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?

The separation capability of the charged particles is one of the most important requirements for direct energy converters (DEC) of D-3He fusion reactors. Yasaka, one of the authors, has demonstrated the principle of the Cusp DEC on a small-scale experimental device. Analyses of the device with a two-dimensional approximation and comparison with the experimental results give the following results. (1) The input power of plasma beam is estimated as P = 2W × E1.5, compared with the experimental results, where E is the ion energy and normalized with 0.1keV. (2) The current at point cusp tends to saturate as the ion energy increases as the experimental results show. (3) Ion current at point cusp depends on the shape of the magnetic field more strongly than its strength.
