... JP8 MICRO-COMBUSTOR Numerous designs for JP8 combustors at larger scales exist, and several companies have developed burners in the approximate power range required for this project. The challenge is to integrate them with the novel thermophotovoltaic system, or alternatively modifying the existing microcombustor to be compatible with JP8.

... Additional required development efforts include transitioning from small batches of small diameter wafers to large batches of large wafers, making the tantalum wafers compatible with non-academic cleanrooms. For example, by mounting the thin tantalum substrate on silicon wafers, and streamlining the process to eliminate the need for manual real-time adjustments to process parameters.
