I've been trying to think of some cool ideas for Primitive Lift Modules, Perhaps I could do something like pigskins sewn together to make balloons, or hide balloons, mechanically its a fairly simple implementation but I'm just trying to come up with graphical and mechanical specifications.

To start with, I'm not sure how big I should make it.

The standard balloon is 2wide b 3tall, so ideally I could make something of a similar size or smaller than the current balloons in the game.

Right now my thought is to make it the same size as the current balloon, to make it easy to retrofit some early game designs into viable AI ships, and then add new graphics, make it slightly heavier and with a little bit less lift and hp.

I'd also like to ad a new module called "Ballast Corridor" which would function like a normal corridor, except the overhead space is filled with suspendium baloons and it would slow down crew significantly walking through it. Making it a little bit more expensive and perhaps a bit more prone to explosion or fire than a normal would balance out the space efficiency you get from cramming more value into a corridor on top of slowing crew down.

For propulsion I've been considering implementing a smaller more primitive sail, and a rowing galley that would take several crew to man but would provide "low tech, high maintenance" propulsion for ships. I'd love to hear feedback on these ideas.
