Transcript of Wave Power

Wave Power by Alex, Jonathan, Jesse, Shelby Waves Water Waves How we harness the energy? Advantages to OWC Disadvantages to OWC OWC Problem deep-water, long-wavelength sea waves carry a lot of energy speed of the wave depends on wavelength OWC Oscillating Water Column renewable source
unlimited
reasonable energy density
clean, without carbon emissions Needs large waves
Irregular waves pattern
Low-frequency waves incompatible
Expensive
Needs to withstand extreme weather conditions Calculate the power per unit wavefront length that can be obtained from deep-sea waves of amplitude 5.0 m and wave speed v=4.8 ms^-1. Point Absorbers Focusing Devices Overtopping Devices Your turn! Try the questions on the worksheet provided! OWC Formula P/L=(ρgA^2 v)/2 Factors:
Irregular Wave Patterns
Wave Speed
Amplitude
Direction P=Wm^-1
p=density=10^3 kgm^-3
g=gravity=9.81 Nkg^-1
A=amplitude
v=velocity=ms^-1
ρρρ Ans: 5.9 x 10^5 Wm^-1 How this can affect Canada Positive Factors:
Clean renewable energy
Harnesses a generally unused resource
Can be used across the East and West coast
Excess power can be sold OWC Oscillating Water Column
