after all, you will use me some day.------- generator

     Generators are widely used in all kinds of machineries, people uses it to generate power and transports the produced electricity to consumer when they run into an emergency of electricity shortage. When people buys this kind of device, they should consider what kinds of generators they should buy, a brand new one or second hand one?

    There is a shortage of generators in the local market following the power outage in Sharjah, with people hiring the much-needed power generator from neighbouring Dubai and as far as
Abu Dhabi, industry sources say.

    A sales manager from Sharjah International Airport Free Zone-based company said a lot of people were enquiring about renting generators as there are no stocks for small- and medium-sized ones in the market.

   “We are not in the renting business, we sell generators and we did not notice any change in our business due to power shortage in Sharjah, but companies involved in the hiring business are benefiting a lot,” he said.

   “People don’t buy generators because they think this (the power shortage) is temporary and hope to use rented generators for maximum of two to three months. Big companies are buying new products, while smaller companies usually go for rentals,” a source from Al Binayah Building Materials Trading in Sharjah, said.

   “Of course, in the long-term perspective, it is cost efficient to buy a new generator,” he said, adding that the company has recorded a slight rise in sales after the crisis broke.

   A salesman from Sharjah-based Champions, which deals in generator renting, said at the moment, the company had only medium and big size generators from 40 KVA onwards for hiring.

  “We have run out of small generators and have only medium and big sizes. A 40 KVA generator will
cost you Dh4,500 per month as rent and Dh47,000 if buying a new one,” he said.

  Sami Jaber from Casablanca Generators in Sharjah said sales increased by 10 per cent compared to two months ago since the power shortage outbreak in the emirate. “Units from 30 KVA to 200 KVA of capacity are in big demand,” he said.

  A source from Al Qudrah Used Building Machines and Equipment said sales have significantly increased in the last three days. “Our business is at least 50 per cent up now. People are hiring all kinds of units — from 20 KVA up to 600 KVA. With a 20 KVA generator, you can power a small office or residential air-conditioner, while a 650 KVA unit can provide power to a 10-storey building.

  ”In fact, our suppliers are so happy with us because of the brisk business. We hardly have time to place new orders. People are not even asking for prices, let alone bargain, and they are ready to pay in advance. At the moment, we do not have small generators, all are rented out,” he said, adding that the boom is expected to last till September end.

  “We receive more than 100 calls a day from Sharjah, enquiring about all capacity generators, especially from the Sharjah Industrial Area,” a sales manager of an Al Quoz-based heavy equipment trading company said.

  “We have shortage in rentals and our stock is finished. At the moment, we have only one generator left. People are ready to pay double the price and we have a long waiting list,”
he said.

  “People normally prefer to hire used generators rather than buy new ones because the latter involves a lot of maintenance work,” he added.

  Some, however, said that the current boom could lead to a price hike in the rental and sales market alike. Currently, prices are 10 to 15 per cent less than they used to be back
in 2006.

  “Our suppliers are already hiking prices because of the demand. Many people are confused now and they are considering in investing in new generators. If the situation persists, prices will shoot up,” a Dubai-based sales manager said.

  Ashras Allam, general manager of the Abu Dhabi-based Al Masaood (Power Engineering Division), said his company had been getting a lot of enquiries from Sharjah for the last three days.

  “Though they ask for quotations only to buy new generators, there is a possibility that sales will go up because we know that it is very difficult at the moment to hire a second-hand generator as stocks are running out even in Abu Dhabi,” he said.

   When something is wrong in the circle, it wil cause evertything runs into a bummer. Choose the one which suits you best.

In an attempt to simultaneously save the environment and prove that opposites attract, Xcel Energy and Abengoa Solar have joined forces to produce the world’s first hybrid solar-coal power plant.

Located near Grand Junction, Colorado, the $4.5 million Colorado Integrated Solar Project intends to show that solar power can reduce the negative ecological impact of coal-fired power plants, considered to be the dirtiest of dirty power.

For a basic explanation on the seemingly complicated process, we defer to the good folks over at Earth & Industry:

In a traditional coal-fired power plant, coal that has been pulverized into a fine dust is burned to heat water until it becomes steam. The steam then turns the blades of a large turbine, which turns the generator and produces electricity. But if the fresh water is heated before it enters the boiler, less coal is needed in order to make the steam—and that is the principal behind Xcel’s Energy brand new solar-coal hybrid power plant in western Colorado.

No official word yet on a whether or not the obvious names for the new technology—be it “coalar” or “soal”—will take off.

One thing’s for sure—some environmental outlets consider the energy marriage to be a bit like putting lipstick on a pig.

