Air Car Is Ready For the Road
2008-01-06 15:42:00
The world's first commercial compressed air-powered vehicle is will be running on the Indian roads very soon. The Air Car, developed by ex-Formula One engineer Guy Nègre and Tata Motors India has been under development for nearly fourteen years and could be become one of the biggest technological advances of this century. The fiberglass MiniC.A.T. runs on compressed air, and offers zero pollution and very low running costs.It is a simple, light urban car, with a tubular chassis that is glued not welded and a body of fibreglass. The heart of the electronic and communication system on the car is a computer offering an array of information reports that extends well beyond the speed of the vehicle, and is built to integrate with external systems and almost anything you could dream of, starting with voice recognition, internet connectivity, GSM telephone connectivity, a GPS guidance system, fleet management systems, emergency systems, and of course every form of digital entertainment....

Food Prices & Biofoolishness
2007-12-19 03:57:00
The price of food is on the rise all over the world .In US markets, the price of a bushel of wheat has gone over $10 for the first time. Soybeans are at a 34-year high. And corn is hitting new highs with every passing week.According to Simon Johnson, chief economist at the IMF, there are three factors responsible for the spike in prices.First, increased demand from emerging economies like India and China, where consumers are demanding more calories in their diet.Second, weather. Droughts have had an impact in some parts of the world.But third is the contentious relationship between food and fuel. Corn prices, according to the IMF, have doubled over the past two years. And in significant part, that is due to demand for the biofuel, ethanol, and the way in which ethanol policy is made in the United States.Hopes are running high that the second generation of biofuels may one day wean us off our reliance on petroleum, but until we're burning switch grass and wood waste, the dream has a...

Dumb cellphone user or a fleeceing service provider?
2007-12-13 20:10:00
A Canadian man has been shocked to receive a mobile phone bill for nearly $85,000.Piotr Staniaszek thought he could use his new phone as a modem for his computer under his $10 unlimited mobile browser plan from Bell Mobility.He downloaded high-definition movies and other large files unaware that this incurred massive extra charges. The trouble stems from the new phone he received when he renewed his mobile phone contract. The new model allows him to connect with his computer and download dataBell Mobility has since lowered the bill to $3,243, but Mr Staniaszek says he intends to fight the charges anyway and rightly so.Bell Mobility should have cut him off the moment he reached his limit on the bytes.The 22-year-old oil-field worker from Calgary said he thought a first bill for $65,000 in November was a mistake.When he spoke to Bell Mobility he was informed the bill had climbed to nearly $85,000 after more downloading. He said he normally paid about $150 a month for his phone and u...

Portable Computing Then and Now
2007-12-03 01:12:00
Released in April 1981 by the Osborne Computer Corporation, the Osborne 1 is considered to be the first true portable computer - it closes-up for protection, and has a carrying handle. It even has an optional battery pack, so it doesn't have to plugged into the 110VAC outlet for power.While quite revolutionary, the Osborne does have its limitations. For example, the screen is only 5" (diagonal) in size, and can't display more than 52 characters per line of text. To compensate, you can actually scroll the screen display back and forth with the cursor keys to show lines of text up to 128 characters wideThe two pockets beneath the floppy drives work great for floppy disk storage, although the Osborne modem also fits perfectly in the the left pocket and plugs into the front-mounted "modem" port.Osborne 1Introduced: April 1981Price: US $1,795Weight: 24.5 poundsCPU: Zilog Z80 @ 4.0 MHzRAM: 64K RAMDisplay: built-in 5" monitor53 X 24 textPorts: parallel / IEEE-488modem / serial portStorag...

