Global Positioning System

GPS, or Global Positioning System, is a technology that is capable of pinpointing your exact location anywhere on the planet. Of course, it's not always that simple and there's more to it than being a way for guys to avoid asking for directions. We’re sure most of you techies must be well-versed with GPS since it’s become increasingly popular in India, but we thought it wouldn't be out of place to offer some basic information about it and what it can (or can't) do for you.

Integration of GPS with mobile phones didn't take long. It's still nascent in India, but quickly making progress. Maps offered have to be approved by the Government of India, and even then there's no guarantee that it will work, given the enthusiasm with which we keeping digging up our streets... think there's oil beneath, or gold?

How it Works
GPS works on satellite imaging, so you will need to be out in the open (it won’t work indoors). GPS is operated by the US Department of Defense, but other countries are beginning to build their own infrastructure. GPS is especially useful in the aviation and automotive industry, but we’re concerned with handheld GPS systems available in mobile phones such as asusP535 nokia 66and 6120.

If you're the outdoorsy sort who drives around, or do a lot of traveling on the job, it’s good to know where you are and what you’re getting into right? The Nokia Navigator, for instance, provides that can be downloaded before you embark on your tour. Obviously, this will be less sophisticated than the GPS technology used by fleet management companies, but then it comes in a smaller package and you don’t need an additional device.

Finding Your Way
You can do a lot with a mobile handset loaded with an inbuilt GPS system. For starters, you can simply plot a route from your location to any place on the map. The drawback is that the place you wish to visit should be on the map as a POI (Point of Interest), or be a location you have saved previously.

Of course, GPS systems need to be fleshed out before use, and for basic navigation purposes your mobile GPS can only get your so far. The system takes no cognizance of roads in repair, so what may seem like a perfectly normal routing could go awry.

To top it all, we have unorganized and incoherent naming standards, with most roads not having proper names. For example, if you’re a Mumbaikar you’ll probably know where Hill Road in Bandra is, but on a GPS map you may not find it all. Besides, there’s more than one way you can reach your destination from anywhere in a city.

If you're on foot you can take the shortest route indicated. If traveling by vehicle you can do the same, but this might not take into account how big or small (or congested) the roads are. Some GPS-enabled handsets have an 'easiest route' option, which plots the most sensible route to your destination keeping in mind only the main roads etc.

Camcorder reviews

If you are looking for a latest camcorder, then you are at the best place to find the best reviews on the camcorders in the world, the latest, the newest and the best on the online world.

This cool website called ExpoTV, here you can watch the reviews on the all latest camcorder. The reviews on the camcorders that are featured on their website consist of the big brand players like Sony, Panasonic and Canon. One need feature is that they have lots of different reviews on the same product, which means, you can have more then one person's opinion on the same product. Not bad. Love this feature. One more thing I love is that the reviews are in video form which means you do not have to read the long written reviews of the camcorder.

Now, before going through various camcorders i am giving you about the leading manufactures. Mainly there are four main manufacturer companies are: Sony, Panasonic, Canon and JVC. Canon and Sony dominates the lower price models, Panasonic dominates the 3 CCD world and JVC dominates with a lot of Hard Drive cameras.

Sony Camcorder: These high definition camcorder records to tape in the HDV format, which continues be the format of choice for those who prize video quality over the convenience of flash media, HDD, and DVD.

Panasonic Camcorder:Panasonic positioned itself firmly in the AVCHD camp with the announcement of the AG-HMC150.The new AG-HMC150 records solely to SD/SDHC cards in the AVCHD format at an unspecified maximum bit rate.

The JVC Camcorders and Canon Camcorder are other two choices as these companies had large variety of camcorders.

So Now I can say about this website is that it is a great website. Do check it out now for some latest reviews on ExpoTV.

Paint to generate electricity

A lick of solar-power paint could see the roofs and walls of warehouses and other buildings generate electricity from the sun, if research by UK researchers pays off.

The scientists are developing a way to paint solar cells onto the steel sheets commonly used to clad large buildings. Steel sheets are painted rapidly in steel mills by passing them through rollers.

A consortium led by Swansea University, UK, hopes to use that process to cover steel sheets with a photovoltaic paint at up to 40 square metres per minute.




The paint will be based on dye-sensitised solar cells.

Instead of absorbing sunlight using silicon like conventional solar panels, they use dye molecules attached to particles of the titanium dioxide pigment used in paints.

While less efficient than conventional cells, dye-based cells do not require expensive silicon, and can be applied as a liquid paste.
