Olivier “Oli” Feuillette a noted “Kayak Legend” has been working on this project for a few years. Oliver’s new project is kayak that transforms into a human-powered submarine! The Youtube video shows the kayak being launched, paddled out and then transformed into human-powered submarine.
How does he breathe? In the Youtube comments Olivier Feuillette responded “Air comes from a cylinder, over flow comes out. For long dive co2 filter is used i am talking over 2/3 hours. The pressure is equalized so scuba rules are apply, same for depth.”
Pretty cool and it appears to work but the question is would you take this out?
