How efficient is Nuclear Fission and Nuclear Fusion compared to anti-matter as an energy source?

Recommended Posts

I read somewhere that,

fission converts 0.1% of mass to energy
fusion converts 1% of mass to energy
anti-matter converts 100% mass to energy


is this correct and how so?

Only antimatter example is correct.

 

It's too much generalization. Different kinds of fusions, fissions release different amount of energy.

H-2 + H-3 -> He-4 + n0 + 17.6 MeV

 

17.6 MeV is just 0.376% of whole energy carried by source particles. ~3 times less than 1%

 

Other fusions release less energy per mass.

 

H-2 + Li-6 -> 2 He-4 + 22.4 MeV

22.4 MeV is 0.3% of whole energy.
