Light touch

Alright, this is freaking awesome! Your Star Trek or James Bond projection keyboard dream is turning into reality! This thing is called the Light Touch, an interactive projector that instantly transforms any flat surface into a touchscreen. The gadget adopts the Holographic Laser Projection (HLP) technology, which creates bright, high-quality video images in WVGA resolution. Integrated infrared sensors detect motion and turn the projected image into a 10.1-inch virtual touchscreen. Although the real deal doesn’t seem to be that perfect from what you think, but it’s still a good bump to push our dreams nearer to reality.

Geo Thermal Energy – A Renewable Energy Source

What is Geothermal Energy?

The word geothermal comes from the Greek words geo (Earth) and therme (heat). Geothermal energy is heat from within the Earth.Geothermal energy is generated in the Earth’s core, almost 4,000miles beneath the Earth’s surface. The double-layered core is made up of very hot magma (melted rock) surrounding a solid iron center.Very high temperatures are continuously produced inside the Earth by the slow decay of radioactive particles. This process is natural in all rocks. Surrounding the outer core is the mantle,which is about 1,800 miles thick and made of magma and rock. The outermost layer of the Earth, the land that forms the continents and ocean floors, is called the crust. The crust is three to five miles thick under the oceans and 15 to 35 miles thick on the continents.
The crust is not a solid piece, like the shell of an egg, but is broken into pieces called plates. Magma comes close to the Earth’s surface
near the edges of these plates. This is where volcanoes occur. The lava that erupts from volcanoes is partly magma. Deep underground,
the rocks and water absorb the heat from this magma. We can dig wells and pump the heated, underground water to the surface. People around the world use geothermal energy to heat their homes and to produce electricity.

Geothermal energy is called a renewable energy source because the water is replenished by rainfall and the heat is continuously produced deep within the Earth. We won’t run out of geothermal energy.

Finding Geothermal Energy

What are the characteristics of geothermal resources? Some visible features of geothermal energy are volcanoes, hot springs, geysers,
and fumaroles. But you cannot see most geothermal resources. They are deep underground. There may be no clues above ground that a geothermal reservoir is present below.
Geologists use different methods to find geothermal reservoirs. The only way to be sure there is a reservoir is to drill a well and test the
temperature deep underground. The most active geothermal resources are usually found along major plate boundaries where earthquakes and volcanoes are concentrated. Most of the geothermal activity in the world occurs in an area called the Ring of Fire. This area borders the Pacific Ocean.

Characteristics and Applications of Geothermal Energy

Geothermal energy is an enormous, underused heat and power resource that is clean (emits little or no greenhouse gases), reliable (average system availability of 95%), and homegrown (making us less dependent on foreign oil). Geothermal resources range from shallow ground to hot water and rock several miles below the Earth’s surface, and even farther down to the extremely hot molten rock called magma. Mile-or-more-deep wells can be drilled into underground reservoirs to tap steam and very hot water that can be brought to the surface for use in a variety of applications.

The general characteristics of geothermal energy that make it of significant importance for both electricity production and direct use include:

  •   Extensive global distribution; it is accessible to both developed and developing countries.
  • Environmentally friendly nature; it has low emission of sulphur, CO2 and other greenhouse gases.
  • Indigenous nature; it is independent of external supply and demand effects and fluctuations in exchange rates.
  • Independence of weather and season.
  • Contribution to the development of diversified power sources.


It has been estimated from geological, geochemical, shallow geophysical and shallow drilling data it is estimated that India has about 10,000 MWe of geothermal power potential that can be harnessed for various purposes. Rocks covered on the surface of India ranging in age from more than 4500 million years to the present day and distributed in different geographical units. The rocks comprise of Archean, Proterozoic, the marine and continental Palaeozoic, Mesozoic, Teritary, Quaternary etc., More than 300 hot spring locations have been identified by Geological survey of India (Thussu, 2000). The surface temperature of the hot springs ranges from 35 C to as much as 98 C. These hot springs have been grouped together and termed as different geothermal provinces based on their occurrence in specific geotectonic regions, geological and strutural regions such as occurrence in orogenic belt regions, structural grabens, deep fault zones, active volcanic regions etc., Different orogenic regions are – Himalayan geothermal province, Naga-Lushai geothermal province, Andaman-Nicobar Islands geothermal province and non-orogenic regions are – Cambay graben, Son-Narmada-Tapi graben, west coast, Damodar valley, Mahanadi valley, Godavari valley etc.

