German aerospace engineer Rudiger Koch set a new world record by staying underwater for 120 days in a submerged capsule near Panama’s coast. The 59-year-old broke the previous record of 100 days, held by American Joseph Dituri.
Koch stepped out of his 30-square-meter capsule in front of a Guinness World Records official, celebrating his achievement with champagne and a cigar before diving into the Caribbean Sea.
The underwater capsule had everything Koch needed to live, including a bed, toilet, television, computer, and internet.
An exercise bike helped him stay active. Food and medical supplies were sent through a tube connected to another chamber above the surface. Electricity came from solar panels, and a backup generator was also available. However, the capsule did not have a shower.
Speaking about his experience, Koch said he loved the calm and peaceful darkness underwater and the glow that would follow. He admitted feeling a bit sad that his time underwater had ended because he had enjoyed it so much.
This incredible achievement not only broke a world record but also highlighted Koch’s dedication and ability to adapt to life underwater for such a long time. His efforts showed what is possible with determination and the right technology.
