Erről lemaradtál, a Honeywell, meg mások megcsinálták egy ideje:
Electric Green Taxiing System (
EGTS)
EGTS is an electric taxiing system that is used prior to
takeoff and can help airlines reduce costs by eliminating the need to use
jet engines which are not efficient on the ground. It can also reduce
foreign object damage and is environmentally friendly as it reduces carbon and other emissions created during the taxiing phase. The main landing gear is equipped with an electric motor powered by the
auxiliary power unit which allows the aircraft to push back from the gate and taxi without a tug or its jet engines.

The system weighs 300 kilograms (660 lb) and is permanently installed on the aircraft.
[2] The system can accelerate the aircraft to 20 knots (37 km/h; 23 mph).
[3]
With electric motors located on each of the main landing gear driving inboard wheels and powered by the APU generator, the EGTS system allows aircraft to push back from the gate without a tug tractor and taxi without the use of the main engines.
The Pilot Interface Unit enables the pilot to switch on the EGTS and select the desired taxi speed (forward) or push back speed (backwards). The EGTS controller receives and converts the pilot's directives into orders to power the electronics.
The wheel actuator applies the required torque and speed proportional to the wheel as per the instructions received from the Wheel Actuator Controller Unit (WACU). The WACU converts current into instructions to the electrical motor proportional to the pilot's command as delivered by the EGTS controller.

Nem egy rossz cucc, csak nem szeretik még, mert sokat bonyolít az amúgy tökegyszerű futón, meg ugye a strapabírás, stb... de alapvetően a számítások szerint az elégetett kakaót figyelembevéve megéri, elvileg egy átlagos fapados gépnél üzemanyagköltségen ha jól emlékszem 2 év alatt behozza az árát (amolyan winglet elven számolgatva a fogyasztácsökkentést)