Lenovo launches first Ice Cream Sandwich TV

Lenovo is entering the TV business at this year’s CES, and it’s doing so with a splash: The company announced the world’s first TV set running Android 4.0, a.k.a. Ice Cream Sandwich. The device, dubbed the Lenovo K91 Smart TV, will initially be available only in China, but Lenovo is looking to launch it in other countries later this year.


Have you ever wondered what a virus sounds like? Or what noise a bacterium makes when it moves between hosts? If the answer is yes, you may soon get your chance to find out, thanks to the development of the world’s tiniest ear. The “nano-ear,” a microscopic particle of gold trapped by a laser beam, can detect sound a million times fainter than the threshold for human hearing. Researchers suggest the work could open up a whole new field of “acoustic microscopy,” in which organisms are studied using the sound they emit.

Most of us must have used a Microsoft product atleast once in a Lifetime….Many famous Microsoft products like WINDOWS OS, Microsoft office etc., According to the recent statistics more than 70% of people who use Computers have Windows Operating System in it and the remaining use other OS like LINUX and MAC….

This is the reason why Windows is much affected by Virus than any other OS, as the number of users are more all the hackers will try to target the larger population so we have around 100,000 known computer viruses only for Windows.

More of the complaints we get regarding Windows PC is about virus infection. You cannot use a Windows machine without antivirus or anti-malware. Even after having these programs installed there is still the risk of getting infected. Sometimes, viruses and malware even get past the best solutions. On the other hand, with Linux, you don’t need to worry at all about this. Your PC will hardly get infected with viruses with this operating system.

One of the key reasons LINUX and Mac are less prone to virus infection is that these systems require privileged access to install and run viruses. Malware rarely is able to gain root or privileged access to these devices and so it is more difficult to leverage system vulnerabilities. The idea that the dominance of Windows is a reason for its susceptibility is specious. LINUX install base covers everything from embedded processors to super computers. While Windows is definitely the dominant desktop OS, the increasing prevalence of embedded devices is rapidly making LINUX the most prevalent OS in the world. All without a major increase in susceptibility to malware.

Advantages of Linux


If you have used other operating systems, once you have made the switch to Linux, you will notice that Linux has an edge over Windows here. I can remember rebooting Windows many times over the years, because an application crashed, and I couldn’t continue working. Linux can crash also, but it is much harder to do. If an application crashes in Linux, it will usually not harm the kernel or other processes.

 Free Software

Most software can be obtained without cost for Linux. For example, one thing that has kept people from Linux is the lack of office software. That has changed with Open Office, and now you can edit documents and presentations from the popular Microsoft software. The conversion isn’t 100% perfect, but it has worked remarkably well in allowing me to correspond and use documents that people send me via e-mail or the web.

 Runs on old hardware

If you have an old 386 or 486 laying around collecting dust, you can use this to run Linux. I remember running Linux just fine on a Pentium 100 with a 1 GB disk drive, and 16 MB of memory. One use of an old machine like that could be a file server. Just go to your computer store, buy a large hard disk (as long as your old stuff can support it), and you can make a great storage server. With all the digital pictures and movies around today, this could be a great use for Linux. Look into using Samba, a server application for Linux that allows you to make your machine share the disk as a Windows share.


Linux has the advantage of the code being in the public domain. This can be a double-edged sword; while you can look at the code, and developers can fix holes rapidly, it also means hackers can find bad code. I have been very impressed with the security of Linux, and the programs that run on it. I think having the code out in the open, and the ability to fix things yourself if necessary is a big plus. Who likes to work blind? With some distributions, on installation the computer will ask you what levels of security you would like for your system. You can be very trusting, or you can be paranoid. Linux gives you this flexiblity.

The smart bullet

The XM25, currently under development for the U.S. military by Alliant Tech systems, allows soldiers to measure the distance to a target using a laser range finder, dials in exactly where the bullet should explode (over or past walls, the corner of buildings) at precise distances. At a cost of $30/round, the bullets are equipped with microchips capable of registering distance according to the number of times they’ve rotated.
