This USB 2.0 flash drive comes with a 4 gigabyte large storage capacity and a design that may bring the thoughts to a certain golden shiny protocol droid from the Star Wars saga.

Future concept of mobile computing

How small and portable a computer can be? It’s almost impossible for us to avoid computer in our everyday life. Industrial designers show us glimpses of the future we are heading towards by their unusual concepts. Designer Elodie Delassus’s HOLO computer concept is hinting at the necessity of computers and need to make them easier to carry.

With the facts that holographic and sound vibrations are the future, he has re-invented the computer through his design. From the images and information available, we can figure out that this futuristic gadget is as small as a bracelet, which you can wear or put in pocket. The proposed material is flexible and resistance, so that safety issues could be dealt with efficiently. Further material needs to be shape retaining and non-conductive and non-allergic and most important, heat resistant. All these aspects have been considered by designer and he suggests promising bioplastic material to ensure all these aspects. The concept is very alluring, no doubt, but without technical specifications and functional information it’s just like a hypothesis that is waiting for proof in get materialized.

Portable computer in India

Yogesh Kumar Baghel’s MITRA PC is a cylinder-shaped portable computer. It was designed for rural areas in India in order to spread the importance of education, health and other social issues for the development of the country.
The term “mitra” means “friend,” and the MITRA PC is also an eco-friendly gadget that uses solar energy to store and use in case of emergency. The MITRA PC contains a built-in LED projector for convenient presentation, as well as a hand crank charging facility to generate power (rotating the crank 30 times provides 30 minutes of use).

Watch Concept

A wrist watch that has a see-through LCD screen made possible by a transparent polycarbonate material. The time is read out by digital digits, the digits appears to float in air when it is actually embedded in a clear polycarbionate material.

Clean Diesel: High MPG, Low CO2. Is it the Next ‘Big Thing?’

Today, diesels are being purchased in huge numbers by Europeans, with diesel models estimated to represent more than half of all new vehicles being sold there. Contrary to what you might think, these are not just small, entry level diesel vehicles, but also upscale diesel-driven rides like the BMW 7-Series, Jaguar S-Type, and Alfa Romeo 156.
This is in stark contrast to the diesel scene here in America, where nationwide diesel choices are more limited. However, a growing number of models have come to U.S. shores in recent years following nationally-mandated low-sulfur diesel fuel, which has made ‘clean’ diesel vehicles that meet stringent emissions standards possible.

Here, we have diesel pickups along with passenger vehicles like the Audi A3 and Q7; BMW 335 and X5; Mercedes-Benz E-Class, GL-Class, M-Class, and R-Class; and VW Jetta, Golf, and Touareg. Model choices have been expanding because of the growing demand for high fuel economy vehicles of all types … an area where diesel excels.

THE DIESEL DIFFERENCE Both gasoline and diesel powerplants are internal combustion engines, although they operate with significant differences. A gasoline engine runs on the Otto cycle, in which a vaporized mixture of gasoline and air is delivered to the combustion chamber, where it’s then compressed and ignited by a spark plug. In the Diesel cycle, air is compressed during the compression stroke and fuel is injected into hot, compressed air in the cylinder, spontaneously igniting the fuel. Because of this, the diesel is sometimes referred to as a compression ignition engine in contrast to a gasoline spark ignition engine.

There are also significant differences between diesel fuel and gasoline. For starters, diesel fuel requires less refining – and thus less energy to create – than gasoline and is similar to kerosene, jet fuel, and heating oil. Indeed, the military now uses a single fuel – JP-8 – in its jet engines, helicopter turbine engines, and diesel engines. Diesel fuel is heavier, oilier, and evaporates much more slowly than gasoline. Because of greater use of diesel fuel across the Atlantic, European refineries are more oriented toward refining crude oil into diesel rather than gasoline, the opposite of what occurs in North America. This preference is then reflected in how fuel is marketed.
A diesel engine achieves greater miles-per-gallon than an equivalent gasoline engine. With gasoline costing up to $6 a gallon in Europe, fuel economy has historically been more important to Europeans than Americans and a key factor in their preference for diesel power, even when diesels were still noisy and dirty. Diesel fuel has a higher energy density than gasoline, with a gallon of gas containing 85 to 87 percent of the BTUs (British Thermal Units) of a gallon of diesel fuel.

Diesel engines are also more efficient than their gasoline counterparts because more power is produced as a result of the higher compression of the air/fuel mixture. Today’s gasoline engines have compression ratios of about 10:1 to 11:1, while the compression ratios in diesels can be as high as 25:1. The higher the compression ratio, the more power generated.
The much higher compression ratio means diesel engines have to be heavier and more robust. This means they are more expensive to build, but the higher cost is offset by much longer lifetimes. For instance, we’ve seen Mercedes-Benz diesels with 350,000 or more miles on the odometer running great on the original engine. Because of higher component weight and high compression ratios, diesels operate at lower rpms, producing lots of low end torque but less horsepower.

