3. Ocean Power – Rack & Rake Wheel
Introduction
The World is facing the continuous challenge of supplying enough energy to fuel economic growth.
Est. Ocean currents can meet 3000 times the current power needs of the entire World’s population.
Waves energy alone can potentially produce one third of the World’s electricity supply.

4. Ocean Power – Rack & Rake Wheel
Concept
M/S IP Management Pte Ltd has invented a double acting Racks & Rake Wheel fluid current energy converter device to tap kinetic energy of Ocean, river and wind currents.

8. Wave Power Reference - Wikipedia, the free encyclopedia
Waves are generated by wind passing over the surface of the sea.
As long as the waves propagate slower than the wind speed just above the waves, there is an energy transfer from the wind to the waves.

9. Wave Power Reference - Wikipedia, the free encyclopedia
Wave power formula
Example: Consider moderate ocean swells, in deep water, a few km off a coastline, with a wave height of 3 meters and a wave period of 8 seconds. Using the formula to solve for power, we get
meaning there are 36 kilowatts of power potential per meter of wave crest.

10. WAVE ENERGY CONVERTER IN SHALLOW WATER
The maximum power capture of a floating buoy is given by (Matt Folley, et al, )
P = ½ F .. x (1- ½ r)
When the motion is highly constrained, r ---> 0, then the power capture is proportional to the incident wave force, not the incident wave power intensity given above. This is evident for shallow water converters where the water depth is less than a quarter of the wave wavelength.
where
F - is the wave force
X - is the amplitude of motion
r - is the ratio of amplitude of motion to optimum amplitude of motion

11. Power Capture of a Floating Buoy
The power capture of a floating buoy is also given by (Evans, )
where
 - is the applied hydrodynamic damping coefficient (in Ns/m)
 - is the angular velocity (in rad/s)
X - is the amplitude of motion (in m)
