MIT Researchers Print a Solar Cell on Paper

MIT Researchers Print a Solar Cell on Paper

We love the idea of clean and green fuel. But they come with certain disadvantages. First one is they are heavy on pocket of a commoner. Second disadvantage is their power conversion rate is quite low. Last one is you need storage space to save all the power converted by a clean and green technology compaq presario f700 battery. Now MIT researchers are coming out of solar cells printed on paper. Though the technology still has to wait for years before it can be converted into a commercially viable entity but it's an interesting development.

Scientists at the Massachusetts Institute of Technology have effectively coated paper with a solar cell. It is a part of a suite of research projects aimed at energy breakthroughs.

Susan Hockfield, MIT's president, and Paolo Scaroni, CEO of Italian lenovo 3000 g450 battery oil company Eni, formally dedicated the Eni-MIT Solar Frontiers Research Center. Eni financed the research project by investing $5 million into the center. This project is also financed by National Science Foundation. They are granting a fund of $2 million.

The MIT people took inspiration from the inkjet printer. They molded the solar paper panels on the similar lines. They used organic semi conductor material. The technique will be quite helpful in lowering the weight of solar panels. "If you could use a staple gun to install a solar panel, there could be a lot of value," Vladimir Bulovic, director of the National Science Foundation, said.

MIT researchers utilized carbon-based dyes. The efficiency of paper based solar cells is not great, at around 1.5% to 2%. But Vladimir Bulovic says that one can use any material if it can be deposited at room temperature. He further says, "Absolutely, the trick was coming up with ways to use paper," he said.

Prof. Karen Gleason is the head of the MIT research team. She has submitted a paper for scientific review but it has yet to be published. MIT and Eni have confirmed that this is the first time a solar cell has been printed on paper.

During the press conference, Paolo Scaroni said that Eni is funding the center because the company understands that hydrocarbons will eventually run out and believes that solar can be a replacement, although the currently available technology isn't sufficient enough.

Paolo Scaroni said, "We are not very active (in alternative energy) today because we don't believe canon lp-e5 battery today's technologies are the answer of our problems."

The Micron May Change the Way We Travel

The Micron May Change the Way We Travel

The carbon footprint that automobiles leave is about to change, and that change is going to happen much sooner than we think. While it is unlikely that the Micron will replace every car on the road, it will present a very interesting alternative to daily travel. This unique design is eye catching and more importantly hp pavilion zt1000 battery, totally emissions free. Make no mistake about it, the Micron is the future of the automobile.

While it would be nice to think that the environmental problems the world is facing would wake people up and get them to carpool, most people still insist on driving their own car to work every single day. The need for independence is understandable and appreciated, but if most people are doing nothing more than going to work and going home, why continue to waste gas and hurt the environment?

These are the direct concerns that the Micron addresses. Being electric, the emissions issues are immediately settled and being so compact, the congestion on the road will clear up. Imagine 4 vehicles that can hold up to two people that can fit into a parking space of just one car. The amount of city congestion that would be alleviated is simply staggering to even think about. The days of having the SUV in the garage for nothing more than shopping trips may be soon upon us.

The Micron is still being tested and is currently scheduled to be released in 2012 lenovo thinkpad x200 battery. Oddly enough, that is the same year that the Mayan calendar predicts will be the end of the world. While it is unlikely that the destruction that they have in mind will occur, the world as we know it is definitely changing. Instead of the end of the world, it could truly be a new beginning.

Packard Bell Dot VR46 in the test

Packard Bell Dot VR46 in the test

Packard Bell offers the dot VR46 notobook with a dual-core CPU and 11.6-inch display. For the look of the designer house of Valentino Rossi Motorcycle professional is responsible. ZDNet has been testing the device.

Because of the uniform components from AMD, Intel and Nvidia and the great price pressure is becoming more difficult for notebook manufacturers to differentiate their devices from the competition. Packard Bell has therefore teamed with Valentino Rossi, Michael Schumacher, the motorcycle scene. Whose house designer Aldo Drudi responsible for the design of the 11.6-inch Netbook VR46 responsible. The name is composed from the initials of the racer and his race number.

Whether Packard Bell so that the critical design breakthrough has succeeded is a matter of taste. Visually striking with VR46 namely only the lid, the black gloss has a colorful print is obtained, and the display frame Whether to display the logo VR46. It is with the device - whether positive hp pavilion dv8000 battery, but everyone must decide for themselves.

The components are hereby established for subnotebook ratios relatively fast: Instead of the often built single-core CPU is a dual-core 2-based to be used. Compared to a Netbook, it brings much more power. The VR46 is based also the Aspire 1810T, the Packard-Bell's mother Acer, which ZDNet has already been tested.

