Getting free electricity gas station opened in Cologne

Getting free electricity gas station opened in Cologne

The energy company Rhein-Energie has opened near the new market, a first free charging station. The gas station has been named Tank and offers not only can fill up for free electricity but also to try out an electric car. It can be between five electric vehicles of the French electric car manufacturer Mega elected including a mini truck. One of the electric car is eCity the Mega and is an ideal vehicle for the city. It has a maximum amount of 64 km / h during the range on one battery charge to 65 kilometers.

The Mega eCity can be just like the other four car models for 5.50 euros per hour and 5 cents per kilometer to be tested. The French company has an annual production of 15,000 units of its electric vehicles. The electric cars are like gasoline cars but have a powerful electric motor. be made available to the vehicles of the company Carsharing. It may be the same two cars at the gas station charged with new energy. According to Rhein-Energie, the energy is in the service station from a hydroelectric plant, and therefore was not only carbon neutral but also environmentally friendly.

Toyota secures lithium deposits

The Japanese carmaker Toyota is expecting a boom in electric and hybrid vehicles and has therefore secured a precaution lithium mining rights for a salt lake in Argentina. The trading subsidiary Toyota Tshusho and the Australian mining group Orocobre will promote a joint venture from the year 2012 in the salt lake Salar de Olaroz valuable lithium. The delivery will amount to two years later, the company says each year to 15,000 tonnes of lithium.

This amount would be enough to produce three million hybrid cars. The participation of Toyota Tshusho in the joint venture will be supported by the Japanese Ministry of Economy, Trade and Industry (Meti) at 25 percent. The global lithium reserves are limited and it is not surprising that the automaker slowly back up mining rights by not falling into the grave situation as the solar cell manufacturers with the raw material silicon. The solar cell manufacturers had not expected such a strong demand and high prices then had to buy the silicon.

Fraunhofer Institute relies on electric car batteries

The Fraunhofer Institute is a focus on the development of electric car batteries and wants to set up a new working group. The scientists of the locations of Erlangen and Nuremberg plan the development of storage systems to be integrated in electric cars. As part of a European project is currently being worked on it for drives to achieve an improvement of electric cars. The electric motors are to be improved in efficiency by 30 percent.

The electric cars erfeuen Although increasing in popularity but the short range and the still rather high purchase prices or deter the majority of motorists. It will succeed only the breakthrough when the range and performance is increased significantly. Currently have to pay for an electric vehicle with at least 100 km range around 15,000 euros. The Twike and CityEL are the most successful electric vehicles on the European market electric car. Hand, the CityEL are acquired for 4,000 euros.

Researchers develop body parts as a battery

The researchers at the University of Imperial College in London are currently working on developing a new composite. The composite is made of carbon and should be able to store electricity. The material should also have such a low weight that you can use it for body parts and use. In a test project in cooperation with the Swedish automaker Volvo is the boot floor is made for installation in a hybrid car. The boot floor is to relieve an electricity storage, the battery.

According to the scientists, it is possible in the near future, that roofs, hoods and doors are made of the composite. If that does innovative energy storage technology, then it would be possible that the heavy normal batteries could be redundant. As a model could housing of mobile phones, laptops and GPS devices are also made of this material and tap them for their electricity. But it will probably still take some years to mature, the new composite material and comes on the market.

Better Place electric car developed gas station

Better Place electric car developed gas station

The technology company Better Place has developed an innovative gas station for electric cars and in the Japanese city of Yokohama to the public. It is at the gas station for a battery exchange station which allows the rapid exchange of empty batteries, and therefore brings a high level of time savings. The battery change is to last only two minutes and was the prototype of the changing station demonstrates impressive. The battery is automatically changed and means a great deal of time in comparison to the hours of charging power to a power outlet. The changing station has been built on a simple principle. The electric vehicle is traveling on a bridge on the rails there are two sleds. The first carriage is the Swap of the empty battery charge and solve the battery holder. After the battery is moved to a charging station. The second sled at the same time supplies the electric car with a full battery.

