Cool Submarine !

[TaoJones]

How cool is this: a pedal-powered submarine:

submarine, Scubster, personal submarine, leisure submarine, yellow submarine, muscle powered submarine, sous-marin, submarino, u-boot

I want one.

I wonder how they control the buoyancy of the submarine. You would not want to be in one of these if the buoyancy got out of control and it made an uncontrolled ascent giving you air embolism or the bends.

The question is, with its greater wetted surface area yet more efficient shape, does it take more oxygen over a given distance for a diver to kick normally or to pedal this thing?

Is it essentially an underwater pogo stick that takes more energy to use it than to walk normally?

[Sunspot Baby]

I think it is flooded thus the driver is breathing on SCUBA so no realy buoyancy of its own.

Could be pedaling a propeller is more effecient use of muscle energy than kicking a flipper up and down.

Looks like a solution looking for a problem to solve.

It would work ok in areas with little to no currents such as bays and protected sides of islands. It's definitely a scuba use unit and the 'efficiency' depends solely on the operator's fitness level IMO.

Still wished we had met (Dave/Exit Only) when I worked down there I could've taken you for a submarine ride....Guess I was too intimadated by the totally rigged out for cruising Exit Only when I spied her from the Causeway Bridge, and figured you were just another cruiser heading somewhere. Had I only known!