Input and interfaces

The housing of the VR46 offers no special features except the unusual appearance: everything is made of plastic, even the palm rest in carbon-look silver-colored and the hinges. It is stable and shows no weaknesses in processing.

The keyboard, which leaves some space between the big buttons allows comfortable typing. Getting used to is only one row of keys high enter key. The touchpad features multi-touch capabilities: allows dragging two fingers scrolling, the spreading and contraction controls the zoom.

The 11.6-inch screen replaces in 1366 by 768 pixels on - as much as most 13.3-inch displays. Unlike a typical Netbook display (1024 x 600 pixels) you can work with it without having to scroll too often have. In comparison to 13-inch monitors fell diagonal making itself felt in the form of a sharper Dastellung. The reflective coating causes as in many other devices annoying reflections.

The VR46 has three USB ports and a Gigabit Ethernet interface. Analog monitors can be controlled via VGA or digital via HDMI. An optical drive is not integrated. The device takes over WLAN 802.11b/g/n and Bluetooth 2.1 for wireless contact with the outside world.

The card reader accepts SD, MMC, xD, Memory Stick and Memory Stick PRO. An ExpressCard slot is not available, which limits the expansion possibilities.

1.45 kilogram weighs about 200 grams more than VR46 a 10.1-inch netbook lenovo ideapad y510 battery. The dimensions of 28.5 times 20.4 times 2.5 centimeters, of course, something greater.

Equipment

Instead of the low-power but slow atomic installed Packard Bell ultra low-voltage Core 2 Duo SU7300 chip (TDP 10 watts). He has two cores and is clocked at 1.3 GHz.

As the graphics used in many standard notebook chipset Intel GMA X4500MHD solution is used. In 3D Mark 06 it reaches 585 points. is also due to the low clocked CPU, the VR46 only for casual gaming. A 3D artist can not be expected given the small size also.

The RAM is rated with 4 GB. Because Windows 7 is pre-installed Home Premium 64-bit version, it will be fully utilized. The hard drive features 320 GB of disk space and works with standard 5400 revolutions per minute.

The integrated webcam offers a resolution of 640 by 480 pixels. In low light, the presentation is not very liquid.

Performance and battery life

The VR46 is a bit heavier and larger one atombasiertes Netbook, the PC Mark Vantage also shows that performance-plays in another league. It is also not far from a larger 13.3-inch model that uses the same graphic, but a higher clocked Core 2 Duo-hungry.

The removable 4400 mAh Dell Inspiron 1501 Battery powers the device for surfing the Internet at as much as possible dimmed backlight a good four hours of electricity. The VR46 takes between 18 to 26 watts. The fan is barely audible at moderate workload. Under full load, he turns up but clearly perceptible.

Software

Packard Bell liefet the VR46 with Adobe Photoshop Elements 7 and Nero 9 Essentials. In addition, Microsoft Works 9 and have Norton Internet Security 2010 (updates for 60 days). Latter is adopt its usual harnackig: The End of the program requires several mouse clicks.

Conclusion

The Packard Bell VR46 combines the utility of a notebook with the portability and battery life a Netbooks - attractive for 500 €. His shows connection to the racing there but only in appearance but not in performance. Because of the reflective display is necessary to make compromises in ergonomics. The eye-catching design is not for everyone take taste.

Patriot Memory announces fast SSDs with TRIM Support

The drives of the Inferno series reach speeds of up to 285 MByte / s and write rates of up to 275 MByte / s. They are available with capacities of 100 and 200 GByte. The price amount to € 650 360 respectively.

Patriot Memory has introduced the Solid-State Drive Series Inferno. The 2.5-inch drives to work with multi-level cell NAND flash, the sand-Force Controller SF-1222 and a 3-GBit/s-SATA-Schnittstelle with Native Command Queuing (NCQ).

The Inferno SSDs enable according to the manufacturer sequential read speeds of up to 285 MByte / s and write rates of up to 275 MByte / s. They are available with capacities of 100 and 200 GByte.

The used wear-leveling technology should, in combination with an ECC error correction and the sand DuraWrite Force technology for secure data transfer and long life. The mean time between failures (mean time between failures, MTBF) gives Patriot with 1.5 million hours.

The Newcomers also command the support of Windows 7 TRIM command, which ensures a continuously high performance solid state drive one. Without TRIM support for SSDs can use long after the performance in part to fall considerably. The cause of this phenomenon lies in the physical characteristics of flash cells, which are used for the SSD models.