Pitching is an area as required for a normal gas station but it is a large stock of adequate size for the charged battery and the recharging required. The concept aims Better Place to an international recognition and success of electric cars. The limited scope could be solved with comprehensive travel and recharge the current vehicles longer distances. The manufacturer has with the countries of Denmark, Israel, California and other states and regions have already agreed partnerships.

In the framework of cooperation to the charging stations are built across the country. The gas station is to purchase their electricity to recharge the batteries from renewable energy sources and therefore has solar panels on the roof. There currently is not known whether the charging system will prevail at all because that it must be accepted by car manufacturers. Up to now the only car company Renault-Nissan as a partner. The automakers hope for a development of current battery technology which the problem of limited coverage is to be solved.

Mennekes relies on electric car market

The medium-sized enterprises Mennekes has worked for a year to develop a system which consists of a charging socket and charger. The system is to combine electric cars with charging stations. By charging electric vehicles can refuel not only with new energy but it is also an accounting of energy consumption. The innovative charging system has already achieved a high degree, as Chancellor Angela Merkel and the CEO of RWE and Daimler could photograph it.

In Berlin and Aachen there Mennekes supported pilot projects launched with the sophisticated innovative Ladesteckersystem. It has been submitted for standardization and will be according to the ideas of the family business into a global standard. The German and European body behind the development of charging system.

Against the Chargers from Israel and Japan have also been submitted for standardization must Mennekes now claim. According to company president Walter Mennekes to the Handelsblatt (Online edition 19.05.2009) system that is superior to the other two loading systems because the charge is four times faster. In the autumn of this year decided that Stromladesystem is to become the world standard. If the Mennekes system enforces this means for the company from the Sauerland a new multimillion dollar market as electric cars in the coming years will grow in importance.

Lenovo ThinkPad T61 Review, Via: laptopsbattery.us blog

Lenovo ThinkPad T61 Review, Via: laptopsbattery.us blog

lenovo-thinkpad-t61-laptop

ThinkPad T61 14.13 widescreen notebook

Important to note is that this review covers the 14.13 widescreen version of the T61 series. As with any laptop model series, there are going to be widely varying configurations you can choose that will greatly affect system performance.

Specs:

Processor: Intel T7300 Core 2 Duo (2.0GHz, 800MHz FSB, 4MB Cache)

Graphics: Intel GMA X3100

Operating System: Windows Vista Business

Display: WXGA+ 1440 x 900 (LG screen)

Hard Drive: 100GB 7200RPM (Seagate Momentus 7200.1)

Memory: 2GB (1GB x 1GB), up to 4GB max

Ports: 3 USB 2.0, 1 FireWire, Monitor out, modem, Ethernet, headphone out, microphone in

Slots: 1 PC Card Slot, 1 ExpressCard slot (optional media card reader and Smart Card reader)

Optical Drive: Ultra-slim Super-Multi Drive

Dimensions: 13.23 x 9.33 x 1.09 - 1.263 (335mm x 237mm x 27.6 - 31.9mm)

Weight: 5.1lbs

The good: Internal roll cage protects LCD; 802.11n Wi-Fi for faster wireless throughput; very small A/C adaptor adds little to overall travel weight; Intel's Active Management Technology provides remote support.

The bad: New Centrino technology doesn't offer outsize performance gains.

The bottom line: Lenovo's 14-inch ThinkPad T61 shaves a few millimeters off the company's more mainstream R-series laptops, but still boasts the same, solid ThinkPad DNA along with IT-friendly features by way of Intel's new Centrino Pro platform.

Design and Build

The ThinkPad T61 is a premium product with a durable build, it is geared towards business users or simply those willing to pay a bit more to get something that won't fall apart after 1-year of use. For somebody that travels a lot or relies on their notebook to earn a livelihood, the build and reliability factor is probably more important than having the latest and greatest components inside.

