ABB was selected by Power Grid Corporation of India Ltd

Will supply electricity to serve 90 million people.

ABB was selected by Power Grid Corporation of India Ltd. to deliver the world’s first multi-terminal UHVDC transmission link. The ±800 kV North-East Agra UHVDC link will have a record 8,000 MW converter capacity,a leading ×Indian government-owned power company that will deliver the remainder of the project worth more than $1.1 billion in total. The order will be booked on completion of financing requirements. including a 2,000 MW redundancy, and transmit clean hydroelectric power from ×India's northeast region to the city of Agra, a distance of 1,728 km.
The link comprises four terminals in three converter stations with a 33 percent continuous overload rating, enabling an 8,000 MW conversion- the largest HVDC transmission system ever built.
ABB and Bharat Heavy Electricals Ltd. (BHEL) have turnkey responsibility for ex*****on, including system engineering, design, supply and installation of three HVDC converter stations. Stage one is scheduled to be operational in 2014-2015, stage two in 2015-2016.
Northeast India has abundant untapped hydropower resources scattered over a large area, but load centers are hundreds or even thousands of kilometers away. Power must pass through the so called "chicken neck area," a very narrow patch of land (22 km width x 18 km of length) in the state of ×West Bengal having borders with ×Nepal on one side and ×Bangladesh on the other side.
One converter station will be in the northeastern state of ×Assam, and a second in the state of ×West Bengal in eastern India. The other end of the DC line will terminate at ×Agra, where two bipolar converters will be connected in parallel. The 800 kV equipment yard at ×Agra will for the first time be placed indoors.
This is the second ABB-built multi-terminal HVDC link. In 1990-1992, a large-scale three terminal transmission link was constructed in ×North America called the Québec - New England HVDC Transmission - the first of its kind in the world.
At full capacity, the North-East Agra UHVDC link will be able to supply enough electricity to serve 90 million people based on average national consumption. Ultrahigh voltage minimizes transmission losses and improves grid efficiency.
Power Rating: 6000MW (Multi terminal)
No. of Poles: Converter: 4 Line:2
AC voltages: 400kV
DC Voltage: ±800kV
Length of Overhead Line: 1728km
Main reason for choosing HVDC: Long distance, bulk power
Application: Connecting remote generation

GPS Tracking "Bullets" Could Help Reduce Car Chases

What's the Latest Development?

Police departments and state patrol agencies may soon have one more tool to help reduce the number of dangerous car chases on streets and highways: Officers in Iowa and Florida are currently testing Starchase, a compressed air gun that is installed under the grill of a police car and, at the press of a button, fires "bullets" that are actually GPS devices. Once one sticks to the fleeing vehicle, it delivers tracking coordinates to a computer or smartphone inside the police car, which will allow officers to slow down and, possibly, trick the suspect into slowing down as well.

What's the Big Idea?
Plenty of footage exists that shows the bad outcomes that result from car chases, so anything that can help make the streets safer should be welcome. Starchase still requires a good deal of testing before its official rollout: According to one news report, a demonstration in St. Petersburg resulted in only one of the four bullets sticking to the car. The other potential problem is the price tag: The system itself costs $5,000, and each bullet costs $500.

UN makes a battle plan to defend Earth from asteroids

Now here’s one straight out of the comic books: The United Nations has announced it’s going to start proactively searching for asteroids in Earth’s path — and taking measures to protect us from deadly collisions.

Asteroids — or as they’re known in the scientific community, “flying death rocks” — can be thrown off-course by a single hit from a spacecraft if the projectile is launched five to 10 years in advance.

This isn’t the last-minute USS Enterprise-style save you were probably looking for when you clicked that remarkably exciting headline, but a last-minute save would mean certain death for people unfortunate enough to be in the flying death rock’s path.

First steps, according to our besties at Scientific American, are the UN officially forming an International Asteroid Warning Group (note: will not include X-Men). This group will work with the existing Committee on Peaceful Uses of Outer Space.

Since no nation or space agency has claimed responsibility for keeping Earth safe from asteroids yet (thanks, America), private entities and astronomers will keep an eye out for potentially dangerous asteroids. Once these are identified, nations in a position to defend Earth will have to designate an agency, such as NASA, to coordinate countermeasures.
