An interesting idea. Could potentialy save an airline millions in annual fuel bills. Thats a good 10 to 20 mins average taxi time cut off the fuel bill for each flight. Could be as much as an hour if you factor in the taxi to gate on arrival at some busy airports. Then you also have savings by not needing a tug either.
I think this has lots of potential if they get it to work.
Opinions?