Amazon's Kindle
2007-11-22 21:09:00
Amazon's Kindle e-book reader is the latest one entering E-book world of reading devices. So far reader interest has not picked up for these products, in spite of products like Sony PRS 505 Reader, Bookeen Cybook V3 and the iRex Iliad, which are available in the market for sometime. I for myself love Sony Reader.It looks like Kindle my not re-kindle buyer interest in portable reading devices. When you compare it with the features of Sony Reader, the new Amazon Kindle looks like a poor attempt to better this product. The Sony allows you to read virtually any format. It may not have the huge commercial titles selection that the Amazon gadget has, but you can read any PDF, TXT, RTF, DOCs, Blogs and RSS for free and right away. It also fails in looks, appeal and price when compared with Sony reader.It is on sale for $399 on Amazon.com and comes with some free reference books preloaded. You may also get subscriptions to news feeds from newspapers including the Wall Street Journal, Le Mo...
Challenges of finding Printer Cartridges
2007-11-18 14:39:00
With thousands of printer models around, it can be a big challenge to buy ink cartridges once you have run out of the in-box stuff. As is true with other electronics stuff, new models come out every 12 to 18 months and with that all the accessories for the old ones are gone from the shelves of electronics stores as well. I faced this problem first hand when I went to buy ink cartridge for my Epson Stylus CX3200. When the sale associate at Best Buy could not find it,he suggested that I should dump this printer and buy a new one, as it was a dinosaur of the printer world. While agreeing with his assessment,I did make some last ditch efforts to find any some options.And this effort lead me to Cartridge Finder and since then all my worries about getting ink cartridges is gone. It a very clean and easy to use website, where you can find ink cartridges for almost all the models at the click of the mouse. Folks instead of wasting hours at the electronic stores try this out.

PayPerPost--Blogger meets Advertisers
2007-11-01 23:21:00
Over the years, Blogging has established itself as respected and accepted way for getting independent and unbiased opinion on all kind of issues, product, current affairs and what not. And all this have not escaped the eyes of advertisers and they are always on the look out for getting some attention from the Blogger s and that is were payperpost comes in the picture. payperpost is unique and I believe the only website which is acting as match maker for such opportunities.I came across payperpost soon after I started my blog and since then I have been writing some sponsored blog every now and then. Even though my blog is very specialized, I do find a few opportunities occasionally and little bit of revenue from such sponsored post gives you a good incentive to take look at some of the products and services.I just like everything about payperpost, right from the home page to registration to take opportunity to write a post and to getting paid for the post.

Greenpeace warning about iPhone
2007-10-16 16:15:00
According to a statement on Greenpeace 's Web site,"An independent scientific laboratory tested 18 internal and external components of the iPhone and confirmed the presence of brominated compounds in half the samples, including in the phone's antenna, in which they made up 10% of the total weight of the flexible circuit board.A mixture of toxic phthalates was found to make up 1.5% of the plastic (PVC) coating of the headphone cables.” As per Greenpeace Research Laboratories, two of the phthalate plasticisers are classed in Europe as “toxic to reproduction, Category 2” because they can interfere with sexual reproduction in mammals.They have called on Apple to eliminate the use of these chemicals in its products. And also the Greenpeace testers found that phone’s battery was glued and soldered in place. “This hinders battery replacement and makes separation for recycling, or appropriate disposal, more difficult, and therefore adds to the burden of electronic waste.”Now is...

Giant Magneto Resistance--- Wins Physics Noble Prize for 2007
2007-10-09 22:52:00
The 2007 Nobel Prize in physics has been awarded to Albert Fert and Peter Grunberg for simultaneously and independently discovering Giant magneto resistance. This property has allowed the explosion of disk-space growth and is cited as being one of the first nano-technology breakthroughs.Magneto resistance is the property of a material to change the value of its electrical resistance when an external magnetic field is applied to it. The effect was first discovered by William Thomson in 1856.The magnetoresistance of conventional materials is quite small; but materials with large magnetoresistance have been synthesized now. Depending on the magnitude, it is called either as Giant magnetoresistance(GMR) or Colossal magnetoresistance(CMR). Magnetoresistance has aroused great interest recently because of possible application in devices such as read/write heads in computer discs and in sensors.Colossal Magnetoresistance has been predominantly discovered in manganese-based perovskite oxides....

