...protection on the phone line. This report offers technical background information on an alternative power protection device designed specifically for businesses that use LANs in their day-to-day operations; that device is called an uninterruptible power supply (UPS). This report compares three of the top name brands in UPSs in a point-by point comparison and offers conclusions and final recommendations for the purchase of a UPS, as well as a glossary to help define terms that are unfamiliar. TECHNICAL BACKGROUND Background on power supplies To reduce the risk of losing data to power failure, many companies protect their servers with uninterruptible power supplies. A UPS uses batteries to provide power to a connected computer in the event of a brownout or blackout. "Dirty power" is the industry term for changes, variances, and disturbances that occur during normal usage of utility provided power. A perfect sine-wave can become system-shocking "dirty power" without notice and can cause extreme damage to data and computers alike. Other equipment nearby can produce "noise on the line" that can wreak havoc with a computing environment. IBM recently reported in a study of power sources that a typical processor encounters around 128 power problems a month. These problems can be caused externally by brownouts or load switches or grid problems at the utility or caused internally by subtle disturbances from sources such as copiers, flourescent lights, faxes or even vending machines...

...Energy Storage Moves Wind to Baseload Power LONDON -- The key to further wind sector success may be the ability to provide baseload power. New solutions based on lithium batteries can deliver convincing foundations to balance wind's variability. For more than two decades, practitioners have been developing control solutions to make operating wind energy plants more efficient. One of the latest projects commissioned by a Chinese operator was dedicated to energy storage. In China, feed-in regulations stipulate that 10 percent of the power installed from wind energy plants must be available via energy storage at any time for two hours. Norbert Hennchen, managing director of Freqcon in Walsrode, Hannover, Germany says lithium batteries possess the greatest technological potential with regards to saving energy, and therefore the ability of renewable energy sources to provide baseload power. The topic of storing renewable energy is currently on trend and is being discussed and implemented on many fronts. Energy density plays a big part in this. Pumped storage plants deliver approximately 0.5 kWh/m3 from an assumed drop height of 200 metres; in contrast, hydrogen plants deliver 500-2300 kWh/m3. With the latter, however, the efficiency of the energy supply is comparably low. Lithium battery systems are right in the middle, achieving approximately 125-400 kWh/m3 - and up to 2500 kWh/m3 under laboratory conditions. When on the subject of efficiency, Hennchen's eyes light up: "Such...

...performer. 2. How is the battery industry (you can use five forces analysis to answer this question)? Has it been changing? If yes, how? Overall, the industry is very attractive. New entrants realize the potential of snagging a piece of a highly profitable industry that produced $5.2 billion in revenue and $807 million operating margin. Threat of new entrants is low, as the capital requirements and technology development needed to stay relevant in the market proves to be a daunting barrier to entry. Also, in order to realize a significant profit, economies of scale must be realized to produce a massive amount of batteries while keeping costs low. This would be harder for smaller entrants to achieve. Threat of substitute products is low, as no replacement good has been introduced that may provide the consumer with the same benefits as using a battery. This makes the industry attractive. However, if a company produced a good that could replace the need for a battery, this would detrimentally alter the battery industry, making threat of substitute products a major factor of the industry. The bargaining power of suppliers is low because there is little differentiation between the inputs of the batteries, which can be acquired from many different suppliers. This low supplier power makes the industry attractive. The bargaining power of the buyer is fairly high, as there is high buyer concentration with low switching costs, which makes the industry less attractive. The major...

