That sounds good, practical, even. I've seen film of power trailers
behind Landrovers which seemed remarkably good at ploughing through mud
in off-road tests. Do you know if there are stability problems with these
rigs at highway speeds? I ask because I expect mining trailers would be
somewhat slower and the film didn't show anything operating at much over
10 mph.


I guess it could be done wrong so stability problems ensued. However,
electric wheel motors create an opportunity for dynamic stability
control. One motor could be instantly braked while the other powered
forward to counter sway. Since the motors are directly coupled to the
wheels, this could happen at the speed of electronics. Accelerometers
in the trailer would sense sway. I would think it could be done in a
way to create dead solid stability.

SparrowHawk owners, and maybe PW-5 owners, probably are looking forward
to towing with EV!

A lot of the glider pilots I know bring the glider over the mountains to
Ephrata and leave it there all season, then take it home. They could
borrow or rent a vehicle to do that, and use an EV or other high mpg car
to go soaring the rest of the time. Pilots with self-launchers often
avoid a lot of towing, since they can fly from a nearby airport instead
driving to someplace with a tow plane, and don't need retrieves. Works
for me.

I like the idea of a powered trailer, though.
