Low and Cheap PCs

Personal Computer have changed the people life. And every person have a PC in their home in a normal family. And my opinion every one need a PC. But due the the huge amount of use of the energy due to the Computer in huge sector, the energy consumed is growing day by day. And there must be some solution to this problem. If the huge computer can be made to work in low power available then we can managed the energy saving and bring a revolution in the world.

After some research we found that green pc has been introduced by some people around the world and has been a great success. It has a saying that its energy costs reduced 60% of the current energy consumption. So a Low Power PC can be a great revolution for the people and countries.

Its not just about the power consumption, but they are also the cheapest found on market. If people are really concious about the energy and the money then, I suggest people surely should get a one. I have order a piece for myself, as every good things should be started from ownself.

Save energy, Save world – Go green.

Explosions caused by jet fuel and water sprinklers brought down Twin Towers on 9/11

article-2040657-0DC5696F00000578-647_468x310

A team of Norwegian scientists claimed that an explosive chemical reaction may have been responsible for collapse of the Twin Towers on 9/11.

They said molten aluminium from the aircraft flown by the terrorists combined with water from fire sprinklers and caused a powerful explosion.

Explanation? A team of Swedish scientists are providing a new theory into what caused the World Trade Center towers to collapse on 9/11Explanation? A team of Swedish scientists are providing a new theory into what caused the World Trade Center towers to collapse on 9/11

The 9/11 Commission – the official probe into the outrage – concluded that the Twin Towers fell on September 11, 2001 because the planes flown by terrorists caused ‘Total Progressive Collapse’ in both.

While the Norwegians do not dispute that general picture, they do say it does not explain the whole story.

That another theory could emerge a decade after 9/11 will stoke the many conspiracy theories around the collapse of the World Trade Center.

Over the years some have suggested it was the work of the Bush administration to justify the invasion of Iraq or even to allow traders to make a fortune by betting against the stock market.

Christian Simensen of the Norwegian Research Institute SINTEF, however, said that the terrorists’ planes were to blame.

His theory, presented at a technology conference in San Diego, is that when the planes went into the towers, they were trapped between floors which created a kiln-like effect.

This would have quickly pushed temperatures well past the melting point of their aluminium shell.

Collapse: Christian Simensen’s team suggests that when the planes hit the towers, they were trapped between floors and pushed temperatures far beyond the melting point of their aluminium shell

The melted aluminium would have run down to the lower floors where it mixed with water and caused temperatures to spike to 2,700 degrees and fire off explosive hydrogen.

These hydrogen blasts would have been enough to blow out sections of the building whilst the high temperatures would have weakened the steel supports.

Simensen said this was consistent with the official explanation of ‘Total Progressive Collapse’ in which the top floors of a Twin Towers fell in on themselves and put so much pressure on the floors below them that they collapsed too.

The bottom floors then hit the ground first, followed by the upper floors on top of them.

Simensen was unable, however, to shed any more light on what happened to the neighbouring 7 World Trade Center building that later on September 11, despite not being hit by a hijacked aeroplane.

The official version was that it was simply due to fire but ‘Truthers’ claim that no other steel building in history has ever fallen due to a blaze alone.

According to a recent piece in New York magazine: ‘In the truth-movement canon, “Building 7″ has assumed the Jack Ruby–Lee Harvey Oswald position in the overall 9/11 conspiracy claiming the entire episode was “an inside job,” planned and carried out by individuals connected to the Bush agenda.

‘Anthropomorphically speaking, Building 7 simply knew too much.’

Some 2,995 people including 67 Britons were killed when terrorists flew passenger jets into the Twin Towers on September 11, 2001.

A ceremony marking the 10th anniversary took place earlier this month, as well as the official opening of the 9/11 Memorial in Lower Manhattan.

These are the first pictures showing the progress being made on the construction at Ground Zero in New York.

Structural steel for the 1,776ft tower, which will be known as 1 World Trade Centre, has reached 200ft above street level, redevelopment officials said.

Taking shape: Construction on the new building began in 2006 and will include a museum and memorial to the 2,973 people killed on September 11, 2001

World Trade Centre

Progress: Construction on the new 1 World Trade Centre building at the Ground Zero site in New York has now reached 200ft

Workers are now installing 16 steel nodes on the 20th-floor of the tower which will serve as joints between the steel framing for the building’s podium and the steel for the rest of the tower.

