i disagree, the tesla turbine would be perfect for the injector.
It has the notable characteristics of no physical mechanical impedance to fluid flow, it works off of boundary layer viscosity, works with either liquid and gas fluids or mixtures, and can handle large changes in acceleration of the drive fluid without damage to the turbine. You could run water, steam, expanding hho, or any combination thereof through the turbine without damage, and my personal plan is to have the injector mounted in an expansion/combustion chamber that feeds into the turbine, and you can fire the injector cycles at any frequency you want, and the explosions will create rapidly accelerating gasses that are forced into the turbine, and this wont damage it. you can take it right into the hydrogen fracturing process and get an increased energy yield, and the turbine can still take it. what's more than that is you can run it on the injectors plus pure water which will absorb excess heat and power the turbine with steam as well, because it can work on various fluid mixtures without harm you can do what ever you want to it without changing the turbine at all. you can run a generator perfectly, you will need a fancy transmission if you want to run this in a car though, because you will be working with over 30,000 rpm and have to gear that down, but the torque would be insane.
