There is a deafening, unearthly howl as if a jumbo jet was firing up its engines in London's Hp Pavilion ZT1100 battery Albert Hall. On the screen in the control room a ghostly pinkish glow whips round the edges of the inside of the nuclear reactor. At its core it is 10 times hotter than the centre of the sun.
This, according to some physicists, is the solution to the Hp laptop battery energy crisis a future with cheap, reliable, safe and nearly waste-free power. Today, after years of false starts and political wrangling dating from the Cold War, they will get their chance to make that dream a reality.
A US$14 billion project, called Iter, to build a prototype nuclear fusion reactor will be signed off in Brussels by the EU, Japan, China, South Korea, India and the United States.
The prospect of virtually limitless energy is not merely science fiction. The haunting, screaming growl of matter being smashed together at unimaginably laptop battery high speed is a daily occurrence at Jet in Oxfordshire, Southern England, an existing experimental fusion reactor. Jet is by far the biggest of the world's 28 fusion reactors. It is the work of scientists here that has paved the way for the much bigger Iter, which, once the project is ratified in December, will be built in Cadarache in southern France.
Its advocates say nuclear fusion is the most promising long-term solution to the energy crisis, offering the possibility of abundant power from cheap fuel with no greenhouse gases and low levels of radioactive waste. But critics say the government is gambling huge sums of money 44% of the UK's research and development budget for energy on a long shot with no guarantee of ever producing useful energy.
Last week British Prime Minister Tony Blair backed conventional nuclear Hp Omnibook XT1000 battery power, saying in a speech to business leaders that not replacing Britain's ageing nuclear power stations would be "a serious dereliction of our duty to the future of this country."
He argued that only nuclear energy could prevent a huge hike in CO2 emissions once the current nuclear stations were decommissioned.
But while the debate over the future of conventional nuclear power continues, many physicists argue that fusion is the future. "Fusion works it powers the sun and stars," said Sir Chris Llewellyn Smith, head of the UK Atomic Energy Authority. "In the second part of the century I'm optimistic it will indeed be a major part of the world energy portfolio."
Unlike nuclear fission, which tears atomic nuclei apart to Hp Omnibook XT1500 battery release energy, fusion involves squeezing the nuclei of two hydrogen atoms together. This process releases a helium nucleus and a neutron plus huge quantities of energy.
The hydrogen fuel is part heavy hydrogen or deuterium, which can be easily extracted from water, and part super-heavy hydrogen or tritium, which can be made from lithium, a reasonably abundant metal.
The energy produced is truly colossal. The lithium in just one laptop battery and the heavy hydrogen from half a bath of water could provide enough energy for the average European for 30 years.
One of fusion's big advantages over fission is safety. Firstly, there is no chance of a runaway meltdown as happened at Chernobyl.
If you stop applying the fuel or switch off the magnetic jacket that keeps the fuel in Hp F2019 battery the reactor, the reaction just stops.
"It is very difficult to keep it running. It is like keeping honey on the back of a spoon," said Mathias Brix, a physicist at Jet. Also, the quantities of fuel involved are much smaller than in fission reactors. Jet contains less than a gram of fuel, while Chernobyl had 250 tons. Lastly, the fuel and waste from the reactor is much less radioactive.
But although physicists think they understand fusion, harnessing it has proved extremely difficult. Research first began in the 1950s with claims that fusion would provide reliable power by the end of the century but even now scientists admit that a commercial application is at least 40 years away.
The problem is getting two Hp F2019A battery nuclei close enough to fuse and then controlling the reaction. This means putting in huge amounts of energy at the start to convert less than a gram of the fusion fuel into a super-hot gas or plasma. Hydrogen nuclei flying around at high speed in the plasma can then come close enough together to fuse.

weary soles

Sun Hao lounges on a sofa inside the Beijing Jianqiao Blind Massage Center and waits for her feet to be Hp laptop battery massaged. The 24-year-old bank clerk has been suffering from a stiff neck and backache and is willing to try anything to relieve the pain.
"I sit in the office all day long, facing the laptop Hp F4098A battery and, except for lunch, I rarely stand up or walk around," she says. "I am not as energetic as I was when I was a student and my health has suffered. So I came here to see if reflexology works."
But how does a simple foot massage, a traditional Chinese medicine (TCM) practice spanning back 5,000 years, cure the back and neck of a modern day office worker?
Wu Lianjun, a masseur in Beijing Jianqiao Blind Massage Center, says the soles of the feet provide an insight into the entire human body. "When both feet are put together, they form a reflective map of the human body," he says.
"The two toes represent the head, the upside of the foot represents the chest, the middle part of the foot reflects Hp F4809A battery the abdomen and the lower part of the sole, the pelvis."
"Through stimulating certain reflex zones on the feet, the corresponding organs will function better and some discomforts may be relieved."
Reflexology, or foot massage, originates from Yellow Emperor's Canon of Medicine and has a long recorded history of useful application.
Sima Qian's Shi Ji (Historical Records), written around 200 BC, referred to a distinguished foot doctor named Yu Fu, who practiced his massage technique during the era of the legendary Yellow Emperor, thousands of years before this book was written.
Luo Mi's book Lu Shi, which was Hp F4812A battery written in the Song Dynasty (960-1279) and records Chinese history, geography and culture, also mentions reflexology as a way to stimulate painful points on the foot in order to alleviate discomfort and even cure disease.
TCM practitioners believe the feet play the part of "the second heart" in the flow of blood. The feet, they say, are linked to organs by meridians, which interweave through a large network of paths that circulate qi (energy) and blood.
The network connects all parts of the body, making it an intercommunicating whole. That is known as reflexology.
Liu Jie, another reflexology practitioner, says qi and blood circulation is a central theme. "The feet are located in the lowest part of the human Hp 319411-001 battery body, far away from the heart, and are prone to slow qi and blood circulation," he says. "By applying controlled pressure on certain areas on the foot, reflexology serves as a catalyst to dredge vessels and smooth the qi and blood circulation so as to promote the functioning of organs, such as the kidney, bladder and lung. It therefore helps eliminate toxins, enhancing the body's metabolism and immune system."
Sun Hao's first reflexology experience starts with her feet being soaked in warm water, at the same time as her shoulders are massaged.
"Chinese herbs in the water aim to invigorate blood circulation. Shoulder massage is for relaxation," says Wu.
After being dried by a towel, one of Sun's feet is wrapped in a towel and the other is covered with lotion and massaged.
"Most clients receive reflexology here in the hope of relieving neck, shoulder, back and waist problems," Wu says.
"If you sit in an office all day long and rarely work out, it is Compaq Presario 2100 battery common to suffer from a stiff neck and back. Some clients visit for sleeplessness and an upset stomach. Gynecological problems can also be relieved by reflexology."
According to Wu, reflexology can not only relieve some diseases but also reduce stress. It works even better when combined with regular sleep, a balanced diet and exercise.
Massaging the acu-points in the feet can hurt but this pain does not mean more problems in the body. Instead, gentle pressure, accompanied by mild pain, will help activate the corresponding organs.
Clients undergoing reflexology may sometimes feel their feet tingle and become sore or numb. Wu says if lumps are felt in the feet, these might indicate sickness in related parts of the compaq 2100 battery body. Regular massage of these areas will remove those lumps and alleviate the problem.
After Sun's treatment, the practitioner tells her to drink a cup of warm water and not to eat laptop battery for 30 minutes. The young bank clerk feels refreshed and vows to return.
