So wind turbines, often to be found at sea, farm the natural
energy of the wind and convert it into electricity to be used
on the land via a dynamo. But it is well known that energy
requirements fluctuate according to time of day and other
variables which the wind is largely oblivious to, meaning
power has to be stored or wasted when demand is low. Some
hyrdopower systems even pump water up a
mountain during off-peak times, storing it as potential
to unleash at peak times, though this clearly doesn't
a green solution.
Perhaps the answer could involve storing the energy inside
turbines themselves? If you look at them, the are like giant
straws, while the windmill at the top likely has the power to
suck water up through that straw to the top.
While demand is low, the turbines can switch modes and
pump, sucking sea water up inside
its shaft to be stored there. Later, when electricity is
required and the wind is dormant, the water can simply be
flushed down, turning another dynamo inside, with the flow
according to how much energy we need. Additional tanks or
height could be added to the top to accommodate extra
water. The turbines now essentially have their own
storing potential energy at its source for use at our
||A useful weight of water at a useful height will put
enormous additional strain on the supporting structure of
the wind turbine.
||A pump and a hydro-turbine built into each wind turbine
will involve much duplication of moving parts, many of
those moving parts being in constant contact with
corrosive salt water, even when not in use.
||The bulk of the structure which holds the head of water
may be so great as to impair the airflow on which the
wind turbines depend.
||Is it possible that all the turbines of a given wind farm
might share a single "water tower" with a single pump and
a single hydroelectric generator? Is it possible that they
could all be mechanically connected to this single
structure without extravagant wastage of energy in
mechanical transmission, using yet more high-precision
components which, again, must be protected against the

electrical current from the wind turbines, which would
then drive a pump at some quite separate hydroelectric

could just have the one & run it in the required direction.
On the other; yes, it would probably be more efficient to
have a "separate" hydro-battery system, driven
electrically by the wind-turbines.
||This idea would work better upside-down, pumping air into big underwater diving-bell-like contraptions.

that excess energy and pump the water into a lake
inland to store the water?

windmills would be pricey.

||But instead of a diving bell, or external tanks, turn the
whole thing into a
cylinder under water to utilize that water
pressure as a storage device. Taking the base,
which is presumably hollow anyway, shaping it into
a cylinder open to the ocean at the base. When
you need to recover that stored energy, just let
the water pressure push that cylinder back up.
||Thing is, you could dig a deep well and have that
cylinder go down hundreds of feet and have pipes
feeding the pressurized water to the base. That
pressure would increase the deeper the well.