According to Energy Wise:

As NASA scientist and leading climate expert James Hansen writes in his recent book Storms of My Grandchildren, “If we want to solve the climate problem, we must phase out coal emissions. Period.”

Hansen and others have shown that only if global coal emissions are completely phased out by 2030 could atmospheric concentrations of carbon dioxide be stabilized at between 400 and 425 ppm (which certainly seems unlikely from our current level of about 392 ppm), most likely averting some of the more dire climate scenarios. The U.S. currently gets about half of its electricity generation from coal; we better get started if we want that 2030 target to be remotely realistic.

Nowadays magnetic generator is widely used in daily life, because it is the greenest and newest generator which cause no harm to environment, it will become popular in the future.

The magnetic properties are utilized by magnetic energy generator to provide free electrical power to the household, this is essentially achieved by utilizing the strength of the magnets on the inside of generator, the major advantage for such an energy source is its permanent type, provides clean output, and environment friendly nature. This sort of energy to power the household energy requirements id almost free of cost using power generator.

The way that is used to generate a consistent current throughout the day is based on the concept of attraction and repulsion related properties of magnets. This generator has high efficiency features that provide efficiency at almost 500% as determined by experts. The energy generated by this power source can be utilized throughout the household without using any cables or electrical appliances, to be sure of the generator system running in a sound way, certain diagnostic tests should be performed on frequent basis. The generator does not allow any sort of harmful emission to spread into the surrounding atmosphere and prevents the spread of excess heat into the environment. The generator keeps working without being bothered by any sort of climatic changes happening around it. Certain high-speed types of magnetic generators are used in a variety of power appliances, and these generators are small and extremely efficient while generating power. Another advantage is that they are made of magnetic bearings, which does not require lubrication and have less maintenance issues and costs.

The distributed power applications require maximum use of these magnetic bearings for creating electrical power appliances like compressors that produce higher rate of energy per horsepower as compared to other types of generators. Whatever, a place where there is demand of electrical power but has problems related to controlling, the best bet would be to use these magnetic generators to perform this task. In case of extremely difficult off-grid locations, the magnetic power generators can do the trick to supply the required power. When a disaster strikes a certain location, these generators are extremely useful for rescue or reconstruction related operations.

The magnetic generator is widely used in today’s life, because of its high efficiency, low pollution and low cost, it will become the most popular generator in the world.

The magnetic generator belongs to the next generation of energy devices and is more efficient than solar and wind. The use of magnetic energy is not a new idea, but it is being developed for a long time as a real and visible alternative to conventional methods. You know, any device that reduces our dependency on the utility companies that supply our electricity has got to be good news, and building a magnetic generator is the best way to cut our power bill.

As is known to all, magnetic generated energy is one the best forms of energy which is being used world wide, for producing this type of energy, all you need is a permanent magnet generator, this is a special energy system which does not need big investment, and a permanent magnetic generator can be easily built and the energy used will be free of cost, the working principle of a permanent magnet motor is very simple and the maintenance cost is very low, once it is installed, the generator can be used for a long period of time.

The magnetic generator is considered the greenest of all the alternative energy systems. Here are the main benefits of building a homemade magnetic generator:

l      By using it, you can practically eliminate your electric bill or at least reduce it significantly.

l      Unlike other devices, it doesn’t produce any noise.

Nowadays everyone is trying to find a renewable source of energy, which is environment friendly. The appearance of magnetic generator can solve the existing fault in energy generating system, and it is a second to none generator which can save a good mount of money by using it in our home or office. In a word, magnetic generator is the newest and greenest generator which can lower our bill cost and cause no harm to environment.

Nano technology is regarded as the newest technology in 21 century, we are experiencing high development both in theory and practice, large amounts of new nano material and components have been developed, and show unprecedented retrospect in biomedical, military and daily life, but a lot of researchers focus on developing nano component which has high sensitivity and high performance, few of them focus on power system under nano size, but the nano sensor which is used in biology and military has large demand for this system. Generally, the power of these sensors are directly or indirectly from battery, if these sensors can supply themselves with power ,and the size of component and power become smaller, that’s what scientist has been doing for a long time, but haven’t realized it yet.

The invention of nano generator is probably a new chapter in the development of nano technology, the reason is as followed, firstly, it realize the combination of semiconductor and piezoelectric for the first time, and make the foundation for exploring the physical law in this process, secondly, it offers the specific technical routine for the leap from nano component to nano system. The development and study of nano component is the most advanced area in contemporary nano technology, because nano component has small size component which can be minimized to nano stage, low energy consumption, high sensitivity which macro component doesn’t have. Thirdly, it makes the theoretical foundation for realizing the minimization of entire nano component’s working condition. Fourthly, it makes a new area for the application of sodium oxide, currently, there is a fiercely decrease in the quantity of the article which is about nano bar and nano wire, and how to apply these technology into new area is still a new challenge. Finally, sodium oxide  has the distinctive biodegradability and biocompatibility, so it is used to sensitive and micro system in human body.

