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?

Statistical property of ion and electron temperatures on various plasma parameters has been investigated in REPUTE-1 reversed field pinch (RFP) plasmas. The scalings laws are expressed in terms of the plasma current, loop voltage and line averaged density. Dependence on other parameters seems to be weak. The operational range of density is wide in REPUTE-1, and it is limited by Hugill number H*~1, which is another expression of Ip/N, where Ip is the plasma current and N is the area density. Obtained scaling laws areTi∝VLoop1.3×nˉe−0.3,Te∝Ip0.8×nˉe−0.2, where ne is the line averaged electron density and VLoop is the loop voltage. The electron temperature has roughly same dependence as other RFP devices. The Ip dependence of ion temperature is not found in REPUTE-1, while some RFP devices demonstrate linear dependence.
