Frank M Rinderknecht, the 52-year-old automobile visionary and boss of Swiss automaker Rinspeed, has turned a dream into reality with his 'sQuba.' Rinspeed sQuba is the most exciting thing at this year's Geneva Motor Show and is creating many a ripple. sQuba is the world's first real submersible car that can 'move like a fish underwater'. It can dive up to 32.8 feet (10 mt) below the surface of the water and can move at a sedate 1.8 miles per hour. The sQuba has an open cockpit for 'safety reasons' (so that people can get out easily anytime in case of an emergency). The occupants of the car have to breathe compressed air through built-in scuba masks. sQuba is an electric car that uses rechargeable lithium-ion batteries and 3 electric motors for propulsion. It is a zero-emission car as documented by the rotating license plate in the rear. It produces no exhaust emissions. The 'sQuba's' filling station is the water reservoir.? It is no surprise
