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.
“We have tested Gordon’s bicycle in our company and designed the power supply for the lighting and the operation of a notebook”, Phaesun Managing Director Tobias Zwirner explains.
Phaesun connected a solar module directly with four Sundaya Ulitium LED lamps over a junction box.
8 kilojoule (kJ) energy per hour are sufficient to achieve 240 lumen of light output for 6 hours. The electronic system and a lithium-ion storage battery are already integrated in the lamps.
The energy generated by cycling is therefore transferred over an energy storage system to Godson’s notebook, his medium to communicate with the outside world.
