> the problem with hydrogen fission It's actually fusion they're talking about here, not fission. > rather containing it ... You're referring to using fusion as an energy source. Here they're just talking about the energy liberated in individual collisions not in sustainable reactions. > suggest that quark fusion would make any of these problems easier The exact opposite. The article points out that there's no real chance of a chain reaction so you couldn't even produce a bomb never mind a sustainable energy source.
