LOOKING TO LEAVES FOR SOLAR TECHNOLOGY ???

• A leaf is constantly building new photosynthetic reaction centers to replace those damaged by oxygen and sunlight.

 

• Scientists are experimenting with ways to apply the same principles to building solar energy cells.

 

• This new technology could yield a system that's highly efficient, can self-repair and works well under low light conditions.

Plants may hold the key to better solar technology

A new technique may one day lead to solar cells that bring themselves together like a molecular flash mob and repair damage they sustain during the rough business of turning light into electricity.

The research lays the groundwork for cheap, self-repairing solar cells with an indefinite lifetime, a team reports Sept. 5 in Nature Chemistry.

"It's a man-made version of what nature does," says nanocomposite expert Jaime Grunlan of Texas A&M University in College Station. "This really looks like ground-breaking seminal work; I've never seen anything remotely like it."

The sun's rays can be brutal, even for a leaf that's harvesting them. When photosynthesis is going full blast, a leaf is constantly building new photosynthetic reaction centers to replace those damaged by harsh oxygen species and other destructive molecules generated by intense ultraviolet light.

So rather than trying to make solar cells that are extremely durable, the team decided to take a literal leaf from nature's book and go the route of self-repair, says chemical engineer Michael Strano of MIT, who led the project. He and Stephen Sligar and Colin Wraight of the University of Illinois at Urbana-Champaign, along with other colleagues, designed a system where damaged parts could be easily replaced.

The researchers began with light-harvesting reaction centers from a purple bacterium. Then they added some proteins and lipids for structure, and carbon nanotubes to conduct the resulting electricity.

These ingredients were added to a water-filled dialysis bag -- the kind used to filter the blood of someone whose kidneys don't work -- which has a membrane that only small molecules can pass through. The soupy solution also contained sodium cholate, a surfactant to keep all the ingredients from sticking together.

When the team filtered the surfactant out of the mix, the ingredients self-assembled into a unit, capturing light and generating an electric current.

The spontaneous assembly occurs thanks to the chemical properties of the ingredients and their tendency to combine in the most energetically comfortable positions. The scaffolding protein wraps around the lipid, forming a little disc with the photosynthetic reaction center perched on top.  These discs line up along the carbon nanotube, which has pores that electrons from the reaction center can pass through.

Adding the sodium cholate back into the mix disassembles the complexes. But filtering it out again brings them right back together.

"The idea that it happens reversibly and at will is quite amazing," says Strano. "It approaches what happens in biology -- forming a huge amount of order with the flip of a switch. It's kind of like taking puzzle pieces and throwing them up in the air and them coming down assembled."

The complexes eventually lose power, but they are easily revived, says Strano. The research team disassembled the units and replenished the photosynthetic reaction centers. Four such replacements over the course of a week kept keeping the complexes humming along.

"This is very nice work -- the procedure they've got, the control they have over the system," says biochemist Mike Jones of the University of Bristol in England. "It's simple, it's very nice."

The units can't compete with silicon-based solar cells in use today. But silicon-based solar cells reached their current level of efficiency only after decades of research and development, says Jones. Similar investment in this new technology could yield a system that's highly efficient, can self-repair and works well under low light conditions, he says.

What's more, the main ingredients for these solar cells might one day be easily extracted from plant material, says Strano, perhaps even from garbage biomass. "We could turn waste into an organized product," he says.

from Australia's largest technology trade show: EO ultra mobile personal computer

Lia Timson rounds up the coolest gadgets at the latest technology trade show.

                                                                    Tech heads and early adopters must have had a field day at CeBIT, Australia's largest technology trade show. It wrapped up this week, clearing the way for the latest hardware and software to be embraced by consumers and businesses. Some of the gear is already available, other devices will arrive later this year. Much of it capitalises on the trend toward mobile work.

Among the stars of the show was the ultra-mobile personal computer (UMPC) - between a tablet PC and a personal digital assistant (PDA) - with full PC capabilities at half of the price of a tablet. The new $1650 EO from TabletKiosk is 50 per cent bigger than the average PDA, runs Windows XP and ditches Pocket PC applications in favour of full Windows software versions.

