Patent ID: 7387728

Claim:
An animal powered mechanical water desalination device movable by a prime mover, the device comprising: (i) mechanical link means comprising a mechanical link for transmitting animal power to a speed increaser, said mechanical link means comprising an extended pipe; (ii) a speed increaser provided with an input shaft, the input shaft of the speed increaser being coupled to the mechanical link means such that the speed increaser converts animal power received from the mechanical link in the form of a first torque and speed to a second torque and speed, wherein the second torque is lower than the first torque and the second speed is higher than the first speed; (iii) high-pressure pump means, provided with a crankshaft which is connected to the output shaft of the speed increaser, for converting mechanical energy received from the speed increaser to hydraulic pressure energy and for generating a pressure of 300 psi; and (iv) osmotic means for using the hydraulic pressure energy from the high-pressure pump for converting brackish water into potable water.
