Episode notes
Hydrogen Dive Test
- Richard Harris and Craig Challen tested hydrogen diving at 245 meters in an underwater cave.
- They sought to break the depth barrier by using hydrogen.
Sheck Exley's Diving Legacy
- Sheck Exley, a math teacher, became a diving icon, pushing the limits of deep diving.
- He achieved record-breaking dives, exceeding military and commercial professionals.
Challenges of Deep Diving
- Breathing regular air at 40 meters causes inert gas narcosis (the Martini effect).
- Deeper than that, oxygen becomes toxic, so divers started using helium mixtures.
