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?

Results of global discharge modeling and simulation of the Hanbit magentic mirror discharge are given and an RF heating theory and its results are presented.
In the global discharge model, global transport equations of ions and electrons are solved including and impurity recycling equations. Based on the developed global model, the effect of oxygen impurity on the discharge characteristics is simulated. Also, Maxwell-Boltzmann equations are solved by the mode analysis technique to develop a theory of the radio frequency (RF) wave heating mechanism in a magnetic mirror discharge condition. Utilizing the solution the discharge impedance is calculated for the case of slot antenna. Moreover the plasma resistance is divided into an electron resistance and and ion resistance which indicate absorbed powers by electrons and ions, respectively.