Nano generator is the application of new nano technology which can afford itself energy, it uses distinctive method to gather energy from human body or external environment and supply it to nano component and system. It can turn mechanical movement energy( such as the movement of human body, the extension of muscle, the change of blood pressure), vibrate energy( such as sonic wave of ultrasonic wave and so on) and water pressure energy into electrical energy and supply it to nano component, this kind of nano generator offers the theoretical and practical foundation for nano robot and wireless nano component which can realize self-power supply function, but there is still a long way to go before the practical application of nano generator, so we should develop several nano wire at the first and develop key method and technology for different power at the same time, we should study the fatigue and life problem of nano wire, and how to change fluid energy and sonic wave into electricity efficiently through nano generator; we should solve the seal problem of nano generator and its interaction with different organism.

In a word, the invention of nano generator makes the foundation of realizing integrating nano component and actually nano system, and we look forward to the widely application of nano generator in biomedical, military and daily life.

Preface: scientist has produced soft power rubber, when fold it, it can transform eighty percent of mechanical energy into electrical power. We can use this kind of material to make shoes, clothing accessories, and daily used stuff, even we can implant it into body as power.

“This looks like a pair of shoes, actually it is a charger”, if we remake the movie nation-produced 007, maybe we will have this sentence in the movie, the shoes which is transformed into a fan in the movie has been out of date.

Now scientist has manufactured a kind of tiny generator which we can put it in the coat, fix it under the shoe pad, maybe years later, it is not that funny when we pull a piece of wire out of shoes and use it for charging mobile phone, nowadays with the development of micro technology and material, people can charge for device at any time.

At the early of 2008, professor Wang from Georgia university of science and technology makes a kind of material which can produce power, at the best case, this material can produce 80 MW at every square, under the microscope, we can see every group of electric material’s structure likes two curve cones, when the material is folded and shook, two cones are compressed together and produce electricity.

The theory for this generator is piezoelectric effect, just like lighter. In 1880s, curie and his brother found some crystal can transform between mechanical energy and electric energy. Now in our daily life, there is large amount of piezoelectric material, from quartz to small component in watch, from aerospace to deep ocean.

Piezoelectric material has a big family, they have the common aspect which is that the centre of electric charge is not always at the same position inside lattice, although it appears that it is neutral, but the micro deformation of shape can change the distribution of electric charge, and in macro aspect, it turns out to be current.

According to the assumption of Macarl, those devices which can product electricity with micro deformation can produce electricity through the deformation of lung when somebody is breathing, and they can supply power for pacemakers.

Now the researchers hasn’t tested the biological safety of this generator on animals yet, if it can charge for mobile phone or iPod, it can be counted as valuable products. With more and more low energy-consumption in electric device, we are becoming more and more reliable to portable equipment, this kind of soft generator can bring us more and more freedom in using portable equipment.

The  first wind turbine generators rolled off the assembly line owned by GE Energy on May 10 at its factory in Nomura-Hai Phong Industrial Park in the northern city of Hai Phong.After a year of construction the factory is now ready for producing turbines generators for export.

The US$61 million plant, which is expected to create 500 jobs for local people, will export GE Energy’s turbines and services around the world.

The Hai Phong facility will provide an installation, maintenance and repair service for the components it produces.

GE Energy is a subsidiary of the global infrastructure, finance and media company General Electric, which employs more than 300,000 people worldwide.

Since 1960, GE Energy has provided technical support for a number of power generation projects in Vietnam. A recent survey shows that 8.6 per cent of Vietnam’s land mass is suitable for generating power from the wind.

Under a draft national power development strategy, currently being considered by the government, renewable energies will account for 5 per cent of the nation’s energy output by 2020, with wind and solar power accounting for half of all renewable energies.

ABB has introduced a new standard series of slip-ring generators designed to fit doubly fed wind turbines. The new generators cover the power range of 1.5 MW to 2 MW.

The standard base construction for different powers enables large-scale manufacturing, and the modular turbine interface connections can be changed to suit individual customers’ specifications, according to the company. Both air and water cooling are available, as is a 60 Hz version for North American installations.

Features of the new generator series include a patented rotor design with an optimized winding-end support ring.

An improved insulation level offers high-voltage peak integrity and allows the use of various types of converters, ABB says. The new design also incorporates minimized total harmonic distortion levels.
