A turboalternator for a hybrid motor vehicle includes at least one compressor, at least one turbine, at least one alternator disposed between the at least one compressor and the at least one turbine, and a common shaft interconnecting the at least one compressor and the at least one alternator and the at least one turbine.

DETAILED DESCRIPTION It is, therefore, one object of the present invention to provide a new and improved hybrid motor vehicle.
It is another object of the present invention to provide a turboalternator for a hybrid motor vehicle.
It is yet another object of the present invention to provide an integrated alternator, compressor and turbine for a turboalternator of a hybrid motor vehicle.
It is still another object of the present invention to provide integral bearing lubrication and rotor cooling for a turboalternator of a hybrid motor vehicle.
It is a further object of the present invention to provide a tapered hydraulic fit for compressor and turbine impellers for a turboalternator of a hybrid motor vehicle.
It is still a further object of the present invention to provide a hollow titanium compressor for a turboalternator of a hybrid motor vehicle.
To achieve the foregoing objects, the present invention is a turboalternator for a hybrid motor vehicle.
The turboalternator includes at least one compressor, at least one turbine and at least one alternator disposed between the at least one compressor and at least one turbine.
The turboalternator also includes a common shaft interconnecting the at least one compressor and the at least one alternator and the at least one turbine.
One advantage of the present invention is that a new and improved hybrid motor vehicle is provided that is energy efficient, low emissions and offers the performance of a conventional fossil fuel powered motor vehicle.
Another advantage of the present invention is that a turboalternator is provided for a hybrid motor vehicle.
Yet another advantage of the present invention is that the turboalternator has two alternators arranged independently and eliminates the need for gears to connect the turbines to the alternators.
Still another advantage of the present invention is that the turboalternator has integrated the alternator with the compressor and the turbine, eliminating the need for gear reduction.
A further advantage of the present invention is that the turboalternator has integral bearing lubrication and rotor cooling for the rotor of the alternator