The keyboard remains the same between the T61 and T60 meaning it's once again excellent. The only difference is that now there's more room on the keyboard side areas since the notebook body is wider, the speakers have been relocated to this extra real estate. The keyboard is spill proof and has two drain holes to make sure if you do happen to spill your morning Starbucks coffee, the liquid is carried away from sensitive components and out through the bottom of the notebook.

The hard drive is protected within the magnesium roll cage and shock mounted. Even if your T61 is dropped the included Active Protection System (APS) software will work with the on board accelerometer to detect a fall situation and end hard drive activity to prevent data loss.

Screen

The new widescreen format screen for the 14.13 T-series is either good, bad or somewhere in between depending on your personal preference. Lenovo will try and convince you widescreen offers more screen real estate and so it's better, the reality is the guys making the LCD screens are forcing it down the throats of the PC manufacturers because it's cheaper to make widescreen LCDs.

The particular screen I got is a WXGA+ resolution (1440 x 900). It provides easy viewing and you can fit a good amount on the screen, so no complaints on that front. The screen is crisp and there are no issues with graininess. The matte finish ensures there's little to no glare in office lighting situations.

Processor and Performance

The ThinkPad T61 now uses the Intel Centrino Duo (Santa Rosa) platform. You get a faster processor front side bus (800MHz), more processor cache (4MB) and an improved integrated graphics solution in the form of the Intel X3100. If all that talk is nonsense to you, then suffice it to say the T61 offers newer and better processing components than the T60. Will this performance be perceivable in helping to run MS Word faster? No of course not, but certain processor intensive tasks such as encoding video will be faster. And even if you won't be utilizing every ounce of processing power, just knowing the processor is faster and you're on top of the game is enough to make people like myself want to buy it.

Battery Life

One thing that's always a concern with a new platform is battery life. Reading the first reviews that came out about the T61 sounded like gloom and doom with reports of 2 hour battery life. It seems most of the initial reviews were done using very power hungry dedicated graphics solutions and with a 4-cell battery.

I had the opportunity to test a larger 6-cell battery on an integrated graphics system, and got 3 hours and 41 minutes of battery life under what I would deem normal usage. I was using the T61 with screen brightness set to half or lower, Vista battery optimized setting, wireless off to get this number. In a torture test, I set the screen brightness to top level, put in a DVD (Stargate) and played it until the battery hit 5% and the PC went to sleep – which happened after exactly 2 hours 15 minutes. I wouldn't call that bad, it'll get you through most movies.

The downside of a 6-cell battery is that it sticks out of the back (see pics) and weighs more, but I'm always be willing to carry a bit more weight for an extra hour of battery life. A positive comment that should be made is the power adapter is nice and small, it's actually the same size as the X60 ultraportable series adapter.

Keyboard / Touchpad / Pointing Stick

The ThinkPad T-series hasn't changed too much over time, and that's a good thing, there's no use changing something that's just right. The ThinkPad keyboard is one of, if not the best, notebook keyboards out there. There's zero flex, every key feels individual, every key has great travel/feedback and the keyboard is full-size.

The T61 has a pointing stick, I love using this and find it much easier than the provided touchpad it makes it so you can move the cursor around the screen without having to lift your hand from the keys, a much faster and easier to control style of input. But the great thing is that if the pointing stick isn't your cup of tea then you've got the touchpad as well.

Wireless

The ThinkPad T61 uses the Intel 4965 wireless chip that offers 802.11 a/b/g/n wireless reception. All of your bases are covered there, and the greater range 802.11n offers is on the table if you have an 802.11n router. The range of the ThinkPad is theoretically greater now that the lid material has changed to plastic too. The antenna is run up through the lid for better reception you see, and the new lid material allows radio waves to reach the antenna more easily. I was only able to test up to 100-feet away from my NetGear WGR614 802.11g wireless router, which I despise for its bad performance and tendency to drop connections, but the T61 worked just fine with it and I never suffered a connection drop and throughput was consistently good.

