   "On Earth, fusion experiments typically require large, expensive equipment to   
   pull off.   
      
   But researchers at NASA’s Glenn Research Center have now demonstrated a   
   method   
   of inducing nuclear fusion without building a massive stellarator or tokamak.   
   In fact,   
   all they needed was a bit of metal, some hydrogen, and an electron accelerator.   
      
   The team believes that their method, called lattice confinement fusion, could   
   be a   
   potential new power source for deep space missions. They have published their   
   results in two papers in Physical Review C."   
      
      
   "“What we did was not cold fusion,” says Lawrence Forsley, a senior lead   
   experimental   
   physicist for the project. Cold fusion, the idea that fusion can occur at   
   relatively low   
   energies in room-temperature materials, is viewed with skepticism by the vast   
   majority of physicists. Forsley stresses this is hot fusion, but “We’ve   
   come up with a   
   new way of driving it.”   
      
   “Lattice confinement fusion initially has lower temperatures and   
   pressures” than   
   something like a tokamak, says Benyo. But “where the actual deuteron-deuteron   
   fusion takes place is in these very hot, energetic locations.” Benyo says   
   that when she   
   would handle samples after an experiment, they were very warm. That warmth is   
   partially from the fusion, but the energetic photons initiating the process   
   also   
   contribute heat."
