Assumed covered...
Perhaps use some type of miniature space heater powered by a little solar panel?
Mount it on a cinder block.
The small amount of heat will create upwards air pressure and movement by itself.
And the tub sides + cover will make the space inside warmer by just a degree which might help drive out moisture.
Maybe...
Or would it just bring in more humid air to condense on the cold walls?
