German engineer sets underwater living world record

German aerospace engineer Rudiger Koch has set a new Guinness World Record by living underwater for 120 days without depressurization, The Guardian reported.

Koch, 59, spent the time in a 30-square-meter submerged capsule located 11 meters below the surface off the coast of Panama.

The previous record of 100 days was held by American Joseph Dituri. Koch’s achievement was confirmed by Guinness adjudicator Susana Reyes upon his emergence on Friday.

The capsule, powered by solar panels and equipped with modern amenities like a bed, toilet, TV, internet, and exercise bike, served as Koch’s home. A narrow staircase connected it to a surface chamber for food delivery and visitor access. Four cameras monitored his activities for verification.
