There's also "inertial electrostatic confinement" (IEC) that seems promising: > Theory for a gridded inertial electrostatic confinement (IEC) fusion system is presented that shows a net energy gain is possible if the grid is magnetically shielded from ion impact. A simplified grid geometry is studied, consisting of two negatively-biased coaxial current-carrying rings, oriented such that their opposing magnetic fields produce a spindle cusp. Our analysis indicates that better than break-even performance is possible even in a deuterium-deuterium system at bench-top scales. The proposed device…

So much I want to say here... I'm part of the choir to whom the author is preaching but I find this weak tea. (Although he's not preaching, he's RFC'ing his assumptions.) If we grant that fusion isn't around the corner (and I don't, see "Fusion in a magnetically-shielded-grid inertial electrostatic confinement device" https://arxiv.org/abs/1510.01788 abstract: "Theory for a gridded inertial electrostatic confinement (IEC) fusion system is presented that shows a net energy gain is possible if the grid is magnetically shielded from ion impact.
