Third Generation Fusion Fuel
Third generation fusion fuels produce only charged particles in the primary reactions, and side reactions are relatively unimportant. Since a very small amount of neutrons is produced, there would be little induced radioactivity in the walls of the fusion chamber. This is often seen as the end goal of fusion research. 3He has the highest Maxwellian reactivity of any 3rd generation fusion fuel. However, there are no significant natural sources of this substance on Earth.
- 3He + 3He 2p + 4He (12.86 MeV)
Another potential aneutronic fusion reaction is the proton-boron reaction:
- p + 11B → 34He
Under reasonable assumptions, side reactions will result in about 0.1% of the fusion power being carried by neutrons. With 123 keV, the optimum temperature for this reaction is nearly ten times higher than that for the pure hydrogen reactions, the energy confinement must be 500 times better than that required for the D-T reaction, and the power density will be 2500 times lower than for D-T.

Famous quotes containing the words fuel, generation and/or fusion:
“It is now many years that men have resorted to the forest for fuel and the materials of the arts: the New Englander and the New Hollander, the Parisian and the Celt, the farmer and Robin Hood, Goody Blake and Harry Gill; in most parts of the world, the prince and the peasant, the scholar and the savage, equally require still a few sticks from the forest to warm them and cook their food. Neither could I do without them.”
—Henry David Thoreau (1817–1862)
“One generation plants the trees under which another takes its ease.”
—Chinese proverb.
“No ... the real American has not yet arrived. He is only in the Crucible, I tell you—he will be the fusion of all races, perhaps the coming superman.”
—Israel Zangwill (1864–1926)
