Plans call for first-generation fusion reactors to use a mixture of deuterium and tritium — heavy types of hydrogen. In theory, with just a few grams of these reactants, it is possible to produce a ...

Fusion is the Opposite of Fission Nuclear fusion and fission might sound similar, but they are fundamentally opposite ...

For fusion to occur, hydrogen atoms are placed under high heat and pressure until they fuse together. Meanwhile, fission splits a heavy element (with a high atomic mass number) into fragments.

Fission splits a heavy element (with a high atomic mass number ... Can fusion reactors be used to produce weapons? No. Although hydrogen bombs do use fusion reactions, they require an additional ...

Fusion technology is a long way from powering a grid — if it ever will. Dozens of fusion startups have launched anyway.

which was made by fusing hydrogen, into heavy elements like carbon. But most stars are not massive enough to create the pressures and heat necessary to burn heavy elements, so fusion and heat ...

Deuterium (D) fusion is one of the simplest ... On Earth, water contains a natural miniscule amount of heavy water, with deuterium replacing one or both hydrogen atoms to exist as HOD or DOH ...
