I interviewed for a company working on this project. Their goal is still jet fuel but with greatly increased efficiency by replacing components traditionally driven by the shaft (such as the intake and compressor) with electrically driven systems that in turn take load off of the generator. The net increase in efficiency more than balances out the cost of the electrically driven components, thus increasing the efficiency of the entire system.

Feels like an engineering wet dream, but i was willing to take their money and tell them how smart they sounded lol predictably, the project is waiting on more funding
