Ok. Several hundreds of uA is the minimum that these things appear to
require. Maybe a super light one would rise with 50 uA. I tried to make
one powered by an electrostatic machine that coud produce up to 100
uA. The power was not enough, but the wind was significant. The question
is just how to make a solid enough structure with really minimum weight.
Maybe paper painted with conductive ink instead of metal foil? Or a thin
wire net?

One with many small sections in parallel. The same voltage but lots of
current.
