The inspired Platypus Electric Underwater Exploration Craft

The inspired Platypus Electric Underwater Exploration Craft: "The French-designed Platypus is a new and immensely practical two-person electric underwater exploration concept designed to travel for eight hours above the water at 10-12 knots (18.5-22.2 km/h), or below the water at 3-4 knots (5.5-7.5 km/h). Most importantly, it offers a safe and stable below-water platform that requires no operating equipment to be worn by the pilot or passenger other than masks because the pontoons contain an integrated compressor which supplies air via hoses."