What is A2DP,AVCTP,AVDTP,AVRCP?
2007-10-05 20:33:00
In order to use Bluetooth wireless technology, a device must be able to interpret certain Bluetooth profiles. The profiles define the possible applications. Bluetooth profiles are general behaviors through which Bluetooth enabled devices communicate with other devices. Bluetooth technology defines a wide range of profiles that describe many different types of use cases. A2DP,AVCTP,AVDTP and AVRCP are Bluetooth protocol stack used by the profile.Advanced Audio Distribution Profile (A2DP) ;A2DP describes how stereo quality audio can be streamed from a media source to a sink. The profile defines two roles of an audio source and sink. A typical usage scenario can be considered as the “walkman” class of media player. The audio source would be the music player and the audio sink is the wireless headset. A2DP defines the protocols and procedures that realize distribution of audio content of high-quality in mono or stereo on ACL channels. The term “advanced audio”, therefore, should...

WAP Over Bluetooth Profile (WAP)
2007-10-01 17:27:00
WAP defines how the wireless application protocol suite can run over a Bluetooth wireless technology link. A typical configuration is a mobile phone connecting to a public kiosk over a Bluetooth technology link and using WAP to browse for information. WAP works across a variety of WAN technologies bringing the Internet to mobile devices. Bluetooth technology can be used to provide a bearer for transporting data between the WAP client and an adjacent WAP server. The ad hoc networking capabilities offered by Bluetooth technology gives a WAP client unique possibilities regarding mobility compared with other WAP bearers. The traditional form of WAP communications involves a client device that communicates with a server/proxy device using the WAP protocols. WAP technology supports server push. Used over Bluetooth technology, this protocol offers many possibilities for distributing information to handheld devices on location basis.

The reality of Cyberwars reached a new level in the wake of sustained denial-of service attack on the Estonian government web sites which were targeted for several weeks in April and May this year. A global botnet of compromised home computers was used to create and direct the packet flood attack and hackers also defaced key government web sites.Malicious activity will continue to be on the rises as we move away to more and more towards e-commerce. This is going to poise a treat to the countries and business a like.According to Symamtec's last Internet Security Threat Report on malicious cyber activity in different countries the United States accounted for 31% of malicious activity, China came in second with 10%,Germany was in third place with 7%, France (4%) and United Kingdom 4% completed the top five.Taking the amount of a country's malicious activity and dividing by the number of that country's Internet users, Symantec found that Israel has the most per capita malicious Inter...

GOCE- Another Gravity Probe
2007-07-28 14:57:00
In my earlier post we talked about NASA's Gravity Probe B, not to be left behind European Space Agency (ESA) is getting ready to launch their gravity probe-- The Gravity field and steady-state Ocean Circulation Explorer (GOCE) scheduled for launch in spring 2008.GOCE is dedicated to measuring the Earth’s gravity field and modelling the geoid with extremely high accuracy and spatial resolution.GOCE data will also be used for probing hazardous volcanic regions and bringing new insight into ocean behaviour. By combining the gravity data with information about sea-surface height gathered by other spacecraft, scientists will be able to track the direction and speed of ocean currents.What will it do?Most of us know that the acceleration due to gravity on Earth's surface is 9.8m per second squared - but, in truth, this figure varies around the planet depending on the nature of the material underneath the earth's surface.The figure varies from 9.78 (minimum) at the equator to 9.83 (max...

GRAVITY PROBE B & EINSTEIN'S PREDICTIONS ABOUT GRAVITY
2007-07-08 16:34:00
While theoretical physicist have come up with new theories to explain the phenomena of gravity, scientists have not given up on Albert Einstein's general theory of relativity, or theory of gravitation.Everybody knows about the Albert Einstein's well established theory of relativity we now call special relativity which leads to E = mc2 (energy equals mass times the speed of light squared), and is a very well established experimentally.Einstein's also established the general theory of relativity to explain the gravitation and unlike special relativity, surprisingly few tests have been made quantitatively of the results of this theory. But that was until NASA launched Gravity Probe B in April 2004.The data collected by Gravity Probe B during 17 months orbiting around the Earth is putting general theory of relativity to the test.Since October 2005, scientists have conducted painstaking data analysis and validation.The preliminary results were announced in April 2007 for the geodetic ...