Turbo fuel-efficient

Turbo fuel-efficient

While high oil prices, as we too concerned about the way to look also on the hydrogen fuel cell, hybrid and other advanced technologies, the German mechanical engineers are still "conservative" in the traditional internal combustion engine to make a fuss. They are not stubborn, when the Germans applied sophisticated engine technology, the leading small-displacement engine with turbo technology, much as unexpected effect – caused by low fuel consumption of small displacement, turbo brings the sufficient power, the engine weight reduction effects caused by fuel-efficient is immediate.

Last year, the 62nd Frankfurt International Motor Show, Mercedes-Benz introduced a pilot model F700, which is a representative of the future Mercedes-Benz S-class luxury of new technology concept car. The geezer on the next cars, people's most surprising is not it a luxury configuration, nor is its leading security technology and control methods, but the first time to equip a pair of displacement Jin You 1.8L petrol engine. Luxury sedan configuration 1.8L engine? Pair of small-displacement engine and was able to output 235 horsepower, the equivalent of a S350 power, it is surprising that its fuel economy is close to 40mpg, 100 km fuel consumption is only 5.3L, while CO2 emissions are also considerable well, only the emissions per kilometer 127g, significantly lower than the existing most advanced internal combustion engine.

We know that low-speed diesel engines, big torque, while the petrol engine power high-speed high, DiesOtto engine is designed with variable compression ratio, low-speed diesel engines used similar methods of work with high compression ratio, high-speed Another question gasoline mode to run. Pair of Mercedes-Benz F700 engine is the paramount concern, how can 1.8L 4-cylinder 3.5L engine output power from conventional engines, but can keep a small displacement engine, fuel economy? The answer is the application of the turbo engine, Mercedes-Benz F700 is a dual turbo technology.

From the supercharger to the turbo

Most people think the role of turbocharger technology is to enhance power, indeed since the Saab to the technology from aviation to automotive applications, the turbo power is linked with the upgrade. The Mercedes-Benz has long been on the turbo technology is not a cold, has been supercharged stick to the line, in fact, supercharger and turbocharger has its drawbacks, supercharged power transfer can not take into account the high output, while the turbine by pressure in the low turn out is weak and lacks the smoothness of power output. Although the technology has to overcome these shortcomings, it is clear that the future of engine technology in addressing the shortcomings of turbo easier.

Thus began the development of Mercedes-Benz turbo engine, and now the new flagship Mercedes-Benz S600, SL600 is equipped with a 5.5L turbocharged V12 engine. Earlier this year, test drive Mercedes-Benz SL600 in the U.S., when faced AMG CEO Volker Mornhinweg, he almost invariably sense to us that: AMG decades has been indulging in engine technology, from supercharged to turbo; but if we another choice, so I think we will not stick to the road supercharger.

The Mercedes-Benz R & D department is responsible for high-level Thomas Weber told the media revealed that in the next two years time, that is the end of 2010, Mercedes-Benz cars will be fully into all the turbo technology. According to the requirements of the European Commission, European automakers have continued to improve the environmental performance of the engine, the car in 2012 from the 178g/km carbon emission reduction to 138g/km, if not meet this standard, the European Commission will be punished. The Mercedes-Benz to turbo technology to the attention of the unprecedented height, Thomas Weber clear: the future, more displacement is smaller, lighter, better fuel consumption and outstanding performance without compromising in the new engine, gradually adding the cars. Increase with a small displacement turbo fuel and technology to solve environmental problems, is the F700 concept car R & D ideas.

Obviously, turbocharged gasoline engine technology is the future that came out.

BMW also play turbo

If you are an advocate of naturally aspirated engines, turbo-charged and sent in a time when controversy, BMW is definitely your greatest argument. BMW diesel models in addition to its models are equipped with all of its naturally aspirated gasoline engine. BMW's decision to betray the naturally aspirated, but also had to do this, the potential for civil naturally aspirated engine has been completely excavated, though the BMW's engine power output is not worse than rivals, but also look for future power system way out.

