No, it is occurring in all stars including our sun, and we would not exist otherwise. On Earth it is still experimental
Nuclear fusion is used only in experimental installations.
Nuclear fusion does not currently occur in nuclear plants. Nuclear plants use nuclear fission, where atoms are split to release energy. Fusion reactions, in which atomic nuclei combine to release energy, are not yet used commercially for electricity generation.
Nuclear Fusion
Cold fusion is a theoretical nuclear reaction that supposedly occurs at room temperature, while nuclear power plants use controlled nuclear fission reactions to generate heat and produce electricity. Cold fusion has not been reliably demonstrated, while nuclear power plants worldwide successfully use fission to generate a significant portion of electricity.
Nuclear fusion only releases energy when elements lighter than iron are involved. This is because elements lighter than iron release energy due to the process of fusion, while elements heavier than iron require energy to be input for fusion to occur.
Up to now only in H-bombs. Experiments in fusion are on going though.
Fusion is a nuclear reaction.
Nuclear fusion produces nuclear energy
Nuclear fusion
Nuclear fusion doesn't produce energy.
the only planet that is known to make nuclear power at this point is earth.
Well, if you believe in such things, the Big Bang was only a mass Hydrogen, which exploded due to massive internal forces. Hydrogen then fused into all atoms in the universe today through the process of nuclear fusion, which is the same process as that occurs in the center of our sun, and in the hydrogen bomb. Nuclear fusion is not utilized in nuclear power plants, as the only sustainable level of nuclear fusion is to large to be contained. Essentially, it would melt everybody who tried to go near a fusion power plant. Nuclear physicist are constantly working on the theoretical process of "cold fusion", but have made very little advancement. It looks like this force may just be for stars bombs and universe making theories ;).
