How
does a marine turbine work ?
Marine current turbines work, in principle, much like submerged
windmills, but driven by flowing water rather than air. They can be
installed in the sea at places with high tidal current velocities,
or in a few places with fast enough continuous ocean currents, to
take out energy from these huge volumes of flowing water. These
flows have the major advantage of being an energy resource which is
mostly as predictable as the tides that cause them, unlike wind or
wave energy which respond to the more random quirks of the weather
system. |