It's handier and lighter than a tablet or laptop and more useful than a PDA, primarily because of its 17cm touch screen. The UMPC will come with hard drives from 30GB to 160GB, and with memory up to 1GB. It is Wi-Fi and internet enabled, but does not have a mobile phone, although we are told one can be connected via Bluetooth.

Hugo Ortega, the principal of Tegatech Australia , distributors of the EO, says demand has already outstripped initial estimates, with 250 units sold in the first two hours of orders opening. It arrives in June.

"From what we've seen, there is demand for digital ink to take notes on the screen and have it transcribed to Word or other [program]," Ortega says. He says it will finally do away with paper notebooks carried around by students and note-taking professionals.

Samsung and Asus also have ultra-mobile PCs on the way soon.

Still on the portable stakes, a new credit card-size USB flash drive has arrived.

The compact Wallet Flash  has a double-sided USB port that sticks out and is small enough to fit snugly with other cards in your wallet.

Gilad Grinbaum, the director of G-Innovations , distributors of the Israeli-developed device, says it is waterproof, and starts from $30 for 128MB of storage.

If you're a mobile worker in tough and secret conditions, Panasonic's Toughbook CF-51 arrives in September. It is water and shock resistant and comes in a magnesium-alloy case. The 80GB hard drive is removable for security, and fingerprint and smart-card readers are optional. The series was designed to meet US military durability requirements.

is it car or fully featured of your gadget?: Mercedes-Benz F500 Concept Car

The F 500 Mind showcases the very latest technology

At the Tokyo Motor Show 2003, Mercedes-Benz presented the latest in a string of research vehicles which have attracted much interest and attention over the years and which provide fascinating insights into the automotive technology of tomorrow and beyond. Packaged as a modern four-door fastback saloon, the F 500 Mind mobile research lab showcases more than a dozen ideas for enhancing the safety, drive technology and comfort of future Mercedes passenger cars.

The DaimlerChrysler researchers will be using this vehicle to conduct the first practical tests of these innovative systems and pave the way for their commercialisation. The raft of innovations extends all the way from the night vision system with infrared laser headlamps to two-way doors and a programmable multivision display in the cockpit. Electronic accelerator and brake pedals, an interior pillar which provides structural rigidity and an ultrasound driver information system are further features being tested by Mercedes-Benz in the F 500 Mind.

For the powertrain, the DaimlerChrysler researchers have developed a high-performance diesel hybrid unit whose NEDC fuel consumption is up to 20 per cent lower than that of a comparable CDI engine. The state-of-the-art V8 diesel engine (184 kW/250 hp) from the S-Class has been combined with a powerful electric motor (50 kW) which is switched on and off by an electronic controller in response to traffic conditions and driving style. The electric motor can take over for example when moving off from rest, in stop-go conditions or in other situations where an internal combustion engine does not operate at optimal efficiency. When the driver demands more power, the V8 internal combustion engine cuts in to provide sharp acceleration. The 300 V battery for the electric motor is located under the passenger cell and is recharged during braking.

With a body length of 5092 millimetres and a wheelbase of 2965 mm, the F 500 Mind offers a significant gain in legroom in the rear compared with a conventional present-day saloon in this class. This was made possible by using innovative-design electronic accelerator and brake pedals which take the form of pressure-sensitive surfaces. Sensors in these “pedals” transmit the driver’s commands to the engine and SBCô brake system by means of electrical impulses. The technology takes up much less room than conventional mechanical pedals, increasing the length of the front footwell by 120 millimetres. The driver’s and front passenger’s seats can therefore be positioned further forward, so providing more space for the rear passengers. The steering, too, is controlled electronically.

Intelligent door-opening technology allows the doors to be opened in two different ways: either conventionally (both doors open forwards) or from the centre (centre-opening). In the latter mode, the B-pillar stump moves backwards with the rear door to provide a 1900 mm-wide opening for occupant entry and exit.

