But there is a wrinkle… he’s not just going to journey from Robben Island to Capetown, he’s planning to do it underwater, in a human-powered, pressurized submersible along with three other “subwalkers.”
The project has already left the drawing board, with corporate and other partners including the Diver Alert Network and South Africa’s Council for Geoscience. The latter has already provided multibeam sonar bathymetric data and a workable route along a “tombolo,” or narrow underwater bridge.
There are going to be a lot of challenges to this project, including visibility, air supply, temperature control, currents, sharks and possibly the limits of human endurance itself. But here’s the best news… this unusual expedition is all in support of Nelson Mandela Children’s Hospital of Johannesburg.