Flash memory can be described only with no wait states, if those cells are empty. Since the operating system files but only delete the contents of the file system and the controller of the SSD of this deletion will notice anything, it must delete the access back into the cell, these first before he can describe it. With the TRIM feature shares the operating dell vostro 1320 battery system with the SSD controller, the data blocks are no longer used, so that it can delete the unused cells of rest, in order to later describe without loss of performance again.

Patriot returns the Inferno drives at once with a five-year warranty from. The 100-gigabyte model will cost 359 €, the 200 GB version € 649. Supplied with a 3.5-inch adapter for the installation of the SSDs in desktop PCs is included.

So they can use standard Office programs and web sites to visit fujitsu fpcbp196ap battery. To operate a computer connected via USB is necessary. The launch is scheduled for next year.

The research project at the trade fair has HyperBraille SightCity the functional model presented a portable computer with which blind and partially sighted people can tap into graphs and tables. Compared to conventional Braille display gives the user a structured overview of different levels of detail over the whole screen - instead of just a single line of text.

Last year, the researchers had already presented a prototype of such a display area. He lacked the time but the software necessary to control and software modifications for the use of common office and internet lenovo thinkpad x60 battery programs. Both were now completed.

As can process developed by HyperBraille surface display significantly more information than a Braille display and is also interactive, can not simply use the previously available on the market screen reader. Therefore, the project was the "Hyper Reader" developed a special screen-reader software. He also manages the information on the pin plate. The output surface it is divided into multiple areas with different information. For application programs such as Word, Excel or Powerpoint, the researchers have developed custom dialog boxes.

A future work or Lernplatz with HyperBraille sets for operation requires a jvc bn-v306 battery PC or laptop to which the hyper-surface Braille display is connected via USB. This also requires a separate power supply. Optional is a software for speech as a supplement.

The first Hyper-pin Braille plates to the event SightCity published next year. The cost of the display area, the developers hope to push in a few years to just over twice a Braille display can be. At the Federal Ministry of Economics and Technology (BMWi) funded project, the companies, and FH Metec Papen Meier, the Institute for Microelectronics Stuttgart (IMS Chips), and computer science institutes of the TU Dresden and the University of Potsdam are involved.

Nvidia GPGPU computing is on cards in front of Fermi-base

Nvidia GPGPU computing is on cards in front of Fermi-base

The Tesla boards c2050 and C2070 come with 3 or 6 GB of ECC-protected GDDR5 hp pavilion dv5t battery memory. They provide a theoretical computing capacity of up to 630 gigaflops in double precision. The cost is 2500-4000 dollars.

Nvidia has presented at the High-Performance Computing Conference SC09 in Portland, Oregon, its next generation of GPGPU computing boards. The models of the Tesla-20 Series are based on the GPU architecture "Fermi", also the upcoming DirectX 11 GPU GT300 is based.

The specially developed for parallel computing chips contain 512 cores and three billion transistors, about three times as many as among the most powerful GPUs hp pavilion dv6t battery, the Nvidia is currently offering. They support features such as ray tracing, 3D Cloud computing, video encoding, searching in databases, data analysis, computer-aided engineering and virus scans.

The Tesla cards c2050 and C2070 offer depending on the frequency according to the manufacturer, a theoretical computing power 520-630 billions of floating point operations per second (gigaflops) in double precision (Dual Precision, DP). Thus, they are about eight times faster than the most powerful Tesla C1060 board with GT200b chip, which comes only to 78 gigaflops hp pavilion dv7t battery DP.

By comparison, AMD's DirectX 11 graphics card ATI Radeon HP 5870 creates with its 2.1 billion transistors at 544 gigaflops of double precision. However, the map with a narrower memory interface is not designed for the HPC field, and supports different than the Nvidia card, no ECC error correction.

The c2050 is taking 3 GB ECC-protected to GDDR5 memory. The C2070 is double the amount available. The typical power consumption of the PCI-Express x16 card is Nvidia with 190 watts. High to the computing circuit boards consume 225 watts. They also have, in contrast to the previous Tesla cards have a DVI port, so no second graphics card is in use.

The Tesla c2050 is expected in the second quarter of 2010 are eligible for $ 2,500 on the lenovo thinkpad t400 battery market. The C2070 is expected in the third quarter and cost $ 4,000.

In addition, Nvidia has also announced pre-configured cluster solutions for data centers, which combine both Fermi GPUs in a rack mounting. The Tesla S2050 with 3 GB of memory appears four times in the second quarter for $ 13,000, the Tesla S2070 with 24 GB of GDDR5 RAM in the third quarter for $ 19,000.
