Main function of wave energy buoy is chenging wave enrgy in to electrisity. The wave energy buoy consist of coppper coil,magnetick shaft , fibreglass container,cable. First of all to start using this device we have to place copper coil int buoy floats on the sea surface, nextly we have to attached magnetick shaft to seabad by cable. One of this buoy can give as 100W power.Now i will try to explane how does it works: Sea waves oscillates.This oscillating montion moves magnetick shaft - it stars moving up and down . This shaft by moving through copper coil induct electric current.This device dosn`t creat any pollution ,dosn`t use fossil fuels . Wave powers are renowable energy so it is god for enviroment.But this technology have also defect to provide power supply to city we have to use 500 buoys. This number of bouys can distub for ships and fishs.
