Can we increase the pulling power with the general size? Can we make an extremely light structure with a great pulling power? Can we use affordable materials? Will it self-right? Can Protei be inflatable and flexible at the same time (depending on pressure and joints)?
The general concept here was to make a boat that would be extremely light.
Ocean Blimp being mostly air, it is no surprise it is a very lightweight boat.
All the materials of Ocean Blimp come from the local ACE Hardware Store.