Chris Ward, executive director of the Port Authority of New York and New Jersey – which owns the 16-acre trade centre site, said: ‘This progress is one more sign that the site is not a pit any more.

‘What people can’t see… is over 600,000 square feet of museum space being built below grade.’

Work is also proceeding elsewhere at the trade centre side as the Port Authority’s commissioners held their monthly meeting on World Trade Centre rebuilding.

The commissioners approved contracts for several projects, including a contract with New York-based DCM Erectors for installing a bronze memorial with the names of those who died at the twin towers on September 11, 2001.

Last year, authorities replaced the building’s former name of Freedom Tower. The 104-storey skyscraper is due to be completed in 2013 and will be one of the tallest buildings in the U.S.

Some 2,973 people, as well as 19 plane hijackers, were killed as terrorists flew airliners into the twin towers of the World Trade Centre, as well as the Pentagon.

9/11 10th anniversary: America remembers – Sunday 11 September 2011

ss-090911-memorial-02_ss_full

Services are held at Ground Zero, the Flight 93 memorial and at the Pentagon, as America pays tribute to those who lost their lives

 

8am ET: Good morning, and welcome to the Guardian’s live coverage of the 10th anniversary of 9/11. A series of events is taking place across New York to remember those who died in the terrorist attacks.

A service for victims’ families will be held at the site of the Twin Towers, where the 9/11 memorial will be dedicated to the 2,983 people who died in the US 10 years ago today. The memorial will open to the public on Monday, and features two pools, set in the locations of the towers. The names of those who died in the attack are inscribed into bronze parapets which surround the pools.

On Saturday a service was held in Shanksville, Pennsyvania, where United Airlines Flight 93 crashed as passengers and crew struggled with hijackers, while events have also been held at the Pentagon memorial, in Arlington, Virginia, where American Airlines Flight 77 crashed, killing 59 passengers and crew and 125 on the ground.

The 10-year hunt for Osama bin Laden came to an end in May, when US forces stormed his hideout in north-west Pakistan, although a CBS news poll this week showed that 67% of Americans feel no safer as a result of his death.

President Barack Obama will be at the New York ceremony, which begins at 8.35am. The president warned on Saturday that al-Qaida was likely to strike the US again, providing a stark reminder of the challenges the country continues to face, but for today the focus is firmly on the events of 10 years ago, as the US remembers the 9/11 victims and their families.

We’ll have the latest coverage from the tributes and services, with updates from our correspondents around New York.

8.10am ET: Karen McVeigh is out and about at a ceremony for some of the firefighters killed on 9/11:

I’ll be at the corner of 48th and 8th, home to the firefighters of 54 Engine, 4 Ladder, where a memorial service is being held this morning for those who were killed on September 11. Every firefighter who reported for duty that day died, 15 in all.

This is the firehouse known as the ‘Pride of Midtown’, which President Barack Obama chose to visit a few days after Osama Bin Laden was killed by US forces in Pakistan in May. The president called it a “symbolic site of the extraordinary sacrifice” made that day.

Today’s service is private for the families of those who died and the firefighters, but I am hoping to talk to some of them afterwards about what today means to them.

Karen has posted this picture from the ceremony. You can follow her coverage on Twitter.

8.15am ET: Paul Harris – @paulxharris – will be visiting some of New York’s landmarks this morning to discover what the means for ordinary city dwellers. Here’s his first dispatch:

On the streets of New York, away from the main ceremonies downtown, the heavy security presence of recent days is very much in evidence.

Even in the residential neighbourhood of the East Village there were police cars visibly patrolling the streets, or parked on street corners.

At Astor Place, police waited outside the subway station. In Times Square – itself the recent target of a failed car bomb attempt – the police presence is huge. Long lines of police cars snake down 42nd Strett, and there are mounted police on patrol. Bag searches are being carried out at the subway station.

However, the streets are also full of joggers, people taking their dogs for a walk and others out buying the morning newspapers (naturally full of 9/11 coverage). In Times Square the heavy police presence provided even more opportunities for tourists to pose with cops wearing their New York uniforms.

Some people who had clearly spent the night clubbing around Times Square and were only now heading home also took advantage. I saw one man wearing only a leopard skin coat and spandex shorts asking to pose with a police horse. The officer politely declined.

