Abstract: Nuclear fusion energy powers the Sun. The objective of harnessing this abundantly available potentially non-radioactive source of energy on Earth has widespread interest. However, the zeroth-generation large ITER plasma fusion reactor under construction requires nuclear-weapon tritium cycle generating high energy neutrons. My personal research interests are focused on fusion concepts relying on alternative light isotope nuclear reaction cycles that sidestep the equilibrium plasma conditions which are beyond near-future technology reach. In this talk I will discuss nuclear fusion in general; highlight ITER at cross-roads; and introduce muon-catalyzed nuclear fusion, laser-driven proton acceleration used to spark micro-explosion fusion, and laser-driven coherent plasmon field induced fusion. The three modern high-tech approaches are under worldwide active study supported by both private and government sponsored research programs.
