Abstract

Non-renewable energy such as petroleum, coal, gas and nuclear cannot be restored once it has been used. Many countries in the world are heavily dependent on the nonrenewable energy and polluting sources to generate electricity. This would cause the greenhouse gas emissions and would have adverse effects on the country due to climate changes. Generally, approximately 75% of earth is covered by the ocean and for that reason, many investors starting to develop a technology for harnessing the ocean wave. Wave energy is a form of renewable energy available on the earth where converting the ocean wave energy into electricity. In this project, it will study and develop the "Portable Power Supply from Wave Energy". Therefore, it will employ a basic concept of Faraday's Law. Wave energy is use as a prime mover for this project where it helps the solenoid to move right and left of permanent magnet to generate electricity. The magnetic field of magnets is cut by the solenoid and current is induced in the coil. The amount of induces current is depends on the number of wire turns, the number and the strength of magnet and the relative movement of magnet. Thus, this project is attempted to use a permanent magnet (Neodymium Iron Boron) and solenoid with 4000 turns of wire turns. The movement of wave will cause solenoid move to the right and move to the left of permanent magnet and cuts the magnetic fields and simultaneously produce alternating current (AC) voltage and then convert to direct current (DC) by using voltage multiplier. It is therefore, this project is very useful to supply electricity for small load such as LED lighting for outdoor activities likes camping and picnic.
