German Engineer Sets World Record with 120 Days Underwater

Rüdiger Koch's underwater mission off Panama highlights ocean conservation and personal endurance.

Rüdiger Koch, a 59-year-old German engineer, lived for 120 days in a 30-square-meter capsule 11 meters underwater near Panama, setting a new Guinness World Record.
The previous record of 100 days, held by American Joseph Dituri, was surpassed under the supervision of Guinness official Susana Reyes.
Koch's underwater habitat was equipped with basic amenities, including a bed, computer, and exercise bike, but lacked air conditioning and a shower.
Despite challenges like heat, limited space, and invasive marine species, Koch maintained morale with projects, wine, and whiskey, while observing marine life through the capsule's windows.
Koch used the record attempt to advocate for ocean conservation, emphasizing the need to view the sea as a home rather than a resource or waste site.
