Shrouded makes sense. A turbofan relies on combustion though as I understand it so not sure that could be replicated with electric only. Could be some way to get more power / efficiency out of electric only systems that has yet to be invented but electric is already more efficient than IC engines (and I would have to think jet propulsion) so we’re already ahead just by going electric.

Sorry I wasn't more clear. It is the "fan" part of turbofan that makes it efficient, not the "turbo" part. The turbine can and does create thrust, but it's relatively inefficient. So they add a "shrouded fan" to the output shaft of the turbine to increase the efficiency of the turbine.
We can add a "shrouded fan" to the output shaft of an electric motor to make the most efficient thrust from the output of the electric motor.

Yeah no worries, I’m with you on the shrouded part.