Turbocharger turbine is the most unpleasant place to slow late, because there are some quality turbine, from the foot down to the turbine reaction step on board a short time, this power is usually of delayed impact drivers mood. The solution could be to create as small as the lighter the turbine, while BMW's approach is to use twin-turbo: the straight six engine, the two smaller turbochargers each supply compressed air for the three cylinder, rather than and then only with a large turbocharger compressed air supply to all cylinders at the same time. Dual turbochargers important advantage of the lower turbine inertia, even if the driver applied the gas pedal on a very small force, the engine can respond naturally aspirated performance closer.

The new inline 6-cylinder twin-turbo engine and power quite naturally aspirated 4.0-liter eight-cylinder engine than the light weight of about 70 kilograms. The addition of turbochargers to improve 3.0L straight six, 41 hp, while torque is 85 Nm to upgrade! Department of cars to BMW3 example: Twin Turbo models from 0 to 100 km / hour and more than half a second faster in the second high gear acceleration from 80 to 120 km / h was also significantly reduced, the most powerful The naturally aspirated model BMW 330i 8.2 seconds to complete this process takes, but this new model is now just 6.3 seconds.

Usually turbo engine displacement than the naturally aspirated engine with higher fuel consumption, BMW's solution is to use high-precision fuel injection technology and dual-turbocharged combination, this high-precision fuel injection system with power unit than the traditional turbo engine to reduce fuel consumption by about 10%. Moreover, this technique also the concept of lean burn direct injection provides a starting point, BMW's engineers can gain experience from which to successfully optimize the fuel consumption of other power systems.

Small-displacement turbo is the future trend

Volkswagen is the first small-displacement turbo-charged the practical depot, equipment in the GOLF GT's 1.4L supercharged engine, the first two-eat crab. With the help of turbo technology, this pair of displacement of only 1.4L engine maximum power output to 170 horsepower, torque is reached 240N? M, this is already a 2.4L naturally aspirated engine output.

The face of double-charging technology to bring high costs, the mass was removed this vice engine supercharger, turbo retained to develop lower-cost 1.4TSI engine. Despite the supercharger removed and lowered the compression ratio, but made the maximum power after the 1.4TSI still 96kW/5000rpm, when the rotational speed can reach 1600 ~ 3300 220N? M of maximum torque, the data is still higher than many 2.0L naturally aspirated engine, even better. Volkswagen has just held a "Green Olympics" campaign, announced in the domestic production 1.4TSI engine and DSG dual clutch transmission decisions, 1.4TSI and DSG gearbox will be made in next year's Super Proton (parameter configuration Gallery) above. In addition, POLO, Octavia (parameter configuration Gallery) and Sunny (parameter configuration Gallery) also have the opportunity to use this advanced engine.

Mini electric cars come out

Mini electric cars come out

Miraculous advent of battery-electric vehicles only pocket size mobile phone

Only the size of the battery cell phone

Reporters in Nanjing Xin Jie Kou, first entered the MTR station, I suddenly saw a group of people around the platform, squeeze over to see a pretty girl is pushing the accompanying mini-electric car to attract interest. Soon, subway stop, she gently carry her to enter the subway car. Since it is electric cars that the battery has gone wrong? Some people saw a long time, but could not find. Pointing to the main bar girls car, said: "Here." Originally it was installed inside. Can not see, only the cell phone the size of the volume. Out of the subway station, the girl free and easy to step onto the truck will be gone.

Vehicle can be picked up gently with one hand

Found in the Investment Building, Zhongshan South Road, the re-launch of this car through the company, the company technical department engineer, said gold is the company's newly developed high-technology products, high strength aluminum alloy air welding, common materials strength is 7 times can load 80 kg, a charge can run more than 30 km. Ensure that the battery capacity consistent with white-collar working-class, the students travel to work needs. Carry her vehicle was a moment, stunned and mouth open Pakistan - a hand gently on carry her up!

