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?

Deuterated polyethylene films as thin as 50 m have been produced using a four-post heated press method. These films are then cut into the desired shape (foil) and are used for the magnetic recoil spectrometer (MRS). The MRS is a diagnostic tool for inertial confinement fusion (ICF) experiments at the National Ignition Facility (NIF) and at the OMEGA Laser Facility at the University of Rochester Laboratory for Laser Energetics. The films produced by this method are more uniform and have fewer defects than foils prepared by previous methods. Whereas traditional films had a thickness limitation of 100 m, this new heat pressing method allows the fabrication of 50-m films, which is the desired thickness for MRS foils. The foils produced and characterized by General Atomics have decreased the neutron measurement uncertainty of the MRS instrument by a factor of 2 compared to the previous foils. This work has also been extended to fabricate thin polymer films and films with sinusoidal patterns from other polymeric materials for ICF experiments. This paper will discuss the heat pressing technique used in the fabrication of these films for the NIF and OMEGA MRS as well as other patterned and flat polymer films. The morphology of these foils and the advantages that they provide will also be discussed.
