Most Expensive Accidents in History

Throughout history, humans have always been prone to accidents. Some, such as the exotic car crashes seen on this page, can be very expensive. But that’s trivial compared to the truly expensive accidents. My aim is to list the top 10 most expensive accidents in the history of the world as measured in dollars.

This includes property damage and expenses incurred related to the accident such as cleanup and industry losses. Many of these accidents involve casualties which obviously cannot be measured in dollar terms. Each life lost is priceless and is not factored into the equation.

Chernobyl

On April 26, 1986, the world witnessed the costliest accident in history. The Chernobyl disaster made 50% of the area of Ukraine in some way contaminated. The total costs has been estimated to be roughly $200 Billion.

Space Shuttle Columbia


The Space Shuttle Columbia was destroyed during re-entry over Texas on February 1, 2003. The total cost of the accident came out to $13 Billion according to NASA.


Prestige Oil Spill


On November 13, 2002, the Prestige oil tanker was carrying 77,000 tons of heavy fuel oil in Galicia, Spain. According to a report the total cleanup cost was $12 billion.

Challenger Explosion

The Space Shuttle Challenger was destroyed 73 seconds after takeoff due on January 28, 1986 due to a faulty O-ring. The cost of replacing the Space Shuttle 5.5 billion in today’s dollars.


Piper Alpha Oil Rig

This is world’s worst off-shore oil disaster. On July 6, 1988 due to a mistake by a technician Within 2 hours, the 300 foot platform was engulfed in flames. It eventually collapsed, killing 167 workers and resulting in $3.4 Billion in damages.

Exxon Valdez

The Exxon Valdez oil spill was not a large one in relation to the world’s biggest oil spills. On March 24, 1989, 10.8 million gallons of oil was spilled when the ship’s master. The cleanup cost Exxon $2.5 billion.

B-2 Bomber Crash

This B-2 stealth bomber crashed shortly after taking off from an air base in Guam on February 23, 2008. Investigators blamed distorted data in the flight control computers caused by moisture in the system.


Metro Link Crash


On September 12, 2008, 25 people were killed when a Metro link commuter train crashed head-on into a Union Pacific freight train in Los Angeles. Wrongful death lawsuits expected to cause $500 million in losses for Metro link.


Tanker Truck vs. Bridge


On August 26, 2004, a car collided with a tanker truck containing 32,000 liters of fuel on the Wiehltal Bridge in Germany. Temporary repairs cost $40 million and the cost to replace the bridge is estimated at $318 Million.


Titanic


The sinking of the Titanic is possibly the most famous accident in the world. But it barely makes our list of top 10 most expensive. On April 15, 1912, the Titanic sank on its maiden voyage . The ship cost $7 million to build ($150 million in today’s dollars).

Ten Most Powerful Computers in the World

Ever wondered which are the most powerful supercomputers of all time? Supercomputers which with their supersonic speed broke various computing barriers and also brought in revolution in varied fields like nuclear science, medicine, environment and weather. The computing power of these computers is way beyond your imagination.
So here I have compiled some of the most powerful computer in the world. I hope you will like it.

A new ADDITION >> China has recentrly taken top spot by China’s Tianhe-1A (Milky Way) to be the fast computer in the world. Details can be seen on BBCNews

Cray-1


Cray-1 was the world’s fastest machine that was installed at Los Alamos National Laboratory in 1976. Cray-1 boasted a speed of 160 million floating-point operations per second. The first model of the Cray-1 (Cray-1A) weighed 5.5 tons.

Cray-2


Launched in 1985, the machine held the title of the world’s fastest supercomputer between 1985-1989. Cray-2 was capable of 1.9 gigaflops peak performance. Cray-2 was predominantly developed for the United States Departments of Defense and Energy. Due to the use of liquid cooling, it was nicknamed `Bubbles’.

Connection Machine-5 (CM-5)


Launched in 1991, Connection Machine-5 (CM-5) held the crown for the world’s fastest supercomputer in 1992. The machine intended for artificial intelligence applications and symbolic processing found remarkable success in the field of computational science.
Fujitsu Numerical Wind Tunnel


Known as the Numerical Wind Tunnel, the machine was built by Fujitsu and Japan’s National Aerospace Laboratory. The machine was used to simulate wind turbulence on airplanes and in spacecraft as well as to forecast weather.

ASCI Red


The fastest computer from June 1997 to June 2000, ASCI Red was collaboration between Intel Corp and Sandia Labs. It was the first computer to break the teraflops barrier, which after the processor upgrade passed 2 teraflops.

ASCI White


ASCI White, an IBM system, replaced ASCI-Red as the fastest supercomputer in 2000. ASCI White held the spot for world’s fastest supercomputer for two years from 2000-2002. It was capable of computing 12.3 trillion operations per second.

The Earth Simulator


Built by NEC for the Japan Aerospace Exploration Agency, the Japan Atomic Energy Research Institute and the Japan Marina Science and Technology Center, the Earth Simulator (ES) was the fastest supercomputer in the world from 2002 to 2004.

Blue Gene/L


Currently the seventh fastest supercomputer in the world, IBM BlueGene/L held the title of world’s fastest supercomputer for four years from 2004 to 2008. The supercomputer is located at Lawrence Livermore National Laboratory’s. BlueGene/L (BGL) clocked 478.2 trillion floating operations per second.

IBM Roadrunner

IBM Roadrunner was crowned No. 1 in June 2008 after becoming the first supercomputer to break one petaflop/s. IBM’s Roadrunner managed 1.042 petaflops. The supercomputer is located at the Los Alamos National Laboratory.

Jaguar


The world’s fastest supercomputer according to TOP500 supercomputer list of 2009 is Cray XT5, also known as Jaguar. Jaguar bagged the No. 1 spot, beating IBM’s Roadrunner, who held the top crown from 2008 to 2009. It can perform more than 1 quadrillion calculations per second.
