The system for converting kinetic energy from a fluid flow into mechanical energy, the method comprising the steps of Providing a turbine including first and second hydrofoils, each of the hydrofoils being able to move linearly in a heaving motion, and being able to oscillate about a span wise axis in a pitching motion. By coupling the heaving motions of the first and second hydrofoils to the pitching motions of the second and first hydrofoils respectively, with the pitch-heave motion phase being substantially equal to the inter-hydrofoil phase, the heaving motion of one of the hydrofoils thereby driving the pitching motion of the other hydrofoil. By transforming the heaving motion of the hydrofoils into a rotational movement of a shaft, with linear-to-rotary transmission means, the system can harness 261.8 watt power with 26.18% efficiency from water flowing with the velocity of 2 m/s.
