I read an article on wireless chargers recently which is used for charging mobiles. the mobile surface is made in such a way that there are a number of cells on the back surface,when this mobile is placed on the surface(used for charging) the surface senses the mobile and start charging. The interesting thing is we can place more then one mobile on the surface which will charge automatically.it is introduced by a company named Qphone(Ref. Electronics for you).

in this present scenario of explosion in the amount of traffic increase per day,the question regarding the longevity of the crude oil products basically,or the fossil fuels always lingers..
so the concept of hybrid cars come into the picture..
there have been many competitions held world wide in encouraging people into thinking of various innovative ideas in reducing the fuel consumption without compromising much in the part of performance..
Chevrolet Volt is the product manufactured by general motors..
it is one of the vehicles that have been commercially giving a decent performance in the market..
it works basically on a lithium ion battery that can cover over a distance of above 50 kms on average..
when the battery level drops..the car automatically shifts to a gasoline powered generator which runs the car..
the car is more effective in the cruising mode..
national geographic channel made a document on the manufacturing of this car in MEGA FACTORIES..
this car received many awards world wide for its green performance..i.e eco-friendly performance..
do read about it..

A field trial of LED light fittings in social housing says the new technology can deliver huge energy savings, reduce costs and makes residents feel safer.
The study, carried out by the Energy Saving Trust (EST), measured the performance of more than 4,250 LED light fittings installed at 35 sites.
The EST said it carried out the trial because an increasing number of LED lights were now commercially available.
It is predicted the technology could dominate the lighting market by 2015.
"We like to test things in-situ in order to understand their real performance rather than rely on manufacturers' claims," explained James Russill, EST's technical development manager.
But, he added: "We are at one of those rare times when there is a revolution, I think it is fair to say, within the lighting sector.
"LEDs promise to be the way forward for the whole sector, to be honest. There are so many benefits: they can be smaller, brighter; it is one of those rare technologies where the trial has shown it performs better than the lighting systems it is replacing but, at the same time, using less energy."
What is LED lighting?
Light-emitting diodes have been around for years.
Traditionally, they have been used as indicators on electrical devices, such as standby lights on TVs. This was because LEDs were only available in red, but recent advances means that other colours are now available, and the light emitted is much brighter.
White light (used for general lighting) using LEDs can be created via a number of techniques. One example is mixing red, green and blue LEDs.
It is suggested that LEDs can last for up to 100,000 hours, compared with the 1,000 hours of traditional incandescent light-bulbs and compact fluorescent lamps' (CFLs) 15,000 hours.
The technology is also much more energy efficient, using up to 90% less energy than incandescent bulbs.
The long lifespans and low energy use make LEDs economically attractive because even though the fittings cost more, the running and maintenance bills are lower.

Hei guys..
It's very pleasure to look at the researches of Large Hadron Collider. Now a days the scientific world is very hopeful since finding the presence of higgs boson from LHC last week. Actually higgs boson is considered as the hypothetical elementary particle that is responsible for the mass of an object. Some scientists also calls boson as a God particle. Since its existence can prove a lot of theories that exists today and will be helpful in developing new theories that may change the the phase of world. If we are able to findout the presence of higgs boson it will be considered as the invention of the century.http://en.wikipedia.org/wiki/Higgs_boson

Sony is creating electricity by leveraging an effect that allows termites to produce energy by eating wood.
At an exhibit in Tokyo, the company showed how cardboard can provide enough energy to power a fan.
Corrugated cardboard was used as a source for cellulose, whose glucose chain was broken up with enzymes to produce hydrogen ions and electrons. The electrons delivered electricity while the hydrogen ions reacted with oxygen, which resulted in water.
Don't get excited about a novel way to reuse old cardboard just yet: Sony notes that the power output is very low and a commercialization should not be expected anytime soon. Apparently the method is good enough to power digital music players, but it cannot recharge or replace common batteries.

Sierpinski triangle
The Sierpinski triangle (also with the original orthography Sierpiński), also called theSierpinski gasket or the Sierpinski Sieve, is a fractal and attractive fixed set named after the Polish mathematician Wacław Sierpiński who described it in 1915.Originally constructed as a curve, this is one of the basic examples of self-similar sets, i.e. it is a mathematically generated pattern that can be reproducible at any magnification or reduction.
the construction of the above geometric figure is given below
- Start with any triangle in a plane (any closed, bounded region in the plane will actually work). The canonical Sierpinski triangle uses an equilateral triangle with a base parallel to the horizontal axis (first image).
- Shrink the triangle to ½ height and ½ width, make three copies, and position the three shrunken triangles so that each triangle touches the two other triangles at a corner (image 2). Note the emergence of the central hole - because the three shrunken triangles can between them cover only 3/4 of the area of the original. (Holes are an important feature of Sierpinski's triangle.)
- Repeat step 2 with each of the smaller triangles (image 3 and so on).
If one takes Pascal's triangle with 2n rows and colors the even numbers white, and the odd numbers black, the result is an approximation to the Sierpinski triangle. More precisely, the limit as n approaches infinity of this parity-colored 2n-row Pascal triangle is the Sierpinski triangle.
The area of a Sierpinski triangle is zero (in Lebesgue measure). The area remaining after each iteration is clearly 3/4 of the area from the previous iteration, and an infinite number of iterations results in zero.
Google Go
The Go programming language is an open source project to make
programmers more productive. Go is expressive, concise, clean, and
efficient. Its concurrency mechanisms make it easy to write programs
that get the most out of multicore and networked machines, while its
novel type system enables flexible and modular program construction.
Go compiles quickly to machine code yet has the convenience of garbage
collection and the power of run-time reflection. It's a fast,
statically typed, compiled language that feels like a dynamically
typed, interpreted language.
