An anonymous reader writes: The Ictineu 3 will be the 10th deepest diving submersible in the world when it is launched later this year. Compared to its deep diving peers, including Russia's Mirs, Japan's Shinkai 6500, the US's Alvin,and Cameron's Deep Sea Challenger submersibles, the Ictineu 3 was developed on a shoestring budget. The management partners are self-taught, without formal engineering education. Instead of massive government grants, the project has been funded by a trickle of small grants, sponsorships, and private donors. Along with Karl Stanley, the Ictineu team are heroes to the DIY submariners of the world.
