Pump device for converting rotation into fluid flow

An apparatus for converting fluid flow into rotation, comprising:

• a first fluid conduit for accommodating transport of a first fluid and a second fluid different from the first fluid through said first fluid conduit, said first fluid conduit extending from a first open end to a second open end of the first fluid conduit, said first fluid conduit being coiled around a first axis of rotation;
• a second fluid conduit for accommodating transport of said first fluid and said second fluid through said second fluid conduit, said second fluid conduit extending from a first open end to a second open end of the second fluid conduit, said second fluid conduit being coiled around a second axis of rotation;
• a rotor coupled to said first fluid conduit and to said second fluid conduit in such a way that rotation of said rotor causes said first fluid conduit to rotate around said first axis of rotation and said second fluid conduit to rotate around said second axis of rotation;
• a first fluid separator for separating said first fluid from said second fluid, said first fluid separator being in fluid flow communication with the second open end of said first fluid conduit, and in fluid flow communication with the first open end of said second fluid conduit;
• and
• means for increasing pressure in said first fluid separator,
• wherein said first fluid separator is configured in such a way that when pressure is increased in said first fluid separator, said first and second fluids are displaced in said first fluid conduit and in said second fluid conduit to provide a net torque acting on said rotor, resulting in rotation of said rotor.
