Abstract
A system for producing mechanical energy. In some embodiments, the system includes a first source providing a first fluid, a fluid pressurization device, a second source supplying a second fluid, a first motor, and a second motor. The fluid pressurization device draws in the first fluid from the first source and increases the pressure of the first fluid. The first motor is driven by the second fluid, the second fluid decreasing in pressure and the first motor powering the fluid pressurization device as the second fluid passes through the first motor. The second motor receives a mixture of the first fluid from the first motor and the second fluid from the fluid pressurization device, whereby the second motor produces the mechanical energy.
