First Solar claims to have reduced the cost of manufacturing solar modules to $0.98 per watt, a record in making solar energy affordable.
Tempe, Ariz-based First Solar began production of modules in 2004 and reached the $0.98 mark in Q4 2008. From 2004 to the present, the company"s manufacturing capacity has grown 2,500% to more than 500 megawatts in 2008. Annual production capacity is predicted to double in 2009 to more than 1 gigawatt, the equivalent of an average-size nuclear plant, the company said. Through controlling costs while building volume, First Solar’s manufacturing costs have declined by more than two-thirds from the initial $3 per watt to less than $1 per watt.
You will be amazed by the graphics while playing Battlefield 3 Video Game.
The game looks real life. As id you are viewing a Movie.
If you have a Quad core CPU and a good graphics card you can play this game in very high quality.
Battlefield 3 will feature the maximalist combined arms battles that made the series popular across single-player, co-operative and multiplayer modes. It will reintroduce several elements absent from the Bad Company games, including fighter jets, the prone position and 64-player battles on PC. To accommodate the lower player count on consoles, the ground area will be limited for Xbox 360 and PS3, though fly space will remain the same. During an interview with GameInformer Magazine, EA stated that Commander Mode will most likely not be included, which was met with some criticism on the EA forum. Battlefield 3 uses a new type of character animation technology called ANT. ANT technology is used in EA Sports games such as FIFA, but will now be adapted to create a more realistic soldier, with the ability to transition into cover and turn their head before their body.
With a transmission distance of up to 2,000km without using electrical regenerators, Huawei" s 100G WDM prototype supports smooth upgrades from 10G/40G technologies. This innovation is expected to further promote and accelerate the commercial use of 100G WDM based solutions.
The current boom in broadband services has placed significant bandwidth demands and 100G WDM technology represents the next-generation in high-speed transport. Operators can transmit 10 times the traffic as compared to 10G WDM technology, the most widely deployed networking bandwidth. 100G WDM lays the foundation for telecom operators to deploy ultra-broadband services such as HDTV and multi-play in the future.
Researchers are developing a novel way to collect energy from the sun with a technology that could potentially cost pennies a yard, be imprinted on flexible materials and still draw energy after the sun has set. The new approach, which garnered two 2007 Nano50 awards, uses a special manufacturing process to stamp tiny square spirals of conducting metal onto a sheet of plastic. Each interlocking spiral "nanoantenna" is as wide as 1/25 the diameter of a human hair. Because of their size, the nanoantennas absorb energy in the infrared part of the spectrum, just outside the range of what is visible to the eye. The sun radiates a lot of infrared energy, some of which is soaked up by the earth and later released as radiation for hours after sunset. Nanoantennas can take in energy from both sunlight and the earth"s heat, with higher efficiency than conventional solar cells. "I think these antennas really have the potential to replace traditional solar panels," says physicist Steven Novack, who spoke about the technology in November at the National Nano Engineering Conference in Boston.
Taking antennas to the atomic level
The miniscule circuits absorb energy just like the antenna on your television or in your cell phone. All antennas work by resonance, the same self-reinforcing physical phenomenon that allows a high note to shatter glass. Radio and television antennas must be large because of the wavelength of energy they need to pick up. In theory, making antennas that can absorb electromagnetic radiation closer to what we can see is simple: just engineer a smaller antenna. But finding an efficient way to stamp out arrays of atom-scale spirals took a number of years. "It"s not that this concept is new," Novack says, "but the boom in nanotechnology is what has really made this possible." The INL team envisions the antennas might one day be produced like foil or plastic wrap on roll-to-roll machinery. So far, they have demonstrated the imprinting process with six-inch circular stamps, each holding more than 10 million antennas. It wasn"t immediately obvious the structures might be used for solar power. At first, the researchers considered pairing the antennas with conventional solar cells to make them more efficient. "Then we thought to start from scratch," Novack says. "We realized we could make the antennas into their own energy harvesters."
An economical alternative
Commercial solar panels usually transform less that 20 percent of the usable energy that strikes them into electricity. Each cell is made of silicon and doped with exotic elements to boost its efficiency. "The supply of processed silicon is lagging, and they only get more expensive," Novack says. He hopes solar nanoantennas will be a more efficient and sustainable alternative. The team estimates individual nanoantennas can absorb close to 80 percent of the available energy. The circuits themselves can be made of a number of different conducting metals, and the nanoantennas can be printed on thin, flexible materials like polyethylene, a plastic that"s commonly used in bags and plastic wrap. In fact, the team first printed antennas on plastic bags used to deliver the Wall Street Journal, because they had just the right thickness. By focusing on readily available materials and rapid manufacturing from inception, Novack says, the aim is to make nanoantenna arrays as cheap as inexpensive carpet.
Japan"s SpriteSat research satellite will use magnetoresistive random access memory (MRAM) to do the job of both flash memory and static random access memory (SRAM).
The MRAM can be programmed in 35 nanoseconds--five or six orders of magnitude faster than flash--and reprogrammed an unlimited number of times. Flash memory takes microseconds to program, milliseconds to erase, and can be reused only about 100,000 times.
IBM is working on an new type of memory that combines the pace and reliability of flash with the low cost and high capacity of hard drives.
In two papers published in Science, IBM fellow Stuart Parkin described the technology that he and a team of scientists are working on, called "racetrack" memory.
He believes the milestone could mean devices capable of storing far more data in the same amount of space than currently possible. Spin-offs include super-fast boot times, low cost and unprecedented stability and durability.
Called racetrack memory because data runs around a wire "track", it could eventually lead to solid state devices capable of storing 500,000 songs or 3500 movies - about 100 times more than possible today - with far lower cost and significantly less power consumption.
Scientists have long explored the possibility of storing information in magnetic materials by using "domain walls", the boundaries between magnetic regions in the material. The costly, complex and power-hungry process made the process incredibly difficult.
This results in a spin transfer torque on the domain wall, causing it to move.
The use of spin momentum transfer considerably simplifies the memory device since the current is passed directly across the domain wall without the need for any additional field generators.
