Gallery: French Engineers Design a Pedal-Powered Submarine

 

First there was the bicycle, then the pedalo boat, then the pedal-powered aircraft — and now, thanks to a team of French engineers, the world has the pedal-powered submarine. The mini-sub, nicknamed the ‘Scubster’ is entirely human-powered and is designed so that the ‘driver’ only has to pedal to propel it underwater. The craft features a pedal belt connected to a twin-propeller system that, depending on the fitness of the driver, can reach speeds of up to 8km an hour (5mph). The mini-sub can currently reach a depth of 6 meters (20 ft), making it perfect for peddling through rivers, and shallow ocean excursions.

    It seems really, really big. I don\’t know why the volume is so large. Since it fills with water, that is a huge mass you have to push around with pedals. I don\’t know why it can\’t be just a fairing, pedals and drivetrain, and maybe flaps you wear on your hands. It could be face forward to minimize the frontal cross-section. The reduction in drag and the more efficient propulsion should make it superior to flippers. (Propellers are more efficient than paddlewheels. Are they more efficient than flippers?) On the other hand, the water will create drag on your legs, so maybe it is a wash.

    Great, did you see the movie http://bit.ly/iI5kmQ

    Was this project influenced by Barney Rubble (i.e. The Flintstones)

    Any scuba diver knows oxygen is toxic below 33 feet. A scuba diver breathes “compressed AIR” or NITROX. This is neat but unless pedaling is more efficient that fin swimming, bottom time would be less. Also the transition from being part of the machine and free swimming to investigate something wasn’t mentioned. This is more of a concept than a practical dive tool.

    The drive must wear an oxygen tank or just an air tank?

    The speed is the only advantage over just swimming with fins. I don\’t see this being used in a river where the current would almost cancel out any speed gain. Maybe a shallow lake or shallow ocean depths.

    I would never be bother lugging one of these around.

    Still it\’s a neat human powered vehicle.

    I don’t understand what it’s good for. Is pedaling a water-filled capsule a more efficient use of air and glycogen than swimming? If not…what, shark protection?
