How about a tethered helium balloon instead? This way you don't have
to worry about powering the thing. Bell wire will handle 100 watts all
day without turning into smoke.

Then (for a full sized Top Band vertical) you'd better be
prepared for some VERY SERIOUS static electricity issues.
(And, it won't be vertical. It'll be a "slooper", I believe.)

One Field Day we threw up a cross-valley long wire (running horizontal,
of course) and, after the violent static display made itself known
inside the Field Day trailer, several fellas got knocked on their asses
trying to get it disconnected and away from all the other gear and
antennas around the site. That sucker was approx. 2200 feet long.
(Could've gotten 100 pts for "Natural Power", I s'pose...)

The Colorado Rockies: Low humidity - steady breeze -- sure was exciting
for awhile!