‘NEW’ DIESEL = LOWER IMPACT Environmental concerns have long impacted America’s image of diesels. Many Americans still envision a diesel-powered vehicle belching out clouds of black smoke. That’s an image we’ve seen all too often from transit buses, big-rig trucks, and older diesel passenger cars over the years But if that’s your view of diesel vehicles now, then you have a lot to learn.
Computerized, turbocharged diesel engines equipped with emission control devices have pretty much taken care of this very obvious pollution problem. If you see a modern diesel smoking, it probably can to be attributed to poor maintenance.

Besides carbon monoxide, carbon dioxide, unburned hydrocarbons, and oxides of nitrogen emissions that are common to all internal combustion engines, diesel engine designers also have to contend with significant amounts of particulate matter, or soot. Innovations such as diesel traps or diesel particulate filters are now used to mitigate this by modern diesel vehicles. Because carbon dioxide emissions are directly related to the amount of fuel consumed, the fuel-efficient diesel engine does better than its gasoline counterpart when it comes to CO2 greenhouse gas emissions.
With the growing attention being devoted to C02 reductions these days, not to mention legislation that’s sure to drive the auto industry toward much higher efficiency and lower C02-emitting vehicles, diesel is sure to have a promising future.

Future Car Technology

Future car technology is now wide open. For instance, with peak oil looming and future shortages of fossil fuels imminent there has been much emphasis lately on cars that run on alternative fuels.

Ford Nucleon, top and GM Sequel, bottom

Future car technology will most likely involve a whole host of choices in regard to the fuel of choice.
Right now many automakers are gearing up for offering vehicles that are able to run on ethanol or other biofuels (such as biodiesel), which is the path of least resistance for the near future.
But, what about longer term? In the longer term, future car technology will most likely involve cars that run on hydrogen, electricity, air, nitrogen or even nuclear power. Some may see the nuclear-powered car as the most far-fetched of all of the ideas, but this is a mistake.
In fact, in 1958 the first nuclear automobile was pioneered and called the Ford Nucleon. The Ford Nucleon was a concept vehicle that was supposed to be powered by a small nuclear reactor at the rear of the vehicle fueled by radioactive material. No working prototypes were ever built, however.
So, this is not the say that nuclear-powered cars will never be part of the future. Car technology will most likely advance to the state will this will one day be a likely fuel of choice.
But, what is here now? Hydrogen, electricity, air and nitrogen cars all have had working prototypes built. In fact, in regard to electric vehicles, production models have also been built. But, the range of electric cars and their recharging rate have always been their downfall.
So, this is where hydrogen cars step in. Hydrogen cars at this writing can run from either internal combustion engines or fuel cells. Some of the current models of hydrogen cars like the GM Sequel have a proven driving range of over 300 miles in real world conditions. The BMW Hydrogen 7 has rolled out as a lease vehicle and is a dual fuel vehicle that can run off either liquid hydrogen or gasoline.
The Honda FCX was the first hydrogen car to be offered as a lease in 2004 and now the second lessee, actress Q'orianka Kilcher who played Pocahontas in the movie "The New World".
Electric cars also offer an option in regard to future car technology if the aforementioned issues may be resolved. Companies like Tesla, Zap and Phoenix Motorcars are making headway in developing these vehicles for the marketplace.
And, then there is the MDI air cars which may be going over big in Europe and India once the compressed air infrastructure is in place. The MDI air cars also have an onboard compressor that plugs into any outlet so this will help with vehicle acceptance.
So, far their has only been one nitrogen car prototype of note and this is the CooLN2Car developed by the University of North Texas. The car has stalled in development, however, due to lack of research funds.
Two other parts of advanced car technology to note are the future flying cars that will be taking flight over the next two or three years and smart cars that will also be seeing the highways and byways sometime in the future as well.

Dragunov Sniper Rifle

The Dragunov, specifically the Dragunov SVD, is one of the most popular sniper rifles in the world today. The Russian Dragunov SVD is considered, by collectors, to be one of the most highly prized trophies of all time.

So why is the Dragunov such a popular firearm? Why do so many people want one, and why is it so great?

Let's talk about the Dragunov, what it is, what it does, and the different types of Dragunov sniper rifles in production today.

What is a Dragunov sniper rifle? 

