500MW from half a gram of hydrogen: The hunt for fusion power heats up
Nuclear fusion occurs when two atoms fuse together (usually hydrogen) to form a heavier atom (helium), and releasing a vast amount of energy in the process. This process can only occur at incredibly high ... going you need to sustain a temperature of ...
The Global Race For Fusion Power
The NIF has achieved “burn”, i.e. fusion, but not ... fission power without generating chain reactions. If a team can demonstrate a sustained reaction, start passing out the Nobel Prizes. But these are all big ifs. The circumstances required to achieve ...
Nuclear fusion reactions mark a 'milestone'
It took 192 lasers and a building big enough to contain three football fields, but physicists have finally produced a pair of nuclear fusion reactions that ... difficult to create the high pressure and high temperature needed to get the process going.
What is Fusion?
In order for the nuclei of two atoms to overcome the aversion to one another caused their having the same charge, high temperatures and pressures are required ... to power crafts through space. Fusion differs from fission, which splits atoms and results ...
Nuclear energy: The hybrid returns
As the reactions continue, however, the fuel accumulates more fission ... fusion plasma than is put in, it will require the generation of unprecedented plasma temperatures, densities and confinement times. But because the fusion component of a hybrid need ...
