see, I am cuter, and I will be next generation of electric car

     Cars are used by us everyday, it is hard to inmagine life without cars. When we are enjoying the convenience which cars bring us, we also suffer the environment pollution it causes, in order to solve this delimma, scientists have try their best to develop a new kind of car which use electricity as fuel to keep the engine work. When there is a market, there will have competition, the following are the competition between two car companies which will the future trendency of car development.

    The Chevrolet Volt and Nissan Leaf will square off later this year in a battle that could determine the course of the 21st-Century auto industry.

   The Volt and Leaf electric cars take two radically different approaches to reducing oil consumption and emissions. The compact Volt will cover 40 miles on a charge and use an on-board generator for longer trips. The subcompact Leaf’s bigger battery pack promises a 100-mile range but won’t be capable of longer trips and will require hours of charging time after a long drive.

   The vehicles’ prices will also differ significantly. Nissan has announced the Leaf will retail for $25,280, after a $7,500 federal tax credit. Chevrolet has not revealed the Volt’s sticker price, but it’s expected to cost around $32,500 after the same tax credit.

  The Volt arrives in dealerships this November. The Leaf follows a month later.

  The cars represent multibillion-dollar bets by GM and Renault-Nissan. The winner will be the early leader in a new technology that’s expected to eventually dominate the worldwide auto industry.

  Electric cars have their ups and downsYou can’t get lower than zero. You can’t drive farther than forever.

   In a nutshell, those are the key selling points for the Nissan Leaf and Chevrolet Volt, respectively — the first new electric cars expected to sell in large numbers in a century.

   The cars promise different things, but they’ll be direct competitors as General Motors and Nissan-Renault try to define what a modern electric vehicle is, what customers should expect, how much they’ll pay and whether they should accept any compromises compared with conventional cars.

   The company with the winning approach will have an early lead in the technology likely to dominate the 21st-Century auto industry.

   The Leaf promise: Zero, zilch, nada direct petroleum consumption and exhaust emissions. Your car will never burn a drop of gasoline.

   The Volt guarantee: No emissions or oil used on the 40-mile and shorter drives that constitute daily driving for around 70% of Americans, and absolute certainty you’ll never be stranded by a dead battery.

    Which car is suitable for you? Which car will lead the way in future car market? Let us wait and see.

Choose camping generators according its appliance

If you are trying to decide what kind of generator you need for tent camping, you must decide what kind of appliances you will be running with it. For lights, small TV set and phone chargers, a generator whose power is 100 watt will do the trick. For running the small television, meanwhile, four or five light bulbs, a blender or toaster, you will want generator which is in the 2000 watt range. Above that size camping generators start to get heavy and bulky, and more noisy due to the increased size of the engine.

In addition to becoming larger, higher wattage generators become harder to pull start the bigger they get.

Choose a much quieter and cleaner generator

Inverter type generators produce a more pure sine wave which means cleaner power, unlike cheaper generators which create a choppy power signal, which can cause problems with many electronic items such as televisions and computers.

Inverter type generators such as those made by Honda and Kawasaki are typically much quieter than traditional generators and may produce less than sixty decibels. This will reduce the amount of noise you generate in a campground.

Instead of running multiple items it is easier and cheaper to use a 1000 to 2000 watt inverter generator and plug in those items such as toasters when they are needed and unplug. Remember you are supposed to be camping and not living just like you do at home.

Remember to use a fuel stabilizer or drain the fuel when you leave it stored for long periods. Otherwise carburetor will gum up from old gas and it will be hard to start.

Before the connection between magnetism and electricity was discovered, electrostatic generators were invented that used electrostatic principles. These generated very high voltages and low currents. They operated by using moving electrically charged belts, plates and disks to carry charge to a high potential electrode. The charge was generated using either of two mechanisms:

·             Electrostatic induction

·             The triboelectric effect, where the contact between two insulators leaves them charged.

Because of their inefficiency and the difficulty of insulating machines producing very high voltages, electrostatic generators had low power ratings and were never used for generation of commercially-significant quantities of electric power.

With the rapid development of technology, all kinds of modern generators are invented and used in every area of our daily life, and there is a lot of enterprise involved in producing generator, these generators offer families and companies comfortable and convenient life, which is especially important in today’s life. For example, now Generac is committed to produce generator to residential, commercial, industrial, portable and RV.

Here are the structure of generator, a conventional motor is rotated by outside working, that is, transform electric power into mechanic power after power on; whereas generator takes advantage of the change of magnetic flux to produce sensitive electromotive, that is, transform mechanic power into electric power, while general conventional generator/motor is of rotation type, that is, all mechanic power output by rotation work, or generate electric by the work of rotation; the generator/motor in current market normally apply Faraday’s law or Lenz’s law as generating or driven principle

The LEAP-X style engine which is produced by CFM company is regarded as the first one of the third generation of civil aircraft engines, and it is composed of high pressure compressor, high pressure turbine and combustion chamber.