In the absence of full-size B-pillars, which would normally provide the all-important structural rigidity and side impact protection, the Stuttgart engineers came up with an innovative interior pillar which provides exemplary rigidity and typical Mercedes standards of occupant safety. The pillar is located in the middle of the vehicle towards the rear, and connects the reinforced floor pan to the roof structure. It also houses the air-conditioning ducts and interior lighting units.

The multivision display in the cockpit of the F 500 Mind forms the centrepiece of an innovative instrumentation and control system which offers the driver more flexible information delivery and at the same time reduces fatigue. The dials and displays in the instrument cluster are programmable and their images can be optically superposed or combined with the aid of a semitransparent mirror. In this way the driver can call up a wide range of information at the push of a button on the steering wheel. The information is always displayed directly in the driver’s field of vision where it can be seen easily and will not distract him. A further display, the central display unit, is situated above the centre console. It is linked to a touchpad whose surface is divided up in exactly the same way as the surface of the central display. By briefly touching it, the driver can control the navigation system, radio, air conditioning, telephone and other systems.

Further switches and keys in the vehicle are equipped with special sensors which can detect the driver’s approaching hand even at a distance of several centimetres. They then immediately call up the relevant function in the central display, for more convenient operation.

An advanced-design voice control system and an ultrasound-based driver information system take convenience even further. The ultrasound technology targets the sound at the driver so that only he or she can hear the information from the navigation system, the traffic news and other sound-based information sources, while the front passenger and rear passengers remain undisturbed.

In the dark or in poor visibility, the innovative night vision system projects its images onto the right-hand display. The night vision system consists of two infrared laser headlights on the front of the vehicle which “illuminate” the road with their invisible light over a range of up to 150 metres. The light reflected back from other vehicles, cyclists or pedestrians to a camera mounted on the front windscreen of the F 500 Mind is projected in black and white onto the multivision display. This allows the driver to spot hazards much earlier than in a vehicle operating on conventional dipped headlamps, which have a range of only about 40 metres. Thus Night Vision offers further opportunities for making night driving safer.

As a mobile research lab, the F 500 Mind is equipped with a special “laboratory bench” which folds out towards the rear. This allows a researcher sitting in the back of the vehicle to monitor and control the vehicle systems during testing on the proving grounds and to carry out measurements. For example the researchers are planning to use this fascinating vehicle for intensive user acceptance-testing of the innovative instrumentation and control system and for further practical testing of the diesel hybrid drive system and the Night Vision system.

man or robot:Cyberdyne is coming with the world latest technology of robot

A Japanese Company Cyberdyne 


is coming whit the world latest technology of robot. It is very interested to know that really it is very interesting device because it helps to disable people, we can know it the name of this device, HAL or Hybrid Assistive limb, it is a very unimaginative robotic suit for all robotic fans who are waiting for something special in this robotic field. This unimaginative robotic suit is very helpful for all disable and elderly people because it has the quality of reading brain signal and has far reaching benefits. This technology is the latest technology for the robotic field and it based on the computerized technology which has come with sensors device. In this robotic suit, reads brain signal and directs limb movement always comes through the skin which helps to disable and elderly people for moving around. It is very easy to use for them because it is worn as a belt around the waist and operated by a22 pound battery.

The Japanese company has come with this product of the cost of $1,500 for a monthly rental fee. Why we are saying so much about this interesting product because it really works so well how, first it has a sensor whish help for capture the brain signal and it goes thorough mechanical legs braces strapped to the thighs and knees.

latest Technology and new feature :cycle like Mercedes ?

How cool is this new Mercedes Concept Car?

It sure looks like an old-fashioned carriage, but according to Mercedes-Benz this will be the car for the future. Built with large spoked wheels, Mercedes-Benz has decided to go with traditional design features and latest technology. Good combination?

say very cool car , is powered by a hybrid drive system using an emission-free fuel cell. With a top speed of 15.5 miles an hour (25 km/h) you won´t be late for work. 

