Concept innovation remains a necessary component of a healthy fusion program: even as ITER goes ahead, the mission of the world fusion program remains to produce an economic fusion reactor, the path to which entails concept innovations as well as innovations in the mainline devices. One subset of concept innovations entails simply connected devices (no material linking the plasma), and if practicable, would lower the cost of the fusion core significantly. Simply connected magnetic fusion concepts entail the frc, spheromak, mirror, z-pinch and hybrids (including magnetized target fusion). The US policy towards these innovative concepts, developed over the last 15 years, is summarized in this paper. The progress in understanding and performance obtained over a similar time-frame, is also summarized. A summary of future directions for these exploratory concepts is given, by reviewing general and concept-specific descriptions, cost of electricity arguments and plans for the integration of concept innovations into the national/international fusion program.
