- 3. INTRODUCTION Wave power is the energy carried by the wind waves and consumption of that energy to do useful work. The amount of energy in a wave depends on its height and wavelength as well as the distance over which it breaks. In average ocean conditions, the average energy density per unit area of sea surface waves is proportional to the wave height squared.

- 22. FURTHER PROGRESS Have to add more geometry to Turbine to reduce the friction Have to consider 3 point location (maximum displacement, minimum displacement , average displaement) because in low spped range wells turbine with 0 degree tilled angle NACA0015 blades gives maximum output. Need to conduct LAB testing after that I can reduce the error. Have to calculate he reaction time of circuit that define the distnce between the turbine and sensor.
