A flying car with one or two Hydrogen Powered Turbines that feed an electric generator and so on an electric engine on each wheel. On flying mode, most load is retired from the generator on the turbine, so the turbine car run free and thrust the car. Also wings pop-off from below the car and return there for Road Mode.
The advantages of the Power Source are that it is lighter than a battery pack, it can thrust the car into flying, the electric driven wheels allow controlling torque on each wheel in real time as a driving assist. Finally and most importantly, it is a sustainable ecological source of energy.
