The reactors use " tristructural isotropic particle fuel" , in which blobs of fissile uranium (along with oxygen and carbon) are wrapped in layers of carbon and silicon carbide.
Chipmakers hope gradually to replace the silicon used in most processors with gallium nitride or silicon carbide, both of which can handle higher voltages.
ULED projectors inside the frame of Orion beam graphics in front of your vision via wave guides in the lenses, which are made of silicon carbide and not glass.
