“…However, oxygen-enriched combustion and recuperative arrangements (heated combustion air) can be used to achieve even higher temperatures [6]. Solid ceramics such as silicon carbide and porous ceramic gas combustors, as well as metal and rare earth materials, have been used for the emitter [7,8,3,4,[9][10][11]. Commonly used in solar applications, silicon photocells can be used to produce electric power from incident light with wavelengths shorter than 1 lm.…”
