Can hydrogen be the transportation fuel in an otherwise nuclear economy?
Let’s face it: The global economy should be powered primarily by nuclear power. And it probably will by the end of this century, with a still-significant assist from renewables and hydro. Once nuclear systems are dominant, the costs come down to where gas is now; and when carbon emissions are reduced to a small portion of their present state, it will become obvious that most other sources are only good in niche settings. I mean, why use small modular reactors to load-follow when they can just produce that power instead of buffering it?

Rotation of a Field-Reversed Configuration (FRC) plasma due to a resistive flux decay is numerically studied. When the anomaly factor is 10, the flux lifetime is found to be about 60 sec in a case that the external magnetic field is O.4 T and the wall radius is 0.17 m. Single-particle motions in a quasi-steady resistively decaying FRC equilibrium are calculated, and a local flow velocity is estimated by a particle-in-cell method. An electric acceleration of a betatron particle near the field-null is shown; this can cause a plasma rotation. From a comparison of the toroidal ion flow velocity profile between with and without the flux decay, it is found that the ion rotation begins at the field-null.
