A joint venture between Safran and Honeywell is creating the Electric Green Taxiing System so that the main combustion engines of the European jet maker Airbus' airplanes are not being used. This is said to reduce fuel consumption by 4%.
Seems the airline industry is beginning to discover the benefits of hybrid technology. The recent airshow in Paris included an A320 modified to use electricity to power the wheels, so that it could taxi without using jet fuel. Just as with cars, the system saves gas and reduces emissions.
