DESIGN AND ANALYSIS OF

GYROSCOPIC WAVE ENERGY CONVERTER

INTRODUCTION

• The Exploitation Of Wave Energy Fits Best Due To Exhaution Of Non-renewable Energy Resources

• Nowadays Sun, Wind And Biomass Energy Are The Most Dominant Sources Of Sustainable Energy

• Due To Premature Technology Wave Energy Is Relatively Unknown

• According To Linear Wave Theory E=ρgH2 /16
