Let us think about this case.

When there are anti-hydrogen and anti-deuterium, and there is a fusion reaction between them.

Is it a exothermic reaction or endothermic reaction?

For example

hydrogen + Deuterium fusion------------> exothermic +

Hydrogen + Anti-hydrogen fusion -----------> exothermic +

Anti-hydrogen +Anti-deuterium fusion -----------> ???

 

Is Hydrogen + Anti-hydrogen fusion energy 2 m(hydrogen mass) C² ?

How do you propose to fuse matter and antimatter? I would think that they just annihilate and everything is converted to energy, with an extra particle released here and there, depending on the situation.

 

I saw something last night that stated that annihilations usually release more energy than fusion. As far as fusing two antimatters go, thats pretty far out there, but I would venture to say that energy is created, though when you factor in what it takes to create antimatter, your returns are probably diminished.

hydrogen + Deuterium fusion------------> exothermic +

Hydrogen + Anti-hydrogen fusion(annihilation) -----------> exothermic +

Anti-hydrogen +Anti-deuterium fusion -----------> Anti-helium ?

 

If mass loss occurs, energy will be released. According to present knowledge, I think, the reaction is assumed as exothermic reaction.

Fusing anti-deuterium to get anti-Helium would be exothermic.