Taking a look inside this amazing car we will find carbon-fiber bucket seats with hand-stitched leather covers and a distinctively styled fiberglass front section that is inspired by Formula One racing cars. The car is controlled by a joystick instead of a regular steering wheel.

Google makes it official: Phone calls now in Gmail !

Gmail isn't just about e-mail anymore: it's also a phone.

Google launched the ability to make voice calls to any traditional phone number from a Gmail account Wednesday, which CNET had reported Tuesday was in testing. It's a blend of Gmail and Google Voice technology that allows users to dial numbers from their computers as well as receive incoming calls through one's Google Voice number.

Gmail users can link their Google Voice accounts with their Gmail accounts to have their in-boxes treated like just another line that will ring when people call their Google Voice numbers, and their Google Voice number will appear on the incoming call screen of those they are calling. A Google Voice account isn't required to use the service, but international calls will be funded through Google Voice accounts.

Calls to phone numbers in the U.S. and Canada will be free, and will cost 2 cents a minute to several other countries such as France and the U.K. The service should be rolling out to Gmail users in the U.S. on Wednesday, with international availability coming at an unspecified later date.

In a blog post announcing the feature, Google would only commit to offering free calls in the U.S. and Canada through the end of the year. Google's Craig Walker, product manager for real-time communications, said the company had no plans to raise rates beyond 2010, but it is still waiting to see if it will make enough margin on international calls to justify the free cost of U.S. and Canada calls. It will cost a little more to call mobile phones in countries outside the U.S., depending on the country.

Google Apps customers won't see this function just yet, no doubt disappointing some small-business customers looking to eliminate their phone bills. However, Google played it coy as far as plans for bringing out a business-friendly version of this technology, saying it wasn't ready as of yet but that it was interested in providing such a service.

The obvious target for such a service is Skype, the most well-known VoIP provider in the world with 124 million active users each month, according to data it released along with plans to raise money through an initial public offering. Google wouldn't confirm exactly how many Gmail users there are at present, only to say it was in the "hundreds of millions" according to Gmail product manager Todd Jackson.

However, Google has no plans to make this service available on mobile devices at the moment, which is an advantage for Skype and other VoIP companies. There are dozens of other mobile VoIP apps--including Skype--inside both Apple's App Store and the Android Market, although mobile VoIP is still a relatively new technology with performance problems from time to time. Google CEO Eric Schmidt has talked many times this year about the importance of developing applications for mobile devices, however, so it's not a stretch to assume Google is working toward making this feature available through either mobile browser or an Android application.

Google plans to promote the new service by installing Google Voice phone booths in various airports and universities around the U.S., where people will be able to step into the booths and make free phone calls.(bt cnet)

Japan's latest supermodel--a robot

The new Japanese humanoid robot HRP-4C displays a range of emotions (good luck discerning what they are) during a press conference in suburban Tokyo this week. Naturally, plenty of paparazzi were on hand.

She doesn't have the grace of a Cindy Crawford or Elle MacPherson (yet), but a few struts on the catwalk may help HRP-4C loosen up and hit her stride. The walking, talking girlbot will be getting practice soon, as she's set to make her catwalk debut at a Tokyo fashion show next week.

Scientists from Japan's National Institute of Advanced Industrial Science and Technology reportedly designed the 5-foot (ish), dark-haired creation to look like an average Japanese woman between the ages of 19 and 29. Unlike the average Japanese woman, however, HRP-4C has 30 motors in her body that allow her to walk and move its arms (somewhat loudly and awkwardly, if the video below is any indication) and 8 facial motors for blinking, smiling, and expressing emotions akin to anger and surprise.

According to the Associated Press, the robotic framework for the HRP-4C, sans face and other coverings, will sell for about $200,000, and the technology behind it will eventually be made public so people can come up their own moves for the bot.

The government-backed AIST says she's mostly being developed for the entertainment industry--for use in amusement parks, for example, or as an exercise teacher--and is not yet ready to help with daily chores. So unfortunately for those eager to hire HRP-4C as a home or office assistant, for now at least, her main job is to look pretty--or odd, depending on your perspective.
