Energy From Nuclear Fusion


Nuclear Fusion is the energy-producing process which takes place continuously in the sun
and stars. In the core of the sun at temperatures of 10-15 million degrees Celsius, Hydrogen is
converted to Helium providing enough energy for us to sustain life on earth.
For energy production on earth, different fusion reactions are involved. The most suitable reaction
occurs between the nuclei of the two light forms (isotopes) of Hydrogen - Deuterium and
Tritium; eventually reactions involving just Deuterium or Deuterium and Helium may be used.
A brief breakdown of the fuels used are as follows, Deuterium is a very abundant isotope
of hydrogen and can be extracted from all forms of water, Tritium is not as abundant and is not a
natural isotope, instead a machine is needed to extract it from lithium. Lithium, which is the
lightest of all metals is plentiful on the earths crust, there is so much on the crust that right now
they say there is enough to provide the planet with over a thousand years of electricity.
Fusion power offers the potential of an almost limitless source of energy for future
generations but it also presents some formidable scientific and engineering challenges. It is called
'fusion' because it is based on fusing light nuclei such as hydrogen isotopes to release energy.
Effective energy-producing fusions require that gas from a combination of isotopes of hydrogen -
deuterium and tritium - is heated to very high temperatures (100 million degrees centigrade) and

The roles of man, naturally occurring trends, and earth’s cycles are considered, and an outlook for what can be expected in the near and distant future is given. ‘The uneasiness of modern man arises from a rupture between himself and nature that leaves him homeless within the universe...’ William Barrett II.

The constant and increasing pressures we are exerting threaten our planets ability to sustain life itself. Change-in the way we think , and in the way we live-is needed now. Global warming is the most urgent environmental problem the world will face in the next decade and the next century. Few, if any, trends are more important to our future than climate change caused by human activities. Scienti

    HOW USEFUL IS DENDROCHRONOLOGY TO ARCHAEOLOGY HOW USEFUL IS DENDROCHRONOLOGY TO ARCHAEOLOGY? Dendrochronology is a technique that has been in use for most of the twentieth century. Essentially the process revolves around tree rings. In a moderate environment, trees grow by one ring each year and thus, to an extent, by examining these ring sequences, it is possible to understand the conditions in which the tree grew, year by year. The resultant pattern is then comparable with patterns from other

Pope Innocent II organized the conference in 11391 because of a crossbow. Approximately 800 years from this conference, the Cold War has begun. The potential of mass destruction could occur at any moment. More efforts for mining and technology went toward constructing nuclear weapons. Missiles, such as,

    Chernobyl 3 Chernobyl Chernobyl was the greatest nuclear disaster of the 20th century. On April 26th, 1986, one of four nuclear reactors located in the Soviet Union melted down and contaminated a vast area of Eastern Europe. The meltdown, a result of human error, lapsed safety precautions, and lack of a containment vessel, was barely contained by dropping sand and releasing huge amounts of deadly radioactive isotopes into the atmosphere. The resulting contamination killed or injured hundreds of

    chemistry (ocean) What is an iceberg? Why are they blue or green? An iceberg is a large floating block of freshwater ice that has broken off the edge of a glacier and been carried out to sea; about 90% of its mass lies under the water. The bluish streaks of clear, bubble free ice often seen in icebergs results from the refreezing of melt water which fills crevasses formed in the glacier as it creeps over land. The ice is blue because of the natural light scattering characteristics of pure ice. O
