Project Ascensio was an award-winning design effort for a 'luxurious' mobile ocean-based spaceport tethered to an asteroid counterweight in geostationary orbit, as part of the Jacques Rougerie Competition. By Jordan William Hughes. www.artstation.com/artwork/PX3848

I like the idea of space elivators being vehicles unto themselves, floating halway between the water and geostationary orbit and slowly adjusting their position to avoid storms and political complications. An active structure that will collapse if not carefully guided.
