific task. Some are used to create subtle effects while others are used for more basic haircuts. While some stylists use razors or clippers to achieve more extreme results, barber shears are the industry standard. Stylists are also concerned with the production quality and the materials used as well as the tension system the shears utilize.

The quality of the cut depends on the quality of the scissors, the skill of the stylist and the techniques being employed. A particularly creative cut may require several different types of scissors, but even the most basic hair cut demands something that provides an accurate, clean cut. Inferior quality scissors or scissors with dull blades can greatly impact the haircut and may even cause damage to the hair.

There are several types of scissors available on the market today. Beveled blades feature one serrated edge and one straight edge and are ideal for layer cuts, tapered cuts and the “scissor over the comb” method. Convex blades are razor sharp and give a clean, flawless cut making them ideal for slide cutting. These are suitable for stylists who cut with their thumb and middle finger.

Scissors types include opposing grips that feature handles of the same length; symmetrical to the center screw. Offset grips feature a short thumb handle and a longer finger handle, which allow for more natural, fluid movement and are suitable for individuals who cut with the thumb and ring finger. Crane grips feature a long finger handle and an angled thumb. This ensures less strain on the wrist and shoulder and allows a freer, open cut. Other varieties include varying types of thumb grips. Some will feature a removable and reversible finger resting piece that can be attached to either the left or right grip allowing for greater versatility for the wearer.

Cutaway thumb scissors do not feature the reversible finger resting piece, but they are able to provide exceptional comfort for the wearer. Anatomic thumb scissors allow for greater radial movement due to their curved design and they provide more freedom of movement for the stylist. Swivel thumb scissors are a newer advancement in the industry. They reduce hand and wrist strain and feature an open hand grip design, which reduces thumb “travel” and creates a more comfortable experience for the stylist.

The other primary consideration that a stylist must make is with the length of the blades of the scissors. The correct blade length is dependant on the comfort and preferred styling methods of the hairstylist. Short blades are useful for detailed touchups, such as cutting around the ears or very close to the skin. This type of blade is recommended for all stylists particularly for more intricate cutting. The blade should be no longer than 5.5 inches. Long blades are ideal for cutting thick hair, slide cutting, scissor over comb methods, and bobs.

Although comfort is of primary importance, a professional stylist will have spent much time researching the different scissors available and utilize the one most appropriate to their cutting styles and the techniques that they practice.

The History Of Wool Cloth

Sometime back in the eons of prehistory, a hunter killed a sheep and brought it home to make a mean mutton stew. His little family liked it so much that he decided he’d try to catch a few of those wooly critters and keep them around, so there would always be an ample supply of meat. His days of hunting pretty much over, he settled into a nice comfortable life as a shepherd. His wife soon discovered that sheep’s milk was pretty tasty, too, and began to make cheese. Then, some time later, her man needed a new cloak to protect him from the cold and rain as he sat and watched his sheep. Being an enterprising woman, she decided t give the wooly hide of last night’s stew-giver a try. And what she discovered was that the wool not only kept her man warm on those cold mornings, but it also kept him cool in the heat of the day. His new wool cloak also kept him drier than any other she’d made, as the wool seemed to whisk the moisture away. Aha! She thought, “This is fine stuff!” She began to pluck the wool from the sheep while they were still above ground and out of her stew pot. She twisted the tough fibers into long threads, which she then wove into cloth and dispensed with the idea of the hide, dead sheep and mutton stew to get a new cloak altogether. And the wool cloth industry was born!

Now, it wasn’t really as simple as all that. It took thousands of years for all the “technology” of primitive wool cloth to be developed. Sheep were bred for the thickness of their wool, finally producing breeds with predictably useable, valuable fleeces. Shears weren’t invented until sometime in the Iron Age, so generations of sheep herders wives did actually have to pluck the wool from the sheep. By 1500 BC, though, wool cloth was the staple of European fashion, being worn by high and low-born alike, as the sheep were plentiful and the fabric easy enough to make and care for.

The Romans somewhat perfected wool cloth, as they perfected so many other existing technologies, specifically the breeding selection needed to produce Tarentum wool, the finest quality wool in the known world. Roman soldiers marched off to conquest wearing wool cloaks, carrying wool blankets with woolen socks, underclothes and other garments in the packs or on their bodies. Many of the ancient people they conquered (or tried to anyway) also wore wool. The Celts dyed their wool and wove their cloth into the forerunners of the tartans beloved by their Scottish and Irish descendants today.

The spinning wheel arrived sometimes between 500 and 1000 AD, doing away with the time-consuming hand spindle, and allowing for much finer even yarn to be produced.

Medieval Europe saw the expansion of the wool trade, with many countries’ economies carried on the backs of sheep, such as the Medici’s of Florence and the entire economy of England. The mechanization through water mills of one of the most time-consuming tasks in wool making – fulling or felting – also occurred sometime in the Middle Ages. England’s raw wool was the finest to be had, and until the Black Death, kings and their kingdoms flourished on the taxes earned from its export. Eventually, England developed its own wool textile industry, and exporting of English wool was even made illegal for a time. Weavers from Flanders and France arrived to add their expertise and English wool cloth began to be exported in greater quantities than the raw fleeces. Tweeds and worsteds were invented at this time. After the Restoration in 1666, English wool cloth was considered so fine, it began to compete with silk on international markets. One of the complaints among the American colonies against the Crown was that they were not allowed to trade their wool with anyone else. In 1797, 13 Merino sheep were exported to Australia, and that country’s wool industry was born.

The Industrial Revolution brought about the end of many traditional wool cloth practices, and introduced many new ones. Mills could be run by water, and the mechanized factories could turn out cloth faster and more efficiently. The mechanized looms could produce even more intricate patterns than the traditional hand looms, and with wool’s quality to take dyes quicker, better and “truer” than other fabrics added to the expansion of available patterns and styles. The spinning jenny could allow one spinner to operate as many as 120 spindles at one time, greatly increasing the amount of yarn produced. Powered carding machines and other mechanized tools soon replaced every portion of the labor-intensive hand preparations, and many of those skills were nearly lost.

Wool cloth continues to develop, both in usage and in manufacturing processes. The astronauts wore woolen suits to combat the freezing temperatures of space. A new type of woolen suit has been developed in Japan that allows the owner to shower it down in his bath at home, hang it to dry for a few hours, and then wear it again without need for dry cleaning or ironing. Sheep selection and breeding are also continuing their development, providing the future of wool fabric with new, endless possibilities.
