      The flying submarine is a famous sci-fi icon. There are many biological versions, from flying fish to diving birds. A few partial marginal technological instances have been developed, but none really mastered the multi-modal freespace.

      Many ordinary kites can fly above or in water. Mixing the modes is simple, just dive a Rev kite into a water current and steer it to the surface for relaunch. Mothra1 seems suited for amphibious work. A key operational idea is to have a fixed or variable buoyancy nose on the subkite so that it surfaces upright for take-off. In flight, pendulum mass balance then keeps the nose pointed up. Most basic AWES concepts have underwater counterparts.

      Submarines face traditional challenges that kites can solve. A kite in wind can tow a submarine under water and solve stubborn fuel/oxidizer, nuke, and battery-capacity shortcomings. Imagine what is possible with "oceans of clean energy" tapped by combinations of flight and submarine kite operations.

      A 3D freespace latticework is in some ways easier underwater (neutral buoyancy without LTA). Such latticework can span "inner space", the vast volume of the seas, and tap currents, host habitats, or support any desired infrastructure. Buoyancy control and anchoring are important. Air-bags and kite compressed-air are cheap buoyancy. Anchoring works pretty much the same under water, as do the laws of fluid-dynamics.
