Electricity replaces gunpowder in a silent, smokeless, machine gun recently perfected for hostile against hostile air craft. With out betraying its location, this weapon is declared capable of firing 150 bullets or high-explosive shells a minute. Projectiles are hurled from its muzzle by a series of electromagnets spaced along the barrel, which start the missile moving and successively raise its velocity as they become energized.

A gun that uses moving electrons instead of messy chemicals to throw a slug has been a staple of speculative fiction since the days of Edison and Tesla and not only of fiction. Electrically operates projectile launchers variously known as gauss rifles, rail guns, and Mass drivers have both fascinated and frustrated military researchers the world over.

Actually, from the description given, it would be a coil gun, not a rail gun. A coil gun uses a series of electromagnets to propel the projectile down the barrel of the weapon. A rail gun uses a different effect called the Lorentz force (the force on a point charge due to electromagnetic fields).

The scrap of metal inside my magnet coil moved perceptibly each time, but that was about it. I guess my concerns about the danger of these home-built electromagnetic cannon were overblown. The wheel on the side is probably commutate spun manually or electrically to energize the coils sequentially to accelerate each projectile.

King Arms is proudly present you the first and only official licensed all you air soft players. Just by looking at it you guarantee you will fall in love with it first sight. You got to tell you that everything is so well-balanced, and the texture and finishing are just stunning. Everyone saw this 556 in person dropped their jaws and amazed by how well it is, simply because this is one of the best looking. This is a Full Metal equipped with polymer forearm and collapsible butt stock, and our 7mm bearing gearbox with special designed bolt carrier system allows the rifle to simulate the blow-back action of the real steel, at the same time, you can turn it into a normal AEG without the blow-back function within minutes, and vice versa.

Mobile phones in the third world

Connecting People’ might just be an ad slogan for a leading mobile manufacturer, but its sentiments hold more weight for millions of people living in third world countries who recently obtained mobile phones. Mobile phones have proliferated much more quickly and deeper into the third world than any other technology based product. Mobile phone technology may be ubiquitous in the developed world, but the effect that these hand held devices are having in the third world was not anticipated.

Mobile phones in the third world

The introduction of mobile phones in poor countries has been under different and extra ordinary circumstances compared to the bevy of retail options available in the developed world. Bangladesh, for example, got access to mobile phone technology as early as the late 90’s. Dhaka based ‘Grameen Bank’, known for taking micro lending to the rural population in Bangladesh, set up Grameen Telecommunications that provided low cost phone services in rural areas. Using the loans borrowed from Grameen Bank, village entrepreneurs, mainly females, purchased mobile phones which they than used to sell phone services to village customers who didn’t have access to their own phones.

Mobile phones in the third world

In the last few years, leading mobile manufacturers like Nokia, Motorola, Sony Ericsson, Samsung and LG electronics have set up mobile manufacturing units to meet the burgeoning consumer demand in India. Vodafone, one of the world’s leading mobile communications providers, launched a program called M-PESA in 2007, an innovative mobile payment service that enabled Kenyan customers to complete simple financial solutions by their mobile phone.

Mobile phones in the third world

A low level of income in the third world countries does not necessary make a consumer less demanding about the functionality and value of their purchases.

Taiwan based MediaTek played a key role in the development of Shanzhai phones as the company developed a circuit board that can integrate the functions of multiple chips, thus offering small start-up Chinese companies a platform to produce low-cost mobile phones.

Mobile phones in the third world

According to the UN report published in May 2009, six in ten people around the world have a cell phone subscription, which clearly indicates that mobile phones are the communication technology of choice, especially for people of third world countries.