World Trade Center Bombing 1993

tanenbaum1640x304_0

On Friday, February 26, 1993, at 12:18 pm, a small cell of terrorists, with links to a local radical mosque and broader Islamist terror networks, detonated approximately 1,200 pounds of explosives in a rental van in the underground parking garage at the World Trade Center (WTC), below the Vista Hotel (3 WTC). The terrorists fled the area after setting the bomb to explode. The explosion created a five-story crater in the sub-grade levels of the towers and undermined the floor of the adjoining hotel.

The towers were relatively full when the bombing occurred, as wintery conditions may have kept many inside during the normal lunch hour. The explosion knocked out electrical power to the hotel, and significant areas within the North and South Towers (1 WTC and 2 WTC, respectively), affecting the operation of elevators, emergency communication, ventilation systems, and lighting. Emergency power generators were also damaged by the blast, and shut down after 20 minutes.

Most non-cable television stations in the greater New York area were blacked out, as the transmitters atop the North Tower lost power. Hundreds of WTC tenants and visitors were trapped in elevators, and thousands of others in 1 WTC and 2 WTC began to evacuate without guidance from first responders on the scene.

Within minutes, the North Tower lobby filled with thick black smoke. Elevator shafts and stairways were vertical conduits for the smoke, which quickly began to waft from the basement levels up both towers and the Vista Hotel. Some WTC tenants began a one-step-at-a-time evacuation down dark and smoky stairwells with improvised light sources such as cigarette lighters or mini-flashlights. Others were impeded by increasing smoke in the stairwells and forced to wait in conditions severe enough in some areas for tenants to break and hang out of windows. The complex’s telephone lines were working, and reports of those trapped in the buildings soon overloaded the City’s 9-1-1 system, preventing some calls from getting through. Over 100 visitors to the Observation Deck, many of whom were young children, were instructed to evacuate from the 107th Floor via the stairs. Another 72 schoolchildren and teachers were rescued from an elevator, after being trapped for hours.

 

 

 

 

 

 

 

 

 

The blast was initially thought to be a transformer explosion, but once the damage was seen, it was apparent that it was a bomb. Local, state, and federal agencies responded to the incident and contributed to what was then the largest coordinated rescue effort in New York City history. Within an hour, power for the entire WTC complex was shut down because of safety risks to firefighters working near water sources, leaving the buildings and its occupants in the dark.

Some Port Authority personnel with specialized knowledge of the building remained in the towers to assist with the evacuation and rescue. Firefighters climbed the stairs to lead people down, eventually reaching the towers’ top floors in some cases. NYPD helicopters transported rescue personnel to the roof, to assist in stairway evacuations of tenants on the upper floors. The general evacuation of WTC tenants down the stairs took more than four hours. Rescuers checked all 210 elevator cars – freeing trapped people from 45 of them – and searched each floor in the three buildings, more than eight million square feet of space. Later that evening, 28 people with medical conditions, including one woman in labor, were escorted to the roof by NYPD and airlifted to an Emergency Medical Services staging area, in controversial rappel and touch-down maneuvers.

The terrorist attack on the WTC killed six people: four members of the Port Authority’s World Trade Department, including a pregnant woman; a Windows on the World employee; and a visitor to the complex. Over a thousand people were injured, including 88 firefighters, 35 police officers, and one EMS worker. In total, approximately 50,000 people evacuated from the WTC complex. Many suffered psychological effects, some lasting to this day.

 

9/11 Related Terror

madrid2_0

This section examines terrorist attacks before and after September 11, 2001. Through the lens of 9/11, we will focus on terrorist assaults conceived, directed or modeled after the Al-Qaeda network and the cost of these attacks on individual lives and communities in the United States and around the world. The events of September 11, 2001 are part of an ongoing story that began well before that late summer morning when 19 hijackers seized control of four commercial airplanes and crashed them into the World Trade Center, the Pentagon, and a field in Pennsylvania. As we work to build a national institution dedicated to memorializing those killed in the attacks of 2001 and 1993, preserving the history, and helping visitors to understand its evolving significance, this series will provide information aimed at demonstrating how 9/11 exists within the context of a continuing global story, of which other related terrorist attacks are also a part.