According to report, in recent days, American general electric company proclaims that they are considering offering aircraft engine to China’s undergoing research of civil large plane with group of seven summit in France. Now Chinese business aircraft enterprise is putting in a lot of energy in developing and manufacturing the newest single aisle aircraft which is called C919, and it chooses CFM’s engine as the only cooperative enterprise abroad, according to the estimation of Chinese business aircraft enterprise, in the following 20 years, there is a demand of approximate 2000 aircraft in global market, and CFM is committed to developing and manufacturing aircraft, now it has become one of the most successful aircraft enterprise in the world.

Here is the current research of developing LEAP-X style engine, at the present, the compress ratio of single-stage turbine in core machine is 16, at the middle of 2011, they will test the compress ratio of double-stage turbine and the initial stage of design should be done by the end of this year, then CFM will finally decide whether to choose single-stage turbine or not according to the analysis of data. CFM enterprise says that they want to have higher heat efficiency, and they increase that through the increase of core machine’s temperature, at the same time, ensure the efficiency of turbine and durability. They also want to do them best in the following aspects, firstly, compared with CFM56style engine which is assembled in Boeing 737 series airplane and Airbus A320 series airplane, the engine’s oil consumption of LEAP-X style engine reduced by 16%, if they combine new aircraft technology, the oil-consumption can be reduced more. Secondly, at the aspect of high bypass ratio in improving combustion efficiency, they try to increase it from 5.5 to 9, that is an amazing progress. Thirdly, decrease the weight of LEAP-X engine significantly. 

Electric motor is widely used in our daily life, without electric motor, we can barely live for months. People are becoming more and more dependent on using all kinds of electric motor to make our life easier and convenient.

Today we are going to talk about how to buy an agricultural single- phase electric motor. Agriculture is the foundation of Gross Domestic Product, in today’s China, there is still sixty percent of people farmers, so how to improve the yield of wheat, rice and all kinds of vegetable is an important and urgent problem which should be solved as soon as possible.

There are two tips for buying single-phase electric motor, firstly, we should choose the single-phase electric motor according to the spindle speed of agricultural machine. Generally, when the spindle speed of agricultural machine is high, we should consider buy double-stage single-phase electric motor, on the contrary, we should buy four-stage ones. Those high spindle speed machine, such as grind machine, centrifugal machine, seal machine and so on, we should choose two-stage single phase electric motor for it, and those machine which has low spindle speed such as squeezing machine, package machine, we should choose four-stage single phase electric motor for it.

Secondly, we should ensure the power of electric motor according its working load, for those machines which are engaged in machining of bean milk and machining of almond, we should choose single-phase electric motor whose power is between 800and 1100 W, we should consider buying double capacitance single-phase electric motor whose power is between 1500 and 2200W for machines which are engaged in grinding flour machine and squeezing oil machine, and so on. In order to realize various functions and exert the efficiency of agricultural machine, we should choose four-stage double capacitance motor whose power is 2200W; choose the electric motors which have good reputation and high quality; buy motors according to the rated current and current which circuit wire can take, the rated current on electric nameplate should be lower than rated current on board and circuit carrying current, if it is higher, then we can replace bigger electric board and thick wire; contact with agricultural machine manufacturer and ask them whether they can change for a new one.

What can you do if you are out of power and need to charge your cell phone?  There are battery boosters, and fuel cell rechargers and now a new device that cranks energy with a yo-yo-like string.

The YoGen handheld charger for portable electronics was launched at CES and received recognition as a “Best of CES 2010″ item by Gadget-Gurus.

The 100 percent green, fully-sustainable device that creates levels of charge sufficient to ensure sustained use when a battery runs down. YoGen Sells for $39.95 and could come in handy in cases of a disaster or just when you forget to charge you phone. It works with most cell phones including iPhones, USB devices and Bluetooth headsets.

YoGen can echarge any small-to-mid-sized personal electronics device by offering the industry’s leading ratio of energy output to input.

Through repeated pulls on an attached ripcord, similar to the motion of a Yo-Yo, YoGen’s internal alternator generates power in to charge everything from cell phones, iPods, PDAs and MP3s to Gameboys, GPS units, cameras and other devices. The alternator interfaces with an energy-efficient electronic stabilizer and transmission to transfer linear kinetic energy through a patch cord from the compact, ergonomically-designed unit to the electronic device.

Horizon Fuel Cell Technologies developed a new product which was presented at CES Las Vegas, Nevada (Consumer Electronics Show).

The Singapore based Horizon fuel cell technologies is showing off the Hydrofill, a fuel cell system
designed for charging electronic gadgets at CES 2010.

