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.

Many amateurs would give their right arm for a functioning helium
balloon. It's the sort of thing that most LF band aficionados can only
dream about. It's a lot easier to obtain electricity than helium.





Weather balloons can be found for sale all over the web, and in all
sizes and skin thicknesses. They work quite well for hoisting a wire.
I tried it one time with two NWS balloons (about 3 feet in diameter,
IIRC); the only problem was they bounced against each other constantly.
Next time I would arrange them so that one is above the other.

A tank of helium isn't overly expensive, either.
