|Title||Development of Wave Energy Conversion Device - Gaza Shoreline|
Most conventional methods of energy production are contributing to serious environmental problems and, therefore; cleaner energy resources are increasingly needed. Renewable energies are those clean energy resources which are renewed by the nature again and again and their supply is not affected by rate of consumption. Wave power technology has been around for nearly thirty years and is considered as a serious competitor among the renewable energies. During this period many wave energy devices have been invented and used, and some are only proposed. The present work introduces one of such energy conversion devices. The main theme of the present prototype is based on converting the kinetic and potential energies, that exist in moving sea waves, into potential energy as the water is stored in an elevated reservoir. The stored water can then be fed through a turbine (and a generator) to generate electricity. Based on assumed electrical-power requirement (1.5 kWh per day) and available conditions, the present model was designed, analyzed, fabricated, and finally tested onGazashoreline for few days. Several modifications were introduced whenever needed. These modifications were adopted according to results obtained during three different experimental phases. The present device produced average filling rates, at 15-m head, that would generate about 55% of the assumed power with a device efficiency of 85.7%. The preset study, also, indicated that short and wide pistons should be used in similar applications. Results obtained are very satisfactory and encouraging to continue research in this field.
