SAM II EV Ecar - Innovative Technology and Ecology

SAM II EV Ecar - Innovative Technology and Ecology

The SAM was one of the first electric car as he arrived in 1993 to the market. From this long experience in the manufacture of electric vehicles will benefit buyers of this small car, because it contains a proven technology. The vehicle is aware of a small two-seater with only three wheels designed as a low power consumption is an important requirement for electric vehicles. Only small and light vehicles can provide great coverage and speeds suitable for everyday use, without it being to large batteries required. The SAM II EV has a range of 90 kilometers, for commuters and for use in city traffic is usually sufficient. Its maximum speed is 90 mph and is also designed for city driving and short distances on highways.

His energy of the SAM II refers EV lithium-polymer batteries, highlighted by both the heating and cooling of the vehicle and the heating of the windshield. The brushless drive motor is equipped with a permanent magnet and provides a nominal output of 11.6 kW, while peak power is 19 kW. The innovative energy-recovery technology in braking mode can increase the range of the SAM II EV even by 8 to 12%. The vehicle offers three different driving modes, Eco, sports and snow mode to be prepared for every situation on the road.

The charging of the batteries is possible at any standard Schuko socket. For a full charge the batteries need five hours, but after an hour charge time, 40% of the electrical charge reached. Thus, the SAM II EV refuels during working hours or the shopping spree at a charging station in the parking lot all by itself again in full. The power consumption of the SAM II EV is 8 kilowatt-hours for 100 kilometers. With a vehicle weight including the battery pack of 500 kg allows the vehicle has a payload of 220 kilograms and provides plenty of capacity for two adult passengers.

Volkswagen calls for electric car subsidies

The carmaker Volkswagen combines its research and development in electrical engineering with Wolfsburg, but will be centrally responsible. It is to be in the words of VW spokesman Christian Buhlmann clarified especially as the batteries can be grouped into units, such as the holding period is long, what they need and cooling take place as the power demand is. In addition to Wolfsburg Palo Alto is the second largest site, where about 100 people are employed with the electrical mobility and the Google navigation.

The personnel there to check how far can integrate lithium-ion batteries in electric cars. The new CEO Martin Winterkorn has called the policy in Europe for the promotion of electric mobility. The planned promotion in the U.S. and China are the main reason for this demand. According to him, significant investments to introduce the electric car technology would be needed. In China for buyers of electric vehicles up to 4,600 euros in grants which the purchase is affordable. The automaker is the electric version of the VW Golf and the electric car VW Up! in 2013 to introduce to the market.

Tazzari plans electric Cabriolet

The Italian electric car manufacturer Tazzari plans for spring 2012, the launch of an electric convertible under the name Tazzari Zero Roadster. The range should amount to the manufacturer's instructions with one battery charge to 140 kilometers and are the maximum speed at 100 mph. Since early 2010, the electric car will be purchased as a closed variant in Germany. In Silence by Germany GmbH in Salzgitter in the dealership Strube, the Tazzari and other electric vehicles to be admired.

The city car is the same as in Salzgitter in the capital in the government district in a showroom, where it waits for its buyers. At the beginning of may orders for the Tazzari electric car was abandoned. The crude oil will be exhausted in 20 to 30 years and by then, the alternative energy sources have become established. The electric cars can only be successful if a nationwide charging stations network is established and the range increases and the prices are reduced.

Multi-junction solar cell

Multi-junction solar cell

7 to 9 and July last year, in Freiburg, Germany (Freiburg) the Fraunhofer Institute for Solar Energy Systems (Europe's largest research center Fraunhofer-Gesellschaft 80 research institutes, one short FhG-ISE), the European record of solar cells increased by the 37.6% to 39.7%, after several efforts, and finally multi-junction solar cells a new world record - more than the U.S. Department of Energy Renewable Energy Laboratory (Department of Energy's National Renewable Energy Laboratory) 40.8% before.

