Mindset runs with solar roof

Mindset runs with solar roof

The Swiss company has developed with the same mindset electric vehicle fast sports car which has a solar roof. The car weighs less than a ton and comes to a top speed of 140 km / h. In just 7 seconds, he creates a speed of 0 to 100 km / h. For power supply a 70 kilowatt electric motor with lithium-ion battery has been installed. With one charge of Mindset is according to the manufacturer about 200 miles before it needs refilled with new energy into an electrical outlet needs.

Because the glass roof consists in part of the solar electric sports car, however, can certainly go longer distances than 200 kilometers. The vehicle was equipped with gas, brake pedal and an energy recovery. When stepped on the third pedal is a battery charge and it is recovered energy. As a special feature, the mindset will be charged even without power but only when the sun is shining.

The solar cells charge the electric vehicle with sunlight to practically free. If the battery is rapidly charged for it, the "Internal-combustion engine can be turned on. Under the current planning year, 10,000 units are being built but is currently the company looking for an investor to deal with the mindset to go into mass production to. The purchase price is estimated that by probably lie at 30,000 and 50,000 and therefore should not the electric sports car to be affordable for everybody woman.

Mitsubishi: increased capacity for electric vehicle

The Japanese automaker Mitsubishi is planning to media reports, an increase in production capacity of its electric car model with the unusual name "i MiEV" in 2011. The capacity will be doubled from 10,000 to 20,000 vehicles per year. Actually, the production capacity will be expanded this year from 2,000 to 4,000 units but since 2000 there are now pre-orders from business customers was probably now decided to increase production capacity significantly. Next year, the electric vehicle from individual consumers to be acquired.

In addition, starting in 2010 the electric car on an OEM basis to the French car manufacturer Peugeot shipped. Under a cooperation agreement with the lithium battery maker Energy Japan, Mitsubishi and GS Yuasa Corporation, the company will be set up next year a second production line for batteries. Every year, the factory now instead of 2,500 Shiga 5.0000 batteries from the tape and run with greater efficiency, a further 1000-2000 batteries are manufactured.

In Canada, the Mitsubishi "i MiEV" is introduced. A vehicle will be integrated into the fleet of the energy company BC Hydro Company of Vancouver. According to the plans of the Mayor to Vancouver to be the greenest city in the world and the introduction of the Japanese electric car model is an important part of implementation.

Karmann developed electric car

The insolvent manufacturer Karmann convertible operates according to a report in the newspaper "Welt am Sonntag" on developing an electric car. Is this the electric sports sedan, the E3 to a range of 150 kilometers and has to have a top speed of 140 mph.

The electric vehicle is not only for city driving but also long distances as they are designed to take commuters. Unlike the competition, the battery is installed in the subsoil. The environmentally friendly vehicle is made on behalf of the Oldenburg-based energy company EWE and October, six prototypes of the production line. At the Hannover Fair in about two weeks, the sports sedan E3 presented to the public.

The convertible manufacturer Karmann had made last Wednesday to file for bankruptcy because of an impending bankruptcy. The international automotive crisis and the sociality plan cost the company says are responsible for the step in the bankruptcy. Around 3470 people are employed by Karmann and would lose their jobs in an insolvency. Customer satisfaction and the reputation of the manufacturer are high. Therefore, the insolvency administrator is optimistic to find an investor. The amount of the financial needs of the prestigious company is not known. The company is to be preserved and the development of electric sports sedan E3 would help Karmann and thus to save the jobs.

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

+

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.

Justin IDF summit demonstrates the application of wireless power

Justin IDF summit demonstrates the application of wireless power

Imagine carrying a laptop into the airport or room, it no longer needs batteries, but give the battery. This is not a dream, August 22, 2008, Intel CTO Justin (Justin Rattner) in the current Intel Developer Forum to show the application of wireless power.

According to the Massachusetts Institute of principle raised by physicists, Intel researchers have been studying wireless resonant energy link (WREL) technology. Justin demonstrates without any plugs or wires to 60-watt light bulb lit the wonderful moment, fully meet the general notebook computer's power requirements.

According to reports, WREL's charm lies in its ability to secure, efficient wireless power. The technology relies on a set of strong coupled resonators, the principle is similar to a trained singer with a voice broken glass vibration. When faced with receiving resonator's natural frequency, energy will be effectively absorbed, the principle and the glass absorption consistent with its natural frequency of the sound energy the same.

If the technology can be achieved, then the laptop away from the transmitter resonator few feet away can charge the battery. While there are many engineering problems to be solved, but Intel researchers hope to find the final removal of mobile devices means a connection, and one day in the future to achieve the Intel platform, the wireless power supply.

Micro fuel cell system

Micro fuel cell system

As the portable electronics market in recent years, the rapid development and create a huge battery market opportunities to both types of secondary batteries have certain restrictions, making micro fuel cell is high hopes. This article introduces the micro fuel cell the major trends, and the commercialization of technological bottlenecks and market considerations.

In recent years the rapid development of portable electronic products, including mobile phones, notebook computers, personal digital assistant (PDA), and even digital cameras and video camera, etc., creating a huge market and business opportunities; However, with product enhancements, the system for power higher demand, a small and light, continued longer battery power, would be consistent with the requirements of all consumers.

