Point absorber
This uses a float that bobs up and down a pole to generate electricity
Point absorber
Vertical ‘pumping’
action
Oscillating wave converter
A paddle fixed to the sea floor is pushed back and forth by waves
Oscillating
paddle
Oscillating water column
Waves cause a water column to rise and fall, pushing air up and down and driving a turbine
Trapped air rotates
a turbine
Bulge wave converter
A water-filled rubber tube moves up and down with the waves, causing pressurised water to move along the tube to a turbine
Turbine
Tether
Higher pressure bulge
travels along the tube