Submitted in partial fulfillment of the requirements in Research 1 Alubijid National Comprehensive High School Special Science Class Alubijid, Misamis Oriental January 8, 2014 Mrs. Ma. Romila D. Uy Research Adviser Abstract Battery is a device used to store electrical energy. Battery can also be called a cell in which the reaction between two different substances can be made to occur in such a way that some of the chemical energy is converted into a useful electricity. Since its invention and inception, battery has become the most common power source for many household and industries. The vinegar battery is constructed out from simple components or materials. Adding an amount of vinegar to a strip of different metals like copper, from copper wires and zinc, from nails can form a simple battery. This battery has a low amperage output which can supply power on a low amperage/low voltage device like a calculator. It is easy to construct. The following steps should be followed in constructing the vinegar battery: 1. Prepare all the materials needed like: * Vinegar * Strip of Zinc from nails * Strip of copper from copper wire * Vinegar container (non-metallic) * Multi-tester 2. Place the vinegar inside the container. Make sure that it is deep enough to suspend the two different metals on it. 3. Cut a piece of copper...

Zinc sulfate may be substituted for the sulfuric acid. The Daniell cell was a great improvement over the existing technology used in the early days of battery development. A later variant of the Daniell cell called the gravity cell or crowfoot cell was invented in the 1860s by a Frenchman named Callaud and became a popular choice for electrical telegraphy. The Daniell cell is a type of electrochemical cell invented in 1836 by John Frederic Daniell, a British chemist and meteorologist, and consisted of a copper pot filled with a copper sulfate solution, in which was immersed an unglazed earthenware container filled with sulfuric acid and a zinc electrode.

...• The development of a cheap source of energy that was virtually unlimited, yet small enough to fit in a pocket We already have the beginnings of this technology in our world today. A battery the size of a cellphone battery but the thickness of a Styrofoam plate has been developed by an inventor here in the US recently. If coupled with some form of pocket clip solar collector it would be limited to voltage and wattage for small electronics only but virtually unlimited as far as replenishable usable power. Benefiting from this would not only be a society that “demands” faster technology with a more reasonable price tag to make their everyday life easier, but the business world as well would reap rewards. Those businesses that relied on field equipment utilizing small power technology could stay in the field longer, travel farther and complete their job quicker than with older equipment previously used. This would relate to more profit to the bottom line, customer retention increases and employee retention due to less job stress. A win-win for everyone involved. The only downside to smaller technology items is progressive use of automation for manufacture and the loss of jobs in the workforce. • The development of a “transporter,” similar to the one used on “Star Trek,” that could ship both goods and people across the street or around the world cheaply and instantaneously A transporter to move goods and people whenever and wherever needed on this planet or even to another...

...The usage of "battery" to describe a group electrical devices dates to Benjamin Franklin, who in 1748 described multiple Leyden jars by analogy to a battery of cannon[2] (Benjamin Franklin borrowed the term "battery" from the military, which refers to weapons functioning together[3]). Alessandro Volta described the first electrochemical battery, the voltaic pile in 1800.[4] This was a stack of copper and zinc plates, separated by brine soaked paper disks, that could produce a steady current for a considerable length of time. Volta did not appreciate that the voltage was due to chemical reactions. He thought that his cells were an inexhaustible source of energy,[5] and that the associated corrosion effects at the electrodes were a mere nuisance, rather than an unavoidable consequence of their operation, as Michael Faraday showed in 1834.[6] Although early batteries were of great value for experimental purposes, in practice their voltages fluctuated and they could not provide a large current for a sustained period. The Daniell cell, invented in 1836 by British chemist John Frederic Daniell, was the first practical source of electricity, becoming an industry standard and seeing widespread adoption as a power source for electrical telegraph networks.[7] It consisted of a copper pot filled with a copper sulfate solution, in which was immersed an unglazed earthenware container filled with sulfuric acid and a zinc electrode.[8] These wet cells used liquid electrolytes, which were prone...

Volta was a physicist, chemist, and a pioneer of electrical science. He contributed to today by inventing the electric battery, discovering methane and internal discussion. He not only did those things he was also able to apply part of his last name as part of potential energy term for the battery “Volts.” Volta was born in Como, Lombardy, Italy on February 18, 1745. His parents’ names were Donna Maddalena, who came from a family of Counts and Filippo Volta, who came from a noble lineage. His parents had seven children who survived childhood....