Such a high efficiency multi-junction solar cell is mainly used to focus on photovoltaic systems (concentrating photovoltaic, referred to as CPV), direct conversion of sunlight as the sun, the source of power throughout the town. Will focus sunlight on a small (5mm) multi-junction solar cells, in solar energy equivalent to 454 can achieve 41.1% conversion efficiency, even in the higher energy 880 is still under solar irradiation measured 40.4%, the battery can be a wide use of sunlight intensity, and with more than 40% conversion efficiency.

Like the battery before the FhG-ISE, the new battery still use the deformation of the extension of the three junction structure and the lattice mismatch Ga0.35In0.65P/Ga0.83In0.17As / Ge (gallium indium phosphide and gallium indium arsenide deposited on Ge) layer structure. Compared with conventional solar cells, separation of the semiconductor material and there are no same lattice constant, we can only use the extension to combine the two layers of distortion, it is difficult to obtain high quality film, the other because of different between the two materials The lattice constant, combined prone to stress, resulting inserted row or other lattice defects.

By Frank, Dr. (Frank Dimroth) led group III-V Epitaxy and Solar Cells group, FhG-ISE to overcome the above difficulties and deficiencies limited to the electronic non-active zone, while the active area is relatively free of defects retained, which is to indispensable to achieve high conversion efficiency factor. "This is a good example and tell us how to use technological breakthroughs to control the crystallization of the semiconductor defects" Fraunhofer ISE's President Ike Weber (Eicke R. Weber), Dr. mentioned.

Multi-junction solar cell can be used in a variety of deformation of the extension group III-V compound semiconductors, the high efficiency of the battery structure formed by the appropriate materials can be divided into three bands of sunlight were to absorb. Researchers suggest that this is an important conclusion is that using a series of material connected to form the solar cell, its components will be the current minimum current that part to the limitations of the use of deformed extension of the battery Ga0.35In0.65P / Ga0.83In0.17As/Ge, can make the current matching, the complete output (multi-junction cell structure are produced close to three times the current of the battery), this is the battery can achieve high conversion efficiency of the important reasons.

Last year by the Fraunhofer ISE 37.6% conversion efficiency will be increased to 39.7% by adjusting the front-end structure of the metal thin wire has a lower contact resistance can pass large currents, therefore more suitable for concentrated solar constant of 300 ~ 600. Frank mentioned that the latest change in front of the metal thin battery is the graphics, and has a better quality film. In order for the technology and existing technology as a competitive, fast and feasible, Fraunhofer ISE in Germany Heilbronn (Heilbronn) of the Azur Space co-operation and technology transfer, also in Freiburg Concentrix Solar GmbH. "And the other focusing photovoltaic systems, our high efficiency solar cells is the most efficient way to reduce the cost of electricity" Fraunhofer ISE's Director, Dr Andrew Bate (Andreas Bett) mentioned. Fraunhofer ISE With the new battery to the goal of high conversion efficiency, a major step forward, and soon, the cost of photovoltaic power generation can compete with traditional power.

Dr Frank by changing the cell structure that will help make this type of battery has a long-term advantage, and to improve efficiency to 42 ~ 43%. Over the past 15 years, researchers at Fraunhofer ISE is committed to III-V family of multi-junction solar cell used in photovoltaic systems research focus from the beginning of the German Federal Ministry of Education (German Federal Ministry of Education and Research, referred to as the BMBF) for support Now while the German Federal Environment, Nature Conservation cum Nuclear Security Administration, Intelligent Energy Bureau (German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety, called BMU) to provide financial aid, scholarships for doctoral students, the future will be faster and better results to share with the world.

Sony a (alpha) DSLR-A350 Camera Review, via digitalcamerabattery.us blog

Sony plans to aggressively attack the market with a number of new DSLR SLR cameras is no secret. We had the opportunity to get their hands on the new Alfa 350 and Alfa 200’s again. Here are our first impressions of this very close family, including Sony’s interesting solution to the problem of prolonged exposure time cycle with Live View.

The Sony Alpha A350 offers new technology that makes images faster, easier and more familiar for users of digital SLR cameras for the first time. "According to the press release from Sony.

