The German inventor developed a manual underwater “jet pack”
German inventor Un Jong Pak developed an underwater jet pack, which he named Scubalec. The device consists of two small water-jet engines connected to the battery. The device is fastened to the left forearm.
Movement in the underwater position is provided by turbines, sucking water and emitting it through the nozzle. By the way, squid moves in a similar way . Adjustment of the engine operation is performed with the thumb using a special handle. You can specify the direction of motion simply by changing the position of the hand.
One charge of a lithium-ion battery with a capacity of 7600 mAh is sufficient for 10-12 minutes of continuous operation.
Un Yong Pak has posted the Scubalec project on the collective collection site of the Kickstarter facility. The cost of an instance of the device at this stage is $ 297. In the future, the estimated retail price will increase to 427 dollars.