The product will be released later this year and allows users to charge up their favourite mobile or small electronics with a hydrogen fuel cell.

The device extracts the hydrogen from water and stores it in special cartridges, which fit into the pocket size minipak. the minipak uses a USB port to charge everything from ipods and cameras to rechargeable batteries and GPS devices.

The process of turning water into hydrogen is very clean too, since its only produces water vapour as a result.

Horizon Fuel Cell Technologies, which first became known to the general public with an exclusive Gizmag story in 2006 about the company’s educational toy solar hydrogen car.
The Horizon toy cars quickly became the world’s largest volume-produced commercial fuel cell products and it is quite an irony that less than half a decade later, the company which launched with a toy car appears set to introduce genuinely disruptive technology into the home, finally enabling the long-touted futuristic vision of a hydrogen station in every home.

Whether you own an RV, or intend to buy one soon, you will need a reliable source of power for your travels. Portable generators provide an economical and effective solution to your electric power needs, on the road or at the campsite.

For many people though, purchasing a power generator can be an intimidating and confusing process. Here’s how to choose the right one for your power needs.

First, you need to determine the size of the generator for your RV by knowing how much power you will use. This will narrow down the choices you have when selecting a portable generator.

Start by surveying your RV for appliances that run on 120 volts. The TV, microwave and other kitchen appliances generally require the most power but smaller appliances can add up. Most RV lights are 12 volt but some may be 120 volt. Your RV air conditioner is the biggest power user.

Next, add up the power requirements, in watts, for all the devices that you are likely to operate at the same time. Wattage ratings are printed on light bulbs; other devices like hair dryers and electric heaters are also described by their wattage requirements. If the device doesn’t provide a wattage requirement, you can determine watts by multiplying volts times amps.

Be aware that some electrical devices have starting wattage requirements that are larger than the running watts, like the air conditioner. If so, use the starting wattage requirement for the largest of the devices you want to run and the running watts for all other devices. This is the minimum wattage you will need from a generator.

Now that you have determined your power needs, it’s time to look at the type of generator that will fit the bill.

There are two types of portable generators: contractor and RV. Contractor generators are generally inexpensive, very noisy, and not suitable for an otherwise quiet campground. RV generators are purpose-built, providing quiet, reliable power that your camping neighbors will thank you for. They are expensive but are well worth it in the long run.

There are a wide range of portable RV-type generators, with each manufacturer having a wide range of noise levels. Honda, Yamaha, and Kipor (see Resources section below) all make super-quiet portable generators. Match up your power requirements with the model that has the lowest decibel (a measure of how loud we hear noise) level.

Starting options for portable generators are either pull start, like your lawn mower, or electric start using a key. Generally speaking, electric start generators are available in the 3000 watt range and larger. If you have a bad back or just want the convenience, shop for the larger wattage generators.

There is even a wireless remote option that can be retrofitted to most electric start generators. It’s costly but can be very convenient if you don’t want to get out of bed, go outside, and turn off the generator.

Consider how long you will run your generator. Some portable generators have small fuel tanks, less than 1 gallon, while others have much larger ones, up to 5 gallons. Generally speaking, the larger the power output from the generator, the larger the fuel tank capacity. There are options though to add additional fuel capacity.

Think about how you will transport your generator. Larger generators weigh a lot, up to 175 lbs. with fuel. You can transport it in the back of your truck so be ensure to get the optional wheel kit for the generator and use ramps to make it easier to roll the generator in to the back of the truck.

If you have an SUV tow vehicle, you can have a platform built on the back of your RV to carry the generator. Never transport your generator in the back of your SUV. Gas fumes are explosive and in the event of a fender bender, you don’t want a 100 lb. chunk of metal flying in to the passenger area.

Getting a generator that can handle all your power generation needs is one of the most critical aspects of the purchasing decision.  Whether you are interested in prime or standby power, if your new generator can’t meet your specific requirements then it simply won’t be doing anyone any good because it can put undue stress on the unit and even damage some of the devices connected to it.  Unfortunately, determining exactly what size of generator to get is often very difficult and involves a number of factors and considerations. 

Making a choice amongst single phase, three phase, kW, KVA, welder, standby or motor starting generators can be mind-boggling. To prevent such confusion, this article was developed to help you get a better idea of how the sizing process works and some key things to keep in mind.  This is not a substitute for a certified electrician, which we always suggest talking to before buying, but it should provide you with enough information to get a solid understanding of some of the key things that are involved.

Generator Size Variations:  With the latest advancements in the field of electrical engineering, generators are now available in a wide range of sizes. Generators with power supply capacities of 5kW to 50kW are readily available in the personal and home use markets, while industrial generators are anywhere from 50kW to over 3 Megawatts.  Handy and portable gensets are available for homes, RV’s and small offices, but larger businesses, data centers, buildings, plants, and industrial applications need to use the much larger sized industrial generators to meet their higher power requirements.

