    Can it be used to power a turbine? Or just propulsion like a sail, because what if we want to go towards the sun…?

    It also has diminishing returns in relation to distance to the sun.

        In space…? Because that requires moving one part while the others stationary…. The friction from generating power would spin the rest of the satellite, or would need to expend power to resist it.

        Windmills have used sails as fins for long time lol, its nothing new, im trying to get you think critically here.

          Or moving one part opposite the direction of another, to create resistance.

          There’s plenty of conversation to be had about efficiency, heat venting, gross productivity. But “you can’t capture energy from another moving body” is something billards disproved several centuries ago.
