For most of us, the world deep below the ocean's surface remains a place we have only had the pleasure to experience vicariously, primarily through watching nature documentaries. It's not as if we can just hop in a submarine and go to take a look.
A Russian company's plan to market a two-seater submarine driven by pedal power to the tourist. If it bacome true the we will be able to visit the nature of the deep sea.
Its like a bicycle, according to MIT, its underwater craft differs from comparable small tourist submarines in overcoming some of the difficulties associated with the use of traditional screw propulsion and accumulator batteries to generate motion. These kinds of submarine tend to be complex to control and service and require specialized training to operate.
Wenerally, submarines require a propulsion capacity of about 2.5-5 kW to maintain an underwater speed of 2-3 knots. The average person riding a bicycle struggles to generate a propulsion capacity greater than 0.2-0.4 kW over a one to three hour time period. This means a pair of furiously pedaling tourist couldn't muster enough power to propel an underwater vehicle.
But MIT (Marine Innovation Technologies) has overcome the mathematical impossibility through both its innovative design as well as something called Coanda effect. With both these elements in play, an avarage person, with the help of pedals, can generate the necessary underwater speed of between two and three knots, for to four hours, to propel the company's two-passenger UV.