Micro fuel cell system development trends

Theoretically, the energy density of fuel cell lithium-ion batteries for five to ten times more (varies due to different systems), is technically up to three to five times; In addition, fuel cell without power charge, completely free from the burden of charging and limitations, fuel supply, instead of just a few seconds, providing great convenience for users. Therefore, micro fuel cells, the huge advantage of market incentives and features, is bound to greatly accelerate the development of relevant technologies mature.

Variety of fuel cells, micro portable system the most appropriate, including proton exchange membrane fuel cell (Proton Exchange Membrane Fuel Cell; PEMFC) and direct methanol fuel cells (Direct Methanol Fuel Cell; DMFC), always within this two room temperature operate with small size, light weight, convenient cell stack design and so on. Among them, the direct methanol fuel cell with liquid methanol as fuel, the volume energy density of about three to four times the liquid hydrogen, hydrogen storage and transportation of much convenience and security, and get easy, low cost, so more portable electronic products needs. In addition, the use of micro-reformer (Micro Reformer) to produce hydrogen fuel conversion of methanol, micro fuel cells are the possible direction of development; below will focus on direct methanol fuel cell (DMFC) for discussions.

DMFC technology development bottleneck

The working principle of DMFC with proton exchange membrane fuel cell is similar only in the anode part of the fuel entering the methanol and water, and methanol fuel produced through the catalytic role of protons, electrons and carbon dioxide, the cathode reaction is identical with the hydrogen system . Micro fuel cells to enter the commercialization stage, it still faces a number of technical bottleneck to be overcome, the key question is as follows.

1, methanol through

As the methanol transmission through, making the battery through the voltage (overpotential) increased potential can be used more in 0.4V below the battery efficiency and thus limited, but also result in fuel consumption. Methanol through the current issue of the DPRK to solve two directions: the development of proton exchange membrane materials, so that with high proton conductivity and lower methanol permeability; control the concentration of methanol fuel, to reduce the amount of methanol penetration.

Second, the water overflow (Waterflooding)

DMFC anode to generate 1 unit of protons will be pulling out of about 2.5 units of water or methanol Daoda cathode, while reaction Ye Hui Yin Ji generate Shui, Guoduo water Jiangzu Ai Jin Ru catalyst Cengerzaocheng oxygen cathode Xiaoneng substantial lowering of the water Cheng Wei overflow phenomenon. This problem has to take the initiative to increase circulation of air flow away from the excessive water-based, but which would consume a large power system, so MTI developed body of membrane electrode (MEA) design method of control.

Third, performance

DMFC anode current efficiency is low, so including the NEC and other companies tailor catalyst or catalyst support for the development, try to provide greater power density; nano technology will help to improve the catalyst performance is noteworthy development . In addition, the system operating temperature affect the DMFC performance of another important factor, but the application to 3C electronic products, the need for proper temperature control, so the system of thermal cycling or thermal management is also now actively addressed.

4, fuel and water treatment

As the methanol concentration control properly can reduce the penetration of methanol, together with portable electronic devices do not allow the cathode resulting in leakage of water generated by the case, so the actual system to go through a lot of control logic to achieve the overall methanol and water supply and The purpose of the concentration of control of balance.

Active vs. Passive response to the portable product applications, current DMFC system development is divided into active and passive, the following are illustrative.

First, the direct methanol fuel cell active

Schematic diagram of active DMFC systems are attached. Anode operating at the appropriate concentration of methanol (about 3 ~ 6% vol), the additional fuel tanks for storage of a high concentration of methanol solution; anode cycle consists of three channels: high concentrations of methanol, cathode recycling water, and repeat the cycle of fuel; in under normal operation the anode through the fuel pump drive cycle and exclude Pf generated carbon dioxide, the fuel concentration is too low or the stock too low, the pumps were Pm and Pw by the high concentration of methanol and water to the anode cathode recovery, to maintain the battery the system. On the other hand, cathode oxygen can be forced from the fan or compressor air circulation.

The advantage of active DMFC can improve the system by high energy density of methanol concentration and cell stack design by increasing output power; disadvantage to using a number of energy components, reducing system net power output, more complex and takes up space .

Second, passive direct methanol fuel cell

Passive DMFC cycle mainly by gravity, capillarity or natural diffusion method to fuel and air delivery to the electrode surface reaction, at room temperature operating conditions. Such systems the main body for the membrane electrode (MEA) and the structure of the material design, by pro-hydrophobic material characteristics and differences in the concentration of fuel and water, control the diffusion rate, and minimize the effects of methanol penetration to enhance the energy density . However, the drawback of passive DMFC system is unable to provide greater power density, while technological threshold is very high.

The popularization of future trends

In addition to these key technologies to break through, the micro and small fuel cells to enter the market still face the costs, regulations, and user habits. DMFC is still very high cost of the current need to develop catalysts and related materials breakthrough. The overall system size or the size of the external auxiliary components and cost depends on a more creative and discovery, can DMFC popularize.

In addition, the toxicity of methanol fuel, and application characteristics of the product, prior to entering the commercialization of the test criteria must be certified by the relevant laws and norms. Currently, the U.S., Japan and many European institutions have been actively involved in the work of regulation, development and integration, the future development of DMFC is expected to be increasingly diligent.
