Other methods even less likely to succeed include the muon-catalyzed and anti-matter catalyzed varieties.  
One recent, and unlikely, method for achieving this was given experimental evidence by Rusi Taleyarkhan, who applied sonoluminescence.  Other methods even less likely to succeed include the muon-catalyzed and anti-matter catalyzed varieties.  An important goal for the useful application of this is the ignition point, but an easier goal is the Lawson Criterion, or break-even point, where a net energy is actually created.  FTP, name this nuclear process in which two atoms combine to create one larger atom, and which takes place in our Sun.
