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?

A new 28 GHz - 1 MW gyrotron has been developed for ECRH system of GAMMA 10 tandem mirror. To achieve the design target of the new gyrotron, which is 1 MW output for 1 s, the magnetron injection gun (MIG) and cavity were designed in detail with calculation codes. A first tube has been fabricated, and performance test is in progress. The maximum output power of 1.04 MW and the maximum output efficiency of 40.6% were obtained with short pulse operation. However, at the same time, it was confirmed that the output efficiency had decreased with the increase of beam current. This is explained with decrease, which is a one of issues to develop a higher efficiency gyrotron.
