What is it ?
An Underwater windmill like a device that extracts power from the tides. Renewable
energy technologies are becoming an increasingly favourable alternative to conventional
energy sources to assuage fossil fuel related issues. Tidal energy offers a vast and
reliable energy source. This technology is similar to wind energy technology, with the
rotor blades driven not by wind power but by tidal currents. The gravitational pull of the
moon produces a swift tidal current, which spins the long blades of the turbine . Which
in turn produces electricity via different parts of underwater windmill . This Energy
derived from the moon that now helps to power a small arctic village.
NAME JUSTIFICATION
Why it is called as “underwater windmill” ?
"Basically it's like putting a windmill in the water," said Bjorn Bekken, a project manager
for Hammerfest Strom. Or as it’s looking like a wind mill & are installed on the ocean
floor and large river bed , that means these are under the water.
PRINCIPLE OF OPERATION
TYPES :
There are two types of underwater windmill
In simple a underwater windmill consists of a number of blades mounted on a hub
1 (together known as the rotor), a gearbox, and a generator.
The hydrodynamic effect of the flowing water past the blades causes the rotor to
rotate, thus turning the generator to which the rotor is connected via a gearbox.
2
The gearbox is used to convert the rotational speed of the rotor shaft to the desired
output speed of the generator shaft.
3
4 The electricity generated is transmitted to land through cables.
CONCLUSION
Tides play a very important role in the formation of global climate as well as the
ecosystems for ocean habitants. At the same time, tides are a substantial potential
source of clean renewable energy for future human generations. Depleting oil reserves,
the emission of greenhouse gases by burning coal, oil and other fossil fuels, as well as
the accumulation of nuclear waste from nuclear reactors will inevitably force people to
replace most of our traditional energy sources with renewable energy in the future .
Tidal energy is one of the best candidates for this approaching revolution. Development
of new, efficient, low-cost and environmentally friendly hydraulic energy converters
suited to free-flow waters. This type of machine, moreover ,can be used not only for
multi-megawatt tidal power farms but also for mini-power stations with turbines
generating a few kilowatts. Such power stations can provide clean energy to small
communities or even individual households located near continental shorelines, straits
or on remote islands with strong tidal currents.
