There is one problem with nuclear fusion that lasers cannot solve, however: the price.
Carbon, oxygen, iron, and the like had to wait for stars-especially the massive ones-to form and create heavier elements via nuclear fusion.
Unlike the sun, whose density is such that it supports nuclear fusion that generates bright sunlight, Gliese 581 is a red dwarf, so-called because the star is small and dim.
a nuclear reactor that uses controlled nuclear fusion to generate energy.
The star used to be like the sun, a "main sequence" star that burns hydrogen by nuclear fusion, producing helium.
Systems of this sort are being used in an effort to produce controlled thermonuclear fusion reactions.
For the long term the plan lists nuclear fusion, solar electric energy and the study of breeder reactors as priorities.
A similar trend to scientific cooperation on a global scale was apparent in many other fields, like meteorology, astronomy, nuclear fusion, and space.
Well, the only way that we might survive — the quality of life is at stake here is nuclear fusion.
A nuclear fusion is a thermonuclear reaction.
Astronomers ascribed them to thermonuclear fusion of hydrogen or helium or to the sudden accretion of matter onto the star.
But accelerators could potentially produce nuclear fusion, which fuses atomic nuclei together.
"This neutron star was born so hot that nuclear fusion happened on its surface, producing a carbon atmosphere just 10 centimetres thick."
Time, then, to rekindle a little glamour, by using lasers to bring about nuclear fusion, the great prize of energy research.
