I’m fascinated by Deep Sea Vehicles (DSVs) and want to know more about them or see a discussion arise.
Basically, what I’ve gathered so far is mostly about Triton’s Limiting Factor DSV, and the old Trieste Bathyscaphe.
Buoyancy - Some lighter-than water fluid. Is this true with the Limiting Factor? Use of shot/metallic-weights for ballast suggests this hasn’t changed?
Pump-limitations - most powerful pumps I read about so far are limited to about 5,500meters, so there’s an inability to control ballast through pumps at this time?
Controls - how does a DSV pilot control the craft? Do they have to poke holes into the pressure hull? Thrusters, dive planes (if any) and release of ballast all have to be controlled, but the pressure hulls are solid spheres aren’t they? Radio controls?
Battery supplies - particularly, Limiting Factor kept itself on the bottom with slight positive buoyancy and downward thrust. How much energy did this consume?
Power supply - is there a way to engineer a thermoelectric generator to provide some power supply? Are there other power solutions other than just battery?
