     FIELD OF THE INVENTION 
     The present invention belongs to the field of fluid driven motors and more particularly relates to a novel fluid driven motor device which is energy and heat efficient, and does not use a magnet or an armature coil. 
     BACKGROUND OF THE INVENTION 
     Development of energy efficient motors is of interest considering a variety of applications. An energy efficient motor minimizes heat losses. Fluid driven motors have several advantages such as being very energy and heat efficient, having lesser weight as compared to conventional electromagnetic coil based motors. Fluid driven motors as disclosed by present invention can have numerous applications such as in space flights where magnetic interference matter and weight matters. Also these motors are easy to assemble as compared to conventional motors since they do not involve armature coils, magnetic materials or conducting material plates. Also they do not overheat as copper coil based motors. 
     Below are given some of the known prior art indicating the importance of this area. 
     U.S. Pat. No. 7,614,861 entitled “Rotary fluid-driven motor with sealing elements” describes a static-fluid-pressure-driven rotary motor includes a casing, which defines a chamber having a fluid inlet and a fluid outlet, and at least one rotor assembly rotatably mounted within the casing. The rotor assembly includes a rotor, a plurality of barrier elements associated with, and extending outwards from, the rotor, and a resilient seal associated with at least an outer edge of each of the barrier elements. As the rotor turns about its axis of rotation, the outer edges of the barrier elements passing in proximity to a facing wall of the casing chamber against which the resilient seals for a sliding seal while accommodating variations in clearance between the outer edge of the barrier element and the facing wall of the casing. 
     U.S. Pat. No. 3,740,960 entitled “Elastic pressure fluid driven motor” describes an elastic pressure fluid driven motor consisting of a cylinder housing and a piston reciprocably guided in said housing. The piston is hollow and encloses a chamber which is fed with elastic pressure fluid from an elastic pressure fluid source. The piston and the housing are provided with openings and the housing is provided with distributing channels for distributing pressure fluid from the chamber into the cylinder during the return stroke and power stroke of the piston and vent it to the atmosphere, while the piston is reciprocated in the housing.

     In an exemplary embodiment of the invention, only one gas injection valve  23  and only one liquid injection valve  24  has been provided. However more than one such valve may be provided as a means for entry of an inert gas and a first coolant liquid in the motor casing chamber. The inert gas and the first coolant liquid are injected initially in predetermined proportions at the time of manufacturing and assembly.

The plurality of ray guns  14  are coupled to a power source  27 . The plurality of ray guns  14  are also electronically coupled a microcontroller based logic controller (not shown in the diagram) to control the frequency and duration of firing. As the ray guns fire sub-atomic rays such as laser beams directed towards the transparent, flexible membrane surface of the membrane cells, the second liquid L 2 , contained in the membrane cells immediately vapourizes and expands. The vapourization process happens extremely quickly, and leads to instantaneous expansion of the membrane cell. The expansion of the membrane cell causes it to move forward. As the vapour cools down owing to heat transfer to the coolant liquid L 1 , contained in the motor casing chamber, the membrane cell subsequently contracts. Immediately, thereafter the membrane cell faces the laser beams from the next ray gun, and undergoes almost instantaneous expansion once again. This cycle of expansion and contraction of the membrane cell happens repeatedly, one after another. The simultaneous forward movement of the membrane cells results in rotational movement of the shaft. This rotational movement of the shaft is harnessed with the help of gear device. The low viscosity of L 1  ensures minimum frictional losses and reduces the resistance and drag, during the motion of the plurality of membrane cells in the fluid mixture. The rotational speed of the shaft is governed by the timing and firing of the ray guns and can be pre-programmed. 
     In a preferred embodiment, the liquid L 2  contained in the membrane cell  15 , is an energy absorbing liquid. 
     In an alternate embodiment of the invention, the plurality of ray guns are positioned in the periphery of the motor casing chamber in a symmetrical pattern. The ray guns may be directed in as many directions to correspond to the number of directions of the membrane cells. In an alternate embodiments, the ray guns may be positioned vertically, one below another to form a straight line on the periphery of the motor casing chamber. Alternately, these may be arranged spirally, diagonally or any geometric pattern, symmetric or asymmetric. The pattern of the ray guns is designed to suit the firing of the laser beams to the flexible membrane of the membrane cells. 
     In an alternate embodiment of the invention, the ray guns are positioned in the periphery of the motor casing chamber in an asymmetrical pattern. 
     In another embodiment, the liquid contained in the membrane cell has the capacity to quickly absorb and dissipate the heat. 
     The pointed sharp solid member  22  of the membrane cell may be made of a material such as titanium. Preferably, the pointed sharp solid member  22  has a polished surface and is provided with a sharp edge so as to minimize frictional resistance. 
     Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only.
