NOVELTY - The apparatus has aerodynamically-shaped wheel spokes (21) connected to a motor (26) via motoring shaft (22) that is concentric, coaxial, and free to rotate independently within a generating shaft (24). The generating shaft connects a generating propeller (23) to a generator (25) to enable simultaneous motoring and generating within the wheel. The motor, generator, motoring shaft, generating shaft, and propeller are located downwind of the spokes and out of the vehicle slipstream so as not to cause drag penalty.    USE - Apparatus for wind energy recovery in wheels of vehicles, such as hybrid and electric vehicles.    ADVANTAGE - The apparatus enables the efficient, economical and esthetic energy recovery from wind passing through the wheel spokes, at the same time allows for motoring of the same wheel without any energy penalty to the motor or drag penalty to the vehicle extending the available electrical energy on-board for either electric or conventional internal combustion vehicles. The wheel spokes generate accelerating slipstream energy for efficient recovery by the propeller in the form of rotational energy for conversion by the generator as desired. Eliminates use of alternators, allowing for more predictable and consistent energy recovery in compact configuration for wheeled vehicles and allowing for greater fuel efficiency. The absence of gears, also known as direct drive, reduces mechanical losses typically associated with gears. The load on motor is reduced without gearing, allowing motor to output more rotational energy per given unit of input energy thus increasing efficiency of the motoring section. Increased efficiency of the motoring section improves the production of slipstream, resulting in the improved efficiency of slipstream energy recovery. The absence of gears reduces the overall inertia of the generating section, improving the efficiency of the generating section. The use of concentric rotatable shafts reduces the lengths and weights of the shafts, as compared to non-concentric shafts, thus enabling a more compact and more attractive commercial apparatus implementation. The use of concentric rotatable shafts also results in weight savings contributing to further lower overall inertia in the generating section, thus leading to improved generator output. The weight savings from reduced shaft lengths and the use of direct drive reduces manufacturing costs. The apparatus simplicity contributes to reliability and robustness as well compactness. The ability to recover slipstream energy regardless of whether the propellers are co-rotating or counter-rotating is realized using the apparatus. As long as the vehicle that the wheel is attached to is moving, energy will be recovered. The faster the wheel rotation, the greater the slipstream produced, the greater the energy recovered by the generating section, allowing for a greater increase in cruising and maximum speeds of electric vehicles over longer sustained periods. The range of electric vehicles is improved with the application of the apparatus, because they would no longer be strictly limited by the charge capacity of on-board batteries. The output of generator can be used to charge batteries while in motion or power accessories that would otherwise drain the batteries, reducing the discharge rate of batteries and extending the range of the vehicle. The payload, or useful carrying capacity, of electric vehicles is also improved because it reduces the need for more batteries to be on-board. Battery charging times and the number of charging cycles required is also reduced because of the mostly continuous charging taking place while the vehicle is in motion. The non-use of the alternator allows for flexibility in the configuration enabled by the use of gears, allowing for generator to be situated unaligned from generating shaft. Generator can now be more easily disassembled and even removed entirely for maintenance and repair.
