Why not rig up a solar-powered fish-tank bubbler in your butt, to keep
it fresh?

Most water butts that I have seen are too deep to aerate without a
high pressure compressor. It would be an interesting challenge to make
a solar powered one.

My water butt is about five foot deep. My mains powered aquarium
aerator gives up at about two foot deep. A pipe with an air lift water
pump may work but in my aquarium days I never made one that long.
