!!! Brainstorming
!! Solar sail for use in stratosphere
The idea is to use the that that there is still some atmosphere left.
The sail would need to:
# absorb light on one side an become hot

# this would create a difference of temperature between the two sides and change the temperature of the surrounding atmosphere.
# the temperature difference could result in a pressure difference which would push the sail
