    The primary difference between an electrical and an air powered gyroscope is just that, the means of powering the the gyro to spin at high speed.

    The other difference that one should keep in mind is, unless equipped with its own power source, and electrically driven gyro will become unusable in the event of a power failure. Vacuum driven instruments are limited to keeping the vacuum pump in one piece and turning from engine power.
