The sub will use a pedal-powered propulsion system based on a dolphin's tail. (It's already available in a swim-fin model that can propel swimmers fast enough to nearly leap out of the water like a whale.)
If he succeeds in making the 2,300-mile trip from Cape Verde to the Caribbean, Ciamillo may also help open a new window in marine science:
It may sound like a crazy stunt dreamed up by an adrenalin junkie, but the plan, dubbed the "Subhuman project", has attracted serious attention from marine biologists. That's because the sub, when it takes to the seas later this year, could for the first time allow them to explore the upper layers of the ocean silently and unobtrusively, revealing marine life as it has never been seen before.
