Ocean Energy Harvesting to Generate Electricity Using a Raft

Ocean energy is tremendous and has a recent interest as a renewable energy resource. Moreover, because of global warming and the troubles of fossil fuel resources, searching for other sustainable energy sources will be very important. This study aims to investigate experimentally the possible benefits of energy that could be harvested from ocean (sea) energy in the Arabic golf far south of Iraq at Basra province. The main source of this energy is moving waves during the tidal and other reasons to generate electricity. The principle in designing this rig is the buoying force and how to invest it in generating electricity. The raft is fixed on the bottom of the sea, and when a wave occurs, the rope will pull (rotate) the roller, which then will rotate the generator shaft to generate the electricity. The results show very promising findings. Moreover, the electric generation during tidal was much more likely to generate electricity at other times. The accumulated (50 minutes) energy reached about 1200 Joule during the tidal. However, during the test without tidal, the energy harvesting within 50 minutes was just about 200 Joule.
