Several proposals on the power production application of neutronless fusion reactions and the ~MeV reaction are reviewed. Compressing low tritium fuel by thermal radiation from one or more D--T microexplosions possibly combined with one or more drivers is considered as the optimum ignition strategy for microexplosions with physically important D--D fusion reactions. Results are presented which show the incorrectness of three assumptions that argue that the ignition of the ~MeV reaction can be facilitated by chain reactions. The delivery of lunar as a thermonuclear fuel component for large-scale power production on the Earth is discussed from the viewpoint of the expedience problem.
