German Engineer Attempts Record-Breaking 120 Days Living Underwater

Rüdiger Koch's underwater mission off Panama aims to test human adaptability to ocean habitats while breaking a world record.

Rüdiger Koch, a 59-year-old aerospace engineer from Germany, has been living in a 320-square-foot underwater capsule since September 26, aiming to spend 120 days submerged.
The attempt would surpass the current record of 100 days set by Joseph Dituri in 2023, with Koch scheduled to resurface on January 24, 2025.
Koch's underwater home, located 11 meters below the Caribbean Sea near Puerto Lindo, Panama, includes essentials like a bed, toilet, TV, internet, and an exercise bike, but lacks a shower.
Beyond the record, Koch seeks to demonstrate the potential for humans to live and expand into ocean environments, aligning with the broader vision of the ocean-based 'seasteading' movement.
The capsule doubles as an artificial reef, benefiting marine life, while Koch's team monitors his physical and mental health throughout the mission.
