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?

We developed a production tungsten sputter coating process to uniformly deposit tungsten on 840 m outer diameter GDP shells using a bounce coating technique. We were able to control the tungsten-coating rate and therefore coating thickness based on gravimetric analysis. At the end of our work we could routinely produce uniform 0.5 m tungsten coatings on GDP shells with a Δ wall 0.04 m. Techniques were developed and applied to measure coating uniformity based on x-radiography and x-ray fluorescence data. Typical surface roughness values for bounce coated shells having a 0.5 m tungsten coating were 40 to 50 nm RMS. Stationary GDP shells were coated with 0.5 m tungsten and found to have surface roughness approaching 10 nm RMS, which was similar to the roughness of the underlying GDP mandrel surface. This result indicates that coating processes with less agitation such as tap or roll coating may produce much smoother tungsten coatings
