Nice suggestion :-) A little water in the bottom, with a small pump or
some sort of passive tracker to move it around from one pouch to another?
Or maybe this should be a flying funnel, a sunscoop with a transparent
top and shiny Compound Parabolic Concentrating conical sides...
As for the dirigible floor lamp, would you say a dry cleaner bag with
150 F air from a bulb with a high power/weight ratio, or some very thin
tungsten or nichrome wire, attached to two fine copper wire tethers?
