Pedal-powered sub!

[Taffycat]

Have you seen the pedal powered submarine HERE which will take two people to a depth of 30 meters?

Apart from two sets of pedals, controls are limited to a steering wheel and a few buttons to make operating the submarine as simple as possible....

....no one has previously built an enclosed, pedal-powered submarine for tourists because they could not generate the required power. However, MIT has patented an innovative design - utilising a phenomenon called the Coanda effect - which enables two people to create enough thrust.
