During Summer we feel so bad with sweat and hot temperature but think of what these people who live in such a hot places do. Here comes the list of Top 10 Hottest places in the world
Rank
Place Country Temperature Extreme(F)1 Al'Aziziyah Libya 136.42 Greenland Ranch United States 1343 Ghudamis Libya 1314 Kebili Tunisia 1315 Timbouctou Mali 130.16 Araouane Mali 1307 Tirat Tavi Israel 1298 Ahwaz Iran 128.39 Agha Jari Iran 12810 Wadi Halfa Sudan 1271. The Retail DNA Test
Learning and sharing your genetic secrets are at the heart of 23andMe's controversial new service — a $399 saliva test that estimates your predisposition for more than 90 traits and conditions ranging from baldness to blindness. Although 23andMe isn't the only company selling DNA tests to the public, it does the best job of making them accessible and affordable. The 600,000 genetic markers that 23andMe identifies and interprets for each customer are "the digital manifestation of you," says Wojcicki (pronounced Wo-jis-key), 35, who majored in biology and was previously a health-care investor. "It's all this information beyond what you can see in the mirror."
2. The Tesla Roadster
Electric cars were always environmentally friendly, quiet, clean — but definitely not sexy. The Tesla Roadster has changed all that. A battery-powered sports car that sells for $100,000 and has a top speed of 125 m.p.h. (200 km/h), the Roadster has excited the clean-tech crowd since it was announced in 2003.
3. The Lunar Reconnaissance Orbiter
It may have been a long time since the U.S. built the world's best cars, but nobody can touch us when it comes to spacecraft. nasa is about to prove that again with the planned launch in February 2009 of the Lunar Reconnaissance Orbiter (lro). Our first unmanned moonship in 11 years, the lro will study the things lunar orbiters always study — gravity, temperature — but it will also look for signs of water ice, a vital resource for any future lunar base, and compile detailed 3-D lunar maps, including all six Apollo landing sites. Wingnuts, be warned: yes, we really went there
4. Hulu.com
When cable eventually dies, websites like Hulu will be held responsible. Unlike YouTube and other amateur-video-upload sites, Hulu is a hub for network TV shows and movies: Hulu offers shows from nbc, Fox, pbs and other channels, including free full episodes of SNL, The Daily Show, The Office and other hits the TiVo-less masses often miss, plus films like Ghostbusters, The Fifth Element and Lost in Translation. Created as a network-approved alternative to YouTube's grab bag, Hulu was at first roundly mocked as a ham-fisted corporate knockoff of the grass-roots glory that is YouTube. (It was also mocked for its weird name.) Instead it proved that suits can play in the Internet video space too and that studio content can coexist online with the user-generated kind. In doing so, it delivered the final blow that untethered TV from that box in your living room.
5. The Large Hadron Collider
Large Hadron Collider, the world's biggest particle accelerator, which went online in September, ran for 10 days and then had to shut down at least until next spring because of an overheated wire. The mammoth machine will send protons wheeling in opposite directions at nearly the speed of light, then smash them together at 6,000 times a second to try to answer such deep questions as why mass exists and whether the universe has extra dimensions. If it takes a few extra months to find out, so what?
6. The Global Seed Vault
Superman had it right: if you want to keep something safe, build a mountain fortress above the Arctic Circle. That's the thinking — more or less — behind the Svalbard Global Seed Vault. Almost every nation keeps collections of native seeds so local crops can be replanted in case of an agricultural disaster. The Global Seed Vault, opened this year on the far-northern Norwegian island of Spitsbergen, is a backup for the backups. It's badly needed — as many as half the seed banks in developing countries are at risk from natural disasters or general instability. The vault can hold up to 4.5 million samples, which will be kept dry at about 0°F (-18°C). Even if the facility loses power, the Arctic climate should keep the seeds viable for thousands of years. Let's just hope we still like corn then.
7. The Chevy Volt
No-emission electric motors — which began the automobile revolution — are the technology of tomorrow for cars. But today's batteries can't support the typical driving experience. Chevy's Volt is a nice compromise. The sedan has an electric motor with a battery that can provide up to 40 miles (about 65 km) of range on a single charge. A gas engine kicks in to recharge the battery while you're driving. Since nearly 80% of us drive less than 40 miles a day, that means that unlike the Prius, the Volt could get drivers off gas altogether. The best of both worlds lands by the end of 2010.
8. Bullets That Shoot Bullets
Think of the Army's new Active Protection System (APS) as Star Wars for soldiers, designed to protect them from rocket-propelled grenades and other short-range threats. Raytheon's APS will automatically detect an incoming round and then launch a missile to destroy it, all within a split second. If it works, future Army vehicles will be able to head into combat with less armor.
9. The Orbital Internet
In space, no one can hear you scream. But you will be able to send e-mail, thanks to a new protocol being developed for use there. It's hard to maintain a stable connection in orbit, so the interplanetary Internet will have to be especially tolerant of delays and disruptions. In September, a satellite used the new protocol to relay an image of the Cape of Good Hope back to Earth.
10. The World's Fastest Computer
On May 26, at 3:30 in the morning, a $133 million supercomputer nicknamed Roadrunner broke the long-sought-after petaflop barrier: 1 quadrillion calculations per second. Built by IBM for Los Alamos National Laboratory, Roadrunner will be used primarily to simulate the effects of aging on nuclear weapons.