Generator Sizing - How Much Power?:  Many people believe smaller generators can be used for standby electric power because they are not running all the time. This is not only a myth but can actually be very detrimental. Unfortunately, generator under sizing is one of the most common mistakes committed by buyers.  Not only does it involve the risks of damaging your new asset (the generator), but it can also damage other assets connected to it, create hazardous situations, and even limit overall productivity of the unit and/or the business relying on it.  If nothing else, the key thing to remember here is that more is always better than less.  

How to Determine the Right Size Engine or Generator: While there is no substitute for having a certified electrician perform an inspection and calculate everything for you, the guidelines below do offer some great starting points and should at least get you started in the right direction:

- Make a list of the items that need to be powered by the generator

- Make a note of the starting and running wattage of the respective items

- Calculate the total power requirements in KVA or KW

How to Find the Starting and Running Wattage: Getting the right starting and running wattage of the devices you intend to power is crucial for calculating the accurate power requirements. Normally, you will find these in the identification plate or the owner’s manual in the buyer’s kit of each respective device, tool, appliance, or other electrical equipment.

Ampere - Watt Conversion:  You may often find power requirements of tools stated in amperes. In order to convert the power requirement of a tool from ampere to watts, follow these calculations, or you can also use our handy conversion tool on our power calculator web page.

For resistive load: Wattage = amperes x volts

For reactive load: Wattage = (amperes x volts) x load factor

Power Requirement Charting: It often happens that you lose the owner’s manual or for some reason can’t find the power requirement specification of the tools and/or other electrical devices you’re running. Here is a sample power consumption chart that demonstrates some of the typical wattages used for common appliances and tools.  The chart is simply provided as an example to demonstrate how starting and running wattages differ, and how each device has specific consumption needs.  If you have questions over any particular items you can contact the manufacturer, consult an electrician, or contact us for a free consultation.

Different ways of Calculating:  Depending upon the type and number of devices, and the way the generator is scheduled to be used, there are a few different ways of calculating power requirements:

-  Single motor running 
-  Multiple motors running simultaneously
-  No electric motors.

Advantages of choosing the right size generator: Now that you have an idea on how to choose the appropriate size of generator to suit your needs, here’s just a few of the benefits obtained by going through that process:

- No unexpected system failures
- No shutdowns due to capacity overload
- Increased longevity of the generator
- Guaranteed performance
- Smoother hassle-free maintenance
- Increased system life span
- Assured personal safety
- Much smaller chance of asset damage

Where to Buy & Role of Dealers and/or Service Providers:  Since you are not only purchasing a substantial company asset, but most likely an item you will need to rely on for prime or emergency electrical power at some point, probably in a crisis, deciding where to buy is also a key consideration not to be overlooked.  The seller’s years of experience, whether they are a full service dealer or small commissioned broker, and so forth, all play a role.

Cardiff-based Tidal Energy Ltd is hoping to stage a year-long trial of its DeltaStream device off Pembrokeshire

A renewable energy company plans to test a new underwater generator just off the Pembrokeshire coast.

Cardiff-based Tidal Energy Ltd has planning permission for onshore works and is now seeking consent to place its DeltaStream device on the seabed.

A year-long trial is due to be held at Ramsey Sound, near St Davids.

The company said its tidal generator, capable of producing enough electricity to light around 1,000 homes, was at the cutting edge of green technology.

Invented by Pembrokeshire engineer Richard Ayre, each unit features three generators that sit on a triangular frame.

It is designed to be easily lowered onto and recovered from the seabed using a floating crane.

The company said its distinctive blade design enabled the turbine automatically to shed excess power, permitting consistently high energy conversion.

Planning approval has been granted by Pembrokeshire Coast National Park Authority for the onshore works.

The company has now applied to both the UK and Welsh assembly governments for consent for the offshore works which include laying a cable and positioning one DeltaStream device on the seabed.

Chris Williams, development director of tidal energy, said a “comprehensive” environmental impact assessment had been undertaken.

A public exhibition of the plans is due to be held later this month.

The company is hoping to start the trial in autumn next year.

Mr Williams said: “The next public exhibition is to update the local community on the project, and particularly to discuss and explain the findings of the environmental assessments.

“Areas that have been assessed are far-reaching, ranging from bird life, to mammals, tourism and ecology.

“We invite anyone with an interest in the project to come along and talk with us about the details of the proposed 12-month test.”

The exhibition will be held from 1400 to 1700 GMT on Friday, 20 November and 1000 to 1300 GMT on Saturday, 21 November at Curtis House on Bryn Road in St Davids.