Note: Most of our findings are also applicable to the Sony Alpha DSLR-A300, also presented at the PMA and is essentially a version of 10-megapixel sensor of the Sony A350, with a lower price.

As for what Sony is promoting the main event of the Sony Alpha DSLR-A350 digital, including;

• Very high resolution 14.2 effective megapixels for beautiful images of the Convention detail, rich tones and bright colors


• Large LCD high-resolution 2.7-inch two-way leveling fire for freedom and comfort at different angles


• Quick AF Live View autofocus quick and accurate and responsive AF performance even with fast moving objects


• Improved in-camera Super SteadyShot to reduce vibration.

The Sony A350 features a new 14.2 megapixel sensor. There is a multiplier of 1.5 x focal length lens is used to obtain the equivalent field of view (FOV) in 35mm terms. Sony Alpha A350 SLR sweet with DT 18-70mm aperture-priority, that large JPEG, the size of 18 mm, 1 / 50 sec at f/5.6, ISO 200, WB Fluorescent central point cut from the lens.

The Alpha DSLR-A350 features a 14.2 megapixel CCD sensor, Live View, a vertical swivel screen, and like all Alpha DSLR-integrated sports anti-shake sensor offset establishments participating in the work aimed to set. It’s just the house or as a kit with the lens Sony DT 18-70mm.

Interestingly, this is not the main sensor, Live View facilities includes, but integrates a secondary sensor in the viewfinder. Sony has broken the traditional Live View systems in the setting of additional sensor in the viewfinder with a tilt mechanism that directs the light is, either through traditional eye. The advantage is not related to the conventional AF in Live View-bypass, so that the autofocus-A350 as fast as you normally would, without interruption or noise.

Making life even more useful view is that a retractable screen can be tilted vertically to allow wide-angle high or low easily. The A350’s screen can not turn the page, or turn on the face, but still a very flexible function.

Like all Alpha DSLRs, the sensor is located on the main platform for moving a mounted adjustable to compensate for camera shake. You do not see the effect on the viewer - or in Live View - but it gets to work with everyone who is going. This not only saves money, it means that you are the stabilization of the lenses that most manufacturers are not suitable as a benefit stabilization system as a standard 50 mm models.

Price of solar cells or bottom out

Price of solar cells or bottom out

Solar cells from the 4th quarter, began to cut production, the recent play seems to gradually cut overall effect, prices began to have stabilized, customers are asked about signing an increase in the frequency of a phenomenon, but solar industry said, because the prices close to low water level, current price contract to worry about the price rebound in 2009, but in a wait and see attitude.

Solar subsidy policy by the Spanish exchange in September and the financial turmoil, the two sides thereof facing the solar industry, orders for instant shrink dilemma facing the 4th quarter of unprecedented proportion of high inventories and cut-off, many small solar cells Factory 11,12 revenue contribution is minimal, and substantially cut the other side of the wave of layoffs is not stopped.

Continuing pressure to enlarge the environment, coupled with the financial turmoil caused by the financing, the price of solar cells fell sharply rare show from the August peak of the highest per-watt shouted 3.5 to 3.8 U.S. dollars, to 12 months outcry spacing of continually expanding, 2.1 ~ $ 3 per watt, the water level has a turnover of examples, highlighting the market clutter.

But 2.1 to $ 2.2 per watt, low price of water, solar-cell factory for most purposes are bottom of the price, if the source material procurement costs are not competitive, then the price of losing money is more likely the water level, in consideration of the new polysilicon material sources out of the situation is still poor, the source material prices fall again space is limited, therefore the price hit bottom solar cells, recently has attracted many of the module factory initiative to ask, hoping to sign at this price in a single year in 2009 contract.

Motech that appears in late December, the battery tends to decline in value does have a smooth trend, but their prices Motech level remained at 2.4 to 3 dollars per watt, the current prices are still unable to accept the low water level, in particular, Many signed their long, in fact, the price level are quite good, the quality requirements of the client better than the price gap.

