Wave Energy Presentation
Wave power
11HistoryThe first known patent to use energy from ocean waves
dates back to 1799, and An early application of wave power was a
device constructed around 1910 by Bochaux-Praceique to light and
power his house at Royan, near Bordeaux in France. It appears that
this was the first oscillating water-column type of wave-energy
device.was filed in Paris by Girard and his son.
(Oscillating water column devices can be located on shore or in
deeper waters offshore. With an air chamber integrated into the
device, swells compress air in the chambers forcing air through an
air turbine to create electricity.)2PotentialsThe western coastline
has the highest wave potential in the US (Northern CA)Floating or
completely submergedOffshore or onshore, on the seabedWave power at
deep sea ocean sites have 3-8 times more the wave power than
coastal sites (but more expensive)Most of prototypes have been
placed at or near shore
3Potential world wide: 2,000 TWh/year (10% of the world energy
consumption)
Reasons for un-utilization:Large amounts of money was required
for wave power to catch up with wind and solar. has cause of the
hype of wind and solar energys efficient electricity production
wave energy production lacked a lot of research and hence it is
commissioned by production companies.paled compared to wind and
solar energy.Also that beWith wave power, some research occurred
after the Arab oil embargo of the 1970s, but since then government
and commercial research and development into wave power

5Advantages & Disadvantages
6Advantages TheNot expensive to operate energy is free no fuel
Dependsneeded, noSome designs are noisy. withstand the strong
waves.But then again, so are waves, so any noise is unlikely to be
a problem Must be able to waste producedand maintain Can produce a
great deal of energyDisadvantages Needs a suitable site, where
waves are consistently strong on the waves sometimes youll get
loads of energy, sometimes almost nothingEconomic
Considerationsrequire the participation of some large companies,
such as GE or Siemens (both major.As with any energy source, the
fundamental roadblock toward more widespread deployment is cost. So
far, the wave energy field isfilled with small companiespicking off
small amounts of government funding where they can. It will likely
manufacturers of wind turbines) before wave power really gets
rolling, according to numerous experts. Those companies may be
waiting for the technology to sort itself out before investing, a
common dilemma in any nascent field
