In accordance with the present invention, a portable wave-swash & coastal-wind energy harvester, placed on a sea coast in swash zone captures energy contained in coastal waves and in coastal-wind through the utilization of wave turbines, wind turbines, and wave floats. Wave-float levers carrying wave floats and wave turbines, swing and maintain lower halves of wave turbines below water always. A gear system with one-way clutches transmits torque to an alternator to generate electricity. Flywheels maintain steady rotation of alternator shaft. A buoyancy chamber at the bottom produces reduction of weight of the unit when buoyancy chamber is emptied of water, and thereby enhances maneuverability of unit in water. Stabilization tanks at the top when filled with water provide extra weight and stability of the unit in its operating location. Units linked together in an energy farm combine their energy while forming a seawall-like barrier offering protection against coastal erosion.