Yi Tong pointed out that late December price decline in the battery does have the phenomenon of stabilization, which should be attributed to solar-cell factory in Taiwan to quickly adjust production capacity caused by the recent initiative to ask the client to sign a short about 1 year did increase the frequency, but consider the price of a rebound in 2009, the opportunity is still waiting to see, do not intend to rush contract, resulting in loss of future unnecessary post.

Solar industry said the price bottomed out yet wait and see but the demand stabilized, so the industry will continue as both sides expected the order to determine the capacity of the hands of utilization rate, estimated the short term will help to increase the stability of prices.

China: world’s largest electric car manufacturers soon?

China: world’s largest electric car manufacturers soon?

According to a recent study by management consultancy Bain & Co., China could rise up to the year 2019 the world’s largest manufacturers of electric cars. The reason is the substantial support from the Chinese government and therefore could only be strengthened developments in the Asian country. In March, China had presented a plan under which the country is to become a leading manufacturer of vehicles with alternative engines. Already in two years, the goal to strive for when you leave half a million vehicles a year and have the works on alternative drives.

Much of the Chinese people and that over 60 percent purchase low-cost cars. U.S. citizens, Japanese, Europeans and South Koreans decide only for an electric car if the price is right. The price is at 55 percent of customers a criterion of great weight. The Chinese overwhelmingly consider the right price, on the available charging stations and battery power.

The brand and the design have largely unimportant. According to the study results should demand per year, based on electric vehicles at 1.5 million units are located. The offer and the technological development would have a decisive influence on the demand.

Tesla Motors seeks to Germany

The U.S. electric car manufacturer Tesla Motors wants to open the year in Germany, two showrooms and interested parties will have the opportunity to test the Tesla Roadster to home. This was announced by CEO Elon Musk the online edition of the car magazine “Auto, Motor und Sport”. In the British capital London is already the end of June, the first European showroom will be opened. The cities of Munich and Monaco would then follow next. The electric sports car Tesla Roadster has been sold 500 times on a single charge and has a range of 150 to 200 kilometers.

The energy of the powerful electric motor draws from a 7000 high cell lithium-ion battery. The top speed is 200 km / h and the sports car can accelerate from 0 to 100m km / h in less than four seconds. The Tesla Roadster will arrive in an improved version with better performance on the European car market and cost around 100,000 €. The vehicle will be presented to potential buyers by teams on site. Already this year sales of 240 vehicles is planned in Europe. The Stuttgart automaker Daimler AG has joined a few weeks ago with a stake of 10 percent for Tesla Motors. In the past week had to accept the electric car manufacturer with a damper, as had 350 Tesla Roadsters are being recalled because of problems at the rear axle.

Mitsubishi shows the first electric car production model

The Japanese carmaker Mitsubishi in the Austrian city of Flachgau iMiev with the presented last Thursday, the first electric car of its planned high-volume production. Next year it will come on the market in Austria and then to a price equivalent to around 20,000 to EUR 25,000 have to be. The range of the electric vehicle is in relation with the hard-to-remember model name on a battery charge at 140 kilometers. The electric motor output amounts to 64 HP and the vehicle can be accelerated to a top speed of 130 mph.

Charging an empty battery takes from the normal household outlet for consolidated information about 7 hours. If however the battery in a power outlet as they are in business, the refueled battery charging time is only 30 minutes. iMiev come when and at what price the Mitsubishi on the German car market is not yet known. The electric car of the Japanese automaker is hard to distinguish between a normal small car and will therefore surely be able to sell well.

Lenovo ThinkPad T61 Review, @laptopsbattery.us blog

Lenovo ThinkPad T61 Review, @laptopsbattery.us blog

ThinkPad T61 14.1″ widescreen notebook

Important to note is that this review covers the 14.1″ 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: 13.2″ x 9.3″ x 1.09 - 1.26″ (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 14.1″ 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

+

lenovo thinkpad t61 battery, 14.1″ standard screens and 15.4″ widescreen + 14-inch wide lenovo t61 battery

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.