Completely out of

Traditional electric car battery charging hard

City suffered the pain of the people traveling car expressed an unprecedented enthusiasm. Try to ride the spot required. Recanalization sales staff to explain the operation issues with enthusiasm, was also riding in a circle, with the uniform rotation control handle, light red light flash, the car turned up on smooth, feels really great.

Metalworking excited to introduce the traditional lead-acid battery electric bicycle generally in the 14-19 kg weight, heavy battery to allow more users have suffered the strain of the upper and lower floors suffered charge. Such a small pocket electric bike is a real portable means of transport. It can be folded into the subway, so you can easily shuttle between the city and can be placed in the trunk of a taxi and bus, to facilitate travel carrying purposes. And can you happen, you can gently mention stairs or the elevator, on the corner of the balcony or living room can be, do not have to worry about stolen away.

R & D process was very complicated

Metalworking frustrating introduction to the company in research and development process, can be said to have gone through difficulties. The first generation of products off the assembly line last year, R & D personnel in the light of the pursuit vehicle, with a disc brush motor, although the car lighter, but the electrical properties of unstable and battery power is very small, it continues the course just over 10 km . Travel far to meet the short-term needs. Although the second generation of the power increase, but the motor still does not improve, leading to practical function of product affected. R & D group of company leaders and decision of the final study: self-developed machine one brushless wheel motor. And again increasing the battery power. Brake system of the body and re-set, light open mold on the cost of millions. One-year-old, has finally successfully developed. Now in volume production market.

The world's leading technology products

Traditional environmental pollution battery electric cars much, but the key solution is to upgrade the battery core technology. In China, Beijing, Shanghai, Guangzhou, Shenzhen, Haikou, Changzhou all electric vehicles were introduced road against local regulations, medium and small cities across the country will be divided into different time periods the road against traditional electric cars. Lead-acid battery electric vehicles out of the market is a foregone conclusion. Lithium was recognized green product, it does not contain any heavy metals, the production process does not use water, the production of exhaust all subject to recycling, raw materials and lithium carbon-based. Not produce solid pollution. So, pay attention to environmental protection in Western countries to encourage green energy, electric bicycles are powered by lithium. Seen in this light, traditional electric cars will be replaced by lithium micro-electric vehicles.

Reperfusion produced lithium micro-battery-driven electric vehicles using lithium, the battery does not contain such as cadmium, lead, mercury and harmful metals in the manufacture and use and give up no environmental pollution. Under the frame containing the lithium battery, battery back into the big bar, you can directly plug the charger, front wheel hub brake with brake, rear brake only to establish security and stability. With the folding pedal device for a long time people in recreational sport and static electricity is insufficient long-range riding purposes. Products through national technical supervision, strict testing quality and safety testing, quality inspection report to obtain authority. Marked reperfusion lithium micro-electric vehicles based on traditional electric cars, find the quality of the cross point, the support points led the company in Nanjing and then rose through the ranks to the high-tech enterprises, the technology has been far ahead in the international.

Gold Industry Market blank

Green electric vehicles is considered to occupy the 21st century dominance of public transport vehicles is an indisputable fact. As a revolutionary high-performance environmentally friendly electric vehicles on behalf of progress - and then through the emergence of lithium micro car, the light effort, environmental protection, energy conservation, the characteristics of affordable, very popular among consumers, will be the city's new transportation highlights. Lithium-power micro-electric vehicles as a new industry is naturally enticing, full of hope and sunrise. In the domestic market, lithium micro-car market is in a period, in broad consumer market with unlimited number of cities, is still hard to find any sign of it. Market opportunities will be unlimited blank.

Recanalization lithium micro-car from the product launch date, several hundred times the daily volume of telephone counseling, more discerning business can not wait, have come glimpse of lithium micro-electric vehicles for hosting the Games, and on-site contract. At the same time the company introduced a number of further support through measures to ensure the correct order and sales agents throughout the rapid expansion of the market.

Following a motorcycle, after the glory of traditional electric car industry a golden opportunity, lithium micro-electric car will travel to the future of a revolutionary storm off the field.
