Aneutronic fusion would be lighter-weight, but it's good to see another concept we can learn something new from. There are two aneutronic fusion projects to look at. Polywell has become a Navy project last I heard and focus fusion (DPF) is working on an all-tungsten electrode, after which we might see the very first experiment without electrode contamination from arcing in the contacts vaporizing metal.