1. Chernobyl
Cost:$200 Billion
On April 26, 1986, the world witnessed the costliest accident in history. The Chernobyl disaster has been called the biggest socio-economic catastrophe in peacetime history. 50% of the area of Ukraine is in some way contaminated. Over 200,000 people had to be evacuated and resettled while 1.7 million people were directly affected by the disaster. The death toll attributed to Chernobyl, including people who died from cancer years later, is estimated at 125,000. The total costs including cleanup, resettlement, and compensation to victims has been estimated to be roughly $200 Billion. The cost of a new steel shelter for the Chernobyl nuclear plant will cost $2 billion alone. The accident was officially attributed to power plant operators who violated plant procedures and were ignorant of the safety requirements needed.
2. Space Shuttle Columbia
cost:$13 Billion
The Space Shuttle Columbia was the first space worthy shuttle in NASA's orbital fleet. It was destroyed during re-entry over Texas on February 1, 2003 after a hole was punctured in one of the wings during launch 16 days earlier. The original cost of the shuttle was $2 Billion in 1978. That comes out to $6.3 Billion in today's dollars. $500 million was spent on the investigation, making it the costliest aircraft accident investigation in history. The search and recovery of debris cost $300 million.
In the end, the total cost of the accident (not including replacement of the shuttle) came out to $13 Billion according to the American Institute of Aeronautics and Astronautics.
3. Prestige Oil Spill
Cost:$12 Billion
On November 13, 2002, the Prestige oil tanker was carrying 77,000 tons of heavy fuel oil when one of its twelve tanks burst during a storm off Galicia, Spain. Fearing that the ship would sink, the captain called for help from Spanish rescue workers, expecting them to take the ship into harbour. However, pressure from local authorities forced the captain to steer the ship away from the coast. The captain tried to get help from the French and Portuguese authorities, but they too ordered the ship away from their shores. The storm eventually took its toll on the ship resulting in the tanker splitting in half and releasing 20 million gallons oil into the sea.
According to a report by the Pontevedra Economist Board, the total cleanup cost $12 billion.
4. Challenger Explosion
$5.5 Billion
The Space Shuttle Challenger was destroyed 73 seconds after takeoff due on January 28, 1986 due to a faulty O-ring. It failed to seal one of the joints, allowing pressurized gas to reach the outside. This in turn caused the external tank to dump its payload of liquid hydrogen causing a massive explosion. The cost of replacing the Space Shuttle was $2 billion in 1986 ($4.5 billion in today's dollars). The cost of investigation, problem correction, and replacement of lost equipment cost $450 million from 1986-1987 ($1 Billion in today's dollars).
5. Piper Alpha Oil Rig
$3.4 Billion
The world's worst off-shore oil disaster. At one time, it was the world's single largest oil producer, spewing out 317,000 barrels of oil per day. On July 6, 1988, as part of routine maintenance, technicians removed and checked safety valves which were essential in preventing dangerous build-up of liquid gas. There were 100 identical safety valves which were checked. Unfortunately, the technicians made a mistake and forgot to replace one of them. At 10 PM that same night, a technician pressed a start button for the liquid gas pumps and the world's most expensive oil rig accident was set in motion.
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.
6. Exxon Valdez
$2.5 Billion
The Exxon Valdez oil spill was not a large one in relation to the world's biggest oil spills, but it was a costly one due to the remote location of Prince William Sound (accessible only by helicopter and boat). On March 24, 1989, 10.8 million gallons of oil was spilled when the ship's master, Joseph Hazelwood, left the controls and the ship crashed into a Reef. The cleanup cost Exxon $2.5 billion.
7. B-2 Bomber Crash
$1.4 Billion
Here we have our first billion dollar accident (and we're only #7 on the list). 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. This resulted in the aircraft making a sudden nose-up move which made the B-2 stall and crash. This was 1 of only 21 ever built and was the most expensive aviation accident in history. Both pilots were able to eject to safety.
The crash was captured on video. It shows one B-2 Bomber successfully taking off followed by the B-2 Bomber which crashes. The crash starts at 2:00
8. MetroLink Crash
$500 Million
On September 12, 2008, in what was one of the worst train crashes in California history, 25 people were killed when a Metrolink commuter train crashed head-on into a Union Pacific freight train in Los Angeles. It is thought that the Metrolink train may have run through a red signal while the conductor was busy text messaging. Wrongful death lawsuits are expected to cause $500 million in losses for Metrolink.
9. Tanker Truck vs Bridge
$358 Million
On August 26, 2004, a car collided with a tanker truck containing 32,000 liters of fuel on the Wiehltal Bridge in Germany. The tanker crashed through the guardrail and fell 90 feet off the A4 Autobahn resulting in a huge explosion and fire which destroyed the load-bearing ability of the bridge. Temporary repairs cost $40 million and the cost to replace the bridge is estimated at $318 Million.
10. Titanic
$150 Million
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 and was considered to be the most luxurious ocean liner ever built. Over 1,500 people lost their lives when the ship ran into an iceberg and sunk in frigid waters. The ship cost $7 million to build ($150 million in today's dollars).
