Germany has many large wind mills.
The gear boxes and generators are expensive.
The problem is there is no way of storing the energy.
When the wind blows there is not always a need for the power.

Here is a relatively low cost way of storing the energy.
The wind turbines are used as water pumps similar to oil pumps.
No gear box. No generator. The generator is replaced by
a simple large water tank on top of the pylon to store the energy.

The ground level water tank can be a lake. The water is recycled.

Many turbines can feed the same generator.

Do you have any idea of how HUGE that water tank would have to be?

1000 wind mills x 1000 is a million gallons.

When the wind is blowing water is flowing out of the pylon tanks to
feed the generator. When the wind starts to die down the valve is
closed and the tank then stores the water.

232 cubic inches per gallon as I recall

232,000 cubic inches. 134 cubic feet 10 by 10 by 1.3'. So my guess is it could be made
as large as 8000 gallons.

In fact there are many towns in the US with large water tanks on towers
which are  the main water supply for the town.

These could be retrofitted a wind turbine and this system.
Many more wind mills than three could feed one generator.


Do you have some calculations on the optimum size of the water tank?
