The Australian marine biologist Lloyd Godson will attempt to stay in a 4m² under water home without coming up to surface for 14 days. With 2500 Wh, Godson will try to generate the largest amount of electricity ever produced by underwater cycling, surrounded by approx. 1300 fish and the eyes of the LEGOLAND visitors. An official Guinness World Records referee will confirm the world record by 13 April. Phaesun GmbH was asked to develop an optimum design and cabling for his autonomous power supply system. Phaesun has sponsored the underwater project with an energy storage system and a lighting project including four solar lamps.
