New Jet Engine Paradigm

Synopsis :
The energy generation phase is separated from the propulsion phase .
Speed enhancements are of the order of 300%

Discussion
The old-style jet engine is broken up into the combustion stage and the propulsion stage .
The combustion stage is the old turbine or piston system .
The propulsion is electrically driven fans .
The combination with smart systems gives about 1/3 of the cost , and enables cheap supersonic systems .

As usual , Burt Rutan has been ahead of the pack .
See Burt Rutan's Flyng car .This would actually work .

Notice the tiny primary powerplants (2 X 450 cc) .

Why was it not done before ?
They couldn't .
It requires materials and control systems not available before .