A Dragunov is a type of semi-automatic, gas-operated rifle manufactured originally in the Soviet Union. This is a rugged and reliable firearm which uses a powerful round, effective for up to 3200 feet (1000 meters). It has a chrome-lined barrel, for corrosion resistance. The Dragunov also has a slotted flash suppressor.

The Dragunov bears a number of similarities to the world-famous AK design including the large dust cover, iron sights and lever safety selector.

The Dragunov is classified as a "squad support weapon." It is meant to extend the range of the standard infantry squad mostly equipped with AK-47s or similar mid-range firearms. The Dragunov has a much longer range and greater accuracy than AK-type firearms. The shortcoming of the Dragunov is the smaller round capacity and the lack of a fully automatic rate of fire.

Dragunov Rifle Characteristics 

How do you know it's a Dragunov?

Dragunov rifles share a similar look. After a while you will find that you can distinguish a Dragunov from similar long-barreled rifles by its distinguishing features.

In no particular order, here are the common features of a Dragunov:

1. Long barrel

As befits a sniper rifle, most Dragunovs have a long barrel. Barrel lengths range from 23-24 inches. Note that there are some modern-production Dragunov carbines with shorter barrels but these are certainly not sniper rifles due to the loss of power and accuracy the short barrel causes.

2. Semi-automatic

All Dragunov rifles are semi-automatic. This means that each pull of the trigger fires a single shot.

Semi-automatic firearms are intrinsically less accurate than bolt-action firearms. However, most of the world's modern armed forces have transitioned to semi-automatic sniper rifles due to the rapidity of a follow-up second shot and ease of reloading.

3. Magazine-fed

Dragunovs are loaded by a magazine inserted into the bottom of the receiver. Magazines contain 5-10 rounds each.

4. Skeletonized stock

Nearly all Dragunov-style rifles have a skeletonized stock. This means that the stock (the wooden section held to the user's shoulder) is not a single solid unit. Instead, it has cavities or large missing sections in it.

Some Dragunov-type rifles have folding stocks. This is not a characteristic found on most sniper rifles. Fixed, or non-folding, type stocks are more rigid and are favored by snipers and other long-range shooters.

5. Scopes

Sniper rifles always have optical aiming devices (aka "scopes") mounted atop them. All Dragunov-style rifles come with an optical scope affixed to the receiver.

An interesting feature of Dragunov scope mounts is that they are set high above the receiver (the body of the rifle). This enables the user to peek below the scope and use the iron sights (mounted on the receiver and end of the barrel) to make shorter-range shots.

Dragunov scope reticle 

Here's what you see when aiming at your target!

The scope reticle ("reticle" means what you see when you look in the scope) is much more complicated than the traditional crosshairs. Additionally, the PSO-1 type scope often is either illuminated via tritium, illuminated via LED or has infrared or starlight capacity. This makes the sniper even deadlier in all settings!

Here's what it means:

The horizontal axis

The horizontal axis has a number of hash marks -- ten each on the left and right side. This helps the sniper to factor in wind drift when shooting at long ranges. Depending on range and wind speed, the shooter will aim to right or left of the actual target.

The vertical axis

The vertical axis has several ^-shaped marks. Each of these indicates the bullseye at a different range. The farther the range, the lower the ^ indicated on the sight.

The stuff on the lower-left corner

This diagonal line marked from 2-10 is the brilliant part of the Dragunov scope reticle. The intention here is that the marks indicate the average height of a man. If a target that you see in your scope stands on the bottom horizontal line and touches the "2" pip, then the target is 200 meters away. This "quick and dirty" range estimate is good up to 1000 meters (3290 feet, or 3/4 mile!).

Although this rangefinder technique is far less reliable than today's laser technology, it is also much more robust and reliable.

What makes a Dragunov a sniper rifle? 

A sniper rifle has three characteristics:

1. Range (long range)
2. Accuracy (maintains accuracy at long battlefield ranges)
3. Portability (one-person portable)

The Dragunov has a long range and is reasonably accurate (though not as accurate as bolt-action rifles with a similar range). It is easily portable by a single soldier.

The Dragunov is typically classified as a "designated marksman's weapon." That means that the best sharpshooter in a squad (6-12 soldiers) is equipped with this long-range weapon.

An actual sniper, whose sole responsibility is extremely long-range neutralization of enemy targets, typically is equipped with a more accurate weapon. Over half of the world's sniper rifles are bolt-action (which provide an intrinsic accuracy benefit over semi-automatic actions, at the cost of much slower follow-up shots).

Where can I get a Dragunov? 

My favorite online gun seller is Impact Guns. These sellers have some of the best selection and prices you'll find anywhere.

Impact Guns is highly recommended.
