EGO: Personal Semi-Submarine Boat

Designed as the world’s first compact semi submarine, the “Ego” was created by the Korea based design firm at Raonhaje. 
This innovate water vessel gives passenger the opportunity to observe the underwater life in an enclosed core submerged under the water, and also an upper deck to enjoy the scenery on top of the ocean’s surface as well. The boat is powered by a 12 8-volt marine batteries, and can get about four to eight hours in the water on just one single charge depending on the travelling speed. Obviously the max speed will expend more energy than a cruising speed. As of right now, the personal semi-submarine is nothing more than a creative concept, but a great one never the less.
