Where will you find the BTUs to charge the tugs? Isn't the theory that the
plane has free amps to spare either from an APU that must be running
anyway or batteries charged off the main engines while flying much like
free heat to warm your automobile.

Just brainstorming so this may be a completely wrong idea.

Ok, some way to electrically connect the tug to the jet to use the jet's
'free' amps? Charge the tug while it is tugging?
